About targeting expansion in Display campaigns

Targeting expansion is now available as optimized targeting for any new Display campaigns that you create. Like targeting expansion, optimized targeting looks at any audience segments you’ve added to your targeting and uses that as a starting point to find new and relevant audiences for the campaign. As an additional benefit, optimized targeting may look for audience segments that fall outside your selected audience segments if there’s an opportunity for better performance.

One of the most efficient ways to get great performance from Display campaigns is to expand your targeting reach automatically with the targeting expansion feature. This lets Google find more high-value traffic to help you drive more conversions efficiently. Targeting expansion offers better forecasting and control, making it easier for you to predict performance.

With the default setting, targeting expansion conservatively expands the reach of your Google Display ads to more relevant customers. As you maximize your settings, your reach will increase, giving you control over how broadly your ads are served.

Think of targeting expansion as a high-impact add-on that supplements the targeting you’ve already set up. This article explains how to use this setting to meet your campaign goals.

When to use targeting expansion

Targeting expansion works best for advertisers in any of the following situations:

  • Find more customers.
  • Identify the best targeting to reach your most likely customers.
  • Increase reach without increasing bids or cost per customer.

Targeting expansion results in new placements, so it's suitable for advertisers who don't have strict brand guidelines about where their ads appear. Keep in mind that you can still exclude placements from your ad group, campaign, or account. However, it's not recommended—excluding placements can decrease the performance of your targeting expansion.

How it works

Most Display campaigns begin with targeting expansion enabled and set to the least amount of expansion. To maximize both reach and performance, increase to the maximum expansion setting.

Increasing the rate of expansion increases your targeting to reach more potential customers. You’ll also notice weekly reach estimates based on your settings, which reflect the additional traffic inventory available and potential impressions.

Expansion currently works across most display targeting tactics. For example:

  • For contextual targeting, such as content keywords, expansion is based on the keywords you’re currently targeting. Google Ads will expand to additional, semantically relevant keywords or topics. So if your keyword is “pens,” the first stage of slider may extend to “felt-tip pens" and “ballpoint pens,” but the maximum reach stage might show your ads in contexts related to “whiteboard markers” or “mechanical pencils”—if there’s data to suggest that those keywords will lead to conversions.
  • For your data segment and similar segment targeting, expansion is based on your customer segments. If your data segment is for people visiting travel sites about Japan, targeting expansion may extend to show your ad to people visiting sites about Tokyo tourist destinations. If your similar segment is for people who have previously made a purchase on your site, targeting expansion may expand to include additional, highly relevant segments. With the setting maximized, targeting might go further based on your performance and relevant segments.


Targeting expansion is available for all standard Display ad groups. However, there is currently limited functionality on specific targeting types (such as demographics), in which targeting expansion isn't yet possible.

Smart Display campaigns

Smart Display campaigns use another type of automated targeting, combining contextual and audience-based targeting. They also automatically reaches people who've recently visited your site and are likely to convert. There’s no targeting expansion setting for Smart Display campaigns.
