Expected Behavior
ant-html 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.
How To Block ant-html With Robots.txt
Add this rule to your robots.txt file to request that ant-html not access your website, or use Automatic Robots.txt to request the same of all fetchers at once. You can customize which pages are blocked by swapping out / for a different path.

Frequently Asked Questions
Should I Block ant-html?
Usually not. Blocking ant-html 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. Almost none of the top websites we track currently have robots.txt rules for ant-html.
Does ant-html Follow Robots.txt Rules?
No. ant-html 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 ant-html Access Private Content?
No. ant-html 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 ant-html Is Visiting My Website?
Agent Analytics tracks ant-html visits in real time. You can also check your server logs for requests whose user-agent string contains "ant-html". Look for a page and its preview assets being requested without follow-up navigation. Because ant-html does not publish a verification method, any client can claim its identity and a log match is only a clue.
Why Is ant-html Visiting My Website?
Someone shared a link to your page. ant-html 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.
