01Separate the work you want, the keyword, and the search
Start by writing down the services, areas, and customers you want, plus what you don't. Build keywords from that list. Then treat the search terms report as evidence of what people typed. A search that matched isn't automatically a good customer.
02Pick a match type as a reach decision
Exact match gives the most control, phrase match allows searches that include your keyword's meaning, and broad match reaches related searches. Google makes broad match the default and recommends it with Smart Bidding—bid strategies that use Google's AI to set a bid for each auction based on likely conversions. Choose based on your tracking quality, budget, and time to review.
03Expect meaning-based matching
Close variants include misspellings, plurals, synonyms, paraphrases, and searches with the same intent. Quotation marks or brackets don't restrict ads to one exact phrase. If a campaign has AI Max for Search turned on, Google can also match searches beyond your keywords and send people to other pages on your site (final URL expansion). Check the search terms report either way.
04Review search terms against real leads
On a set schedule, look at each search term's keyword, match type, cost, landing page, and conversions. Compare it with what happened to the leads it produced. Label searches as good fit, unclear, wrong service, wrong area, job seeker, existing customer, or another label you agree on.
05Add negatives at the narrowest level that works
Add a negative keyword only when the full search clearly shows work you don't want. Choose whether it applies to one campaign, a shared list, or the whole account. Negatives don't cover close variants, so add plurals and synonyms separately where needed.
06Keep a record you can undo
For each keyword or negative change, note the searches you saw, the date range, cost, lead results, the decision, and who approved it. Recheck after changes to services, areas, landing pages, or bidding. Some searches point to a landing-page fix rather than an exclusion.
