I think a good advertisement is one that has a hook to catch a person's attention. perhaps a funny statement or a touching photo but something to draw people in. I also think a good advertisement should have enough information to distinguish it from other products so that the reader will think that its is the best product. In my opinion, a bad advertisement is one that has way too much text because I personally would not care to read about it or one that would make the viewer feel bad about his or herself.

to me this is a bad ad because the logo is too small it is hard to understand the photo 

 this a good advertisement because it provides information to distinguish this company from its competition
