Frequently Asked Questions
Should I Block seo4ajax?
Consider blocking seo4ajax 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. Almost none of the top websites we track currently have robots.txt rules for seo4ajax.
Does seo4ajax Follow Robots.txt Rules?
Yes. seo4ajax is expected to follow robots.txt directives, 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 seo4ajax respects it.
Does seo4ajax Access Private Content?
No. seo4ajax can reach only public pages, and authentication prevents it from accessing private content.
Why Is seo4ajax Visiting My Website?
Your domain appears in the ranking, backlink, or competitor data maintained by seo4ajax's operator. A customer may be tracking your site, one of your competitors, or a backlink that connects another site to yours.
How Can I Tell if seo4ajax Is Visiting My Website?
Agent Analytics tracks seo4ajax visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "seo4ajax". Look for comprehensive site crawls that follow internal links. Because seo4ajax does not publish a verification method, any client can claim its identity and a log match is only a clue.
