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.

Half of your traffic probably comes from artificial agents, and there are more of them every day. Track their activity with agent analytics.

Should I Block Bing 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 Bing Preview?
You can block Bing 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.

Recommended Solution
