Way back when I first started at University, I took an introduction to business class. The class was taught by a successful local hotelier. His message, if we didn't remember anything else from the class was that the four sources of wealth are Land, Labor, Capital and Entrepreneurial Ability. If you could remember that, and define them, you passed the midterm exam.
So, yes I know there are ads on my blog. Yes, I know the ads are sometimes annoying. No I am not getting rich from them, but there is some small reward.
If Blogger hosts your blog, on the content creation page is a link for adsense, it is not hard to sign up. I don't know if or how to invite ads on blogs hosted outside of Blogger, but I would guess there is a way. This is not a sponsored post, I know a few bloggers that occasionally are paid extra to write about products or services. Some of them clearly mark sponsored posts as such, some don't. I have never been asked to write a sponsored post, hint to the airlines - I can be bought with first class upgrades on transAtlantic flights.
Have you ever considered including ads on your blog?
