Your blurb is doing more selling than your book

Nobody buys a book because chapter nine is brilliant. They buy because the blurb — the 150 words on the product page — made them. It’s the single most-read passage you’ll ever write, and it’s where a browsing reader becomes a buyer, or keeps scrolling.

Blurb Doctor reads your blurb the way the market does. It scores the hook, the genre signals, the stakes, the clarity, and the close; flags every line that’s costing you the click; and hands back two rewritten blurbs you can paste straight into Amazon. It tells you what’s weak — and gives you the cure.

Why authors buy it

Tiny cost, outsized leverage

 

The diagnosis is free

See your score and scorecard before you pay anything.

$10 on the words that sell

You get rewrites, not just notes

Two finished blurbs, ready to paste — not a list of complaints.

Calibrated to your genre

A romance blurb and a thriller blurb aren’t judged the same way.

It diagnoses — you stay the author

The rewrites are strong starting points; your voice stays yours.

Re-score as you revise

Paste the new version back anytime and watch the score climb.

Questions

Good to know

 

Is the diagnosis really free?

Yes. Your score and the five-point scorecard cost nothing. The fixes and the rewrites are 2 credits.

What do I get for 2 credits?

A section-by-section read, every weak line flagged with a fix, a genre-fit check, two full rewritten blurbs, and a priority fix list.

Will the rewrites sound like me?

They’re strong, paste-ready starting points built from your own blurb — adjust them to taste; the voice stays yours.

Which genres does it cover?
