About AI Max experiments

AI Max for Search (or "AI Max") makes your Search ads better. It uses Google AI to reach more customers in real time. It has 2 main features: search term matching and asset optimization. An AI Max experiment acts as a test run. It lets you try these AI tools on your ads before you apply them to your whole campaign. Learn more About AI Max for Search campaigns .

AI Max experiments deliver faster results and reduce some of the common experimentation errors. It diverts traffic and budget within an existing campaign instead of creating a copy of the campaign to experiment on. This article shows how these tests work.

Benefits

Unlike custom experiments, AI Max experiments offer the following benefits:

• Faster results: By using a single campaign, you can likely get results and insights more quickly.
• Minimal setup errors: Updating both control and treatment arms in the same campaign prevents setup errors and sync issues.
• Shorter learning period: This approach is likely to have a reduced learning period, since the traffic remains in the same campaign.

How it works

Search feature experiments enable advertisers to easily test key Search ads features like Broad Match keywords and AI Max settings.

• Control: A % of your existing Search campaign with AI Max toggle turned off.
• Trial: The remaining % of your existing Search campaign with AI Max toggle on.

After completing an experiment, advertisers can evaluate performance and choose if they want to “apply the experiment”, which turns on the AI Max setting for the campaign.

Steps to implement

1. Go to Experiments within the Campaignsmenu.
2. Select the plus button, and select Campaign features and settings.
3. Select AI Max for Search campaigns.

The experiment, by default, activates both AI Max features, Search Term Matching and Asset Optimization, at the campaign level. However, you have the flexibility to disable Search Term Matching at the ad group level and disable Asset Optimization at the campaign level, if you prefer. Your chosen settings will only apply to the treatment arm of the experiment.

Similarly, you'll have the flexibility of using other features that are available with AI Max, like adding URL exclusions at the campaign level and URL inclusions at the ad group level.

Setup limitations

You cannot create an AI Max experiment through this flow if:

• The campaign has enabled Legacy features like text customization (formerly known as automatically created assets), brand inclusions and exclusions, ad group location inclusion
• The campaign targets Display network
• The campaign is a part of a Portfolio Bidding Strategy
• The campaign uses Shared Budgets
• The campaign uses Bidding exploration
• The campaign has any active experiments

These limitations, with the exception of "targeting Display Network," also apply to AI Max experiments you create using the Custom experiments flow.

Reporting

You can find Experiment results under the “Experiments” tab, with an expanded view of the “Experiment summary” page when you select the experiment campaign.

---

Applying the feature

You have a few different options of how to apply results:

• When creating the experiment, there's an option to “Apply your experiment changes if results are favorable”. You can select this during setup if you want the experiment to automatically apply if the results are favorable at the end of the experiment.
• After the experiment ends, you can select Applyfrom the Experiments table.
• After the experiment ends, you can enable AI Max from the Campaign settings page.

Differences between new AI Max experiments and AI Max experiments through Custom experiments

You can choose between the new AI Max experiments or a custom experiment. Custom experiments require you to copy your campaign. This creates a separate "trial" campaign and a "control" campaign. The new AI Max experiments keep everything in one place.
