Hi guys. I try to rank a web (EMD) for keyword that receive around 643k monthly search (data from keyword planner). Currently I'm ranking on 4-5th place. Couple days ago I just bought web 2.0 backlink from xxx for $17. Today I check my ranking drop from 4th place to 83 in Google.com My curiosity goes to a web that use exact domain like me except its have "-" for the domain. Eg: mine abcd.com, while the domain ab-cd.com It seems like it takes my position for the 4th place.
