Amazon Product Keyword Density Analyzer

Which words actually repeat in your listing copy

The sample copy 'stainless bottle leakproof bottle hiking bottle BPA-free stainless lid' tokenizes into 10 words, with 'bottle' appearing 3 times, 'stainless' 2 times, and 'leakproof', 'hiking', 'bpa', 'free', and 'lid' each appearing once.

'Bottle' at 3 of 10 tokens (30% of the counted words) is the dominant term in this sample -- exactly what you'd want for the primary product keyword to be the most frequent, confirming the listing copy is actually centered on its main search term rather than diluted across too many competing phrases.

Notice 'BPA-free' splits into two separate tokens ('bpa' and 'free') rather than being counted as one compound term -- a reminder that simple word-based tokenization treats hyphenated or compound product terms as their individual parts, which can undercount how often a specific compound phrase like 'BPA-free' actually appears together.

What this tool checks, and what it doesn't

Counts tokens of 3+ letters. Not a ranking or indexing report. Short words (under 3 letters, like 'a', 'of', 'to') are excluded from the count entirely, since they're rarely meaningful search terms and would otherwise dominate a frequency count without adding insight.

This is a raw frequency count of your own pasted copy -- it says nothing about how Amazon's A9/A10 search algorithm actually weighs or indexes these terms, which depends on many factors (backend search terms, category, conversion rate, sales velocity) well beyond front-end copy word frequency.

Keyword stuffing (repeating a term far beyond natural, readable usage) can hurt conversion even if it might seem to help density -- use this as a check that your primary keyword appears naturally and prominently, not as a target to maximize at any cost.

Building out the rest of the listing

Once keyword usage in the visible copy looks right, character length is the other constraint to check -- see the Amazon Listing Title & Bullet Counter.

For podcast or blog content instead of a product listing, the Podcast Transcript SEO Keyword Density Checker applies similar logic to a different content type.
