I have a friend and he is selling products on ebay. He did make a lot of cash but I want to earn too. My plan is to create a site (wordpress) and I will post his products on my site as a ebay affiliate. Later on I will add adsense in future. My question is what is the best plugin for this? Any advice and suggestions? Sorry if my English is bad. I hope this makes sense.
A couple of years ago, the clear answer was phpBay. Great tool with a solid community following it. Unfortunately, it hasn't been maintained in a couple of years now, so I'm not sure if it will still work for you. A popular and more modern option would be the Auto Affiliate Links plugin in the WordPress directory. It supports a bunch of different affiliate networks, but you can just restrict it to eBay if that's what you're focusing on.
