Keyword Density Analyzer Tool

On-page Classifiers

When Google rolled out the first Penguin update in April of 2012, they also rolled out some on-page classifiers which penalized some pages that had excessive word repetition.

In this day and age the primary use of these types of analysis tools is not to keep dialing up the keyword density, but rather to lower the focus on the core terms while including alternate word forms, accronyms, synonyms & other supporting vocabulary.

The video to the right discusses optimizing your on-page SEO strategy both for conversions & to include keyword variations in the content.

Overdoing Keyword Density

Please note that due to web spam, density by itself is a fairly poor measure of relevancy (see slides 17 through 20 in this 2004 PDF from Google's Amit Singhal).

Early / primitive search technology was not very sophisticated due to hardward & software limitations. Those limitations forced early search engines like Infoseek to rely heavily on-page document scoring for relevancy scoring. Over the past 15 years search engines have grown far more powerful due to Moore's law. That has allowed them to incorporate additional data into their relevancy scoring algorithms. Google's big advantage over earlier competitors was analyzing link data.

Dr. E. Garcia explained why density was a bad measure of relevancy in The Keyword Density of Non Sense.

Should I Even Use Density Analyzer Tools?

These types of tools are still quite valuable when used with the right strategies. The above points were referenced trying to fix old issues from outdated tips & was really just mentioning how 'optimizing' for some arbitrary exact density often misses the mark.

Using analysis tools can still help you uncover a lot of opportunities, including:

When I first got in the SEO game I remember some tools trying to tell me to tweak into these stupid arbitrary exact percentages & realizing (after the fact) how futile that was only fuled my rage toward such tools. So we created this tool to serve the legitimate functions of keyword density tools AND warn against some of the futile (& even counter-productive) uses as well. ;)
