Affiliate networks offer you access to multiple (and by multiple, we mean hundreds if not thousands) of individual affiliate programs. They basically work by simplifying the signup process - instead of applying to become an affiliate for a each product you want to promote, you simply apply to join the network and instantly have access to hundreds of different affiliate offers.
Find a program — As we discussed earlier, many affiliate marketers find their merchants, vendors, or brands through affiliate programs. It’s important you determine your niche prior to finding a program, as some programs are geared toward certain types of products. If you’re interested in a particular affiliate program, look into what kinds of products it offers and whether it has any data on the success of its affiliates.
If you want to uncover more merchants who partner directly with affiliates, just keep your eyes open. When you see affiliate links, do a quick search to see if the related merchant runs their own program. (We came up with the list above by reviewing a few of the bigger affiliate marketing blogs and investigating the most prominent affiliate links on those sites.)
SkimLinks works very similarly to VigLinks in that it is designed for bloggers who don’t want to do a lot of hands-on work to participate in an affiliate program. SkimLinks also works much like VigLinks in that it uses a plugin or script to create dynamic links in your content to send visitors to higher paying offers from merchants. SkimLinks claims to work with over 24,000 merchants/advertisers.
