What is Keyword Density?
Definition
Keyword density is the percentage of times a target keyword appears in a page's text relative to total word count. Once treated as a key ranking signal, modern SEO deprioritises keyword density in favour of topical relevance and natural language. Overuse (keyword stuffing) actively harms rankings.
Why Keyword Density matters for Shopify stores
Shopify merchants sometimes over-optimise product descriptions by repeating keywords unnaturally. Modern best practice is to write naturally for the customer, use synonyms and related terms, and trust AI-assisted generation to find the right balance — not chase a specific percentage.
Shopify example
A pet store writes 'Our premium dog food for dogs is the best dog food for your dog's health' — three unnecessary repetitions. Better: 'Premium nutrition for your dog, formulated for long-term health.' Same relevance signal, far more readable.

- ✕ Targeting a specific percentage (e.g., '2% density') — this is outdated advice
- ✕ Repeating the exact same keyword phrase when synonyms would read more naturally
- ✕ Stuffing keywords into alt text, footer, or hidden elements
- ✕ Ignoring semantic keywords and related terms in favour of exact-match repetition
