How can the optimization score be used to help increase the effectiveness of a Google Search campaign?
Correct Answer
It can show how close a campaign is to being optimized to its full potential.
Why is this the correct answer?
The optimization score can be used to show how close a campaign is to being optimized to its full potential. Running from 0% to 100%, the score gives a clear snapshot of campaign health based on Google's best practice recommendations. A score below 100% indicates specific gaps — shown as actionable recommendations with their individual score impact — that the advertiser can address to improve performance. This makes it a practical tool for identifying and prioritising optimisation work.
Why are the other options incorrect?
It lets you compare ad text creative with other ads and find ways to make them more effective.
Optimization score does not compare ad creative performance against other advertisers' ads — competitive creative analysis requires separate tools like Auction Insights or Ad Preview.
It lets you compare the popularity of your website to others so you can know your market shar.
Optimization score does not measure website popularity or market share relative to competitors — it evaluates the campaign's own configuration against best practices.
It helps you determine a website’s network performance and find ways to optimize it.
Optimization score does not analyse website technical or network performance — it assesses campaign settings and configurations, not server-side or technical website metrics.
Real-World Example
A search campaign for an accounting firm scores 61%. The recommendations page shows adding target ROAS bidding (+15%), adding 3 new ad groups (+8%), and enabling Search partners (+4%) would bring the score to 88%. The account manager implements the bidding change first, sees a 23% improvement in conversion value, and uses the score as a running measure of campaign health.
