Recently, I did a detailed study on keyword density analysis by comparing the Google’s top 10 search results.

The outcome of the research: keywords on title and keywords across multiple elements of the page are playing a major role in ranking.

Interestingly, I found there were no keywords used on the image alt tags on those top 10 results.

The learning is that keyword has to be used on multiple elements of the page right from Title, Body Text, Links in a natural way.

That means you should not stuff your page with too many keywords instead you have to use it on required places. This way, your pages will be optimized perfectly for the search engines and also, it will carry necessary information for the reader.

However, there is no specific optimum keyword density.

According to Google, it should not be over density because it means you are spamming.

In this article, I will be listing few of the best free keyword density analysis tools available in the market.

#1 – SEO Book’s Keyword Density Analyzer Tool

This is one among the famous tools that I use most of the time.seobook keyword density analyzer

You can input your URL or simply, paste the content and click “Submit”. If you are inputting URL then you can choose between, what are all the elements to take for analysis.

For example, you can include or exclude Meta Description from your analysis or Page Title etc.

The results looks like below:seobook keyword density result

It shows the overall density and also, for the specific element like text only, title only etc. It has the option to exclude “stop words” or you can input your own “stop words”.

#2 – Small SEO’s Keyword Density Checker

There are lot more tools available to calculate the keyword density of your writing as well as pages.

Apart from these 2 tools remaining are just keyword tools without much value add.

When it comes to keyword density, you also keep these 2 simple points in mind:

  • Don’t over stuff keywords in your writing and keep the keywords to flow naturally.
  • Don’t forget to use that targeted keyword on Title, Body, Links, Images.
