Keyword Density Analyzer


The Keyword Density Analyzer is a free web application tool that tallies the different words in a given text and counts the occurrences of each word. The analyzer then reports the words in order of occurrence: starting with the highest down to the lowest.

Keyword density gives the sense of what a document is about. It is often used by robots to sort through resumes and by search engines when analyzing the content of a web page. Since machines do not understand text in the same way that humans do, this tool will give you a good idea of what a machine sees in a given document. Once you remove the lightweight words such as “the”, “and”, and so on from the results you are left with the major nouns, verbs, adjectives, and adverbs that give the essence of the document. A resume where the most occurring word is “electrician”, for example, is mostly likely about an electrician.

When you are writing a document that will be read by both humans and machines this tool gives invaluable insight into what a robot would see in your document.
