What is Tumblr?

About

Tumblr is Automattic's link unfurling bot that fetches URL content to create rich Link Blocks in Tumblr posts, parsing responses to display titles, descriptions, and preview images for shared links. You can see how often Tumblr 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 Tumblr?

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 Tumblr?

⚠️ 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 Tumblr 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.
