I am planning to make revenue from my startup purely from affiliate agreements/ advertising. Is google adwords the best advertising option available on a site? which affiliate programs are best, are there popular ones i should stay clear of?
That's a great question! If your budget aligns with a PPC setup I say go for it.
If you're looking for more organic and economical options I'd recommend using social med Facebook, Twitter and LinkedIn.
The best type of marketing content is going to be video, picture 2nd and content last. If you do decide to go the Adwords direction I've got some people who can help you with that.
