Powered by Commission Junction, TripAdvisor's affiliate program pays a 50% commission off the revenue generated from a user clicking on links and/or ads that send them to a TripAdvisor partner site. Which means, unlike most other affiliate programs in this list, you don't have to wait for your referral to make a purchase to earn your commission. As soon as someone comes from your website and clicks on one of the ads or links on the TripAdvisor website, you get paid.
This is another thing that affiliate marketing beginners need to be aware of. Affiliate marketing is not limited to blogging and social media. You can actually do it using email. However, the challenges that you face here are more or less similar to the ones that you face when it comes to blogging. Without a big audience, you are probably not going to be able to make it work. Anyway, there are many ways of increasing your mailing list. You can use your blog, as an example, to offer freebies to those that are willing to sign up for your newsletter.
