Frequently Asked Questions
Should I Block Google Image Proxy?
Usually not. Blocking Google Image Proxy 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 Image Proxy.
Does Google Image Proxy Follow Robots.txt Rules?
No. Google Image Proxy 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.
Does Google Image Proxy Access Private Content?
No. Google Image Proxy 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 Tell if Google Image Proxy Is Visiting My Website?
Agent Analytics tracks Google Image Proxy visits in real time. You can also check your server logs for requests whose user-agent string contains "Google Image Proxy". Look for a page and its preview assets being requested without follow-up navigation. Because Google Image Proxy does not publish a verification method, any client can claim its identity and a log match is only a clue.
Why Is Google Image Proxy Visiting My Website?
Someone shared a link to your page. Google Image Proxy 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.
