Why Is Hatena Visiting My Website?
Someone shared a link to your page. Hatena 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 Hatena?
Usually not. Blocking Hatena 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 Hatena.

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