Many bloggers are making their blogs multi-author blogs these days. In this way they are inviting guest authors to write articles for their blogs. This is a best idea for one to show their creativity on most reputed blogs and it also gives a link back to the author of the article. If you are also going to start guest blogging on your blog, I’ll suggest you to start a revenue sharing program.
In revenue sharing program, author of the article can use his/her own ads along with his article. This will attract more guest bloggers for your blog. And if you are using WordPress you can automatically rotate ads based on the author of the article using a wordpress plugin called as AdShare.
AdShare will auomatically roate ads based on the author of the current post. Once installed, you can assign Adsense IDs to each author from settings page of AdShare.
