Ads can come from your competitors or ads might come from the same company selling the ad space. Regardless, all ads are competing for the same audience attention and your ad must be able to capture the audience's interest from all the other advertisements. Many web sites offer multiple slots where banner space can be purchased: top (generally the most expensive), down the left or right side, and bottom. If a banner ad is not placed on the top part of the screen, it is less likely to be noticed.
Even a one ad — a very long vertical banner ad occupying the side of a page — probably will never start at the very top of the page; sometimes users must scroll to see it. If you have the budget, you are still better off purchasing a banner that runs across the top of the page. If the screen real estate is not too cluttered, ask yourself how you can use your banner ad to catch a potential customer's attention.
Evaluate the colors on the web page on which you are purchasing space. Are you better off matching the colors of your banner with the colors of the site? You might not want your banner to communicate "blatant advertisement." Matching some of the colors in your banner can take off the edge. Or can you create a banner that uses different colors to catch peoples' eyes? High-contrast, bright colors for your banner background work well for attracting attention.
