Expected Behavior
Twitterbot 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.

Frequently Asked Questions
Should I Block Twitterbot?
Usually not. Blocking Twitterbot may leave shared links without a title or image, making them less inviting to click. If it begins fetching at unexpected volume, try rate limiting before blocking it outright. For context, 4% of the top websites we track currently have robots.txt rules for Twitterbot.
Does Twitterbot Follow Robots.txt Rules?
No. Twitterbot 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.
Does Twitterbot Access Private Content?
No. Twitterbot 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 Tell if Twitterbot Is Visiting My Website?
Agent Analytics tracks Twitterbot visits in real time. You can also check your server logs for requests whose user-agent string contains "Twitterbot". Look for a page and its preview assets being requested without follow-up navigation. Because Twitterbot does not publish a verification method, any client can claim its identity and a log match is only a clue.
Why Is Twitterbot Visiting My Website?
Someone shared a link to your page. Twitterbot fetched it to build a preview card, and each new share may trigger another request. A spike often means your content is circulating more widely.
