Google just recently updated its Pagerank and sadly, that update didn't went well for my blog. My page rank dropped back from 2 to zero. Sigh.
Doing those sponsored posts and a lot of other blog advertisements were maybe the cause of that PR drop but that won't stop me from doing it. I know Google hate seeing those "sponsored by" or "advertise on this blog" thingy but being a member of blog advertising networks and doing all those posts has been a big help not only to me but also to a lot of other bloggers out there.
I'm still glad though that my membership on the SocialSpark blog advertising network and on how I get sponsored posts from their advertisers is not based on Pagerank but on writing skills and good blog content.
Oh well, I hope I get lucky on the next update. For the meantime, I must the accept the fact.
"You have zero pagerank now Mark. Deal with it." Lol...
