Frequently Asked Questions
What is Keyword Density?
Keyword density is the percentage of times a keyword or phrase appears on a webpage compared to the total number of words on that page. It is a metric used by SEO specialists to ensure a page is relevant to target search queries without crossing into over-optimization.
What is the ideal keyword density for SEO?
While search engines like Google do not enforce a strict numerical target, a safe and natural keyword density is typically between 1% and 2.5%. Going above 3.5% may trigger keyword stuffing flags, which can negatively impact search rankings.
What are stopwords, and why does this tool filter them?
Stopwords are high-frequency words in a language (like "the", "is", "at", "which", "on") that convey grammatical structure rather than topical meaning. Filtering them out allows you to identify the actual core keywords that search engines use to understand the page's topic.
