Blog and content websites are totally different but adsense can be used in both niche... It would be better if you had described in what point you are confused...so we could have given you right answer
Means in both we choose a niche and start writing about it then whats the difference. The only difference i know about it is that blogs are more personal and content sites just give info. What else?
If the goal is to make money, then there is little difference between blogs and content/article websites. Obviously, some foks blog or post articles online simply to share information or their opinion. However, if the point is to publish content and earn money from traffic and ad revenue, then you could use either. From my point of view, blog software is better suited for content that is current, topical and changes in cycles. Articles and content management systems are better for articles that are permanent resources of information that remain valid over time. The difference is implied but not strictly adhered to. I've seen examples of blog users posting more "article" type information and article writers using "blog" software. I'm not sure if the difference matters to the users OR the search engines, but it probably doesn't have a big effect.
