Amazon Ads management & profit analytics for KDP authors

Stop watching your numbers.Start moving them.

Launch Sponsored Products campaigns, fix bids and placements in bulk, and kill the search terms that waste your budget — with every book's royalties, KENP, and break-even ACOS in the same window.

SelfPub Go — demo account
  • Campaign control — create, pause, re-bid, and clean up — without opening Amazon's console
  • Break-even per book — ACOS judged against what each book actually pays you, not a flat target
  • Your machine — royalty reports stay on your computer, not in our cloud

One loop. One window.

Running ads for books isn't a dashboard you glance at. It's a loop you run every week — and it shouldn't take three Amazon consoles and a spreadsheet.

Step 01 · Research

Start where readers start: the search box.

Type a keyword and see the books competing for it. Drop a competitor's ASIN and see the keywords it lives on. Volume, competition, and revenue estimates across eight Amazon markets — with an AI read on how crowded the niche really is.

  • Keyword search with volume and competition scores
  • Reverse-ASIN: the keyword list behind any book on Amazon
  • AI niche synthesis — saturation, weak covers, your angle in

Search volume for books is an estimate. We label it as one, and never invent a number.

How the research works
SelfPub Go — Niches & keywords — check a keyword
Step 02 · Launch

From keyword list to live campaign — without the console.

Pick the book, set the budget, choose auto or manual targeting, paste your keywords, add negatives, tune placements — then review one confirmation screen before anything goes live. Campaigns start paused, so nothing spends a cent until you press go.

  • Sponsored Products campaigns: auto or manual, broad / phrase / exact
  • Budget, default bid, bidding strategy, and placement adjustments — set at creation
  • Negative keywords from day one, not after the first wasted $50

Sponsored Brands: reporting and keyword bids today. Sponsored Brands campaign creation is on the roadmap.

Step 03 · Manage

The bulk edits Amazon's console never gave authors.

Every campaign, ad group, and keyword across all your marketplaces in one table. Select two hundred targets and move their bids in a single confirmed batch: set a value, multiply, or nudge by cents. Pause anything, anywhere. Tune Top-of-Search and Product-Pages percentages per campaign.

  • Bulk bid edits with a “was → will be” confirmation
  • Placement modifiers per campaign
  • Negatives at every level — plus reusable negative lists
  • Search-term inbox: make it a negative or promote it to exact, in two clicks

Step 04 · Optimize

The app proposes. You approve.

The bid co-pilot reads a campaign and suggests per-target moves — raise, trim, pause — with the data behind each one. Rules watch ACOS, spend, and zero-sale search terms between your sessions. Everything arrives as a proposal with an Apply button.

  • AI bid suggestions you apply in one confirmed batch
  • Rule-based recommendations, on schedule
  • Alerts when ACOS climbs past your threshold or a book slips into the red

Nothing runs unattended. No bid, budget, or negative reaches Amazon until you press Apply.

SelfPub Go — Search terms — not about the book
Step 05 · Profit

The only score that matters: what's left after the ads.

Import your KDP royalty reports and every ad number changes meaning. ACOS is scored against your actual royalty, not the cover price. Break-even shows per book. KENP pages count as money. Spend on one side, royalties on the other — plus the book's rank and reviews on the same row, so a price change or a new cover is something you can see rather than guess at.

  • A break-even ACOS per book, derived from its own royalty and price
  • Royalties, KENP, and ad spend joined per book and marketplace
  • Best Sellers Rank and review counts tracked with history — included on every plan
  • Eight marketplaces, totalled in one currency

Royalty reports are parsed and stored on your computer, encrypted — never uploaded to us.

From connected to corrected, on day one.

01

Connect Amazon

Authorize through Amazon's official Advertising API — the same OAuth screen every approved tool uses. You never hand over a password, and you can revoke access on Amazon's side at any time. Point the app at your KDP royalty export and it reads the rest.

02

Bring your campaigns in

Everything you're already running syncs into one table — campaigns, ad groups, keywords, negatives, across every marketplace you sell in. New campaigns launch straight from the app, so the console stops being where your week goes.

03

Run the loop

Fix bids before money burns, clean up the search terms draining budget, and judge every book by what it keeps rather than what it clicks. The app flags the next slip so it finds you, instead of the other way round.

Three steps, and the first one takes a minute.

Report-only, seller-priced — or the loop in one app.

Author dashboards report your money but don't touch campaigns. Ads platforms manage campaigns — for sellers, at seller prices. We keep an honest comparison of both families, where every statement about another product is a quote from that vendor's own pages, with the date we checked it.
