Thanks for explaining what EMD means. In my opinion this Google's update is absolutely not fair. I hope that in a short time the results will get back to normal. Yes, there are spammers as well, but I think using the keyword e.g. "buy cars" in your domain name is rational if people can "buy cars" on your website.
Sorry dude, but I dont think they will ever go back to "normal" whatever that is. Did google ever go back after any other of the animal updates? Don't think so They need a form to submit sites that were wrongfully hit for review on a site by site basis or something
Same happened with me, now the thing is can anybody know how to overcome with this. Should I remove such keywords which should not match with any domain name?
The only way to overcome all these updates is to stop focusing on Google, switch to a different search engine and try to get everyone else to. What are they going to target next? Exact match title text? Image tags? Maybe they will decide all spammers use wordpress and launch the anti-wordpress update?
Yeah, I think you should wait until the serps settle and there is some data on this update and find different, more reliable traffic sources.
