Ad Strength

Ad Strength is Google's rating, from Poor through Average and Good to Excellent, of how closely your responsive ad follows its own best-practice recommendations.

You finish building a Responsive Search Ad and a little meter appears telling you the ad is "Average," with a checklist nudging you to add more headlines, make them more distinct, or include your keywords. That meter is Ad Strength. It reads your ad against Google's recipe for what a well-built responsive ad should contain, things like enough unique headlines, enough descriptions, and keyword coverage, and gives you a one-word verdict plus tips to raise it.

Used well, it is a helpful sanity check. If you are sitting on "Poor" because you wrote three headlines that all say the same thing, the rating is pointing at a real weakness, and fixing it usually does make the ad better. It stops you shipping a lazy ad and reminds you to give the system the variety it needs.

But here is what it is not. Ad Strength measures how well you followed Google's guidance, not how the ad actually performs. It does not feed your Ad Rank, your Quality Score, or your ability to win auctions. A "Good" ad can quietly beat an "Excellent" one on the numbers that pay your bills, clicks, conversions, and cost per result. So read it as a checklist hint while you are building, then judge the finished ad on its real performance data. Never gut a proven winner just to chase a higher label, because the label is not the scoreboard.

Let Ad Strength shape the draft, but let the conversions decide the winner.
