website optimization is different from PPC advertisement. PPC really works for my clients and never tried for myself.

it depend if u got good budget then u can try ppc ,if not the result will be too small to make a different or u may consider cpm
PPC is great and it works.. but its more of like investing some money to make more money. You should give it a try and try diff campaigns. I have some information about it on my blog if you want to see how I did it.
It depends on what kind of website you have...if it's a content based website, don't spend money on PPC advertising!
I'm more for CPA offers than PPC. If your traffic is right and your optimize your offers you'll find much better returns.
