Frequently asked questions
What is keyword density?
Keyword density is the percentage of times a word or phrase appears compared to the total word count of your content. It’s calculated as (count ÷ total words) × 100.
Is there an ideal keyword density for SEO?
There’s no universal magic number, but many writers aim to keep any single keyword under roughly 1–2% of total words to avoid content looking over-optimized or “keyword-stuffed” to search engines.
Why should I ignore stop words?
Stop words like “the”, “is”, and “and” appear frequently in any text but carry little SEO signal. Filtering them out surfaces the meaningful keywords and phrases in your content instead.
