Google Ads Search Terms and Negative Keyword Audit

The search terms report shows the real searches that triggered Google Ads. It is one of the most useful places to find wasted spend, new keyword opportunities, landing page ideas and customer language.

A negative keyword audit should not become a weekly exercise in blocking every query that has not converted. The goal is to improve relevance without removing valuable future demand.

Understand search term versus keyword

A keyword is the targeting input added by the advertiser. A search term is the actual query entered by the customer.

One keyword can match many search terms depending on match type, bidding, campaign context and Google’s matching systems.

Review both columns together:

1. Search term
2. Keyword that matched
3. Match type
4. Campaign
5. Ad group
6. Spend
7. Clicks
8. Conversions
9. Conversion value
10. Landing page

This shows not only which query appeared, but why it entered the account structure.

Define the role of each campaign

A search term can be correct in one campaign and wrong in another.

Examples:

1. Brand terms belong in the brand campaign
2. Competitor terms may belong in a controlled competitor test
3. Category terms belong in nonbrand acquisition
4. Customer support terms should not consume new customer budget
5. Informational terms may belong in a content or upper-funnel strategy

Write the role of each campaign before adding negatives.

Use the brand versus nonbrand structure guide to keep acquisition reporting clear.

Use three decisions

Classify material search terms as keep, exclude or isolate.

Keep

Keep when the query:

1. Matches the product or service
2. Shows useful customer intent
3. Fits the landing page
4. Performs acceptably or deserves more data
5. Supports the campaign role

A kept term can remain under the current keyword or become a new keyword when more control is useful.

Exclude

Exclude when the query:

1. Refers to something the business does not sell
2. Has an unrelated meaning
3. Seeks free downloads, jobs or support outside the campaign goal
4. Is geographically irrelevant
5. Is misleading or impossible to fulfil
6. Has sustained spend above the planned threshold with no strategic value

Isolate

Isolate when the query is relevant but needs different treatment.

Reasons include:

1. Different landing page
2. Different product margin
3. Different customer intent
4. Different budget
5. Different ad copy
6. Different bid target
7. Competitor search
8. Strong query hidden inside a broad group

Isolation protects the query from being judged by the wrong campaign average.

Build a negative keyword taxonomy

Organize exclusions by reason.

Common groups include:

1. Jobs and careers
2. Free, printable or download intent
3. Education or definition-only intent
4. Customer support and login
5. Wholesale when the business is retail only
6. Unserved countries or cities
7. Unrelated product categories
8. Used, rental or repair intent when unavailable
9. Competitors excluded from normal nonbrand campaigns
10. Brand terms excluded from acquisition campaigns

A taxonomy makes negative lists easier to review and prevents random additions without context.

Understand negative match types

Negative keywords behave differently from positive keywords.

Google notes that negative keywords do not automatically match every close variant or same-meaning version. Singular, plural and synonym forms may need separate consideration.

Negative exact

Blocks the exact query in the specified order, with the normal rules for negative exact matching.

Use when one specific query is unwanted but related searches may still be valuable.

Negative phrase

Blocks searches containing the negative phrase in the same order.

Use when the phrase consistently represents unwanted intent.

Negative broad

Blocks searches containing all negative keyword terms, even when the order differs.

Use carefully because a broad negative can remove more demand than expected.

Always check whether the negative overlaps with valuable positive keywords or product names.

Start conservative

When reviewing a questionable term, ask:

1. Is it truly irrelevant?
2. Does it describe a customer problem the product solves?
3. Could a better landing page convert it?
4. Is conversion delay active?
5. Has it spent enough relative to target CPA?
6. Does it assist another conversion path?
7. Is the query part of a useful new theme?

Exclude obvious irrelevance quickly. Be more careful with relevant terms that simply have limited data.

Set spend thresholds

A non-converting query should not receive unlimited spend.

Create thresholds based on:

1. Target CPA
2. Break even CPA
3. Conversion rate
4. Buying cycle
5. Query intent
6. Product margin
7. Strategic importance

Example:

If operating CPA is $35, the team may flag relevant non-converting search terms near $35 for review and apply a stronger stop-loss near the break even limit.

The threshold is a decision trigger, not an automatic negative rule.

Separate brand negatives

Add brand negatives to nonbrand campaigns when the goal is to measure discovery separately.

Include:

1. Brand name
2. Domain name
3. Common misspellings
4. Founder name when relevant
5. Owned product names
6. Brand plus discount or review terms

Review Shopping and Performance Max reporting as well because branded demand may appear outside the Search structure.

Handle competitor terms separately

Competitor searches often have different economics and customer intent.

Do not mix them into normal category campaigns without a clear reason.

A competitor test should have:

1. Separate budget
2. Separate ad copy
3. Relevant landing page
4. Legal and brand review
5. Defined target CPA
6. Search term monitoring
7. Clear stop-loss

Do not make misleading comparisons or imply an affiliation that does not exist.

Find new winning keywords

The report is not only for negatives.

Promote strong queries when they show:

1. Clear purchase intent
2. Repeated conversions
3. Strong conversion value
4. A distinct customer need
5. Better language than the current keyword list
6. A need for a more relevant ad or page

A new exact or phrase keyword can give the team clearer reporting and copy alignment. Adding it does not guarantee it will receive all matching traffic, so continue reviewing the query set.

Improve ads and landing pages

Search terms reveal how customers describe their needs.

Use them to improve:

1. Headlines
2. Descriptions
3. Product titles
4. Collection names
5. Frequently asked questions
6. Comparison sections
7. Search filters
8. Product page benefit language

A relevant query with weak conversion may be a landing page problem rather than a targeting problem.

Review account-level negatives carefully

Account-level negatives can apply across eligible Search and Shopping inventory. They are useful for terms that are clearly irrelevant to the entire business.

Good account-level candidates:

1. Employment searches when no recruitment advertising exists
2. Completely unrelated meanings
3. Prohibited internal terms
4. Markets the business never serves

Avoid account-level negatives for terms that may be useful in another campaign, product category or future offer.

Audit process

Weekly review

1. Review recent high-spend terms
2. Review new irrelevant themes
3. Review converting terms worth isolating
4. Check brand leakage
5. Check competitor leakage
6. Add only supported negatives
7. Record the reason

Monthly review

1. Review negative keyword lists
2. Check whether lists are applied to the intended campaigns
3. Find conflicts with positive keywords
4. Review old exclusions after product changes
5. Compare search term themes with landing pages
6. Review account-level negatives
7. Review change history

Google recommends checking the date range and change history when a blocked term still appears in an older report. A negative added recently does not remove historical impressions.

Negative keyword log

Record:

1. Negative term
2. Match type
3. Level: ad group, campaign or account
4. Date added
5. Reason
6. Search term evidence
7. Owner
8. Review date

This protects the account from exclusions that no one understands later.

Common mistakes

Blocking after one click

Normal variation is treated as proof of weak intent.

Using broad negatives carelessly

Valuable queries disappear with the unwanted theme.

Forgetting singular and plural intent

Negative matching does not behave like positive close variants.

Adding brand negatives everywhere

Brand campaigns or Shopping inventory are accidentally restricted.

Ignoring winning search terms

The audit only cuts traffic and never improves the account.

Never reviewing old negatives

The product range changes but old exclusions remain.

Applying a list to the wrong campaigns

The list exists but is not active where expected, or blocks a campaign it should not affect.

Final audit checklist

1. Campaign roles are documented
2. Brand and nonbrand are separated
3. Search terms are classified as keep, exclude or isolate
4. Negative match types are intentional
5. Spend thresholds reflect product economics
6. Competitor terms have a separate decision
7. Account-level negatives are truly universal
8. Strong queries become keywords or page improvements
9. Lists are applied to the correct campaigns
10. Every material negative has a reason

Final principle

A good search terms audit improves both efficiency and customer understanding.

Remove obvious irrelevance, isolate valuable themes, promote strong queries and use customer language to improve ads and landing pages. The goal is not the smallest possible traffic pool. The goal is the most relevant profitable demand.
