Affiliate Marketing Secrets

let’s say the competition is kinda low. i’m talking about articles that use seo keywords for optimization. not in articles websites but in regular websites in the same niche as the blog. are ten enough to bring halfway decent traffic and help with location in google?
and how many articles should one put in the blog itself, is one enough?

I have been selling my designs (household products) on my website for the last 3 years. I have had these products made in China in the past but my existing supplier has now ceased trading. I do not wish to continue starting from scratch with another chinese firm and considered closing down business. But I still have a valuable site which has had extensive SEO investment and ranks in the top 5 pages on google for several keywords and we still get decent traffic daily. Rather than let the site go to waste I was considering selling other companies products through an affiliate program which looks like a genuine e-commerce site rather than a ‘trashy pay per click’ link-redirect site which sends people to other companies sites. Does anyone know of a good affiliate scheme that allows businesses to select and choose products and sell whilst using the suppliers e-commerce software or source code to embed into the our website.
Any advice will be much appreciated.
Thanks in Advance!

i recently made a website and currently under construction but its going to have links to many affiliated sites. about 10. so how much income does the average person make by doing this? would i eventually be able to make a few hundred dollars a month within the next 3-4 months if i get decent traffic?
