Experiment 1.

The results of this experiment first became visible on 12/10/2011.


The Hypothesis:

That a keyword density of around 2% was perfect for SEO.

The tools:

Blogger to create blogs with varying keyword density of a specific character which will not be repeated anywhere, SEO Quake Toolbar to measure the Keyword Density of the blogs and google to measure which density ranks higher.

No backlinking will be done - the content will be identically nonsensical, and won't be promoted anywhere - it will be a pure content only test.

The First Result:-

Having created the following blogs:-

The art of x453gogjf94rturdrfglrkto [Keyword Density: 1.95 % (359 words)]

The Method of x453gogjf94rturdrfglrkto [Keyword Density: 4.86% (370 words)]

The google rankings of these blogs are as follows (On 12/10/2011)


#1 The Method of x453gogjf94rturdrfglrkto [Created 29th Sep 2011-2:09]

#2 The art of x453gogjf94rturdrfglrkto [Created 29th Sep 2011-1:49]

So here we can see one of two possibilities - being created slightly earlier gives 'The Method' slightly more authority and relevance (unlikely).  Or the Keyword Density of 4.86% trumps the Keyword Density of 1.95%

The question that remains is - does a higher Keyword Density than 4.86% give more relevance and authority or does it start to look spammy?

To test this I have created the 'Master of x453gogjf94rturdrfglrkto' blog with 332 words and a 6.93% density.

There are several more tests to be done - it could be that rankings are based on mentions, but high density flags a site as spammy.  Once I've ran this test - I will write a much longer blog with a slightly less than optimal density but with a massive number of repeats - to see where that site gets placed.

Interestingly my main site for promotion, because it targets portable air conditioning and portable air conditioners has the highest density for portable air yet it doesn't rank at all?  I've tried making a contextual link with that keyword - now we'll see if that has tipped the balance to make it index.
