To learn more about how Google provides recommendations for your ads in HubSpot, check out this video.
To review recommendations for your Google Ads campaigns:
In your HubSpot account, navigate to Marketing > Ads.
In the left sidebar menu, click Recommendations.
The total number of recommendations and Google optimization score for your connected Google Ads accounts are summarized at the top of the page. In the upper left, click the Accounts or Types dropdown menus to filter the recommendations shown.
Below the recommendations summary, you can review each individual recommendation, which lists a description of how and why you should optimize the associated ad campaign, ad group, or budget.
Under the affected ad campaign or ad group, you can automatically address the recommendation by clicking the associated action:
Add keyword: create a new keyword for the ad group to broaden the search queries you're targeting, or duplicate an existing keyword with a different match type.
Increase budget: increases your ad campaign's budget to ensure your bids are competitive for your configured keywords.
Move unused budget: increases the budget of your underfunded ad campaigns to ensure their ads are shown more often.
