The Keyword Density Checker is a text analysis tool that calculates the frequency and density percentage of words within a given block of text. It helps identify overused words, optimize content for SEO, and ensure a natural distribution of keywords throughout your writing.
Como usar Keyword Density Checker

- Adjust the minimum word length to exclude very short words if needed.
- Toggle 'Filter stopwords' to include or exclude common English words like 'the', 'is', and 'at'.
- Set how many top keywords you want displayed.
- Review the bar chart showing each keyword's count and density percentage.

Erros comuns
- Keyword stuffing — forcing a keyword into text until it reads unnaturally. Aim for 1–2% density and natural language.
- Ignoring long-tail keywords — single-word analysis misses multi-word phrases that often drive more targeted traffic.
- Leaving stopwords unfiltered — when filtering is off, results are dominated by words like 'the' and 'and' instead of meaningful keywords.
