My blog has lots of links from technorati.com and their partners site, i thinks it is a reason for Google penguin penalty for my blog. It is true? You have any experience? Please discuss here....
I think it depends on you anchor texts as well. If you've overdone using keywords as anchor texts, then that could be the problem. Mind sharing us the percentage of your main keyword as anchor texts used? Just in my opinion, penguin is sensitive about using too much main keyword as anchor texts that's why I also used brand name and related long phrase keywords to diversify my anchor texts.
technorati.com not provide any anchor text, only links with website url... only links with anchor text create problem?
You mean the links you have in technorati are all URLs? hmmm that should not cause big problems... Btw, how old is your site and what was the last backlinks you've made before the drop? For keywords as anchor text, it's just my opinion that penguin is sensitive if main keyword are used too much as anchor texts. Because many of sites got hit by penguin, and those that did not drop got fewer links on them and have good anchor texts variations.
