I talked about blog sponsorship above, but this monetization method involves allowing the sponsorship of specific category pages on the blog or certain columns that are written.

Lots of major news websites offer this kind of advertising because it allows advertisers to market only to the readers interested in the types of content related to their business.

Advantages: If you run a few different columns/categories across your blog then this gives you a way of squeezing even more revenue out of sponsorship, and can even be run alongside a full blog sponsor.

As well as this, you'll be able to deliver more relevant traffic to your advertisers which should deliver a better return on investment for them.

Disadvantages: The main one here is that if all of your different category pages are sponsored by a load of different companies then it could dilute your blog's brand. Alongside this, it might start to look a little over-commercialised and it could compromise your design.

I'd only really recommend this if your blog is a large news-based website that covers a broad selection of different topics.
