Top Books Websites Using reCAPTCHA

reCAPTCHA is Google's bot-detection and anti-abuse service.

Site Stats Database tracks 4,133 websites that are both reCAPTCHA and Books, each enriched with traffic, authority, and the full detected tech stack.

They tend to have lower authority than the typical website: their median Ahrefs Domain Rating is 24, lower than the 28 median across all sites Site Stats Database tracks.

Traffic estimates, keywords, and authority come from DataForSEO; Domain Rating comes from Ahrefs' public endpoint; and the topic, market, and technology detections come from Site Stats Database's own crawler.
