A custom designed banner by an expert designer will have an original design and custom size. You can ask for a static or animated banner to your designer. Cost should not be an issue as a good banner designer will charge you a market competitive price for his standard output.

Free banners and cheaply designed banners lack creativity and originality. Their color, font and size are tough to modify. Also free banners take more size on web server, so pages take more time to get loaded.

According to specifications of IAB, banners come with specific sizes. Banner sizes depend on where in a web page they are placed. Besides standard banner sizes there can be custom banner sizes for each banner.

Success with banners depends on banner sizes, text content, illustration, color and font selection, etc. Repeated exposure in front of your customers makes banner advertising a great success.
