In effect, VigLink works as the middleman between a publisher (blogger) and merchants by scanning the publisher’s content and automatically creating links to publishers that are chosen “in real time” based on their payout/conversation rates. This makes VigLink a very hands-off affiliate program for publishers who prefer to focus on content instead of managing their affiliate links.
Who is your audience? What is your target market or niche? If you're targeting a specific niche like home security then perhaps you only need to sign up to ADT and SpyBase so your products match your audience. There’s no point promoting eco-mattresses to your blog that’s focused on reviewing drones. Again, you could sign up to a network that has a few different options in your field of interest or just go straight to your favourite suppliers and see if they have an affiliate program.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
