Frequently Asked Questions

What is keyword density?

Keyword density is the percentage of times a target keyword appears in your content compared to the total word count. A 2% density means about 20 occurrences per 1,000 words.

What is the ideal keyword density for SEO?

There's no magic number. 1 to 2% is commonly cited as a rough guideline, but Google doesn't use keyword density as a direct ranking signal. Natural, helpful writing that fully answers the query matters far more.

What is keyword stuffing and why does it hurt rankings?

Keyword stuffing is repeating a keyword excessively to try to manipulate search rankings. It reads unnaturally to visitors and can trigger Google's spam filters, leading to lower rankings instead of higher ones.

How do I check keyword density for a competitor's page?

Switch to "Check a URL" mode above and enter their page URL. This reveals which keywords and phrases they emphasize most, useful competitive intelligence for your own content brief.

Should I use exact-match keywords or synonyms?

Mix both. Use your exact target keyword where it reads naturally, and fill in with synonyms and related terms (sometimes called LSI keywords). Google understands meaning and topic relevance, not just exact phrase matches.
