Frequently Asked Questions
What Traffic Patterns Should I Expect From ia_archiver?
ia_archiver periodically fetches complete pages rather than checking metadata alone. Visit frequency typically rises with your site's popularity and update cadence.
Does ia_archiver Follow Robots.txt Rules?
ia_archiver is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether ia_archiver respects it.
Is ia_archiver Used for AI Model Training?
Not ordinarily. ia_archiver is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking ia_archiver Affect AI Search or Citations?
Not directly. ia_archiver's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does ia_archiver Access Private Content?
No. ia_archiver archives only what an anonymous visitor can see. Anything public at crawl time may remain available in its archive long after you remove it from your site.
How Can I Verify a Request From ia_archiver?
Agent Analytics tracks ia_archiver visits in real time. You can also check your server logs for requests whose user-agent string contains "ia_archiver". Look for a page and its embedded assets being fetched again after a long interval. Because ia_archiver does not publish a verification method, any client can claim its identity and a log match is only a clue.
