Disallow: /Frequently Asked Questions
Should I Block Google-Read-Aloud?
No. Google-Read-Aloud 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. For comparison, 1% of the top websites we track already have robots.txt rules for Google-Read-Aloud.
Does Google-Read-Aloud Respect Robots.txt?
No. Google-Read-Aloud 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 Google-Read-Aloud Access Private Content?
It cannot. Google-Read-Aloud 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 Google-Read-Aloud Visiting My Website?
Someone shared a link to your page. Google-Read-Aloud 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 Google-Read-Aloud Is Visiting My Website?
Agent Analytics tracks Google-Read-Aloud 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 "Google-Read-Aloud". Look for hits on single pages moments after someone shares a link, with no crawling afterward. Keep in mind that Google-Read-Aloud 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.
