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

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