Frequently asked questions
What is keyword density and what percentage should I target?+
Keyword density is how often a keyword appears relative to total word count. There is no perfect number, but most SEO guides suggest keeping primary keywords between 1 and 3 percent to avoid appearing spammy to search engines.
Does the tool analyze multi-word phrases?+
Yes. It extracts unigrams, bigrams, and trigrams so you can see density for single words and for two-word and three-word phrases. This helps you spot repetitive phrasing that reads unnaturally.
Does high keyword density improve rankings?+
No. Modern search engines use semantic understanding and can penalize keyword stuffing. The tool helps you find a natural balance rather than hitting an arbitrary percentage target.
Is my content sent to a server for analysis?+
No. All frequency counting and density calculations run locally in your browser. Your text stays on your device, making it safe to analyze drafts or confidential content.
Are common words like "the" and "is" filtered out?+
Yes. Stop words are excluded from the results so you see only meaningful keywords. The tool uses a standard English stop word list to keep the output actionable.
