You should consider creating a single product review or product comparison review. Instead of just mentioning the product features, it does help if you have the product or use the service. These types of review videos where you have the product, as you explain, usually attract many views. 

This video content style involves you as a creator opening up a package and then sharing the product's features and your experience. You don't have to buy every product you review. If you ask nicely, most companies are willing to give out their products in exchange for a positive review.

How-to videos are informative video content that shows the audience how to do something the right way while recommending products that make the activity easy. You should try as much as possible to demonstrate how the product works. Consumers love social proof videos, and this singular demonstration may drive your affiliate marketing conversions through the roof.

These are roundup video reviews of different products. To earn from this type of video content, you need to be an authority on the subject matter. This way, whatever verdict you give or whichever product you rank as the best, your audience will value your opinion. Several YouTube video content creators use this video format to promote their Amazon affiliate links. 

You should always place your affiliate links in the description. This way your viewer does not miss it, and you should also encourage them to check your description at some point in your video. You can mention it multiple times if possible.

In addition to including your links in your descriptions, you should use YouTube Cards. You can find these non-intrusive notifications at the top-right corner of the YouTube video player.

You should use YouTube End Screens. You can find these in the final 19 seconds of your video.
