Frequently Asked Questions
What is keyword density and why does it matter for SEO?
Keyword density is the percentage of times a keyword appears in your content relative to the total word count. It matters because search engines use keyword frequency as one signal to determine what a page is about, though over-optimization (keyword stuffing) can lead to penalties.
What is the ideal keyword density for SEO?
Most SEO experts recommend a keyword density between 1% and 3% for your primary keyword. Going above 3% risks being flagged as keyword stuffing by search engines, while going below 1% may not provide enough signal for relevance.
How does the keyword density checker work?
Paste your content into the text area and the tool instantly analyzes word frequency, calculates density percentages, and ranks keywords by occurrence. You can also set a target keyword to see its specific density and distribution throughout your text.
What are stop words and should I filter them out?
Stop words are common words like "the," "is," "and," and "in" that carry little meaning on their own. Filtering them out gives you a clearer picture of your content's meaningful keyword usage and helps identify the terms that actually contribute to your SEO.
Why does the tool also show two-word phrases?
Two-word phrases (bigrams) reveal how keywords are used in context, which is important for long-tail SEO. Search engines increasingly understand phrase-level meaning, so analyzing multi-word combinations helps you optimize for more specific and targeted search queries.
