Should I Block SiteCheck-sitecrawl?
Only if you want your own pages and outbound links out of those tools. SiteCheck-sitecrawl collects the ranking and backlink data behind SEO tools, likely including ones you or your agency use, and it does not change how search engines rank you. Blocking it will not hide your backlink profile either, because backlinks are discovered on the sites that link to you. Almost none of the top websites we track have robots.txt rules for SiteCheck-sitecrawl right now.
Does SiteCheck-sitecrawl Respect Robots.txt?
Yes. SiteCheck-sitecrawl is expected to honor robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms SiteCheck-sitecrawl actually honors it.
Does SiteCheck-sitecrawl Access Private Content?
Login walls stop it. SiteCheck-sitecrawl analyzes public pages for rankings, links, and site structure.
