Is SEO enough to make a decent wage from affiliate marketing?

It’s now been a couple of years since I stumbled upon affiliate marketing and put up my first banners and text links.  In that time I haven’t made that much money from it but I have learnt a lot.  The biggest lesson I have learnt is that little site traffic equals little affiliate commissions, simple really.  You could also dumb that simple equation down even further, little effort equals little affiliate commissions but that got me thinking.

If I’ve managed to make pocket money from the very little traffic that I got from some of my early sites surely with more effort and hard work I could make more money?  That’s obvious I know but the way I see it many “would be” affiliates would have dropped out by now, difference is I enjoy it as well.

That leads me on to my question, is seo enough to make decent money from affiliate marketing?  I hope so is my answer.  I’ve been putting in a lot of effort to the seo of my recent site and have seen traffic steadily increase, fall of the planet (thanks google) and then steadily increase again.  This organic traffic is still very low but  I have made some affiliate sales and being in the travel vertical a single commission of £25 for one sale seems like a big deal at the moment.
