Frequently Asked Questions

Should I Block Bluesky Link Preview Service?

No. Bluesky Link Preview Service builds the link preview that appears when someone shares your page in a chat or social feed. Blocking it turns those shares into bare links with no title or image, which fewer people click. Its traffic normally follows sharing activity rather than a crawl schedule, so if it ever starts crawling at volume, rate limit it instead of blocking it. Almost none of the top websites we track have robots.txt rules for Bluesky Link Preview Service right now.

Does Bluesky Link Preview Service Respect Robots.txt?

No. Bluesky Link Preview Service is not expected to honor robots.txt, so a disallow rule only states your preference. Enforce the block with firewall or server rules, then confirm in Agent Analytics that its requests actually stop.

Does Bluesky Link Preview Service Access Private Content?

It cannot. Bluesky Link Preview Service loads only the exact URL someone shared, reads the title, description, and preview image, and leaves. It has no credentials and does not follow links to other pages.

Why Is Bluesky Link Preview Service Visiting My Website?

Someone shared a link to your page. Bluesky Link Preview Service fetched it once to build the preview card, and every new share can trigger another fetch, so spikes mean your content is spreading.

How Can I Tell if Bluesky Link Preview Service Is Visiting My Website?

Agent Analytics tracks Bluesky Link Preview Service visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "Bluesky Link Preview Service". Look for hits on single pages moments after someone shares a link, with no crawling afterward. Keep in mind that Bluesky Link Preview Service doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
