Frequently Asked Questions
What Traffic Patterns Should I Expect From ArenaUnfurlBot?
ArenaUnfurlBot usually makes a single request within seconds of a URL being shared, without crawling further. Traffic rises and falls with sharing activity, so a widely circulated link can produce a sharp burst of fetches.
Does ArenaUnfurlBot Follow Robots.txt Rules?
No. ArenaUnfurlBot is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Use Bad Bot Blocking to reject its requests, then use Agent Analytics to verify that they stop.
Is ArenaUnfurlBot Used for AI Model Training?
Not ordinarily. ArenaUnfurlBot is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking ArenaUnfurlBot Affect AI Search or Citations?
Not directly. ArenaUnfurlBot's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does ArenaUnfurlBot Access Private Content?
No. ArenaUnfurlBot has no credentials and should access only the public URL and assets needed for a preview. It does not continue through the rest of your site.
How Can I Verify a Request From ArenaUnfurlBot?
Agent Analytics tracks ArenaUnfurlBot visits in real time. You can also check your server logs for requests whose user-agent string contains "ArenaUnfurlBot". Look for a page and its preview assets being requested without follow-up navigation. Because ArenaUnfurlBot does not publish a verification method, any client can claim its identity and a log match is only a clue.
