What is AASA-Bot?

About

AASA-Bot is Apple's crawler that fetches Apple App Site Association files to support Universal Links functionality, allowing iOS apps to handle specific URL patterns. You can see how often AASA-Bot visits your website by setting up Dark Visitors agent analytics.

Expected Behavior

Fetchers visit websites on-demand. They're normally dispatched by apps to present metadata about a link (e.g. the title and thumbnail image) to a user.

Should I Block AASA-Bot?

Probably not. If you block a fetcher, it won't be able to fetch the metadata it needs to display a link preview. Fewer people will click on the link to your website without this.

How Do I Block AASA-Bot?

⚠️ Manual Robots.txt Edits Are Not Scalable
New agents are created every day. Instead, serve a continuously updating robots.txt that blocks new agents automatically.
Set Up Automatic Robots.txt

You can block AASA-Bot or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
