Ad variations makes it easy for you to test multiple versions of your ads by changing up the headline or description text, testing out different promotions, or highlighting the benefits of your products and services in various ways. Variations cannot be applied to final URLs. 

This article explains how to set up and edit an ad variation. If you would like to learn about the benefits of ad variations and when to use them, go to About ad variations.

Set up an ad variation

1. Sign in to your Google Ads account.
2. From the page menu on the left, click Drafts & experiments.
3. Click Ad variations.
4. Select the campaign you want to run ad variations for. You won’t be able to create multiple ad variations for the same campaign in the same date range.
5. To create a new ad variation, click the plus button .
6. You can establish rules in the Filter ads section:
   • Filter text ads by the headlines, description, and path fields.
7. Click Continue.
8. In the "Create variation" section, choose which type of variation you want to apply to your ads. Keep in mind that variations are case sensitive. Select an option from the list.
   • Find and replace. Finds text within the ad and replaces it with another. For example, you may want to test a variation of your ad by replacing “Book now” with “Call now.”
   • Update text. Modifies existing text in the ads.
   • Swap headlines. Swaps headlines 1 and 2.
9. Click Continue.
10. In the "Set variation details" section, give your ad variation a name.
11. Set the Start date and End date of when you want to run the ad variations. Your ad variation will automatically start running on the date you select. If that date is today it will start running soon. 
12. In Experiment split, enter the percentage of your campaign’s budget you wish to allocate for the ad variations. Your ad variation and original ads will be split by assigning cookies to users. That means users may see only one version of your ad, regardless of how many times they search. This can help ensure that other factors don’t impact your results, and may give you more accurate data.
