All banners must be supplied in GIF file format at a size of 470x70 pixels. All ads that are not 470x70 will be anamorphically scaled to 470x70 on the fly. Also, all ads must be no greater than 8,192 bytes in filesize. In addition to this, a single sentence of alternate text of not more than 50 characters should be included with your ad. Ads not adhering to these few guidelines will not be implemented until all issues are resolved.
All ads appear at the top of the page.
This offers the most effective method of generating a response by placing the ad before any other content. Ads are also centered on the page and have a blank line inserted between them and the content of the page. We don't try to spread ads out all over pages of an overly complex site, we just focus on those pages in our system which we feel get the most traffic. If we find that certain other pages are becoming more popular as time goes by, we might decide to put them into the rotation as well. That's right, we have a limited number of spots where we can insert your ad into several very popular sites as well as The CompuMarket Classifieds .
