Whoever you hire to fix a weak keyword will ask you this early: "Which keyword is it, and what does Google rate it on expected click-through rate, ad relevance and landing page experience?" If you answer "some of my keywords have a bad score," the first stretch of work goes to finding out what you could have told them. If you can name the keyword, the ad and the page, the work starts on the first call. This guide works backward from that question.
Why that question comes first
Quality Score is a diagnostic Google shows per keyword, and you can't turn it like a dial. It summarizes three ratings, and each one has a different fix. Expected click-through rate points to the ad and the keyword match. Ad relevance points to how closely the ad text matches the search. Landing page experience points to the page people arrive on. Owners who treat them as one problem end up rewriting ads that were never the issue.
Find the keyword and read its ratings
In your Google Ads account, open the keywords view and add the Quality Score columns, including the three component statuses. Each will read below average, average or above average. For the keyword you care about, write down which of the three is below average. Your future hire needs that note more than anything else.
Match the weak rating to the likely fix
| Rating below average | What it usually means | What to try |
|---|---|---|
| Expected click-through rate | People see the ad and do not click | Rewrite the headline to echo the search words and state a clear benefit or offer |
| Ad relevance | The ad does not reflect what was searched | Split the keyword into a tighter group with its own ad copy |
| Landing page experience | The page does not match the promise or is hard to use | Send the click to a page about exactly that service, loading fast and readable on a phone |
Keep the cluster small and the groups tight
A common cause of weak ad relevance is one ad group holding many unrelated keywords, so a single ad cannot match them all. Give a struggling keyword and its close variants their own group, and write the ad for that group alone. Fewer keywords per group make the matching easier for both you and Google.
Check what the search terms really were
Open the search terms report for that keyword. If broad matching pulls in searches you did not intend, the click-through rate suffers and the relevance rating follows. Add negative keywords for the irrelevant ones, and consider a tighter match type for the keyword itself.
Keep expectations realistic about search size
The cluster around this topic is small: about 60 combined searches a month across 4 distinct queries. Most owners who land here are looking at one stubborn keyword, not a sprawling account, which is good news. A narrow problem can usually be fixed with a handful of careful edits, without an overhaul. It won't improve instantly, though, because ratings move as Google collects fresh impressions after your changes.
Change one thing, then wait
If you rewrite the ad, swap the page and reorganize the groups all at once, you will not know what worked. Change the part the weak rating points to, note the date, and give it time to gather impressions before judging. Keep a short log of what you changed and when, which makes any later handoff easier.
What to bring to a specialist
Hiring help is reasonable if the ratings stay low after a clean round of edits, if you cannot tell which page or ad group is involved, or if the account has grown beyond what you can track. Bring the keyword, its three ratings, the ad text, the landing page address and your change log. With those, a person can quote and plan accurately, and you can judge their advice against your own notes. If you only want a second opinion on the account, a review is a lighter step than ongoing management.
