Frequently Asked Questions

Should I Block Siteliner?

Consider blocking Siteliner only if you do not want your pages included in SEO databases. It does not influence how search engines rank you, and blocking it will not hide backlinks to your site because those are discovered on the linking sites. For context, 7% of the top websites we track currently have robots.txt rules for Siteliner.


Does Siteliner Follow Robots.txt Rules?

Yes. Siteliner is expected to follow robots.txt rules, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Siteliner respects it.


Does Siteliner Access Private Content?

No. Siteliner can reach only public pages, and authentication prevents it from accessing private content.


How Can I Tell if Siteliner Is Visiting My Website?

Agent Analytics tracks Siteliner visits in real time. You can also check your server logs for requests whose user-agent string contains "Siteliner". Look for comprehensive site crawls that follow internal links. Because Siteliner does not publish a verification method, any client can claim its identity and a log match is only a clue.


Why Is Siteliner Visiting My Website?

Your domain appears in the ranking, backlink, or competitor data maintained by Siteliner's operator. A customer may be tracking your site, one of your competitors, or a backlink that connects another site to yours.
