Keyword Density Checker — FAQs

What is a good keyword density?
A balanced keyword density typically falls between 1% and 3% for primary keywords. This means your keyword appears one to three times per 100 words of content. Overusing a keyword beyond ~3.5% can be perceived as keyword stuffing and may harm rankings. Underusing may dilute relevance.
Should I exclude stopwords?
Stopwords are common words like "the", "and", "to" that search engines often ignore. Excluding them focuses your analysis on meaningful keywords. However, including them can give you a picture of your overall vocabulary. Use the toggle based on what insights you want.
Can I use this for languages other than English?
This tool provides best results for English text because the stopword list and suggestions are tailored to English. For other languages, results may vary. You can set stopword exclusion to "No" and manually interpret the data.
Will this tool improve my rankings automatically?
No. The keyword density checker provides data and recommendations. It’s up to you to apply these insights. Combine this analysis with quality content, proper metadata, backlinks, and a comprehensive SEO strategy for the best results.
