Conventions of a magazine cover:
Direct Address- the main image attracts the audience as it is very sexual, this intrigues the reader to see more inside. The target market is men and publishing a picture the 'hottest girl on tv' will definitely attract men.
"ohhhh my God!" is very chatty and informal, this relates to the reader as the magazine isn't too formal, By making it chatty it...
Advice/tips- "How to work smarter", "mans guide to love (&sex)".
Why?- these target the audience as if a man is looking for love, maybe even sex he will be intrigued by the cover line. Also if someone was looking to be higher in their job or get a pay-rise then "how to work smarter" will be interested.
