Frequently Asked Questions

What keyword density should I aim for on Amazon?

1-3% density on your primary keyword is generally healthy; above 3% starts to read as keyword stuffing, which this tool flags in red.

Should I filter out stopwords?

Yes for most analysis — filtering words like "the" and "and" surfaces the meaningful keywords and phrases readers actually search for.

Does this check backend keywords too?

You can paste your backend keyword string directly into the analyzer alongside your description to see how phrases repeat across both.
