The percentage at the top of your account looks like a grade, so it is tempting to chase 100%. The Google Ads optimization score is a useful signal, but it is only an estimate of account setup, and your results tell a fuller story. This guide explains how the score works, which recommendations deserve a yes and how to dismiss the rest without guilt.

What the Google Ads Optimization Score Measures
Google’s help page on optimization score describes it as an estimate of how well your account is set up to perform. It runs from 0% to 100% and appears at campaign, account and manager account level.
The score updates in real time. It draws on your account statistics, settings and status, the estimated impact of available recommendations and your recent recommendation history. Applying or dismissing a recommendation changes it, and so can settings changes or wider trends in advertising.
Which Campaigns Count
Only active campaigns are scored, and only certain types. Google lists Search, Display, Video Action, App, Performance Max, Demand Gen and Shopping. A paused campaign does not count.
The Score Follows Your Goal
The score aims at a goal such as conversions, conversion value, impression share or clicks. Google usually infers that goal from your bid strategy. A status icon tells you how it was chosen.
- Green checkmark. Google understands your bid strategy.
- Yellow question mark. The focus is based on a recommendation.
- Red minus. The focus defaulted to conversions, and setting a new bid strategy can fix it.
If the focus does not match your real aim, the recommendations will pull in the wrong direction. Read our guide to Google Ads bidding strategies to pick one that fits your goal before you act on the score.
How to Decide What to Apply
Each recommendation shows a score uplift, and Google says it can range from under 0.1% to 100%. A big uplift is not a reason to apply something. Ask three questions first.
- Does it match your business goal? A recommendation to raise a budget helps only if more volume is what you want.
- Do you understand the change? Read what will be altered before you press Apply.
- Can you measure it? Note the date, then compare results a few weeks later.
Recommendations Often Worth Applying
- Fixing broken conversion tracking or missing conversion setup.
- Adding extra assets such as sitelinks or callouts that fit your offer.
- Improving ad text variety, which our guide to ad strength explains.
- Repairing disapproved ads or limited campaigns.
Recommendations to Review Carefully
- Budget increases when your cost per conversion is already above target.
- Broader keyword suggestions that may bring irrelevant searches.
- Bid strategy changes that would alter how a stable campaign behaves.
- Automatically applied changes, which you should switch off unless you trust them.
Apply one change at a time where you can. That way you know which edit moved the numbers.
How to Apply or Dismiss
To apply, open the Recommendations page, select View on a recommendation and choose Apply. You can use Apply all within one recommendation type, but check the list first. To dismiss, use the X in the corner of the card or the three-dot menu and Dismiss all. Google notes that dismissed recommendations can come back later if they become relevant again.
A Practical Review Routine
A short, regular routine works better than an occasional clean-up. Once a week or fortnight, open the Recommendations page and sort the list by uplift. Read each item and sort it into one of three piles: apply now, test later or dismiss.
For items you apply, write down what changed and when. For items you dismiss, think about why. If the same recommendation keeps returning and you keep rejecting it, that tells you something about your strategy and may be worth a note for your team.
Watch for patterns across campaigns too. If many campaigns show the same open item, such as missing assets, one fix can lift several scores at once. If one campaign sits far below the others, start there.
Do You Need 100%?
No. Google says you can reach 100% by applying or dismissing every recommendation, so a perfect score only means the list is clear. Uplifts can add up to more than 100 in total, because applying some recommendations makes others unnecessary.
Optimization score is also separate from Quality Score. Quality Score compares ad quality with other advertisers, while the optimization score gives a broader view of account health. Use the score as one input in a regular review, alongside a proper Google Ads audit.
Many recommendations involve bidding, so it helps to know the difference between target CPA and target ROAS before you apply them.
Frequently Asked Questions
Is a low optimization score bad?
Not by itself. A low score means there are open recommendations. Some may be irrelevant to your goals, so review them before you worry.
Does the score affect my ad rankings?
No. Google says it is not used in Quality Score, and it is a guide for you, not a ranking input.
Should I use auto-apply?
Only for changes you fully understand. Most advertisers do better reviewing each recommendation by hand.
Final Thoughts
Treat the Google Ads optimization score as a to-do list you are free to edit. Apply what supports your goal, dismiss what does not and judge success by conversions, not by the percentage.
