Google Ads search terms: find the clicks your business does not need
In Google Search campaigns, keywords and search terms have different roles. You choose keywords to bid on, but Google's matching system decides which actual searches trigger your ads. For Irish SME owners, learning to read the search terms report is one of the most direct ways to protect your advertising spend without sacrificing genuine sales opportunities.
Understanding the difference between keywords and search terms
The keywords in your account are targets you define. Search terms are the real queries people typed. Google Ads records these in the search terms report, which shows performance data for actual searches that triggered your ads. Without checking search terms, you cannot tell which searches your budget is funding.
Judging relevance before performance
Query wording hints at intent but does not guarantee it. A search for shelving installation training only matters if your business actually provides such training. Second-hand shelving queries may suit dealers in used goods, so do not dismiss them automatically as irrelevant. Someone researching advice might purchase later, so avoid claiming informational searches never convert. Always judge queries against your specific services and campaign objectives before excluding them.
Building negative keywords with precision
Negative keywords exclude your ads from specific searches. Google's system applies different match type rules for negatives than for positive keywords. Understanding these mechanics prevents expensive mistakes.
Negative exact match, written with square brackets, blocks only that precise query. For example, adding [phone cases] as a negative exact blocks "phone cases" but does not by itself exclude "buy phone cases" or "durable phone cases".
Negative phrase match, written with quotation marks, blocks any search containing that exact sequence in that exact order. Adding "phone cases" as a negative phrase blocks "buy phone cases", "phone cases online", and "where to buy phone cases" because all contain that ordered phrase. It would not block "cases for phones" because the word order differs.
Critically, negative keywords do not cover close variants the way positive keywords do. Check spelling and singular/plural variants separately.
Negative keyword scope determines reach; account-level exclusions affect multiple campaigns, so audit which campaigns will be impacted before applying. Some terms suit one product line yet harm another, making universal exclusions risky. Avoid automatically blocking competitor names or geographic terms without reviewing their actual performance in your account. Match the scope to your structure and review regularly as offerings evolve.
The risk of overblocking
Aggressive negative keyword strategies can backfire. Generic exclusions like "free" or "cheap" seem safe until you realise they would block "free delivery", "free consultation", or "cheap international shipping" queries from genuine buyers. Review the context in which problematic words appear before adding negatives.
"Hire" can indicate commercial intent. "Hire wedding marquee Cork" is a buyer query for an events company. "Hire event coordinator" might be either a jobseeker or someone seeking to contract services. The surrounding words matter more than any single term.
Working within privacy limitations
Google withholds some low-volume search queries for privacy reasons, so your search terms report is necessarily incomplete. Do not guess at hidden query contents. Build exclusions from visible queries combined with business relevance, and supplement with aggregate spend analysis and actual enquiry quality. See Google's reporting guidance.
Maintaining a practical change log
Ad hoc negative keyword additions create confusion. Establish a simple log recording each change: the term excluded, the reason for exclusion, the match type used, the scope applied (account, campaign, or ad group), the date added, and a scheduled review date. This discipline prevents the accumulation of conflicting or forgotten exclusions that silently suppress valid traffic.
Review outcomes matter. If you add negatives and enquiry volume drops sharply while quality improves modestly, you may have been too aggressive. The log enables this assessment.
Frequently asked questions
Why can I not see all search terms in my report?
Google aggregates low-volume queries to protect user privacy. These appear as "other search terms".
Should I add a negative keyword after seeing one irrelevant click?
A clearly irrelevant query can justify immediate exclusion even after a single click. Ambiguous phrasing warrants closer investigation rather than automatic blocking. You need not wait for repeated wasted spend. Select appropriate negative match types, apply at suitable scope, and document your reasoning for future review and team alignment.
Protecting your investment
Search term review is foundational Google Ads hygiene. It simply demands regular attention to the gap between what you intended to buy and what you actually received.
