In my opinion a successful ad is something that you can relate to. It also needs to be something that you can understand right away without having to think about it for too long. It should have short words that aren't complicated and they should be in a large font. Also the ad should be in bright, eye-catching colors.

Successful:

This ad is successful because it is red, which is a very 

eye-catching color. It is easy to see what is being advertised. The words are in a font that is easy to read and they are two, simple words. This ad makes you want to see if the coke is really as good as the ad says it is. We can all relate to happiness, because it is something wet have all felt.

Unsuccessful: 
                            

This ad is unsuccessful because it is unsuccessful because it has very small text and it is unclear what is being advertised. When you first look at the ad it is not easy to see right away why there is an eye. The colors do not grab your attention right away.
