What is AddThis?

About

AddThis crawls websites to collect metadata and content for social sharing optimization, gathering information needed to populate share buttons, content widgets, and social media previews. You can see how often AddThis 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 AddThis?

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 AddThis?

⚠️ 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 AddThis 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.
