Free Amazon Listing Keyword Density Checker

Check keyword frequency and density in your Amazon listing copy.

Amazon's A9/A10 search algorithm weighs keyword relevance heavily, but stuffing keywords unnaturally can hurt conversion rate (which also affects ranking) even if it doesn't directly penalize you. Use this to check whether your primary keywords appear a reasonable number of times without looking robotic to a human shopper.

Worked Example

Example: Paste your full listing copy (title + 5 bullets + description). If "stainless steel water bottle" appears 8 times across 200 words, that's roughly 4% density for that phrase — worth checking it still reads naturally rather than repetitively.

Formula

Keyword Density % = (Keyword Occurrences / Total Word Count) × 100

Frequently Asked Questions

Does this send my listing text anywhere?
No — everything runs in your browser via JavaScript. Nothing is uploaded or stored.
What density is too high?
There's no official Amazon threshold, but if a phrase reads unnaturally when you say it out loud, it's probably over-optimized — prioritize readability for shoppers.
