Why Is Buttondown Visiting My Website?
Someone shared a link to your page. Buttondown 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.
Should I Block Buttondown?
Usually not. Blocking Buttondown 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, 7% of the top websites we track currently have robots.txt rules for Buttondown.

Frequently Asked Questions
What Traffic Patterns Should I Expect From Buttondown?
Buttondown 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 Buttondown Follow Robots.txt Rules?
No. Buttondown 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 Buttondown Used for AI Model Training?
Not ordinarily. Buttondown is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Buttondown Affect AI Search or Citations?
Not directly. Buttondown's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does Buttondown Access Private Content?
No. Buttondown 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 Buttondown?
Agent Analytics tracks Buttondown visits in real time. You can also check your server logs for requests whose user-agent string contains "Buttondown". Look for a page and its preview assets being requested without follow-up navigation. Because Buttondown does not publish a verification method, any client can claim its identity and a log match is only a clue.
How Is Buttondown Different From Other Buttondown Agents?
Buttondown operates separate agents for different purposes, so each agent should be evaluated and controlled independently.
