I use to have very good ranking for my website, now I'm struggling with ranking, I've been trying almost everything, I purchased an advance link building, a contextual link building campaign with Submit, and doesn't seem to be working.

Any recommendations!

I assume you have checked Google Web Master Tools for any warnings/messages?

and did you buy a load of cheap links and guest posts....
