What is MJ12bot?

About

MJ12bot is Majestic's web crawler that maps link relationships between websites to build a comprehensive link graph for SEO analysis, providing backlink data and domain authority metrics without caching personal content. You can see how often MJ12bot visits your website by setting up Dark Visitors Agent Analytics.

Expected Behavior

SEO (Search Engine Optimization) crawlers do not adhere to a fixed visitation schedule for websites. The frequency of visits varies widely based on several factors, including the search keywords it ranks for, and how many other websites link to it.

How Do I Block MJ12bot?

You can block MJ12bot 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 SEO Crawlers?

⚠️ 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.
