COSTS: General conventions of magazine adverts

General conventions of magazine adverts 
As adverts vary in size so does the price, the bigger the advert the larger the cost.
The whereabouts of the advert is also vital to its price as if it is printed on the inside of the back or front page it is at its most pricy. Another thing to consider is what our main target audience is and which magazine genre would be most suited to publicising our artist. However it is also a good idea to place smaller adds in alternative magazines to appeal to a secondary audience.
A good website to check out costs of placing adverts in magazines is Small businesses.
It states that 

at the time of publication, a national woman's lifestyle magazine charged nearly $250,000 for a full-page ad while a niche gardening magazine only charged about $10,000.

Positioning
Inside the front cover, inside the back cover and the back cover are prime advertising spaces. A West Coast magazine at the time of publication charged $141,800 for the inside front cover, for example, while a full-page ad cost $118,400. Advertising toward the front of the magazine costs more than toward the back of the magazine, with the exception of the back cover. The magazine may demand that the ads towards the front are a minimum size, perhaps full or half-page only.
