Frequently asked questions
What is a good keyword density?
For most content, keep your primary keyword roughly between 0.5% and 2%. Above 3% it reads as over-used, and above 5% search engines may treat it as keyword stuffing.
Does this tool count stop words?
You can toggle stop-word filtering on or off. With it on, common words like 'the', 'and' and 'of' are removed so the ranking reflects meaningful keywords.
