Frequently Asked Questions

For context, 9% of the top websites we track currently have robots.txt rules for webzio-extended.


Does webzio-extended Follow Robots.txt Rules?

Yes. webzio-extended 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 webzio-extended respects it.


Does webzio-extended Access Private Content?

Not through legitimate access. webzio-extended primarily targets public content, but some training-data scrapers also attempt to collect gated or paywalled pages. If content loads without authentication, assume it can be collected.


Why Is webzio-extended Visiting My Website?

Your content matched the criteria Webz.io set for a training dataset. webzio-extended typically discovers pages through external links, sitemaps, and seed lists rather than because someone selected your site individually.


How Can I Tell if webzio-extended Is Visiting My Website?

Agent Analytics tracks webzio-extended 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 "webzio-extended". Look for high page counts, short gaps between requests, and deep traversal through linked content. Because webzio-extended does not publish a verification method, any client can claim its identity and a log match is only a clue.
