Google Ads Optimization Score: Ignore It (Mostly)

Your Google rep emails you: your optimization score is 68%, here are eleven recommendations, let's get you to 100%. It sounds like a diagnostic. It reads like a report card. It is neither.

Optimization score is a queue-clearing metric. It goes up when the recommendations list gets shorter. It does not know what a booked job is worth to you, and it will happily suggest changes that broaden your keywords, spread your spend across Google's partner network, and swap your bid strategy for one that optimizes to a number you never set.

Here is what the score is actually measuring, which recommendations to dismiss without reading twice, and the setting that lets Google edit your account without asking you first.

What is the Google Ads optimization score actually measuring?

Google defines optimization score as “an estimate of how well your Google Ads account is set to perform,” scored from 0-100%, where 100% means the account “can perform at its full potential” (Google Ads Help). It is an estimate of *setup*, not a measure of *results*.

The score is calculated in real time from your account settings, your stats, the estimated impact of every recommendation currently available to you, and your recent recommendations history. Every recommendation carries a score uplift, which Google says can run anywhere from under 0.1% to 100%.

Two things it is not. It is not Quality Score — Google states plainly that optimization score is not used by your Quality Score, and the two answer different questions. And it is not a ranking factor in the auction. If you want the metric that actually moves your cost per click, read our breakdown of Google Ads Quality Score instead.

It also only covers active Search, Display, Video Action, App, Performance Max, Demand Gen, and Shopping campaigns. Pause a campaign and Google keeps scoring it for a while anyway: 7 days at the account level, and 7-90 days at the campaign level, because recommendations are trained on a 7-90 day data window.

Why does dismissing a recommendation also raise your score?

Because Google says so, in writing: “Your account can reach an optimization score of 100% by applying or dismissing all recommendations.” That single sentence, from Google's own help page, is the whole argument in one line.

Sit with it. If accepting a recommendation and rejecting it both move the number to the same place, the number is not measuring whether the recommendation was good for your business. It is measuring whether you looked at it and made a decision.

That means a 100% score is achievable in about twenty minutes by an intern who dismisses everything, and it means a 62% score can belong to an account printing money. The score is a to-do list completion rate wearing a performance metric's clothing.

One catch worth knowing: Google says a dismissed recommendation can reappear after a period if it becomes relevant again. Dismissing is not permanent. Put a recurring 20-minute slot on the calendar rather than treating the list as a one-time cleanup.

Which recommendations are auto-applied without your approval?

None — unless “Automatically apply recommendations” is switched on in your account, at which point Google applies a selected set of them on a daily basis without asking you again. Most owners who inherit an account from a previous agency have never checked whether that switch is on.

Google publishes the exact list of what can be auto-applied, grouped into ads and assets, bidding, keywords and targeting, and measurement (Google Ads Help). These are the ones a lead-gen account should care about, because they change what your ads match and how they bid:

• Add broad match keywords — auto-appliable. Broad versions of your existing keywords get added to Smart Bidding campaigns.
• Add keywords and Add keywords (Smart bidding) — auto-appliable. New keywords land in your ad groups.
• Expand your reach with Google search partners — auto-appliable. Your Search ads start serving on partner sites and YouTube.
• Use Display expansion and Use targeting expansion — auto-appliable. Search budget leaks onto the Display Network.
• Bid more efficiently with Maximize clicks / Maximize conversions / Target CPA / Target ROAS — auto-appliable. Your bid strategy is swapped.
• Adjust your CPA targets and Adjust your ROAS targets — auto-appliable. Your targets are moved for you.
• Add dynamic search ads — auto-appliable. Headlines get generated from your website content.

Credit where it is due: Google states that auto-apply will not raise your budget — “budget raising isn't included in this iteration of auto-apply recommendations.” Budget-raise suggestions still appear in the Recommendations tab and still come from your rep, but they need a human click. And as of January 26, 2026, “Add responsive search ads” was removed from the auto-apply settings page entirely.

Auto-apply only works at the account level, not per campaign. So it is all-or-nothing across every campaign you run — including the one you built carefully around exact-match emergency terms.

How do you turn auto-apply off, and where is that setting?

Go to Campaigns > Recommendations, and look at the top bar of the Recommendations section — that is where auto-apply is turned on and off. Google's docs describe it as a set of controls where you select which recommendations apply automatically, either as bundles (“Maintain your ads” and “Grow your business”) or individually by category.

Do this in one sitting, on every account you own:

• Open Campaigns > Recommendations at the account level (auto-apply does not exist at campaign level).
• Find the auto-apply controls in the top bar; check the Manage tab to see everything you are currently opted into.
• Uncheck every keyword, targeting, and bidding recommendation. Those are the ones that change what you match and how you bid.
• Open the History tab — Google's docs say it shows a summary of recently applied recommendations. That is your evidence of what already shipped.
• Turn on email alerts for account changes so the next “quick win” lands in your inbox, not just in a log.

If a current or former agency turned auto-apply on and never told you, that is the tell. The client owns the ad account, and nobody should be enabling silent daily edits to it without a written sign-off. It is one of the first things we check in a free Google Ads audit.

Which recommendations should a lead-gen business always dismiss?

Roughly the ones that expand reach, and roughly none of the ones that fix something broken. A plumber who wants emergency calls and a dental practice that wants implant consults have the same problem: more traffic is not the goal, more qualified traffic is. Most recommendations optimize for volume inside a target, not for lead quality.

The honest verdict: the single worst one for a service business is Bid more efficiently with Maximize clicks, because it silently retargets the whole account at a metric that has nothing to do with revenue. Broad match is a close second, but at least broad match can be contained with negatives. For how to pick a bid strategy on purpose, see our guide to bid strategy automation, and for the campaign type Google pushes hardest, whether Performance Max is right for service businesses.

Now the fair part. Some recommendations are genuinely worth applying, and they are almost all in the “Repairs” and “Measurement” groups: fix disapproved ads, fix your ad destinations, remove conflicting negative keywords that are blocking your own keywords from serving, set up conversion tracking, set up enhanced conversions. Those fix broken plumbing. Apply them.

One to read carefully rather than reflexively apply: Remove non-serving keywords, which Google recommends when keywords have had no traffic for a year or more. Tidy, harmless, and completely irrelevant to profit.

What should you do when your Google rep pushes a 'quick win'?

Ask for the recommendation to be shown to you as a proposed change, and then make the decision yourself. Google's docs describe “proposed changes” as optimizations recommended by your Google Ads account representative, which surface on the Recommendations page with an “Apply all” button (Google Ads Help). That button is the trap. It bundles good and bad together.

Three questions that end most rep calls fast:

• “What is my current cost per booked job, and what will it be after this change?” If they only have cost per conversion, they cannot answer.
• “Which of these changes can I reverse in one click if it goes badly?” Bid strategy switches restart the learning period; keyword expansion leaves search-term residue.
• “Will you put in writing that this raises my lead quality, not just my volume?” They will not.

Google reps are not villains. But note what the score they are steering you toward actually measures: whether the recommendation queue is empty, not whether your ads made money. Their incentives are structurally not your incentives, and a 100% optimization score is worth more to them than it is to you. Nobody should be guaranteeing you a result from any of it — not them, and not us. If an agency ever offers you a ranking or performance guarantee, walk.

How do you check whether Google has already edited your account?

Two places, and it takes about ten minutes. Google's documentation points to the History tab on the Recommendations page for a summary of recently applied recommendations, and to the Change History page to view or update the individual recommendations that were applied.

Set change history to the last 90 days, then look for the fingerprints of automation rather than a person: keywords appearing in batches, a bid strategy changing on a day nobody logged in, campaign settings edited outside business hours, targeting or network settings flipping on.

Then reconcile the dates against your lead volume. If broad match keywords were auto-added six weeks ago and your cost per booked job climbed 30% starting five weeks ago, you have your cause — and it was never a bad economy or a bad market.

A sane policy, once you have cleaned up: auto-apply off; recommendations reviewed once a month for 20 minutes; repairs and measurement recommendations applied; keyword, targeting, and bidding recommendations dismissed unless there is a specific reason to accept one; optimization score ignored as a KPI and reported to nobody. If your account is not set up to survive that policy, it is not set up for lead gen. Our paid ads service is built on exactly this: no lock-in, no guarantees, no silent edits, and a 90-day kill switch if a channel is not producing qualified leads.
