The Problem

Why most KDP authors struggle with this.

You wrote your title based on what made sense to you. But Amazon's search algorithm doesn't care what makes sense - it cares what gets typed. If your book's title, subtitle, and backend keywords don't match what readers actually search, Amazon will never show your book to them. You could have the best book in your niche and still sell nothing.

Without Keyword Research:

✗ You're making decisions based on guesses
✗ Your competitors have data you don't
✗ You're losing sales every day to avoidable mistakes

With Keyword Research:

✓ Know which keywords are worth targeting before you write your next title
✓ Stop competing on saturated terms and find the underserved pockets
✓ Understand why competitors rank where they do
✓ Export results to CSV for your own analysis

The Solution

How PublishRank solves it.

PublishRank analyzes real Amazon search behavior for any topic or keyword phrase. We score every variation across three dimensions - demand (how many people search for it), competition (how hard it is to rank), and opportunity (the sweet spot between the two). You get a ranked list of the best keywords to target, with a single Opportunity Score so you don't have to do the math.

How it works.

Three steps from sign-up to insight.

Enter a seed keyword

Type any topic, phrase, or genre. We generate up to 10 related keyword variations automatically.

We analyze real Amazon data

We score each variation for search demand, competition level from current top books, and overall opportunity.

Get your priority list

Every keyword gets an Opportunity Score. Sort by score, pick the winners, and add them to your listing.

PublishRank's Flagship

Daily book monitoring keeps this tool current.

PublishRank's flagship feature is daily Amazon book monitoring. Every book you add to your account is scanned every day for BSR shifts, new reviews, ranking changes, and bestseller badges - with instant email alerts the moment something happens and a weekly Monday digest summarising every book in one email.

This tool sits on top of that monitoring data. Your scores, gaps, and recommendations refresh automatically as your real-world metrics change, so the advice you see today is based on what's true today - not a snapshot from last week. It's the difference between a one-time research tool and a live intelligence platform.
