A Google Ads account can look efficient at keyword level while spending money on searches the business would never choose deliberately. The reason is simple: a keyword is the targeting instruction in the account; a search term is what a person actually typed.

For US businesses, a search terms audit connects real queries to cost, lead quality and sales outcomes. It can reveal irrelevant demand and landing-page gaps, but aggressive negative keywords can also create damage.

This guide separates Google’s documented platform behavior from our recommendations so you can reduce waste without blocking valuable prospects.

What the search terms report actually shows

Google’s search terms report documentation says the report lists searches used by a significant number of people that triggered impressions and clicks. The Keyword column identifies which account keyword matched the search, while the Match type column describes how closely the query related to that keyword.

The report is not a complete transcript. Google omits some low-activity queries for privacy, and conversion lag can create differences between reports.

Google’s search terms insights group queries—including some that are not exposed individually—into intent-based categories and subcategories. That is platform evidence. Our recommendation is to use both views: the report for query-level decisions and insights for broader demand patterns.

1. Review business outcomes, not only clicks

Add columns for cost, clicks, conversions, conversion value and the keyword that matched. Then connect the report with CRM outcomes where possible. A low-cost form submission can still be a poor result if the enquiry is outside the service area, unqualified or never becomes a sales conversation.

Classify queries into practical groups:

  • Relevant and proven: aligned with the offer and producing qualified outcomes.
  • Relevant but unproven: commercially plausible but lacking enough data.
  • Research intent: useful for awareness but not necessarily ready to buy.
  • Wrong product, audience or location: clearly outside the business offer.
  • Ambiguous: cannot be judged from the words alone.
  • Brand or competitor: requires a separate strategic decision.

Do not label every non-converting query as waste. A high-consideration B2B service may need more time and multiple interactions before a deal appears in CRM. Our offline conversion tracking guide explains how to return qualified-lead or revenue signals to Google Ads.

2. Distinguish keywords from actual searches

Suppose a commercial cleaning company targets the broad-match keyword office cleaning service. It might receive relevant searches such as “nightly office cleaners near me,” research queries such as “office cleaning checklist,” and irrelevant searches such as “office cleaning jobs.”

The keyword is not automatically bad because one query failed. Review patterns across the keyword, ad group, location and conversion outcome. Recurring irrelevant intent may justify an exclusion; relevant queries with weak results may instead expose an offer or landing-page problem.

Google says broad match can reach related searches and works with additional contextual signals. Google also recommends pairing broad match with Smart Bidding. That is Google’s platform position, not a guarantee that broad match will suit every account. Our recommendation is to test it only with accurate conversion goals, sufficient controls and routine search-term review.

3. Choose the correct negative match type

Google supports negative broad, phrase and exact match for Search campaigns, but these exclusions do not behave exactly like positive keywords.

According to Google’s negative-keyword documentation:

  • negative broad blocks a search when it contains all negative-keyword terms, even in a different order;
  • negative phrase blocks searches containing the complete phrase in the same order; and
  • negative exact blocks only the specified query with no additional words.

Use the narrowest exclusion that addresses the problem. If a law firm does not offer free advice, a negative phrase for “free legal advice” may be safer than excluding free across the entire account, where it could block a valuable query such as “free consultation personal injury lawyer.”

Negative keywords do not automatically match every close variant. Google says advertisers may need to add synonyms and singular or plural versions, although casing and misspellings are handled automatically. This limitation makes periodic review necessary.

4. Audit close variants before blaming match type

All positive keyword match types are eligible for close variants, and Google says there is no opt-out. Its close-variant definition includes misspellings, singular or plural forms, abbreviations, reordered words, implied terms, synonyms and searches with the same intent, depending on match type.

Not every close variant is relevant. Review the query’s commercial meaning: similar language can represent a different service, customer type or purchase stage.

Avoid creating hundreds of reactive exclusions from one-day data. Group repeated problems by intent. A staffing company may need exclusions for job seekers, training and salary research; a home-services company may need DIY and parts-only exclusions. Shared lists can improve consistency, but account-level negatives should be reserved for terms that are unsuitable across every eligible campaign.

5. Protect valuable searches before adding exclusions

Before publishing a negative list, run three checks:

Conflict check

Confirm that a negative does not overlap with an active keyword or a profitable query theme. Google’s setup guidance warns that overlap can prevent an ad from showing.

Scope check

Decide whether the exclusion belongs at ad-group, campaign or account level. A term irrelevant to one service may be valuable to another.

Evidence check

Record why the term is being excluded: wrong service, unsupported geography, employment intent, informational-only intent or confirmed poor lead quality. “No conversion yet” is usually not enough by itself.

Log the negative, match type, scope, source query, date and reviewer so changes can be reversed if volume drops unexpectedly.

6. Use good queries to improve ads and landing pages

A search terms audit is not only a blocking exercise. Relevant queries can reveal how prospects describe the problem, which service modifiers matter and which objections the landing page should answer.

For example, repeated searches containing “same-day,” “for small business” or a specific city may justify a new ad-group structure or page section if the business genuinely offers that service. Do not copy awkward queries into ads merely to repeat keywords. Translate the intent into clear, truthful language.

7. Measure what changed

Record a baseline before adding negatives: spend, relevant-query share, qualified leads, cost per qualified lead and impression volume for protected themes. Review results after enough comparable data accumulates, allowing for conversion lag and seasonality.

Attribution remains a limitation. An exclusion may coincide with changes in bids, competitors, demand or the website. Do not claim that a negative list alone caused better revenue. Make smaller batches of changes so the account remains interpretable.

A practical weekly search terms workflow

First, review the highest-spend and highest-click queries. Second, inspect recurring irrelevant themes and verify CRM lead quality. Third, add only evidence-backed negatives at the correct scope and match type. Fourth, protect valuable queries and update ads or pages where intent is clear. Finally, document the change and monitor reach as well as efficiency.

The takeaway is straightforward: search-term control is not about blocking as much traffic as possible. It is about understanding real customer language, removing clearly unsuitable demand and giving valuable searches a better path to conversion.
