Common Questions

Frequently asked questions

What is sell-through rate for a book series? +
Sell-through is the percentage of readers who buy the next book after finishing the previous one. A healthy sell-through is 50–70% from book 1 to book 2. It typically drops for each subsequent book but stabilizes in longer series.
How do I increase my series sell-through? +
End each book with a compelling hook for the next, include a preview chapter of the next book, and make sure your covers are series-branded. Pricing book 1 lower or free can drive higher overall series earnings through readthrough.
Should I calculate series income per reader or per book? +
Per reader is more useful for advertising decisions. If you know your average revenue per new reader (book 1 + readthrough), you know the maximum you can spend to acquire that reader profitably.
How many books should be in my series before I advertise? +
Most authors recommend at least 3 books before heavy advertising, so readers who love book 1 have more to immediately buy, increasing your revenue per reader and justifying higher ad spend.
