What is Netcraft?
About
Netcraft is a web crawler that conducts comprehensive internet surveys, analyzing web server technologies and infrastructure across millions of websites to provide market intelligence. You can see how often Netcraft visits your website by setting up Dark Visitors agent analytics.
Expected Behavior
The behavior of intelligence gatherers depends on the goals of their clients. For example, a client might be interested in brand sentiment, in which case the agent would crawl related social media or blog posts at a more frequent rate than unrelated websites.

Should I Block Netcraft?
Probably not, especially if you benefit from an intelligence gathering service yourself. However, you might choose to block them if you're concerned about things like server resource usage.
How Do I Block Netcraft?
You can block Netcraft 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.
