Hope to hear from you guys..

Looking at those signatures, I'd say the OP's favorite is spam bots.

Well buddy i am not getting the idea. Plz let me clear your question.

I am a frigging sig spammer! Look at my signature!

For me SEO is the the best marketing tool. I promote website through it.

There is a similarity on OP's signature and the other person who replied. Both URL's starts with "easy".

Anyways when it comes to online marketing there is no best. Usually there will be 3 or 4 that will work best for you. Blog commenting and Article marketing work wonders to some but maybe not for everybody.
