On October 7, 2026, Google completed the rollout of text customization asset previews for AI Max for Search, enabling every advertiser to generate and review up to 10 AI-written headlines and descriptions in under 30 seconds, before enabling the feature in their campaigns. For ecommerce brands whose Search campaigns were automatically migrated to AI Max on September 1, this means you can now audit AI-generated copy before it reaches a single customer.
Before this update, activating AI Max's text customization was a commitment made without visibility. Google's AI generated headlines and descriptions from your landing page, but there was no way to preview what it would write before opting in. Now, any advertiser can see sample AI-generated assets pulled from their specific landing page in under 30 seconds and decide whether to activate text customization based on what Google's AI actually produces for their brand.
On September 1, 2026, Google automatically upgraded all Search campaigns that used campaign-level broad match or automatically created assets to AI Max. That migration moved a large number of ecommerce advertisers into AI Max without them making a deliberate choice. The lack of a preview option was the single most cited concern from advertisers reluctant to let AI generate their copy. The asset preview feature directly addresses that objection, giving every advertiser a path to evaluate AI Max text customization with full visibility before committing.

The preview is accessible inside the Asset optimization section when creating a new Search campaign or editing an existing one. After reaching the text customization setting, advertisers request a preview. Google pulls from the campaign's associated landing page, existing keywords, and current ad copy to generate sample headlines and descriptions within 30 seconds. Advertisers see up to 10 candidate assets and can use those samples to evaluate brand voice, product accuracy, and message consistency before deciding whether to enable text customization. The preview takes roughly two minutes per campaign to complete and requires no budget spend or live traffic exposure.
Strong AI Max previews produce headlines that reference specific product names, key differentiators, or price points pulled directly from the landing page. Weak previews produce category-level copy that could apply to any brand in the space. For ecommerce brands, the quality of the preview correlates directly with the specificity of the landing page content. Product pages with a strong headline, clear benefit bullets, and specific price or offer callouts above the fold produce significantly better AI-generated headlines than pages with minimal copy or generic category language. If the preview shows weak copy, the fix is improving the landing page, not disabling AI Max entirely.

No. Text customization is an optional component of AI Max. If your preview shows that the AI-generated copy does not meet your standards, you can keep text customization disabled while still using other AI Max features like broader query matching and URL expansion.
The preview generates up to 10 AI-written headlines and descriptions within approximately 30 seconds, based on your campaign's landing page, existing keywords, and current ad copy.
The AI Max preview reflects the quality of your current landing page content. Thin or outdated pages tend to produce generic AI copy. Improving your product page headline, benefit bullets, and above-the-fold specificity before running a preview will produce more relevant and brand-accurate AI-generated assets.
Not all campaigns. Google auto-migrated Search campaigns that had campaign-level broad match enabled or that used automatically created assets. Campaigns using only exact match or phrase match without auto-created assets were not automatically upgraded. Check each campaign's settings individually to confirm its AI Max status.
