It looks like I was the first to post about the Baby Blizzard Bear. I even beat the Wow insider Post by a fraction, and to be honest I only posted it because given us Aussies ( and the Kiwi’s) have the advantage of datelines when it comes to dates ( but not TV networks, Wrath Releases and Movie releases) I knew that I would be one of the first to announce/get it out there – and thus I got some – and still am getting some extra Spiked traffic from Baby Blizzard Bear searches.
Whats interesting to note – as it was when my clicking on the Npc’s Post was linked via wow insider, that I did get alot more traffic on that particular post, but they didn’t stick around, or should I say “Click around” Posts like that tend to increase activity on my “About me” page too, and maybe a slight increase on posts around that one, but for the most these new vistors click that single post and leave.

Yup. I’ve never seen a permanent increase as a result of a WoWInsider link. You get a huge spike (which is thrilling) but traffic falls back to the same slope as before the spike.
