Final URL Expansion

What Is Final URL Expansion?

Final URL Expansion can significantly expand your campaign reach, but carries risks: Google may redirect users to pages you didn’t intend as landing pages. In Performance Max, the feature is active by default and should be controlled with URL exclusions. The right balance between Google’s automation and your control over user experience is critical for campaign performance.

Final URL Expansion is a feature within AI Max for Search and Performance Max where Google dynamically changes the final destination URL of your ad. Instead of sending every user to your defined landing page, the AI automatically selects the page on your website best suited to the specific search query. Google crawls your website and decides in real time which URL offers the highest conversion probability.

The feature can improve performance if your website has many relevant landing pages. An online store with hundreds of product pages benefits from users landing directly on the matching product page. It becomes problematic when Google directs users to irrelevant pages like legal notices, career pages, or outdated content. That’s why a clean URL exclusion list is essential.

To control Final URL Expansion, use page feeds to explicitly tell Google which URLs are eligible as destination pages. Exclude all non-sales-relevant pages via URL rules. Monitor in the landing pages report which pages Google actually directs users to. Without this control, you risk burning ad budget on pages without conversion potential.
