SeriesLens — series read-through for indie authors

Does a series keep its readers? Rank, est. sales, KU income, indie vs publisher and read-through on Amazon and in KDP Reports.

SeriesLens is a research tool for authors who write in series and publish in Kindle Unlimited. Most book research tools are built for low-content and single titles. SeriesLens answers the questions a series author actually has before starting a new series or writing the next book: • Does this series keep its readers from book 1 to book 2 and beyond? • Roughly how much does this book earn, and how much of it comes from KU page reads? • Is this shelf full of indie authors or traditional publishers? • How fast do the leaders release? ON A BOOK PAGE • Kindle Store rank turned into an estimated daily units range (sales + KU borrows) • Kindle Unlimited yes/no, page count, publication date, ratings, indie or publisher • "Book X of N" and a one-click series read-through: rank and ratings of every book, book 1 → 2 percentage and a plain verdict • Estimated monthly income split into sales and KU page reads • Release pace of the series (median days between books) ON SEARCH RESULTS • A summary of the page: share in KU, share in a series, share of book 1s, median ratings, sponsored results • A strip on each result (KU, Book X of N, stars, ratings, price) and a "Rank, sales & read-through" button for rank, est. sales, income and read-through • Optional: load rank and sales for the top 3 results automatically (off by default) • "Analyze top 10": one click reads the top 10 organic results and shows the niche at a glance: median rank, sales and income, share of income from KU, share in KU, share of indie authors, median pages and price, and how many came out in the last 6 months YOUR OWN SERIES (KDP REPORTS) • Open KDP Reports and click "SeriesLens: your series" to see read-through from your real KU page reads, box sets included. It works at any sales rank, where public data is too thin. • The same click saves your real royalties of the last 30 days per title, so on your own book pages SeriesLens shows your actual Kindle sales and KU income instead of an estimate. HONEST NUMBERS • Estimates are shown as ranges, with the reason when confidence is low. For slow-selling series SeriesLens shows the numbers without a verdict, or averages the rank over the days you check the series. PRIVATE BY DESIGN • Everything is calculated in your browser. No account, no analytics, nothing sent to us. • Amazon pages are read only when you click a button (or, if you turn it on, for the top 3 search results), a few pages at a time, with pauses. Free, with no daily limit on checks. Works on amazon.com, amazon.co.uk, amazon.ca and amazon.com.au. SeriesLens is an independent tool and is not affiliated with Amazon.
