Targeting expansion uses Google intelligence to help you reach individuals who share interest profiles with your existing customers. By expanding your targeting, you can reach more potential customers (even in cookieless environments) who are likely to engage, click, or convert with your ads.
Advertisers can use targeting expansion to reach users with similar return on investment (ROI) based on contextual signals, allowing it to work even when the third-party cookie is missing entirely (e.g. on Safari ITP 2.0 traffic) or when it can’t be used for ad personalization (i.e. user did not provide consent).
How is targeting expansion different from similar audiences?
Targeting expansion is the overarching feature that expands your audiences. Within targeting expansion, you can expand on both first-party and Google audiences using the same slider.
The similar audience mechanism only applies to first-party audiences. Therefore only first-party audiences can have similar audiences.
Similar audiences are now part of the overarching targeting expansion feature. You can use targeting expansion to expand both first-party and Google audiences.
How this feature works
This feature uses manual targeting inputs in combination with Google machine learning to expand reach to customers with similar interest profiles who are likely to engage with your campaign.

Bulk editing line items
In addition to setting targeting expansion settings on individual line items, you can also adjust targeting expansion settings across multiple line items using bulk edit. Learn more
When editing multiple line items with different targeting expansion settings in bulk edit, Display & Video 360 automatically enables targeting expansion across all line items (if all line items meet the criteria mentioned above). Once enabled, you can still manually adjust the targeting expansion slider.
