Read-through tracker

Read-through, tracked month by month

Every series calculation rests on one number: how many readers of book 1 go on to book 2 and beyond. It changes with new releases, covers and prices. The tracker shows it as a trend and tells you when it drops.

Read-through over time: to book 2 and book to book after, by month, with reads by book — Three months of sample KDP reports.

How it works

1
Upload a KDP report
One month's royalties report. Pick the books in the series and their order.
2
Save the month
Read-through to book 2 and after, plus reads for every book, go into your history.
3
Keep bids honest
Get an alert when read-through drops, and update your settings in one click.

Checked against your ads too

The same KDP report also checks the ads analysis. If your read-through settings credit ad readers with more later-book reads than KDP paid for in total, the check says so and offers the read-through from the report instead.

Check against KDP: book 1 sales, page reads and later-book reads, ads compared with KDP, all passing

Questions

How is read-through calculated?

Reads per book are sales plus full Kindle Unlimited reads (pages read divided by the book's KENP page count). Read-through to book 2 is book 2 reads divided by book 1 reads; after that it's pooled across the later books.

Why does read-through matter for ads?

It decides what a new reader of book 1 is worth, and so how much you can pay for a click. If read-through drops and your settings don't change, bids keep paying for readers who no longer continue.

Which KDP report do I use?

A royalties report for one month from KDP Reports, or the older Sales Dashboard export. Save one per month to build the trend.

What's saved?

Per-book sales, page reads, page counts and the read-through figures for each period. Never the file.
