If you have been running remarketing display ads over the last year, you might have noticed that impressions and clicks have significantly increased. We noticed this with one of our clients where the impressions and clicks on pure remarketing campaigns had significantly increased but our sessions, and therefore cookie pool, were relatively stable.
When investigating we found that Google was serving ads to an ‘automated audience’. This is a relatively new feature which didn’t get much press or public announcement on launch.
What is Google Display’s Automatic Targeting?
Google Display’s Automatic Targeting is a default option, under Audience Settings, that enables Google to expand your existing audience to users that have similar characteristics as those in your audience.
Google defines Automatic Targeting as ‘Automatic targeting expands your reach to additional users to help you generate more conversions at or around the same cost per customer with Google Display ads.’
Since this is a default setting, Google has full discretion to expand your audience and therefore spend to reach audiences you have not targeted.
How can you tell that your campaigns are using Automatic Targeting?
To find out whether your display remarketing campaigns are being served to automatic audiences, go to your audiences reports then look at the summary rows at the bottom.
You will see a row named Total: Display automatic targeting, you can then compare the audience performance to that of your existing remarketing audiences.
