Optimization Score is Google's estimate of how well your account is set up to perform, shown as a percentage climbing toward 100 percent alongside a list of changes it wants you to make.
You open your Google Ads account and a number is staring at you: 74 percent, maybe 68 percent, in a color that is not quite green. Next to it sits a stack of suggestions, each promising a small bump if you apply it. It feels like a report card, and the pull to get that number up toward 100 is real, because a low score looks like you are doing something wrong and a high one looks like you have your house in order.
Here is what the number actually measures. Google looks at your settings, your recent stats, and the pile of recommendations it has queued for you, then estimates how close you are to the setup it thinks is ideal. Applying a recommendation raises the score. Dismissing one also raises it, because you have cleared it off the list. That is the tell: the score moves when you act on the suggestions, not when your cost per lead drops or your sales go up. So the suggestions lean a particular way, toward Google's defaults: more automation, broad match keywords, higher budgets, automated bidding. Some will help you. Some will pour spend into searches you never wanted.
Applying them in bulk is the trap. The apply-all button is right there, and it will fix your score in one click while changing a dozen things you never chose to change. Treat the score as a list of things worth a look, not a grade to chase. Read each recommendation on its own, ask whether it serves your goal, and dismiss the ones that do not without guilt.
A 100 percent score means your account looks like Google wants it to, not that it is making you money.
