A slightly less well-known method of monetization that is only offered through a few advertising networks. It involves adding a text ad overlay to the images on your website when a user hovers over them.

For example, if you've recently written an article about the best hotels to stay at in Amsterdam, you could monetize the images within the post by allowing advertisers to have their ad displayed when a user hovers over them - this would be relevant to the image, of course.

One advertising network that offers this is Reachli, and they have a great video on their site explaining this in more detail.

Advantages: This is another method that takes very little time to set up and can be easily run in conjunction with other monetization techniques. Also, like with in-text advertising, if you're publishing a lot of fresh content on your blog on a regular basis (i.e. multiple times a day) then you can see a good return from it.

Disadvantages: One major disadvantage when using in-image advertising is that you don't have a say on the partners that will be advertising on your site.

Alongside this, it can end up looking quite spammy and mean that you could potentially lose out on social shares of your images via the likes of Pinterest/Instagram.
