Frequently Asked Questions
What is a good keyword density for SEO?
A keyword density of 1-2% is generally ideal. Above 3% may trigger keyword stuffing penalties from search engines.
How many times should I use my main keyword?
In a 1,000-word article, use your primary keyword 10-20 times (1-2% density). Spread it naturally across headings, intro, and conclusion.
What is Flesch-Kincaid readability?
