What is Google Web Preview?

About

Google Web Preview is a fetcher operated by Google. If you think this is incorrect or can provide additional detail about its purpose, please contact us. You can see how often Google Web Preview 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 Google Web Preview?

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 Google Web Preview?

You can block Google Web Preview 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.

How Do I Block All Fetchers?
Serve a continuously updating robots.txt that blocks new fetchers automatically.

⚠️ Manual Robots.txt Editing Is Not Scalable

New agents are created every day. We recommend setting up Dark Visitors Automatic Robots.txt if you want to block all agents of this type.
