Google Ads the other day introduced a new feature in their console to suggest to you the columns they think are important for you to see in your dashboard. Google calls this "recommended columns."
Google will suggest columns to you based on your campaign and account settings. Google said as an example, if you start using bid automation, we will start recommending the ‘Bid Strategy Type’ column to your Campaign table. With this launch, Bid Strategy Type will also stop being a required column in your Campaign reports, which will free up some horizontal space for you to see more of the statistics columns.
You can identify a recommended column by the blue underline in the column name.
These recommendations are turned on by default for all advertisers. You can turn off recommendations for individual columns or all columns. These settings are specific to the user in the account.
