What is YahooCacheSystem?

About

YahooCacheSystem is a web caching component that stores website content snapshots as part of Yahoo's search infrastructure, working alongside Yahoo Slurp crawler to improve search result delivery. You can see how often YahooCacheSystem visits your website by setting up Dark Visitors agent analytics.

Expected Behavior

Search engine crawlers do not adhere to a fixed visitation schedule for websites. The frequency of visits varies widely based on several factors, including popularity, the rate at which its content is updated, and the website's overall trustworthiness. Websites with fresh, high-quality content tend to be crawled more frequently, while less active or less reputable sites may be visited less often.

Should I Block YahooCacheSystem?

Probably not. Search engine crawlers power search engines, which are a useful way for users to discover your website. In fact, blocking search engine crawlers could severely reduce your traffic.

How Do I Block YahooCacheSystem?

⚠️ 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 YahooCacheSystem 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.
