An advertising executive takes over a Google Search ads campaign. On his Google Ads Recommendations page he notes that the campaign's optimization score is 40%. What does this score indicate?

The campaign could be improved by 60% if the listed recommendations are followed.
The campaign is 60% less optimal than other company campaigns.
The campaign is running 40% over budget.
The campaign is 40% optimized for the given keywords chosen by the previous campaign manager.

And this is the correct answer:

The campaign could be improved by 60% if the listed recommendations are followed.

Explanation:

If the optimization score of the firm's Google Search Ads campaign is 40%, it simply means that it can be improved by 60% in order to reach the full potential of the programme.

It does not mean that the campaign is 60% less optimal than others because the score only measures the firm's own campaign.

And it does not have any direct connection with the campaign's budget or keywords.
