Quick answer
- Most documented: Amazon's KDP report menu, which names a dashboard, orders, pages read, promotions, pre-orders, month-to-date, prior months' royalties, a royalties estimator and payments.
- Most useful for a serial: Ream, whose help pages describe Member Analytics and a Story Pulse view with chapter retention and heat maps.
- Fastest: Apple Books, whose authors pages describe next-day sales reports and customised dashboards.
- Monthly only: Google Play Books and Kobo Writing Life, both of which document reporting that arrives with the payment cycle.
- Nothing documented: Substack, Ko-fi, Payhip, Tapas, Wattpad and GoodNovel publish no analytics description in the pages we read.
A writer's dashboard is the one part of a platform nobody outside can photograph, and it is also the part most reviews describe anyway. This page does not. We hold no account on any of these services and have seen no writer's view of any of them, so everything below is drawn from help articles, terms clauses and feature lists, which is the rule across this section for writers.
That limit is worth keeping in mind as you read, because a feature list is marketing and a help article is documentation. Where a platform names a report and says what it contains, the entry below is firm. Where a pricing page simply lists a phrase like member analytics, the entry is exactly as thin as the source.
What the documentation promises
| Platform | What its own pages describe | How firm the source is |
|---|---|---|
| Amazon KDP | A report menu listing Dashboard, Orders, KENP, Promotions, Pre-Order, Month-to-Date, Prior Months' Royalties, Royalties Estimator and Payment reports | Help navigation plus a dedicated help page for the pages-read report |
| Kindle+ through KDP Select | The KENP report, which shows you Kindle+ reading and listening activity by customers | A dedicated help page |
| Apple Books | Sales and Trends in iTunes Connect, next-day sales reports and customised dashboards | The authors Measure page |
| Google Play Books | Earnings reports, which the help page says are generated on a monthly basis.Sales and preview reports are recorded elsewhere without a page we could cite | A help page for earnings; the rest not confirmed |
| Kobo Writing Life | Sales reporting that accompanies each monthly payment | A terms clause; depth not confirmed |
| Barnes & Noble Press | A Sales Reporting dashboard with a Payments area showing payments by ID, and a full Payments by Date report | The royalty and payment terms page; sales depth not confirmed |
| Draft2Digital | Online sales reports, and store-by-store estimated royalties based on the list price you set | The FAQ and a terms clause; depth not confirmed |
| Patreon | Member analytics and insights | A pricing page feature list, which is all there is |
| Ream | Member Analytics on the Members page and Story Pulse on the Stories page, including chapter retention and heat maps | A help article on its analytics tools |
| Medium | A Partner Program dashboard with payout history and a rollover balance | The payouts help article |
| Literotica | Story Stats, listed alongside reader feedback, followers and series | The publishing guidelines; depth not confirmed |
| Dreame | A writer dashboard exists in the help centre menu; its contents were not readable | A menu entry only |
| Substack, Ko-fi, Payhip, Tapas, Wattpad, GoodNovel, Archive of Our Own | No analytics description found | An absence in the pages we read, not a statement that none exists |
| Webnovel | Behind the Inkstone login, so unconfirmed | The portal redirects to a sign-in |
The stores report money, with one exception
Store reporting is built around sales and royalties, which makes sense when the product is a purchase. The exception is the Kindle+ pool, where there is no purchase to report, so Amazon reports reading instead: the KENP report covers Kindle Edition Normalized Pages, the same unit the fund is divided by. That is the only report in this section that tells a writer how much of a book was actually read, and it exists because the payment model made it necessary rather than because anyone asked for it. How the fund works is on the Kindle+ page.
Speed varies more than depth. Apple's authors pages describe next-day sales reports, which is the fastest figure documented anywhere here. Google and Kobo both document reporting on a monthly cycle, tied to the payment run, so a writer there learns about a month's sales roughly when the money arrives. Draft2Digital sits in between with a useful extra: because it distributes to many stores, it shows estimated royalties store by store against the price you set, which is the nearest thing in this section to a comparison tool. None of those stores documents a reader-level figure at all.
Reader-level analytics, where they exist
Two of the direct-to-reader platforms document something a store cannot. Ream's help article on its analytics tools describes Member Analytics on the Members page and Story Pulse on the Stories page, with chapter retention and heat maps, which for a serial is the number that matters: not how many started the story but where they stopped. Patreon's pricing page lists member analytics and insights among its features, and that phrase is the whole of the documentation, so what it shows is not something this page can describe. Medium documents its payout history and rollover balance rather than readership, which fits a programme that pays on engagement without publishing the rate, as set out in how these platforms pay.
Discovery is documented far less than sales
No platform in this section publishes a ranking formula, and most publish nothing about placement at all. Three publish something worth knowing. GoodNovel's help centre describes Gem rankings for signed books, based on the total Gems a book receives over a daily or monthly period, with a separate ranking for books signed within the month. Apple's authors home page states that it takes no payments for preferential store placement, which is a negative fact but a useful one. Ream documents a discovery system of its own, with mature stories behind a reader opt-in.
For an erotica writer the more important documentation is about invisibility rather than ranking. Amazon's metadata guidelines say flagged titles will not surface in general product searches. Substack's guidelines say explicit content may be hidden or removed from its discovery features. Tapas tells creators it cannot promote or host independent series containing mature material. Those three sentences matter more than any dashboard, and they are collected on where erotica is banned.
Three questions worth asking before you rely on a report
First, what unit does it count? A sales report and a pages-read report answer different questions, and only one of them tells you whether anyone finished the book. Second, how often does it update, and is that before or after the payment? Monthly reporting tied to a payment cycle is a record rather than a signal you can act on. Third, does the platform document the report at all, or only name it? Half the entries in the table above rest on a single phrase in a feature list, and a phrase is not a promise.
Where the documentation is silent, this page stays silent too. The honest position on Substack, Ko-fi, Payhip, Tapas, Wattpad and GoodNovel is that their own pages told us nothing about what a writer is shown, and the right place to find out is the platform rather than a review of it. The costs attached to each of these accounts are on what the platforms charge, and the routes themselves on our list of platforms for writers.
FAQ
Which publishing platform gives writers the most reporting?
On published documentation, Amazon KDP, whose help navigation names nine reports including the pages-read report that Kindle+ earnings are based on. That is a count of documented reports, not a judgement about usefulness.
What is a KENP report?
Amazon's report of Kindle Edition Normalized Pages, which its help page says shows Kindle+ reading and listening activity by customers. It exists because Kindle+ pays from a monthly fund by pages read rather than by sale.
Can I see who read my erotica?
No platform in this section documents anything that identifies a reader. The closest documented figures are Ream's chapter retention and heat maps, which describe behaviour across a story, and Patreon's member analytics, which its pricing page names without describing.
Does Substack show writers their stats?
There are stats and earnings pages inside the product, but no Substack help article describing them was recorded, so this page states nothing about what they contain.
Do any of these platforms explain how stories get ranked?
Only GoodNovel, whose help centre says a signed book's Gem ranking rests on the total Gems it receives over a daily or monthly period. Everywhere else, no ranking formula is documented in the pages we read.
