Always make affiliate links nofollow. Google’s goal is to provide its users with the best possible search results to their search queries. One of the main ways they figure out which webpages are the best is through links. The Google bots crawl the web, reading text. When they come to a link, it’s like an open door. They follow the link (walk through the door) and explore the site you linked to.
Create a website. In order to work as an affiliate marketer, you'll need your own platform (a personal website or blog) on which to post links and advertise for your chosen products or services. If you already have a website or blog, you can use that platform to begin earning additional income as an affiliate marketer. If you do not yet have a website or blog, you will need to create one.
If you’re a blogger, start by going through your analytics and finding your most popular posts. In Google Analytics (GA) you can find these pages by going to your GA Dashboard > Behavior > Site Content > All Pages. Examine the ones at the top of the list that bring in the most traffic. Are there any affiliate products or services you can naturally include in them?
Always disclose your affiliate relationship. Most visitors will probably understand that graphic ads will lead to your getting paid, but if you write a review or use an in-text link as a recommendation, you want your readers to know that may lead to compensation as well. This ensures you retain transparency and trust with your readers, but also, it's required by the FTC's endorsement rules.
