AI book finder with organic traffic and ad and affiliate income
WhatIsThatBook helps readers find a book when they remember its plot, a character, or a scene but cannot recall the title. The site also includes a genre finder, book recommendations, daily book puzzles, trivia, and supporting articles. In October 2026, PostHog recorded 23,790 visitors, 25,906 sessions, and 66,958 pageviews. Google Search Console reported 7,856 web-search clicks. Leading queries include 'help me find a book' and 'find a book title by plot'. The site earns from Journey by Mediavine ads and Amazon Associates. October ad revenue was $107.86, and the book's Amazon tracking ID recorded $45.39 in product commissions for the same month, for $153.25 in confirmed revenue before operating costs. Amazon bounties are excluded because they have not yet been split by website. Ad revenue was $125.87 in August and $126.04 in September. A paid membership is implemented at $5 per month or $50 per year, but it currently has no paying subscribers. There is no current direct sponsorship revenue. These features are opportunities for a buyer, not existing subscription income. The current owner reports very low hosting costs on Cloudflare and near-zero API expense through credits. A buyer should budget for their own API usage; the owner's credits are not included in the sale. Journey requires a new owner to reapply, and Amazon links must use the buyer's own approved account. The proposed sale includes the domain, application source code, seller-owned site content, and deployment configuration. Final asset scope and transition support will be agreed with the buyer.
Next step: <p>Current maintenance is about 2 hours per week. The code was built by the seller with AI assistance. I can provide 14 days of transition support after sale. The buyer needs their own API credentials and budget, Amazon Associates account, and Journey approval.</p>
