Should I go for media buying or SEO?

From what I know about CPA networks, if you are just starting in Internet Marketing, you might have difficult times to getting approved on their network. They've become very picky along the years. I'd suggest you start with standard affiliate marketing of high quality products, to build yourself authority and credibility, and then go for CPA networks. That said, it does not mean you cannot be approved otherwise, but it can be hard.

As per the best traffic method, the best traffic method is the one that would best fit you, your model, your funnel, your budget, your goals etc... they're all different and could be used for different reasons, but one should not be left without the other one necessarily.

I would always suggest that one goes for the long terms in building traffic, that goes along with Authority and Credibility, but to start with if one is in a hurry with cash one can go with the different paid traffic methods.

Media buys for quick results (costs money)
SEO for long term [eventually] passive results (could be done with 0 budget, to some extent).

Paid traffic all the way, SEO is ever changing and takes usually a long while to get results, especially in your niches.

If you want to earn results faster, do media buys or any paid traffic for that matter. However, SEO is cost-effective and better for long term results. You can do both techniques

Why not do both.


Start an SEO campaign (which will take a LOT of time in those niches) and also buy some traffic.


The more you learn about each one of those, the better marketer you will become down the line.
