Book Club Chat founder Heather Caliendo started a website dedicated to book club questions, reviews, and book lists with no upfront costs by dedicating a lot of time to reading and writing high-quality content that attracts over 5,000 daily visitors and has made $4,000 per month in ad revenue alone by focusing on organic search, SEO, and Mediavine.

OrderOfBooks.com is a website that lists books in both publication and chronological order and generates six-figure revenue after starting off as a resource for the founder and his friends, serving as a valuable resource for book readers.

Two friends started an online book club that now has 570 members and generates £10,500 MRR, by addressing the problem of 'Tsundoku,' charging a monthly subscription fee for one non-fiction book, one inspiring meetup, and one custom cocktail, inspiring conversation and community.
