Keyword Density Analyzer adds a sidebar meta box to the Classic and Gutenberg post/page editors. Enter a focus keyword in the meta box and the plugin instantly analyzes your content, showing keyword count, density percentage, total word count, and whether the keyword appears in the post title, H2 headings, H3 headings, and the first paragraph. A color-coded density badge (green/yellow/red) gives an at-a-glance quality signal. The focus keyword is saved as post meta alongside the post.
