What is it?
The AB Testing for Ads optimization is a data-driven tool that helps you compare ads with statistically significant data in the same ad group. It helps you find ads that meet your business goals or contribute to the success of your advertising campaign, pause underperforming ads and create new ones to continue testing.
How does it work?
The system analyzes and tabulates the ads for comparison under each ad group, filtering only the underperforming ads based on the selected criteria. The analysis takes into consideration data pulled in real-time from your Google Ads and Bing Ads account, and it can look up to 180 days of data.
The optimization makes the recommendations based on one of three parameters (CTR, Conversion Rate, and Conversion per Impression) and considers only ads with statistically significant data. This optimization support copying tracking template.
Why should I use it?
The optimization identifies the best and worst-performing ads in active ad groups (including image ads for display and expanded text ads for search), allowing the analysis of the suggestions by comparing clicks and conversions parameters side by side before pausing the lowest performance ads.
The system also recommends high performing headlines, description lines, and display URLs (from your best performing ads) to create new ads in the ad groups where you are pausing ads with a lower performance.
Select the campaigns or labels for which you want to see results. You can also see any labels that have been assigned to the ads in Google Ads.
- Date range:
Select the date range you want to take into consideration for the statistical analysis. By default, the system looks at the last 30 days.
Search, Display, or both. *If you want to only see data for Google Search (not Search Partners), write to us at email@example.com to enable the feature on your account.
- Turbo Mode:
The Turbo Mode lowers the traffic threshold required to show optimization suggestions and gives you access to a larger, less-refined data set. When you turn on the Turbo Mode in AB Testing, you'll see all active ad groups with all active ads with more than one impression in them.
These settings let you select the parameters you are going to use to find the ads.
- Test Required Confidence: This setting lets you choose the confidence level you need the system to be (mathematical accuracy) for the results. You can select one of the three available settings (90%, 95%, and 99%).
For example, when you choose 99% it means that the system is 99% sure of the results it shows. Usually, as the confidence percentage increases, the number of suggestions decreases. We recommend using a 95% confidence setting in most cases.
- Mobile Preferred: Select Yes to compare only mobile preferred ads, No if you want to exclude mobile preferred ads in the comparison, or any to include both mobile preferred and desktop ads.
- Consider Ads with Impression count at least: You can choose between 100, 500, and 1000 impressions.
- Number of ad groups to test: The maximum number of ad groups shown at a given time.
- Ad Type to Test: You can choose to see results for text, image, and dynamic ads. For text ads, you can choose to compare legacy text ads and expanded text ads with their own kind and against one another. When you select "image", ads make sure to change the network to display to see results.
- Find winner by: You can choose between CTR, Conversion Rate, and Conversion/Impression (Combination of CTR and Conversion Rate). We recommend using CTR because the purpose of the ad is to get the user to click and go to the site
Create New Ad
The AB Testing tool also has a function to create a new ad, located on the right side of the results. You can create an Expanded Text Ad, Call Only Ad, or Responsive Search Ad.
Here you can set Headline Part 1, Headline Part 2, Description, Final URL, Path 1, Path 2, Label (optional) Mobile Final URL (optional), with Top Suggestions for each section, and a preview of how it would look. When you are satisfied, just press the "Create Ad" button.
While creating a new ad, you'll see recommendations for top-performing headlines and description lines on the right. These are based on clickthrough rate and from other ads in the same campaign and they are automatically generated by the Ad Variations feature in Drafts & experiments section of the Google Ads UI.
While you can't edit or pause ad variations using the API, you can manage them via the UI screen mentioned in that article if, for example, you no longer want them showing or accruing cost in any given Google Ads account.
Note that any ExpandedTextAds created by ad variations will have their systemManagedEntitySource == AD_VARIATIONS. So you can filter on and/or identify such ads when working with the API.
