Frequently Asked Questions
What is keyword density?
Keyword density is the percentage of times a keyword appears in your content compared to the total number of words. For example, if your article has 100 words and a keyword appears 3 times, its density is 3%.
What is the ideal keyword density for SEO?
Most SEO experts recommend a keyword density between 1% and 3% for your primary keyword. Going higher can be seen as keyword stuffing by search engines, which may negatively impact your rankings.
Why should I exclude stop words?
Stop words (like "the", "is", "at") are extremely common and don't carry meaningful SEO value. Excluding them helps you focus on the keywords that actually matter for your content optimization.
