Density is how often a term appears versus your total word count. There is no magic number, but a single term above roughly 4% often reads as stuffed to both Google and AI answer engines. Aim for natural coverage of your topic and related entities instead. Score the same content for AI citability, or let SmashSERP write it.
Keyword density FAQ
What is a good keyword density?
There is no exact target. Google stopped rewarding raw density years ago and now reads topic and entity coverage. As a safety rail, keeping any single term under about 4% avoids looking stuffed. Focus on covering the subject naturally, including related terms, rather than repeating one keyword.
Does keyword density still matter for SEO?
Not as a ranking lever on its own. It matters as a diagnostic: very high density signals stuffing, and very low density on your target term can mean the page is not clearly about it. Use this to catch both extremes, then write for the reader and for AI answer engines.
Why does it show two and three-word phrases?
Most real search intent is multi-word. Seeing your top two and three-word phrases tells you what the content is actually about and whether it matches the query you are targeting, which single-word counts hide.
Does this send my content anywhere?
No. The analysis runs entirely in your browser. Nothing you paste is uploaded or stored.
