SEO is considered long term, only if you DON'T understand algorithms updates, google and new world order SEO
PPC is considered a fast solution, when you DON't know what proxies, VM, VPS, and T&C's are.
Wherever you go, there is money to be made and chests full of gold are waiting

Only that you need to swim,dive,drive a sub, empty the sea. Different roads, same path
