Authors Panic Over Amazon’s Hidden Algorithm Shift

About this video

Dale L. Roberts condenses Joe Solari’s long research article ‘The Hidden Rules of Amazon’ — Solari, he says, manages millions in royalties for top-earning authors — into nine insights meant to explain why many authors have seen steady sales, page reads and rankings suddenly stall. The central claim is that Amazon now judges books on a rolling 180-day average rather than recent spikes, so consistency beats launch velocity: a book selling steadily month after month trains the system better than one big launch day. Since 2016, he says, Amazon has also tracked consumption — whether buyers actually open, read and finish a book — so free-promotion downloads that go unread can hurt rather than help, while Kindle Unlimited page reads signal engagement. Visibility is split across search, ranking and recommendation engines, with recommendations driving almost one-third of page views and built from readers-also-bought patterns, which rewards connected series and a single-genre focus. Cold, low-converting traffic can weaken a book’s data for up to 180 days, so he advises warming readers up off Amazon and using attribution links. Advertising is presented as effectively mandatory — he says over 80% of first-page search results are sponsored, up to 100% on mobile — but its real purpose is seeding data, not instant profit. Finally, he says Amazon builds a behavioral profile around each pen name, and cites Solari’s research that lasting success typically takes 3 to 5 years and around 10 to 15 books, with emotional connection and craft ultimately driving the signals.

Key takeaways

• Per Joe Solari’s research as summarized here, Amazon evaluates books on a rolling 180-day average, so steady sales outweigh launch-day spikes
• Consumption matters: Amazon tracks whether readers open, read and finish books, so unread free-promo downloads can work against a title
• Recommendations drive almost one-third of page views and are built on also-bought patterns — connected series and one clear genre strengthen them
• Cold traffic that clicks without buying can damage a book’s data for up to 180 days; warm audiences up first and use attribution links
• He cites Solari’s finding that durable success usually takes 3 to 5 years and about 10 to 15 books of consistent publishing
