There is no perfect percentage required by Google. If you ask what is a good keyword density for SEO, the answer is whatever percentage sounds completely natural to a human reader.
Do not chase an artificial number like 1% or 2%. Keyword frequency is a diagnostic signal, not a ranking target. If you write about "stainless steel bolts," you will naturally use that phrase many times to explain the subject. Focus on clear readability, answering the search intent, and building good topical coverage. Avoid unnecessary repetition, but do not delete a keyword if the sentence needs it to make sense.
Keyword density is a simple measurement of how often a word occurs. Keyword stuffing is an unnatural manipulation of text intended to trick search engines.
Natural usage sounds like this: "We sell custom wooden chairs. Browse our catalog to find the perfect fit for your dining room."
Keyword stuffing sounds like this: "Buy custom wooden chairs because our custom wooden chairs are the best custom wooden chairs."
A high keyword density does not always mean you are stuffing keywords, but it often warns you that the text might be hard to read.
Checking your content frequency is highly useful in a few specific situations:
Before publishing a new article.
After performing a major SEO edit.
When updating old content that dropped in search rankings.
When checking paragraphs that feel repetitive.
After checking keyword usage, you can use the SEO Analyzer for a broader look at your page's SEO elements.
Writers often misunderstand how to optimize their text. Avoid these frequent errors:
Forcing the exact-match keyword into every single paragraph.
Chasing a fixed percentage because an old SEO blog recommended it.
Repeating the exact same phrase when a simple pronoun would work better.
Ignoring related terms and semantic keywords that naturally belong in the article.
Sacrificing readability just to make a tool happy.
