A banner ad is basically a graphic, text or an image displayed on websites that aim to promote a company’s product or service. They are actually small HTML codes, but their importance in internet marketing and business is significant. Banner ads vary in sizes and orientation but will often come in rectangular shape and are 486 x 60 pixels high (full banner). There is actually no universal rule when it comes to banner ad file sizes, but the size will still depend on the website where it will be displayed. These sites impose certain limits to banner sizes since it adds up to the total size of the web page they are displayed on, thereby resulting to more waiting times while the page loads on a browser.
Due to the banner ads’ graphic elements, you may find these ads somehow similar to those you see in printed media such as magazines and newspapers. However, these banner ads have the ability to direct the user to the advertiser’s main web page. If you are interested in displaying or posting a banner on a certain website, you can arrange with the publisher to have your banner posted or pay a banner network to post the ad on a number of websites. You may also arrange with the publisher to simply display their ads on your site in exchange for them displaying your banner ads.
