What are the button advertisements in the advertisement?

Button advertising is a small advertising form, and there are two main reasons for its development. On the one hand, it can reduce the purchase cost by reducing the area, so that advertisers with little budget can afford to buy. On the other hand, it can make better use of the scattered blank space in a relatively small area on the web page. There are 125× 125× 65438 common button advertisements in life. There are four sizes: 120×60 and 88×3 1. When making a purchase, advertisers can also buy several button advertisements in consecutive positions to form two-button advertisements and three-button advertisements to enhance the publicity effect. Button ads are generally small in size, and there are three common formats: JPEG, GIF and Flash.
