I am loosing ranking for my keywords

I have three years of experience regarding search engine optimization, but I am facing a real tough time at the moment since I am loosing ranking for my important keywords. Even I am trying my level best to do quality link building but still I am loosing ranking. Any suggestion that how can I take control of my ranking in search engines.

 

Well.. Have you done anything recently for your rankings to drop? Or have you been doing something repetitive that used to work out for you but, is now possibly taking it's toll?

 

I think you are going in panda update.

Don't use copy writing content or black hat seo strategy.

 

You said you are doing Link Building, have you checked all the links that you have made in the past time, there is a possibility that those links might be removed. When it comes to link building making links on to related niche websites is very important other wise ranking can get hurt badly as new panda update has shown in past few months.

 

Extra dose of anything will also lead to spamming. So please be careful while any submission.
