So i had purchased 3 different services from the BST one was a citation service, and the second and third were diversity services which included web 2.0's, articles, and etc. About 4 days ago i noticed my rankings dropping severely. All the keywords containing terms which i used as anchors have dropped. The services were from highly reputable members and i KNOW that they shouldn't have harmed my rankings. Link building has always been consistent on my domain and no risky seo has been done on this site. I've seen dancing before but this is just scary! I have checked web master tools and no manual actions have been found. I know everyone is assuming google rolled out an algo update but when i was reading posts regarding the update many members claimed to see a serp rise and only a very small few saw a decrease in rankings. What are your thoughts? PS: The keywords that are up DO NOT CONTAIN THE KEYWORDS USED WITHIN THE ANCHORS we created links for!
