Frequently Asked Questions

What is a good keyword density for SEO?+
There's no strict rule, but most SEO practitioners aim for roughly 1–2% density for a primary keyword — natural, readable usage matters far more than hitting an exact percentage.
Can keyword stuffing hurt my rankings?+
Yes — repeating a keyword unnaturally can trigger search engine spam filters and make content read poorly for users, which hurts both rankings and engagement.
Are common words like "the" and "and" included?+
No — common stop words are automatically filtered out so the density results focus on meaningful keywords and phrases.
