Frequently Asked Questions
What is keyword density?
The percentage of your total word count made up by one specific word or phrase. If "coffee" appears 10 times in a 500-word article, its density is 2%.
Is there an ideal keyword density for SEO?
No fixed target — modern search engines evaluate topical relevance and context, not a magic percentage. This tool is more useful for spotting accidental over-repetition (which can read as keyword stuffing) than for hitting a specific number.
What does "exclude common words" do?
It filters out stop words — extremely frequent connector words like "the," "and," "is," and "a" — so the results surface the meaningful, topical words instead of words every piece of text contains.
What's the difference between single words and phrases?
Switching to 2-word or 3-word phrases groups consecutive words together (e.g. "content marketing" or "content marketing strategy"), which often reveals repeated multi-word keyword phrases that single-word analysis misses entirely.
