Frequently asked questions
What is keyword density and what's the ideal range?
Keyword density = (keyword occurrences ÷ total words) × 100. Modern SEO best practice is 1–2% for your primary keyword. Anything above 3–4% risks being flagged as keyword stuffing by Google.
Does keyword density still matter in 2025?
Less than it used to. Google now uses semantic understanding (BERT, MUM) over raw keyword counts. But density is still a useful sanity check — it helps you spot stuffing and confirm your topic is clearly addressed.
Why does this tool ignore stopwords?
Words like 'the', 'and', 'is' appear in almost every sentence and don't reflect topical focus. Removing stopwords from 2-word and 3-word phrase analysis surfaces the actual keyword themes in your content.
Is the analysis done in my browser?
Yes. All processing runs client-side in your browser — your content never leaves your device. We log only anonymous word counts to improve the tool.
