Frequently Asked Questions
What Traffic Patterns Should I Expect From SlackbotLinkExpanding?
SlackbotLinkExpanding 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 SlackbotLinkExpanding Follow Robots.txt Rules?
No. SlackbotLinkExpanding is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Is SlackbotLinkExpanding Used for AI Model Training?
Not ordinarily. SlackbotLinkExpanding is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking SlackbotLinkExpanding Affect AI Search or Citations?
Not directly. SlackbotLinkExpanding's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does SlackbotLinkExpanding Access Private Content?
No. SlackbotLinkExpanding 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 SlackbotLinkExpanding?
Agent Analytics tracks SlackbotLinkExpanding visits in real time. You can also check your server logs for requests whose user-agent string contains "SlackbotLinkExpanding". Look for a page and its preview assets being requested without follow-up navigation. Because SlackbotLinkExpanding does not publish a verification method, any client can claim its identity and a log match is only a clue.
