This monetization method involves adding in affiliate banners or widgets within your content (in a contextual manner). This is very similar to the text affiliate ads but with this method, the affiliate links are a lot more visible and often include an offer within them. An example would be within my review of Sprout Social's social media management software.
Advantages: If you can make sure that the banners are relevant then you can make some good income this way. An advantage to using an affiliate banner over a text link is that it is a little more transparent that you are promoting something, as opposed to the text links that can sometimes be seen as you 'deceiving' readers.
Another advantage of using affiliate banners are that you have control over what banners you publish - within the fashion niche, these banners are used to great effect and can actually add to the design of your website.
Disadvantages: Like I mentioned before, having affiliate banners makes it clear that you are trying to make money from your content. This can put readers off, especially if it's not in context. This can also cause a few issues when getting people to share/link to your articles and can sometimes reduce readability.
