1. Consider the audience who would read the magazine
Make sure it reflects the ideals of the reader and suits the magazine.

2. Consider the Resolution
Magazine ads are often printed on high end gloss paper. Make sure to use a resolution of at least 150 dpi (300 dpi is ideal) for a crisp imagery and text
3. Use space well
Make use of all available space, either through using colors, pictures or lettering.
This doesn't mean make the ad busy, but consider white space in the overall design
4. Be Clear. Start Simple
It should also be very clear in what it is offering, so be sure to make the message of the advertisement is the central focus.
Begin simple. Some of the best advertisements are very simple designs with a strong message.
Try a single, commanding message or image in the center of your advertisement or consider a double page ad
Remember: the concept comes first, design is second.
Newspaper subscription (printed) has gone down considerably. Yet, advertising in newspaper is still very much alive.
