Frequently asked questions
What is a good keyword density?
There's no strict ideal percentage - modern SEO focuses more on natural language and topical coverage than hitting a specific density target. As a rough guide, 1-2% for your main keyword is common, but writing naturally for readers should always come first.
Can too high a keyword density hurt my SEO?
Yes - 'keyword stuffing' (unnaturally repeating a term) can trigger spam signals and hurts readability, which can work against your rankings rather than helping them.
Does this analyze a live URL or pasted text?
Enter any live URL and the tool fetches and analyzes that page's actual on-page content directly - no need to copy and paste text yourself.
