While your site is still new, it's a good idea to start capitalizing on someone else's audience. Continue focusing on building your own content, but also considering writing content for a few big, high-traffic blogs that are relevant for your niche. By writing content for a bigger site, you are able to get in front of another audience and showcase your expertise on a particular topic. This will eventually lead to more traffic to your site, as well.
However, be aware that you need to submit an application to most of these networks to be accepted. Once you're accepted in, you're often required to apply directly to the merchant afterwards. So there are two layers or gates that you need to bypass. That's also why it's important to build up your platform and create that emotional bridge between yourself and your audience before attempting to promote anything to them.
I built several small sites that only sell ‘small’ items for sale on Amazon. Typically $4/$5 an item, and items that are usually bought in bulk. Painting supplies, for instance. I then take out a small Facebook ad at the start of the month promoting that site. Usually 2 or 3 orders of multiple products is enough to send my commision percentage up, then it’ll stay that way until the end of the month. Hope that helps someone. 🙂
Banner and sidebar ads: Virtually every affiliate program provides a wide variety of ads that you can insert into the sidebars, header and footer sections of your WordPress website. Some of these affiliate ads promote a flat-fee product like the Amazon Prime free trial. Others automatically update with features products and items from your affiliate partner. Either way, if your reader clicks on one and makes a purchase, you get paid.
