Rotate your animated banner ad at a relaxed speed.
A good online banner design will not be something that flashes a thousand times a minute or jumps, runs or hops across the screen as soon as the web page opens up. That will only serve to annoy your potential customers. Instead a successful animated banner should be tastefully done with frames rotating at a medium speed.

Make sure it downloads fast.
Sometimes potential customers don't wait for an entire page to download before they move on. It is important that you create an animated banner design that downloads fast, so that potential customers will actually see it before they move to another web page.

Put your most important information first.
Because you will only have a reader's attention for 3 seconds or less, it is important to grab their attention and give them your information fast. Be sure you put your most relevant information in the first few frames of your animated custom web banner.
