Frequently Asked Questions
What Traffic Patterns Should I Expect From Arquivo-web-crawler?
Arquivo-web-crawler periodically fetches complete pages rather than checking metadata alone. Visit frequency typically rises with your site's popularity and update cadence.
Does Arquivo-web-crawler Follow Robots.txt Rules?
Arquivo-web-crawler 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 Arquivo-web-crawler respects it.
Is Arquivo-web-crawler Used for AI Model Training?
Not ordinarily. Arquivo-web-crawler is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Arquivo-web-crawler Affect AI Search or Citations?
Not directly. Arquivo-web-crawler's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does Arquivo-web-crawler Access Private Content?
No. Arquivo-web-crawler 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 Arquivo-web-crawler?
Agent Analytics tracks Arquivo-web-crawler visits in real time. You can also check your server logs for requests whose user-agent string contains "Arquivo-web-crawler". Look for a page and its embedded assets being fetched again after a long interval. Because Arquivo-web-crawler does not publish a verification method, any client can claim its identity and a log match is only a clue.
