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

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