Frequently Asked Questions

How many sales does a BookBub Featured Deal generate?
Results vary widely by genre and price. A $0.99 Featured Deal in romance or thriller can drive 2,000–10,000 downloads in a day. Niche genres typically see 200–1,000. The higher the genre's subscriber count, the more downloads.
Is a BookBub Featured Deal worth the cost?
For most series authors, yes — especially for book 1. Even if the featured book barely breaks even, read-through sales on sequels often make the deal profitable overall. Use this calculator with your read-through rates to see your true ROI.
How do smaller promo sites compare to BookBub?
Smaller sites are much cheaper ($15–$60) and easier to get approved, but drive fewer downloads (50–500 typically). Stacking several smaller sites on the same day can approximate a mid-tier BookBub deal at a fraction of the cost.
What book price works best for promo sites?
$0.99 generates the most downloads but lowest royalty ($0.35 on Amazon). $1.99 is a sweet spot — still cheap enough to drive clicks but earns $0.70+ per sale. Free promotions work best for series book 1 where you recoup through read-through.
