Hidden Signals
Your keywords, categories, and description formatting send signals to Amazon's ranking system. Small structural mistakes compound quietly — and most authors never know they're there.
Does your book make it from the cloud to the coffee shop?
Every day, readers search Amazon for exactly what you wrote. Whether they find it depends entirely on signals most authors never think about.
THE REAL ISSUE
Most indie authors don't struggle because their books are bad.
They struggle because the algorithm can't read them clearly. Three structural gaps account for most of it.
Expensive Guesswork
Running ads without aligned metadata increases your cost-per-click and lowers conversion — even when the writing is strong. The ad isn't the problem. The signal underneath it is.
Too Much to Manage
You're already doing the work of an entire publishing team. Metadata architecture, category strategy, and ad copy frameworks shouldn't be another full-time job on top of writing.
FREE DIAGNOSTIC — INSTANT DOWNLOAD
Is your book invisible to Amazon's algorithm?
Most indie authors are losing discoverability on 6 or more of these 10 signals — and have no idea. Get the checklist. Find out where you stand before you spend another dollar on ads.
Keyword String Alignment
Are your 7 backend keywords structured as exact-match search strings, or are you wasting slots on single words?
Description Formatting
Does your Amazon description use formatting that makes readers stop and read — or is it a wall of text they scroll past?
BISAC Category Fit
Are you in the right categories to rank on the charts your readers actually browse?
Subtitle Discoverability Score
Does your subtitle contain a searchable keyword phrase — or is it just a tagline?
Cover Thumbnail Signal
Is your cover legible at 80px wide? Does it signal the right genre in under 2 seconds?

Your writing gets evaluated on its merits — not buried by formatting errors

ONGOING AUTHOR INFRASTRUCTURE
Stay aligned with Amazon's changing signals.
Amazon's ranking system isn't static. Categories shift. Keyword patterns change. Formats that worked six months ago stop converting. Most authors find out too late — when the ads stop working or the sales quietly drop. Sonexial Subscriptions give you ongoing oversight without agency retainers — so the structural pieces Amazon actually uses to rank your books stay aligned.

THE PROCESS
Your 15-hour headache. Solved in 48.
Three steps. No guesswork. Here's exactly what happens to your book data.
Intake
You fill out a structured 10-minute form: genre, subgenre, comp titles, target reader, current metadata, and ad history. This isn't a generic questionnaire — every field maps directly to a specific output in your kit. No intake form, no kit. The specificity is the point.
Analysis
Your intake data is run against current Amazon search volume benchmarks, genre-specific BISAC category maps, and competitor keyword density patterns. Brian then reviews every AI-generated output line by line — cutting anything that's technically correct but strategically weak, and rewriting anything that doesn't match your book's actual voice and market position.
Deploy
You receive a formatted document with copy-paste ready outputs: HTML-encoded Amazon description, keyword strings structured for exact-match indexing, BISAC codes with chart eligibility notes, and ad copy variants labeled by use case. Open KDP. Paste. Done.
