Note: Display Expansion is transitioning to a new channel prioritization model.
-
Previous setup: When enabled, Display Expansion automatically delivered ads on the Google Display Network using unspent budget at similar cost per conversion as Search and with a 50% budget allocation applied in the backend.
-
Updated options as of October 2026: You can now set priority tiers (High or Low) and assign an optional daily budget allocation percentage cap for channels, such as the Google Display Network.
-
What to expect starting in February 2027: Starting in February 2027, Search campaigns with Display Expansion will automatically transition to channel prioritization. Once this takes effect, the current spend allocation setup will go away, and you may see a shift in channel spending between Google Search, Search partners, and the Google Display Network. To keep your current configuration, you can set the Google Display Network to “Low priority” with a 50% daily budget allocation.

Display Expansion on Search campaigns can help you reach additional potential customers on the Google Display Network using your Search campaign settings.
How it works
You can enable and manage Display Expansion for your Search campaigns using Channel prioritization account-level default settings or campaign-level overrides in your Campaign Settings. You can also assign priority tiers and set an optional daily budget allocation percentage cap to control Display spend. The settings for your Search campaign will be observed in the Display Expansion wherever possible, including:
- Bidding and targeting, for example, contextual relevance.
- The overall campaign budget will be observed. You can control how your budget is distributed to Display using account-level defaults or campaign-level overrides, including setting Display to Low priority and applying an optional channel budget allocation percentage, which operates on a best-effort basis to limit daily spend on that channel.
- Cost per conversion on Display may vary depending on your chosen bidding strategy, priority settings, and custom budget allocation.
- Ads will be automatically created based on your Search ads, although you'll have the option to easily create image ads in the “Assets” section, which is under the “Campaigns” tab of your Google Ads account.
- It’s recommended to use Responsive Display Ads to expand your reach even further and help improve your performance.
Your ads can appear when people search for terms on Google Search and search partner sites that match your keywords, and they can also appear on relevant website pages and apps on the Google Display Network. Google Ads distributes budget to the Display Network based on your campaign's bidding strategy, assigned channel priorities, and any daily budget allocation configured in your account or campaign settings. Search campaigns that have spare search budgets and are opted into Display Expansion can deliver up to 15% more conversions at similar CPA to Search. You can expect to find an average of 14% more conversion value for Search, if your core Search campaign is using Maximize Conversion Value or Target ROAS.
Find the right audience
A Search Network campaign with Display Expansion increases your reach with no additional setup, and can help you find the right audience at the right place and the right time.
- Additional impressions and conversions: Search campaigns opted into Display Expansion show ads on the Display Network according to your bidding strategy, assigned channel priorities, and any daily budget allocations you set.
- Performance: Search campaigns opted into Display Expansion and that have spare Search budget can deliver up to 15% more conversions at similar CPA as the current campaign's CPA.
- Grow your potential audience: By adding the Display Network, your ads can appear on the Google Display Network, allowing you to reach potential customers who browse or research similar products on a collection of more than 3 million websites, videos, and apps.
- Be strategic with little extra work: Since the Display Expansion is fully automated, your ads will be optimized to target across the Display Network with no additional setup.
Use responsive ads to reach more people
To expand your reach even further and help improve your performance, create a responsive ad for your Search Network campaign with Display Expansion. Responsive ads are a convenient, all-in-one format that serve across the entire Display Network. Using the assets that you enter, including headlines, images, and your landing page responsive ads, they automatically adjust their size, appearance, and format to fit just about any available ad space. By creating one ad that fits almost any ad space on Display, a responsive ad can increase your reach and impact while also saving your time. If you’ve uploaded Google Ads image assets, from Search for example, Display Expansion may create responsive display ads automatically with no work required on your part.

Note: If you’ve been running Search Network campaigns and then expanding to Display, you may notice an increase in conversions and thus, an increase in daily spend. On average, your cost per conversion on the Display Network should be similar to that on the Search Network.
