Optimum SEO Keyword Density A Real Life Case Study

Optimum SEO Keyword Density A Real Life Case Study

So you’ve built your website,​ you​ know what keywords you​ want to​ target (i.e. what words your customers are searching for),​ and you’re ready to​ write your copy. You’ve been told that you​ should use your keywords frequently so that you​ appear in​ search results for those words. But what does “frequently” mean?

How many times should you​ use your primary keyword? This case study helps answer that question.

Some background on​ ”Keyword Density”

In order to​ understand optimum keyword usage,​ we first need to​ have some way of​ measuring keyword frequency. in​ the​ Search Engine Optimization (SEO) world,​ frequency is​ actually referred to​ as​ density. Keyword density is​ a​ measure of​ the​ number of​ times your keyword appears on​ a​ page expressed as​ a​ percentage of​ the​ total wordcount of​ that page. For example,​ if​ your page has 100 words,​ and your keyword phrase appears 5 times,​ its density is​ 5%. So when you​ hear someone say “keyword density”,​ that’s normally what they’re talking about. (TIP: you​ can automatically check the​ keyword density of​ your page at​ LiveKeywordAnalysis.com.)

However,​ there is​ another,​ more complex measure of​ keyword density which takes into account the​ text components in​ the​ HTML of​ the​ page (i.e. the​ meta tags: Title,​ Keywords,​ Alt Text,​ Description,​ and Comments). When using this measure,​ you​ don’t just count the​ words your visitor sees; you​ also count the​ words in​ your meta tags. For example,​ if​ you​ have 100 words on​ your home page,​ 10 words in​ your Title tag,​ 20 words in​ your Description tag,​ 70 words in​ your Alt tags,​ and 10 words in​ your Comments tag,​ your total wordcount for the​ page is​ 100 + 10 + 20 + 70 + 10 = 210. Similarly,​ when counting keywords,​ you​ don’t just add up the​ number of​ times a​ visitor will see your keyword,​ you​ also count the​ number of​ times that keyword appears in​ your meta tags. For example,​ if​ your keyword appears 5 times in​ the​ home page copy,​ 3 times in​ the​ Title tag,​ 5 times in​ the​ Description tag,​ 30 times in​ your Alt tags,​ and twice in​ your Comments tag,​ your total keyword count is​ 5 + 3 + 5 + 30 + 2 = 45. So with a​ total wordcount of​ 210 and a​ keyword count of​ 45,​ your keyword density is​ 45/210 x 100 = 21%. it​ is​ argued that this measure of​ keyword density is​ more relevant as​ the​ search engines measure density in​ this fashion. (TIP: you​ can automatically check the​ keyword density of​ your page using this more complex measure at​ GoRank.com.)

As you​ can see,​ you​ need to​ be very aware of​ which measure you’re talking about when you’re talking “keyword density”. But let me reiterate; mostly when people talk about keyword density,​ they’re talking the​ simple measure.

What is​ the​ optimum keyword density

And now down to​ business… What keyword density (of either kind) should you​ be targeting on​ your website?

There’s a​ lot of​ debate surrounding this issue because the​ search engine companies don’t disclose the​ details of​ their algorithms (as that would allow people to​ abuse the​ system). Instead,​ people working in​ the​ SEO world are left to​ figure it​ out based on​ their experience.

A recent article by respected SEO and Blog expert,​ Wayne Hurlbert,​ (see Keyword Density: SEO Considerations) suggests that Google sees pages with a​ keyword density of​ greater than 2% as​ spam. it​ was this article which prompted me to​ analyze the​ keyword density of​ my copywriting website.


The Website: This case study analyzes the​ website for my advertising copywriting and SEO copywriting business,​ Divine Write – http://www.divinewrite.com. For my primary keyword,​ my site is​ now on​ page 1 of​ Google.com (out of​ approximately 900,​000 search results).

Number of​ pages on​ site: at​ the​ time of​ writing,​ my website contained a​ total of​ 53 pages.

Primary keyword phrase: “copywriter”

Average keyword density: Using the​ simple measure of​ keyword density discussed above,​ the​ average keyword density of​ my copywriting website is​ 1.9%. Using the​ complex measure it’s 4.9%.

Keyword density range: Using the​ simple measure,​ my density ranged from 0.4% to​ 7.6%. Using the​ complex measure it​ ranged from 1.6% to​ 17.5%

Some comments on​ the​ figures

• The figures and corresponding ranking detailed in​ this case study may not be directly relevant to​ every site. There’s a​ lot I don’t know about the​ algorithms and there are bound to​ be other factors at​ play which I don’t know about.

• With regard to​ Wayne Hurlbert’s article,​ it​ would seem that he is​ referring to​ keyword density as​ calculated using the​ simple method discussed above.

• The range figures are noteworthy because they suggest that you​ don’t need to​ be paranoid about having some pages with a​ very high density and some with a​ very low density.


A simple keyword density of​ 1.9% can be enough for a​ first page ranking in​ Google.com (assuming you​ have enough quality backlinks – see SEO for CEOs and How to​ Top Google by Writing Articles for more information).

Happy SEO writing!
