Frequently Asked Questions
What is keyword density?
Keyword density is the percentage of times a keyword or phrase appears in a piece of text relative to the total word count. It is calculated as (keyword occurrences / total words) x 100, and is used as a rough signal of how heavily a page targets a specific term.
Ideal keyword density for SEO?
There is no official ideal percentage, but most SEO practitioners aim for roughly 1-2% density for a primary keyword. Writing naturally for readers and including related terms and synonyms matters more than hitting an exact number.
Does Google penalize keyword stuffing?
Yes. Google's algorithms can detect unnatural keyword repetition and may demote pages that read as stuffed or manipulative rather than genuinely useful to readers. Google explicitly lists keyword stuffing as a violation of its spam policies.
Keyword density vs TF-IDF?
Keyword density is a simple raw percentage. TF-IDF (Term Frequency-Inverse Document Frequency) is a more advanced measure that weighs a term's frequency in your text against how rare it is across a larger set of documents, giving a better signal of topical relevance.
