Ads Boost — Know which adverts actually sell books | BookBooster
Ads Boost

Know which adverts actually sell books.

Your ad spend sits in Meta and Amazon Ads. Your earnings sit in your KDP reports. Ads Boost puts them together, so you can finally see which adverts make money — and which quietly don't.

Currently running every day across our own publishing imprints. Opening to authors shortly.

You can see what you spent. You can't see what it earned.

Meta tells you impressions, clicks and cost per click. Amazon tells you units sold and pages read. Neither one tells you whether the advert you ran on Tuesday paid for itself.

And if a reader buys book one, then goes on to read the rest of the series, the advert that started it gets none of the credit. For series authors, that's where most of the money is.

So most of us end up guessing. Pausing adverts that were working. Keeping adverts that weren't.

What Ads Boost shows you
Which adverts actually made money

Three steps. No spreadsheets.

1
Connect your ad accounts

One click, through each platform's own secure sign-in. We never ask for your password, and the connection is read-only.

2
Add your book earnings

Your KDP royalty reports go in, and Ads Boost matches every sale and page read back to the book that earned it.

3
See what each advert really made

Spend on one side, actual earnings on the other, series read-through included. Per advert, per book, per market.

Answers, not dashboards.

True profit per advert
What it earned against what it cost, not cost per click.
Series read-through counted
The books read after the one you advertised.
Plain-English verdicts
Scale this, leave it alone, reduce it, stop it — and why.
Spend ceilings
The point where putting in more money stops bringing more back.
Per-book and per-market detail
Including Kindle Unlimited page reads, which most tools ignore entirely.

Read-only. Always.

Ads Boost never creates, edits, pauses or spends anything on your behalf. It reads your advertising figures and shows you what they mean. Nothing is ever written back to Meta.

You connect your own account through Meta's secure sign-in, and you choose exactly which advertising accounts Ads Boost can see. You can disconnect at any time.

Your figures are yours. They're stored encrypted, they're never shared with other authors, and they're never sold.

Built by publishers

We built this because we needed it.

Ads Boost came out of Totally Entwined Group's own advertising. We were spending real money on Meta without being able to prove which adverts were working — so we built the thing that could tell us.

It runs on our own imprints every day. Now we're opening it to other authors and publishers.

Questions authors ask

Is it safe to connect my ad account?

Yes. You sign in through Meta directly — we never see or store your password — and the connection is read-only. Ads Boost can look at your advertising performance. It cannot spend, post, or change anything.

What exactly do you read?

Your advertising performance: amount spent, impressions, clicks, and how your campaigns, ad sets and adverts are organised. Nothing else. No audiences, no creative assets, no personal information about anyone who saw your ads.

Do I need to be technical?

No. If you can run a Meta advert and download a KDP report, you can use Ads Boost. The answers come in plain English.

What about Kindle Unlimited?

Page reads are counted properly. For a lot of authors that's the majority of the earnings, and leaving it out makes advertising look far less profitable than it really is.

When can I get it?
