This has been my go-to strategy for the last year or two. Making tables that summarize product features and ratings allows visitors to your website to compare reviewed products easily. In the product tables I make, I include product images, product rating, price, pros and cons, and a buy button with an affiliate link. Be sure that your table is mobile-friendly so that visitors on phones and tablets will be able to view your content. Some good WordPress plug-ins to use for creating tables include TablePress, TableLabs, GoPricing and Ninja Tables.
Now, truth be told, affiliate marketing does come with some costs. Fortunately, those costs are rather small when compared to starting other businesses. For example, if you want to succeed with affiliate marketing in the same way that I teach it, you’ll need a website. In order to have a website, you need to pay for “website hosting”. If you don’t know what website hosting is, don’t worry, we’ll get to that, but website hosting does cost a few bucks per month (generally under $10 / mo). If you have about $40 for startup costs and about $10 / mo for recurring expenses, this is entirely doable. There are many other optional expenses for affiliate marketing, which I will also get into, but those optional expenses are used more for speeding up the path to success (outsourcing, etc.) rather than a requirement for success. When I first started my affiliate marketing business, I had about $200 to my name.
