Sometimes it becomes very difficult to find out what the ads should be, i.e. specification of ads. I have seen people creating display ads greater than 50 kb size, ultimately of no use. So it’s better to know the specification before starting working on this.

There are two types of ads, they are-

1. Display ads
2. Search engine ads

The specifications for them are given below-

1.Display ads

File Type: .JPEG, .JPG, .PNG, .GIF

File Size: 50 kb or smaller

Supported File Sizes:

• Mobile leader board: 320 x 50
• Banner: 468 x 60
• Leader board: 728 x 90
• Square: 250 x 250
• Small Square: 200 x 200
• Large rectangle: 336 x 280
• Inline rectangle: 300 x 250
• Skyscraper: 120 x 600
• Wide skyscraper: 160 x 600
• Half-page: 300 x 600

In case of GIF ads –

• Animation length must be 30 seconds or shorter
• Animations can be looped, but the animations must stop after 30 seconds
• Animated GIF ads must be 5 fps or slower
• Animated GIFs cannot be used in mobile or tablet ads

2. Search engine ads

• Headline: Max 25 Characters including space
• Description Line 1 : Max 35 Characters including spaces
• Description Line 2 : Max 35 Characters including spaces
• Display URL : Max 35 Characters.

All ads should not –

• Use excess capitalization
• Use excess symbols
• Use incorrect grammar
• Use brand name

Hope this will help you.
