SEO Experiment - January Update

Aside from a mention or two around the time of the last page rank update, I've not looked at the SEO Experiment results since December, as part of my quest to see if target="_blank" could damage / hinder link building efforts.

Site 1 - (no links in, 16 posts). 17 pages cached in Google, although the home page and 1 archive don't actually return any cached results. The other archives were cached 17 & 32 days ago, the posts 7 X 12 days, 1 X 13 days, 1 X 17 days, 1 X 34 and 3 X 37 days ago.

Site 2 - (links without target, 17 posts). 19 pages cached - home page 7 days ago and the archives 5 days, 2 X 11 days and 12 days ago. The posts were cached 5 X 5 days, 7, 2 X 8 days, 10, 11, 3 X 12 and 13 days ago.

Site 13 - (links with target, 17 posts). Manages 20 pages cached - home page 4 days ago and for the archives, one was 9 days ago and the other 3 were 12 days ago. The posts were archived 5, 6, 9, 2 X 10, 2 X 11 and 8 X 12 days ago.

There is a very noticeable difference there - the average site 2 page was cached 8½ days ago, the average site 3 page 10½ days ago. For site 1, the average is 20½ days since last cached!

Next time I'll take a look how the sites have their page ranks distributed. But given that the sites are near enough being treated the same, there is a noticeable difference between the sites.
