"Total HTML Similarity" is always about 95% or more. (I am using wordpress). I am wondering how I can reduce this number.
I remember reading at SEOmoz | YouMoz - A User Generated Search Industry Blog
|Here at SEOmoz, our PRO platform uses a 95% threshold to judge duplicate content. This means if 95% of all the code on your page matches another page, then it's flagged as a duplicate. To check your own ratios, try this nifty duplicate content tool.|
