What is the Keyword Density Analyzer?
Search engines read a page's words to work out what it's about — and so should you. If the terms you want to rank for barely appear, or a stray word dominates because of boilerplate, your page may be sending the wrong signal without you realizing.
This keyword density analyzer fetches any live page and shows its most common words and phrases, each as a share of the total, so you can see what the page actually emphasizes.

What does this tool do?
You enter a URL and the tool fetches the page, strips out scripts and styling, and counts every word and two- and three-word phrase in the visible text.
It reports the top keywords and phrases with their density, and checks whether your leading terms appear in the title, H1, meta description and URL.
