001. Why you're losing

You're losing sales
to worse books.

You see it every day: books with worse covers than yours becoming bestsellers. Why? Because they feed Amazon's A9 algorithm the data signals it craves. Your book isn't bad. your data is silent.

Failure mode 01

Subjective
blindness.

You think your cover “pops.” Our computer-vision read proves it blends in with the competition at thumbnail scale.

Dx: scroll-stop contrast score 31/100
Failure mode 02

The keyword
gap.

You're ranking for words nobody searches for. We find the high-traffic terms you're missing, and the low-competition ones you can own.

Dx: 7 high-value terms unused
Failure mode 03

Conversion
leaks.

Shoppers click, but don't buy. We pinpoint the exact sentence in your blurb causing the drop-off, with neuro-linguistic scoring.

Data Doesn't Lie. Results Don't Either.

"I thought my cover was fine. The analysis flagged the title contrast as 'Poor'. I fixed it, and my CTR doubled overnight. You can't argue with the data."

— Marcus T., Sci-Fi Author

"The Keyword Gap detection found 3 major search terms I had completely ignored. This tool is smarter than any human consultant I've hired."

— Elena R., Self-Help Author

"Scary accurate. It pinpointed exactly why my description wasn't hooking readers. 10/10 for precision."

— David K., Thriller Author
