Frequently Asked Questions
What is keyword density and why does it matter for SEO?
Keyword density is the percentage of times a keyword appears relative to the total word count. For SEO, having your target keywords appear naturally (typically 1–3% density) helps search engines understand your content's topic. Keyword stuffing (unnaturally high density) can lead to penalties.
What are stopwords?
Stopwords are common words like "the," "a," "is," "and" that appear frequently in all text but carry little meaning for keyword analysis. Filtering them reveals the meaningful keywords in your content. Toggle the stopword filter off if you want to see all words including common ones.
What is a good keyword density for SEO?
There's no single magic number, but 1–2% density for your primary keyword is a reasonable guideline. More important is natural, contextually relevant usage. Modern search engines understand topic modeling and synonyms — focus on covering a topic thoroughly rather than hitting a specific density.
