"The forum folks at DigitalPoint are discussing what is the best keyword density for your AdSense ads to show the most relevant ads.  Some member say you want at least a total \"around 200 words with a 4% density\" to get the most relevant ads.  And here is a quote from page two. go for 4% but not from the get go. I kind of work my way up there. The problem is, it could take anywhere from 2 days to 2 weeks for the change to take effect. To complicate matters a change may take effect very quickly within a few hours only to return to the original in a day or two! So you need to monitor it carefully.Also, in my opinion the mediapartners bot prefers to \u201Csee\u201D a couple of keyphrases so I always target say \u201Cstriped blue widgets\u201D 2.5%, \u201Cblue widgets\u201D by itself around 3.5% and 1% or so of \u201Cblue striped widgets\u201D while all the time target is really \u201Cblue widgets\u201D.Note that the above densities are not cumulative. Total \u201Cblue widgets\u201D density never exceeds 4%Talk about watching AdSense like a hawk. :)"^^<http://www.w3.org/2001/XMLSchema#string>
