How do I find reputable book promo sites?
- Book promo sites email deals to genre-segmented subscribers.
- Quality varies widely; some have tiny or fake audiences.
- Check subscriber numbers, genre fit, and past results.
- BookBub is the largest; many smaller sites exist.
- Test with a small spend before scaling up.
Find reputable book promo sites by vetting each one before paying: check whether they have a real, sizable audience in your genre, look for transparent subscriber numbers and honest reporting of typical results, and read author reviews of their performance. Favor sites with genre-segmented lists so your deal reaches the right readers. Start with one or two well-regarded options and a small spend, track the sales each drives, and reinvest only in the ones that perform. Avoid sites that promise vague "exposure" without audience data.
Chapter i·Why it matters
The book-promotion space is crowded with sites of wildly varying quality — some with large, engaged, genre-targeted audiences, others with tiny or padded lists that waste an author's budget. Knowing how to vet promo sites and test before committing protects authors from spending on promotions that do not sell books. Understanding what signals reputability — real subscriber numbers, genre fit, transparent results — helps authors build a promo strategy around the sites that actually reach readers, rather than chasing empty exposure.

Chapter iii·Example
Planning a promo push, an author shortlists promo sites that publish their subscriber counts and serve her genre. She runs a small-budget test on two, tracks the sales each drives, and finds one clearly outperforms. She reinvests in the winner and drops the other — building her promo strategy on real results, not marketing claims.
