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.

What is the optimal keyword density for SEO?

While there is no official rule, most SEO experts recommend maintaining a density between 1% and 2.5% for primary keywords. Going above 3% may trigger search engine keyword stuffing filters.

What are N-grams in keyword analysis?

N-grams are sequences of contiguous words. 1-word keywords are unigrams, 2-word key phrases are bigrams, and 3-word combinations are trigrams.

Does this tool strip HTML tags?

Yes. When enabled, our parser strips header tags, scripts, CSS blocks, and standard DOM elements, leaving behind only the indexable copy text for checking.
