In order to continue the experiment, it seems that our pages are now indexed
testacatstring - Google Search
Page3 is listed before page4 ( I actually think its because when I calculated the density of keywords I did not consider single letters, and page3 has in this way less characters ).
Anyway, we can go on further with the experiment, I will try to create a flash button with link for page4 ( because its listed behind page3) and if these flash links pass trust, page4 will be placed higher.
