FAQ
How is keyword density calculated?
By dividing how many times each significant word appears by the total word count (excluding common stop words like "the" and "and"), expressed as a percentage.
Why are common words excluded?
Stop words like "the," "and," and "our" appear frequently in any text but carry little topical meaning - excluding them surfaces the words that actually indicate what your content is about.
What does word size in the cloud represent?
Larger, more opaque words appear more frequently in your text - the cloud gives an instant visual sense of your content's dominant topics.
What is a healthy keyword density for SEO?
There's no strict rule, but very high density (over 3-4% for a single term) can look like keyword stuffing to search engines - natural, varied language is generally safer.
