Amazon PPC Keyword Research: How to Find, Evaluate, and Use Keywords That Convert

Amazon PPC keyword research is the process of finding and prioritizing the search terms most likely to bring relevant traffic, better conversions, and profitable sales through Amazon Ads.

It helps you decide which shopper queries are worth targeting, which ones should be filtered out, and which terms fit your product, listing, and margin goals.

This matters because not every keyword with traffic is worth your budget. A keyword only has value when it matches shopper intent, clearly fits the product, and can convert at a cost your business can afford.

Better keyword research improves traffic quality, reduces wasted spend, and gives you more control over campaign performance. This is one reason many sellers also turn to an Amazon agency for stronger keyword targeting, better campaign structure, and cleaner optimization decisions.

Amazon Ads highlights the business impact of paid visibility on the marketplace. According to Amazon Ads, advertisers who used Sponsored Products saw 34% more sales growth on average than those who did not within four weeks after adoption. That does not mean every keyword performs well, but it does show that structured targeting and optimization can drive measurable growth.

In this guide, you will learn how to find Amazon PPC keywords, evaluate them properly, identify negative keywords, and align keyword research with campaign structure for both new and mature products. Keyword research is one part of the broader Amazon PPC strategy, and the goal is to build a keyword plan that improves relevance, protects ad spend, and supports profitable growth. 

Key Takeaways

• Amazon PPC keyword research helps you find profitable traffic, not just more traffic. The goal is to target search terms that match shopper intent, product relevance, and business economics.
• Good keyword research separates discovery from evaluation. First, you find keyword ideas. Then you judge them based on relevance, demand, intent, competition, conversion potential, and profitability.
• Keyword relevance matters before volume. High-traffic terms can waste budget if they do not match the product, listing, or shopper expectation closely enough.
• Search term data is one of the most important sources for keyword decisions. It shows what shoppers actually typed, which helps you find converting queries and spot wasted spend.
• Negative keywords are part of keyword research, not a separate cleanup task. They help block irrelevant or low-value traffic and improve campaign efficiency.
• Amazon PPC success depends on structure, not just keyword lists. Keywords should be grouped and tested in the right campaign types so you can control bids, search terms, and scaling more effectively.
• Sponsored Products can create measurable growth when used well. Amazon Ads says advertisers using Sponsored Products saw 34% more sales growth on average within four weeks after adoption.

Let’s get into the details.

Why Amazon PPC Keyword Research Matters and Its Types

Amazon PPC keyword research matters because it helps you target the right shopper searches. This improves traffic quality, reduces wasted spend, and gives your campaigns a stronger chance to convert.

A keyword is only useful when it matches the product, the listing, and the shopper’s intent. High search volume alone does not make a keyword valuable. Good keyword research helps you focus on terms that support relevance, efficiency, and profitability.

It also helps you build better campaigns. When your keyword targeting is clear, it becomes easier to test match types, find winning search terms, add negative keywords, and scale what works.

Main Types of Amazon PPC Keywords

• Branded keywords include your brand name. These often convert well when shoppers already know your product.
  Example: Nike running shoes
• Generic keywords describe the product category without a brand name. These help with discovery but often need closer control.
  Example: running shoes
• Long-tail keywords are more specific searches with extra detail. These often show clearer buying intent.
  Example: women’s waterproof trail running shoes
• Competitor keywords include another brand name. These can improve visibility but need careful testing.
  Example: Adidas running shoes
• Product attribute keywords focus on features like size, color, material, or pack count. These help match ads to specific product preferences.
  Example: stainless steel water bottle 32 oz

Why These Keyword Types Matter

• Branded keywords support brand defense and conversions.
• Generic keywords help attract new shoppers.
• Long-tail keywords often improve relevance and conversion potential.
• Competitor keywords help you show up in competitive searches.
• Product attribute keywords connect your ad to clear product preferences.
• Use-case keywords align your product with real customer needs.

Amazon PPC keyword research is not about collecting more keywords. It is about choosing the right keyword types for the right campaign goal.

How to Find and Evaluate Amazon PPC Keywords

Amazon PPC keywords should be found from real shopper language and then evaluated based on relevance, intent, competition, conversion potential, and profitability. The goal is not to collect the biggest keyword list. The goal is to find keywords that can bring the right traffic at a cost your business can afford.

Step 1: Find Seed Keywords

Seed keywords are the main words that describe your product.

Start with the most basic terms a shopper would use to search for your item on Amazon. These usually come from:

• The product name
• The category
• The main feature
• The primary use case
• The target buyer

Ask simple questions:

• What is the product?
• What problem does it solve?
• Who is it for?
• What makes it different?

If you sell a stainless steel water bottle, your seed keywords might include:

• stainless steel water bottle
• insulated water bottle
• reusable water bottle
• gym water bottle

These are not your final PPC keywords. They are your starting point.

Why this matters: If your seed keywords are weak or too broad, the rest of your keyword research will also be weak.

Step 2: Expand Keywords with Amazon Autocomplete

Amazon autocomplete shows real search phrases that shoppers already use.

Type each seed keyword into Amazon’s search bar and study the suggestions. These suggestions often reveal the exact way people search by:

• Size
• Color
• Feature
• Material
• Audience
• Use case

For example, if your seed term is insulated water bottle, Amazon may suggest:

• insulated water bottle with a straw
• insulated water bottle for the gym
• insulated water bottle for kids

These longer searches are often more useful because they show clearer shopper intent.

Why this matters: Autocomplete helps you find keywords based on actual Amazon search behavior, not guesses.

Step 3: Analyze Search Term Reports

Search term reports show the actual shopper searches that triggered your ads.

This is one of the most valuable keyword research sources because it comes from real campaign data. It helps you find:

• Search terms that convert
• Search terms that get clicks but no sales
• Terms worth moving into an exact match
• Terms worth adding as negative keywords

This step is also where many sellers discover the difference between a keyword they targeted and the search term a customer actually used. That difference often reveals both winning opportunities and wasted spend.

Why this matters: Search term reports help you make keyword decisions based on real performance, not assumptions.

Step 4: Research Competitor Keywords

Competitor research helps you find important terms already used in your category.

Review competitor:

• Titles
• Bullet points
• Product descriptions
• A+ content
• Storefront language
• Visible ad copy

Look for repeated phrases tied to:

• Product type
• Core features
• Customer needs
• Use cases
• Positioning

For example, if many top listings repeat terms like BPA-free, leak-proof, or fits cup holder, those terms may reflect how shoppers search and compare products in that niche.

Do not copy competitor keywords blindly. Only keep terms that actually match your product.

Why this matters: Competitor research helps you spot keyword opportunities and category language you may have missed.

Step 5: Mine Product Listings, Reviews, and Q&A

Listings, reviews, and Q&A reveal how customers talk about the product in real life.

Customers often use more natural and practical language than brands do. This is useful because PPC keyword research should reflect the way buyers search, not just the way sellers write.

Look for:

• Pain points
• Common complaints
• Desired features
• Benefits shoppers mention often
• Use-case phrases
• Wording customers repeat

You may find phrases like:

• easy to clean
• keeps water cold all day
• fits in a car cup holder
• good for the gym
• does not leak

These can become useful product attribute keywords or use-case keywords.

Why this matters: Customer language often reveals high-intent keyword ideas that standard keyword tools may miss.

Step 6: Validate Keywords with PPC Tools

PPC tools help you expand, organize, and compare keyword ideas faster.

They are useful for:

• Finding related keyword suggestions
• Estimating demand
• Spotting keyword clusters
• Comparing keyword variations
• Identifying possible competition signals

This helps you move faster, especially in larger categories. But tool data should support your decision, not make the decision for you.

A keyword is only worth testing if it makes sense for:

• The product
• The listing
• The offer
• The campaign goal

Why this matters: Tools can speed up research, but judgment still matters more than raw keyword volume.

Step 7: Evaluate Keyword Relevance

Keyword relevance shows how closely the search term matches your product and listing.

This is the first and most important filter. Before you look at traffic or CPC, ask:

• Does this keyword clearly describe the product?
• Would the shopper expect the exact product I am offering?
• Does my listing support this term well?

Check relevance against:

• Product type
• Variant
• Size
• Material
• Audience
• Feature set
• Title
• Images

For example, a water bottle may be relevant, but a glass water bottle is not relevant if you sell stainless steel bottles.

Why this matters: Irrelevant keywords waste spend, lower conversion rates, and make campaign data harder to trust.

Step 8: Evaluate Search Volume

Search volume shows how much demand a keyword gets.

A keyword needs enough demand to justify testing, but volume should never be judged alone.

A broad keyword may get a lot of traffic and still perform badly. A lower-volume keyword may bring fewer clicks but stronger conversions because it matches the product better.

Instead of asking, “Is this keyword big enough?” ask:

• Is there enough demand to test it?
• Is the traffic likely to be relevant?
• Does the volume fit the campaign goal?

Why this matters: Good keyword research balances traffic opportunity with traffic quality.

Step 9: Evaluate Purchase Intent

Purchase intent shows how ready the shopper is to buy.

Some keywords reflect general browsing. Others show that the shopper already knows what they want.

Compare these:

• water bottle
• insulated water bottle
• stainless steel water bottle 32 oz
• stainless steel water bottle for gym

As a keyword becomes more specific, buyer intent usually becomes clearer.

High-intent keywords often include:

• Size
• Material
• Audience
• Compatibility
• Pack count
• Use case
• Feature modifier

These terms often convert better because the shopper is searching with more direction.

Why this matters: Strong purchase intent usually leads to better conversion efficiency and less wasted spend.

Step 10: Evaluate Competition and CPC

Competition and CPC show how hard and how expensive a keyword may be to target.

Some keywords look attractive because they have high volume, but they may also have:

• Aggressive bidding
• High CPC
• Strong competition from established brands
• Weak margin room

Ask:

• Can I afford traffic on this keyword?
• Is the keyword too competitive for my current product stage?
• Does the product page have enough strength to compete?

A competitive keyword is not always bad. It just needs stronger justification.

Why this matters: A keyword is only useful if the expected cost still fits the business model.

Step 11: Evaluate Conversion Potential

Conversion potential shows how likely a keyword is to turn clicks into sales.

This is where you connect the keyword to the listing. A keyword may be relevant and still fail if the product page does not support the shopper’s expectation.

Review:

• Title clarity
• Image match
• Feature alignment
• Review quality
• Pricing position
• Offer strength
• Retail readiness

For example, if a keyword suggests a premium product but your images, reviews, or pricing do not support that expectation, conversions may stay weak.

Why this matters: Keywords do not convert by themselves. The listing has to finish the job.

Step 12: Evaluate Profitability Fit

Profitability fit shows whether the keyword can work within your margin target.

This is the final filter. Even a relevant, high-intent keyword may not be worth scaling if the ad cost is too high.

Review:

• Expected CPC
• Likely conversion rate
• Average order value
• Break-even ACoS
• Target ROAS
• Product margin

A practical rule is simple: a keyword should not just generate sales. It should generate sales at a cost the business can sustain.

Why this matters: Amazon PPC keyword research should end with financial fit, not just traffic or orders.

What Metrics Matter in Amazon PPC Keyword Research

The most important metrics in Amazon PPC keyword research are traffic metrics, conversion metrics, and profitability metrics. Together, they show if a keyword is getting visibility, bringing qualified traffic, converting into sales, and staying within your cost targets.

A keyword is not strong just because it gets impressions or clicks. It needs to bring the right shopper, convert at a reasonable rate, and work within your margin.

1. Traffic Metrics

Traffic metrics show how much visibility and engagement a keyword is getting.

The main traffic metrics are:

• Impressions: How often your ad appears for a keyword. This helps you judge search demand and visibility.
• Clicks: How many shoppers clicked your ad? This shows whether the keyword is driving actual traffic.
• Click-through rate (CTR): How often shoppers click after seeing the ad. A stronger CTR usually means the keyword and listing are matching the shopper’s intent better.
• Cost per click (CPC): How much you pay for each click. This shows how expensive traffic is for that keyword.

Metric	What it shows	Why it matters
Impressions	Keyword visibility	Shows demand and auction presence
Clicks	Traffic volume	Shows shopper engagement
CTR	Click quality	Helps judge relevance
CPC	Traffic cost	Affects efficiency and scale

Example:
If a keyword gets high impressions but low CTR, it may be too broad or weakly matched to the product. If CPC is high, the keyword may still struggle even if it gets clicks.

2. Conversion Metrics

Conversion metrics show how well a keyword turns clicks into sales.

The main conversion metrics are:

• Orders: How many purchases came from the keyword?
• Conversion rate: How often clicks turn into orders. A stronger conversion rate usually means better product-query fit.
• Attributed sales: The sales value generated from ad clicks on that keyword.

These metrics help answer:

• Is this keyword bringing buyers or just traffic?
• Does the search term match shopper intent?
• Does the listing support the keyword well?

Example:
A broad keyword like water bottle may get traffic, but stainless steel water bottle 32 oz may convert better because the search is more specific.

3. Profitability Metrics

Profitability metrics show whether a keyword is worth keeping or scaling.

The main profitability metrics are:

• ACoS: How much ad spend is used to generate sales.
• ROAS: How much revenue you generate for each dollar spent on ads.
• Spend without sales: Helps you find keywords wasting budget.
• Keyword-level cost efficiency: A combined view of spend, sales, conversion rate, ACoS, and ROAS.

Metric	What it shows	Why it matters
ACoS	Ad cost against sales	Helps judge efficiency
ROAS	Revenue from ad spend	Helps compare return
Spend without sales	Unproductive spend	Helps spot waste quickly
Keyword-level efficiency	Full performance view	Helps scaling and pruning

Example:
A keyword can have a good CTR and still fail if CPC is high and the conversion rate is weak. That is why profitability matters as much as traffic.

How to Use These Metrics Together

You should judge keywords by looking at all three metric groups together.

• Traffic metrics show if the keyword is being seen and clicked.
• Conversion metrics show if that traffic is turning into orders.
• Profitability metrics show if the keyword makes financial sense.

For example:

• High impressions + low CTR often means weak relevance.
• Good CTR + low conversion rate often means weak product-page fit or weak buyer intent.
• Sales + poor ACoS often means the keyword needs tighter cost control.

A good Amazon PPC keyword is not just visible. It also needs to convert and stay profitable.

How to Find Negative Keywords and Avoid Wasted Spend

Negative keywords help you stop ads from showing for irrelevant, low-value, or weak-converting searches. This protects ad spend and improves traffic quality.

In Amazon PPC, not every customer search term that triggers your ad is worth paying for. Some searches are too broad. Some describe a different product. Some bring clicks but no orders. Negative keyword targeting helps filter that traffic before it keeps wasting budget.

The main goal is simple: block search terms that do not match your product, do not match the shopper’s likely intent, or do not make sense financially.

1. Start with Search Term Reports

Search term reports are the best place to find negative keywords because they show the actual customer search terms that triggered your ads.

Review your reports to find:

• Irrelevant search terms
• High-spend terms with no sales
• Weak-intent queries
• Mismatch terms
• Repeat search terms that hurt campaign efficiency

This is where keyword research and negative keyword strategy connect directly. Search term analysis helps you see which queries should be harvested and which should be excluded.

2. Look for Irrelevant Search Terms

Irrelevant search terms are queries that do not closely match your product.

These may include the wrong:

• Product type
• Material
• Size
• Audience
• Feature
• Use case

Example:
If you sell a stainless steel water bottle, searches like plastic water bottle, glass water bottle, or protein shaker bottle may not be relevant enough to keep paying for.

If the search term clearly brings the wrong shopper, it is often a good negative keyword candidate.

3. Look for High-Spend Terms With No Sales

High-spend search terms with no sales are often signs of wasted ad spend.

A term should not be blocked after only a small amount of data, but if it keeps spending and still produces no orders, it needs a closer review.

Ask:

• Is the term truly relevant?
• Is shopper intent too weak?
• Is the keyword too broad?
• Is the CPC too high for the product margin?
• Is the listing failing to support this query?

If the term is both expensive and weak on performance, it may belong in your negative keyword list.

4. Look for Mismatch Terms

Mismatch terms are searches that seem related but still bring the wrong type of traffic.

These are dangerous because they can look close enough at first, but still fail to convert well.

Example:
If you sell a premium bottle, a search like cheap water bottle may be a poor fit. If you sell a large bottle, a query like kids mini water bottle may also be mismatched.

These terms often create wasted spend quietly because they still get clicks, but not the right clicks.

5. Use Negative Exact and Negative Phrase Properly

Negative exact blocks one specific search term, while negative phrase blocks that phrase and related variations containing it.

Use negative exact when:

• One specific search term is underperforming
• You do not want to block related searches too broadly

Use a negative phrase when:

• The same poor phrase appears across many variations
• The phrase repeatedly brings weak traffic

Here is a simple comparison:

Negative match type	What it blocks	Best use case
Negative exact	One specific search term	When only one query is the problem
Negative phrase	The phrase and related variations	When a repeated phrase drives poor traffic

Example:
If a cheap water bottle performs badly, negative exact may block only that exact query. If the phrase cheap water keeps showing up in weak search terms, a negative phrase may be the better choice.

6. Avoid Blocking Useful Traffic Too Early

Negative keywords should reduce waste, not block good discovery.

Do not add negatives too aggressively just because a keyword has not converted yet. A search term may still deserve more testing if:

• Click volume is still low
• The product is new
• The campaign is still in discovery mode
• The listing is being improved
• The bid is the real problem, not the keyword itself

This matters most for new products and early Sponsored Products campaigns, where search term harvesting is still in progress.

A Simple Process to Find Negative Keywords

Use this process regularly:

1. Review search term reports.
2. Find irrelevant search terms.
3. Find high-spend terms with no sales.
4. Spot mismatches in product type, audience, feature, or intent.
5. Choose a negative exact or negative phrase.
6. Keep monitoring results after adding negatives.

This process helps improve traffic filtering without blocking useful shopper searches too early.

Common Amazon PPC Keyword Research Mistakes

The most common Amazon PPC keyword research mistakes happen when advertisers chase traffic without checking relevance, shopper intent, and profitability. A keyword can get impressions and clicks, but still perform badly if it does not fit the product, listing, or campaign goal.

• Chasing search volume without checking relevance: High search volume does not make a keyword a good fit. Broad terms can bring traffic, but they often waste spend if the product-query match is weak. Example: water bottle may be too broad for a premium insulated bottle with a specific use case.
• Ignoring shopper intent: Some search terms show browsing intent, while others show stronger buying intent. If you ignore that difference, you may pay for traffic that is less likely to convert. More specific keywords often show better purchase intent.
• Ignoring search term reports: Search term reports show the actual customer search terms that triggered your ads. If you do not review them, you miss converting queries, wasted spend terms, and negative keyword opportunities.
• Weak negative keyword control: Poor negative keyword management allows irrelevant or low-value traffic to keep spending the budget. This reduces traffic quality and makes campaign data harder to trust.
• Skipping profitability review: A keyword is not strong just because it gets sales. You still need to check CPC, conversion rate, ACoS, ROAS, and margin. Some keywords generate orders but still fail financially.
• Separating keywords from listing relevance: Keywords do not work alone. If the title, images, price, reviews, and product details do not support the search term, the conversion rate can stay weak even when targeting is correct.
• Using the same keyword strategy for every product stage: New products usually need broader discovery and tighter filtering. Mature products usually rely more on historical search term data, exact-match scaling, and branded keyword defense. Using the same keyword plan for both often leads to weak decisions.

To avoid these mistakes, review relevance before volume, check shopper intent, use search term reports regularly, control negatives carefully, judge keywords by profitability, and make sure the listing supports the traffic you are buying.

How Keyword Research Changes for New vs Mature Products

Amazon PPC keyword research changes by product stage because new products need discovery, while mature products need refinement, scaling, and efficiency.

A new product usually does not have enough search term data, conversion history, or clear keyword winners yet. A mature product already has performance data, which makes keyword decisions more precise. That is why the same keyword strategy should not be used for both.

Product Stage	Main Keyword Research Goal	Main Focus
New Product	Discovery and validation	Find relevant search terms, test intent, filter waste
Mature Product	Scaling and efficiency	Expand winners, improve control, protect profitability

Keyword Research for New Products

New products need broader keyword discovery because there is not enough historical data yet.

At this stage, the goal is to find:

• Relevant search terms
• Early conversion signals
• Negative keyword opportunities
• Useful keyword types for future scaling

New products usually rely more on:

• Seed keywords
• Amazon autocomplete
• Competitor keyword research
• Product attribute keywords
• Use-case keywords
• Search term harvesting from automatic and broad match campaigns

For example, if a new product is a stainless steel water bottle, the early keyword strategy may include broader but relevant terms like:

• insulated water bottle
• gym water bottle
• reusable water bottle
• stainless steel bottle

This helps the advertiser learn how shoppers actually search before moving too aggressively into exact match scaling.

New product keyword research should stay tightly filtered for relevance. Broad discovery is useful, but weak traffic can waste budget quickly if negative keyword control is ignored.

Keyword Research for Mature Products

Mature products need more keyword refinement because there is already enough performance data to guide decisions.

At this stage, the goal is to:

• Expand winning search terms
• Improve keyword targeting efficiency
• Move proven queries into exact match
• Strengthen branded keyword coverage
• Reduce wasted spend from weak terms

Mature products usually rely more on:

• Historical search term reports
• Exact-match keyword expansion
• Branded keywords
• Long-tail keywords with strong conversion history
• Profitability review at the keyword level
• Tighter bid and campaign control

For example, if a mature product already converts well for a stainless steel water bottle 32 oz, that keyword may deserve its own exact-match ad group or campaign with a more refined Amazon PPC bidding strategy based on actual results.

This stage is less about finding random new terms and more about scaling proven customer search terms that already match shopper intent, listing relevance, and margin goals.

How to Align Keyword Research With Campaign Structure

Keyword research should align with campaign structure because campaign structure decides how keywords are tested, controlled, and scaled.

A simple way to structure this is:

• Use discovery campaigns for keyword testing. This is where different Amazon PPC match types help you control how broadly or narrowly you target shopper searches. Broad match, phrase match, and automatic targeting can help you find new customer search terms and learn how shoppers actually search. 
• Move proven search terms into exact-match campaigns. When a keyword shows strong relevance, conversion rate, and acceptable ACoS, placing it in exact match gives you better bid control and cleaner performance data.
• Keep branded keywords separate. Brand terms usually have different search intent, click-through rate, CPC, and conversion behavior than generic keywords, so they should not be mixed into the same campaign.
• Keep competitor keywords separate. Competitor terms often cost more and convert differently, so isolating them makes performance easier to measure and control.
• Use negative keywords to guide traffic. If a search term is irrelevant or wasting spend in a discovery campaign, add a negative exact or negative phrase where needed to stop poor traffic from repeating.
• Group keywords by campaign goal. Discovery keywords help you learn. Exact-match keywords help you scale. Branded keywords help protect brand traffic. Competitor keywords help test competitive visibility.

Here is the key idea:

Campaign purpose	Keyword type	Main goal
Discovery	Broad phrase, automatic	Find new search terms
Control and scaling	Exact match	Scale proven keywords
Brand defense	Branded keywords	Capture brand searches
Competitive testing	Competitor keywords	Measure competitor traffic

For example, if a broad-match keyword starts generating a profitable customer search term, that search term can be moved into an exact-match campaign for tighter control.

In simple terms, keyword research tells you what to target, and campaign structure decides where to place it and how to manage it. This makes Amazon PPC easier to optimize and easier to scale.

Final Thoughts

Amazon PPC keyword research works best when you treat it as a step-by-step decision process, not just a way to collect more keywords.

The main goal is to find search terms that match the product, fit shopper intent, support the listing, and work within your ad cost and margin targets.

To keep it simple, this blog covered the key points that matter most:

• Start with keyword discovery. Use seed keywords, Amazon autocomplete, competitor research, reviews, Q&A, and search term reports to find real keyword opportunities.
• Evaluate keywords before scaling them. Check keyword relevance, search volume, purchase intent, competition, CPC, conversion potential, and profitability fit.
• Track the right metrics after launch. Use impressions, clicks, CTR, CPC, orders, conversion rate, attributed sales, ACoS, and ROAS to judge keyword quality.
• Use negative keywords to reduce wasted spend. Block irrelevant, weak-intent, or consistently unprofitable search terms to improve traffic quality.
• Avoid common keyword research mistakes. Do not chase search volume without relevance, ignore shopper intent, skip search term reports, or separate keyword targeting from listing relevance.
• Adjust keyword strategy by product stage. New products need discovery and validation. Mature products need scaling, refinement, and stronger efficiency control.
• Align keyword research with campaign structure. Discovery terms, exact-match terms, branded keywords, and competitor keywords should be separated based on their purpose.

The key takeaway is simple:

• Target keywords that are relevant
• Test keywords that show real potential
• Scale keywords that prove they can convert profitably

That is how Amazon PPC keyword research helps turn search terms into better traffic, better conversions, and stronger long-term campaign performance.
