Online advertising specifications
Our site incorporates ‘responsive’ designs. It can detect the device on which it is being displayed, whether desktop PC, tablet or mobile, and render with the size, layout and resolution that makes it easiest-to-read.
It is very important that the size of online advertisement files match industry standards. The accepted current industry standard is set by the Interactive Advertising Bureau. The IAB Ad Unit Guidelines are intended for marketers, agencies and media companies for use in the creating, planning, buying and selling of interactive marketing and advertising. This standard is applied by nearly every media company in the world. The following guidelines apply to material created by Mercator or supplied by clients or agencies.
