7 Amazing Tools To Check Keyword Density

One of the challenges with SEO analysis is finding the right tool to conduct your keyword densitykeyword density check. Some content publishers are happy to publish their material and then check it after it has been published. However, others prefer to do their analysis prior to publishing it. This post aims to review 7 amazing keyword density checker tools for publishers who already have their content online and also for those who prefer to develop their content offline.

How To Check Keyword Density Of Content Already Published Online?

There are a number of different tools that you can use to assess the density of content that has already been published online.  The options here are to use (1) a website tool where you insert the URL address of the page that you want to check, (2) use a plug-in for your Content Management System (CMS) or (3) use a internet browser plug-in tool.  I have listed a number of tools that are worth considering below.

1. Website Keyword Density Checker Tool

I recommend using SEOBook Keyword Density Checker to perform your check on a specified web page – just enter the URL address.  This is an excellent tool that is very easy to use and provides you with a list of one word, two word and three word phrases and associated density data.  In my view this tool is better than the vast majority of free online apps that either don’t work or take a bit of tweaking to make work.

2. WordPress Keyword Density Checker Plug-in

Before publishing Content Management System content it is useful to be reassured that content is not going to get flagged as potential spam.  Perhaps more importantly this analysis can be used to make sure that you have not missed an angle within your work.  It is all too easy to under emphasize phrases that keyword research has indicated are being searched for in the search engines.  You can check WordPress content using the SEO Keyword Density Checker Tool plug-in.  It provides all the key data that you need in a table below your WP post or page material.  It provides you with a list of one word, two word and three word phrases and allows you to either include or exclude stop words.  However, this tool has not been updated for a while, which may be worth considering before you install.

 3. Internet Browser Keyword Density Checker

Until I came across SEO Quake my keyword density checks were much more time consuming.  What I love about the SEO Quake Browser Tool is that it is easy to install and right out of the box it works.  It works for checking your content and works for getting ideas from your competitors web sites.  I quote it often to my clients as being my number one SEO tool.  I strongly recommend that you consider adding it to your SEO toolkit unless you have already done so.  The tool has been developed for the Mozilla Firefox Browser, and more recently for Chrome, Opera and Safari browsers.  You can download the tool at SEOQuake.com.  Why not test it out today?

How To Check Keyword Density Of Content NOT Published Online?

If you already have online content it is a piece of cake to check your page content, but what if you don’t have a CMS or just simply want to check the content that you have produced in a word processor such as Microsoft Word?  Then you need a different type of tool.

Recently I spent some time researching the net to give a client of mine a few options for how they could assess their content before they published their work. This essentially means pasting word processed content into a free online app. The tools more widely available generally fall into two categories: (1) evaluating the density of predefined phrase/(s) within your text (usually limited to 2-3 terms to check for) and (2) evaluating the density of keywords for a piece of text, which provides unlimited data on keyword phrases in the text.

4.Keyword Analyzer Tool For Pasted Text – Data For Predefined Keywords Only

The live-keyword-analysis.com tool is good. You are able to copy and paste your word processed content into the required fields.  You then highlight your specific keyword that you want to conduct analysis on.  There is an alternative tool at  webcopyplus.com which does a similar job.  However, the above two tools provide you with no statistical data about all the keywords and phrases on the page – including the ones that you are not aware have an unintended high prominence within your material.

5.Keyword Analyzer Tool For Pasted Text –  Data for Unlimited Keywords

The following free tools allow you to simply past text into an online tool that tells you the frequency of all single words, two word, three word and four word keywords. These are not necessarily all the same as some may suit your needs better depending what you wanting your SEO keyword analysis tool to do.

When I first came across the kessor.net keyword density tool I was very excited.  The tool is not flashy or gimmicky.  It just gives you exactly what you need – an analysis of your content. The only issue is that the data is hard to extract if you want to do in-depth offline analysis. So consider one of the tools below if data extraction is important for you in a keyword analyzer tool.

The tool hosted by keyworddensitytool.com is one that I have started to use with some clients who are developing their website content offline.  Using this tool you can run some cool keyword analysis for your content which you can easily copy and paste into a word processor to analyse later.  However, I have noticed that this tool gives lower density data than other tools.  This I presume is because other tools are excluding stop words.  My approach is to use the output data as informative, but the key measure is how your page is performing in the search engines.  Where a page under performs for a keyword it is worth adjusting depending on whether the data indicates that the keyword is under exposed or over exposed.

6. Keyword Density Calculator – Source Code for Developers

A curious tool hosted on Alex Poole’s site is a low frills tool on the surface.  However, this is an excellent tool. You just add your content and then press “go”. The result is three columns of data in terms of keyword phrase, frequency of occurrence and density of keyword. In addition, Alex has given permission to use the source code as long as we link back to his site.  Thanks for sharing the code Alex.  I will be adding the tool to this site!

7. Keyword Analyzer – Scripts and Macros

The above online tools provide you with the ability to assess specific keywords by pasting information into an online tool. Whilst there are no known issues doing this you may prefer to use an application such as Microsoft Excel to achieve a similar end result. Whilst I have found a number of macros online so far I have not been able to source a reliable tool in Microsoft Excel, but I’ll re-post when I do find one for the completeness of this post.  However, at a very simplistic level what you can do is perform (A) a total word count on your text and then perform a find and replace identifying (B) the frequency of the phrase.  Then calculate (B/A)*100 to establish your keyword density.  However, this has limitations in terms of only being able to calculate the formula for one keyword or keyword phrase at a time and no way to remove stop words from the analysis.

I hope that you have found this post useful and have got some value from it.  I’d love to hear about the keyword density checker tools that you have used and please let me know if I have missed any key tools out.  So please scroll down and leave a comment.
