You set up your campaigns. You choose your keywords carefully. You trust Google to match your ads to the right searches. Then you open the search terms report and realize a third of your budget went to queries that have nothing to do with your business.

This is not a rare scenario. It is the daily reality for most Google Ads advertisers in 2026. As Google continues to expand match types, push broad match as the default, and hide a growing percentage of search query data, the gap between what you bid on and what you actually pay for keeps widening. The search terms report is your primary line of defense. This guide walks through how to use it effectively, how to build a negative keyword strategy around it, and how to maintain control of your ad spend even as visibility shrinks.

What the Search Terms Report Actually Shows You

The search terms report lives inside Google Ads under Insights and Reports. It displays the actual queries that triggered your ads, alongside metrics like impressions, clicks, cost, and conversions.

This is different from your keyword list. Your keywords are what you tell Google you want to target. Search terms are what users actually typed. The overlap between these two is often smaller than most advertisers expect.

For example, you might bid on the phrase match keyword "marketing budget software." The search terms report could show that your ad also appeared for queries like "free marketing budget template Excel," "marketing budget for small business," or "what is a marketing budget." Some of these are relevant. Others are not. And some are burning through your daily budget before your best prospects ever see your ad.

The Hidden Data Problem: What Google Is Not Showing You

Here is the uncomfortable truth: Google no longer shows you all the search terms that trigger your ads. Since 2020, Google has progressively reduced the visibility of search query data, citing privacy thresholds. Queries that do not meet a minimum volume of searches are grouped into a catch-all "other search terms" bucket.

The scale of hidden data

Industry analyses consistently show that around 40% of search term clicks and spend are now hidden from advertisers. For some keywords, especially those using broad match, the hidden percentage can climb above 80%. You are managing your budget with partial information.

You cannot manage what you cannot see. But you can build systems that account for this limitation. That is what separates well managed accounts from ones that bleed budget quietly.

How to Audit Your Search Terms Report: A Practical Process

Instead of checking search terms sporadically, build a repeatable process. Here is a framework that works whether you manage one account or twenty.

1

Set the right date range

Use a 30-day window to capture enough data for meaningful patterns. For new campaigns, wait at least two weeks before drawing conclusions. Looking at the last 7 days alone rarely gives you the full picture.

2

Sort by cost, not clicks

The most dangerous search terms are not the ones with the most clicks. They are the ones eating your budget without converting. Sort by cost descending and work your way down. Any search term that has spent a meaningful amount with zero conversions deserves immediate attention.

3

Categorize what you find

Sort each search term into three buckets: relevant and converting (leave alone, or add as exact match keyword), relevant but not converting (investigate the funnel before adding negatives), and irrelevant (add as negative keywords immediately).

4

Check for patterns

Individual search terms matter, but patterns matter more. If you see ten different queries that all include the word "free," that is a negative keyword. If you see multiple queries mentioning a competitor, that might be an opportunity or a waste depending on your strategy.

5

Account for the hidden 40%

Compare your overall campaign metrics against the metrics for visible search terms. If your visible search terms convert at 5% but your campaign average is 2%, the hidden queries are likely dragging performance down. When this gap is large, consider tightening match types or reducing budgets on affected campaigns.

Common patterns to look for

  • arrow_forwardJob-related queries (jobs, career, salary, hiring) from people searching for employment, not your product
  • arrow_forwardFree-seeking modifiers (free, template, download, DIY, cheap) if your product is paid
  • arrow_forwardCompetitor brand names you do not want to bid on
  • arrow_forwardGeographic terms outside your target service areas

Building a Negative Keyword Strategy That Actually Works

Adding negative keywords one at a time after reviewing search terms is reactive. A proper negative keyword strategy is proactive.

Start with a foundation list

Before you launch a campaign, build a negative keyword list based on your business. Every advertiser should have account-level negatives for job and career terms, free-seeking terms (if your product is not free), educational terms (unless targeting informational intent), competitor names you do not want to target, and unrelated industries that share terminology with yours.

Use shared negative keyword lists

Google Ads lets you create shared negative keyword lists that apply across multiple campaigns. Use these. Create separate lists by category: one for job-related terms, one for competitor exclusions, one for geographic exclusions. This keeps things organized and makes bulk updates manageable.

Schedule regular reviews

Search term review is not a one-time activity. For high-spend accounts (over $5,000 per month), review weekly. For smaller accounts, every two weeks is sufficient. Set a recurring calendar event. The key is consistency.

Document your decisions

Keep a simple log of negatives you add and why. This prevents you from second-guessing past decisions and helps if multiple people manage the account. It also creates a reference for when you set up new campaigns in the same vertical.

Match Types in 2026: What Has Changed

Understanding match types is essential context for search term management. Google has been steadily blurring the lines between match types for years, and in 2026, the differences are narrower than ever.

Exact match

No longer means exact. Google now shows your ads for queries it considers to have the same meaning as your keyword, including close variants, synonyms, and implied intent. An exact match keyword like [running shoes] can trigger for "sneakers for jogging."

Phrase match

Includes broad match modifier behavior since Google merged the two in 2021. It now captures queries that include the meaning of your keyword, in any order, with additional words.

Broad match

The most aggressive. Combined with Smart Bidding, Google will show your ads for queries that are semantically related to your keyword, even if they do not contain any of the words in your keyword. This is where most hidden spend occurs.

Google actively recommends broad match paired with Smart Bidding as the default strategy. For some accounts with strong conversion data and high budgets, this works. For smaller accounts or accounts with limited conversion history, it often results in wasted spend on irrelevant queries. The practical takeaway: regardless of which match type you use, the search terms report is your safety net.

When to Tighten and When to Trust the Algorithm

Not every irrelevant search term is a crisis. Google's Smart Bidding algorithms are designed to bid lower on queries they predict will not convert. In practice, this depends on data volume.

Tighten control when

Conversion volume is low (under 50 per month per campaign). Your CPA is above target and climbing. The hidden search term percentage is high. You are in a niche industry where semantic matching often fails.

Trust the algorithm more when

You have high conversion volume and stable CPA. Your Smart Bidding targets are being met consistently. You have been running broad match for 60 plus days with good data. Your product matches a wide range of intent.

Even when you trust the algorithm, never stop reviewing search terms entirely. The review cadence can slow down, but eliminating it creates blind spots that compound over time.
