10 Free SEO Keyword Density Tool, Checker & Analyzer

Free SEO Keyword Density Tools

I was a bit worried about the Keyword Density (which is the percentage of times a keyword or keyword phrase appears on a web page compared to the total number of words on the page) for some of the previous articles. I asked myself ‘Have I over-optimized the posts?’. Of course, I haven’t done any Keyword Stuffing (practice of loading a webpage with keywords to manipulate search engines) but I did add keywords to meta-keywords and meta-description. But I believe that I used keywords appropriately and in context.

Google has already taken steps to penalize overly SEO’ed websites. So let’s be careful when writing an article. But how? Just keep your Keyword Density at around 3%. I did some research on keyword stuffing and density and I find that 2–3% is the ideal SEO Keyword Density percentage. But according to Submit Edge, one of the top Search Engine Optimization company, it should be between 1–2%. That too for a single word keyword. I find it very difficult to keep the density of single word keywords in that range. So I guess 2–3% is ideal.

So I Googled to find the Best Keyword Density Tools/Checker/Analyzer. But it returned a lot of results and there were tons of paid and Free Keyword Density Tools. I tried few of them and want to to list only the best among them which are free.

Wait! What Is SEO Keyword Density And How To Calculate It?

What is Keyword Density?

Keyword Density is the percentage of times a keyword or keyword phrase appears on a web page when compared to the total number of words in that page. As the number of times a keyword appears in relation to the total number of words, the greater will be the keyword density of the page. Read more about Keywords and Keyword Research.

So, how do you calculate the Keyword Density of an article? It’s simple! Just count the number of times a keyword or keyword phrase has appeared in an article and divide it by the total number of words in the article (including the keyword or keyword phrase). Now, get it’s percentage and that’s the keyword density of that article.

What is the Ideal Keyword Density of a page according to Google’s Matt Cutts?

What is the Optimum Keyword Density of a webpage?

Well, some SEO experts says there is no such thing as ‘Optimal Keyword Density’ and it’s a myth. Some says it must be around 2% and some says it must be less than 5% and so on. But I believe that they could all be right. Why? Just because it depends on the length of the article which we have written. Hence, the optimal keyword density of a webpage depends upon the total number of words in that page.
