Banners are basically pictures that represent your webpage, which when clicked on, take the user to your website. They come in various standard sizes to fit in good locations on sites and some people believe that banner ads are more effective than text ads.

You can place your own logo, site theme, or use custom text styles on your promotional banners. Due to their high visibility, appearance and site identity, banners will attract more traffic which ultimately will improve your site conversion rates.
The second important factor is banner position. You have to get a good position to place your banners to ensure you are rewarded with effective targeted traffic. So to sum up, if you have a good banner and good site placement then banner advertising is a very effective type of promotion.
