It is probable that advertisers and media industry will increasingly take account of a bigger and fast-growing mobile market, though it remains at around 1% of global advertising spend. Mobile media is evolving rapidly and while mobile phones will continue to be the mainstay, it is not clear whether mobile phones based on cellular backhaul or smartphones based on WiFi hot spot or WiMAX hot zone will also strengthen. However, such is the emergence of this form of advertising, that there is now a dedicated global awards ceremony organised every year by Visiongain.
As mobile phones outnumber TV sets by over 2 to 1, and internet users by nearly 3 to 1, and the total laptop and desktop PC population by over 4 to 1, advertisers in many markets have recently rushed to this media. In Spain 75% of mobile phone owners receive ads, in France 62% and in Japan 54%. More remarkably as mobile advertising matures, like in the most advanced markets, the user involvement also matures. In Japan today, already 44% of mobile phone owners click on ads they receive on their phones.
Types of mobile ads
In some markets, this type of advertising is most commonly seen as a Mobile Web Banner (top of page) or Mobile Web Poster (bottom of page banner), while in others, it is dominated by SMS advertising (which has been estimated at over 90% of mobile marketing revenue worldwide). Other forms include MMS advertising, advertising within mobile games and mobile videos, during mobile TV receipt, full-screen interstices, which appear while a requested item of mobile content or mobile web page is loading up, and audio advertisements that can take the form of a jingle before a voicemail recording, or an audio recording played while interacting with a telephone-based service such as movie ticketing or directory assistance.
The Mobile Marketing Association has published mobile advertising guidelines, but it is difficult to keep such guidelines current in such a fast-developing area.
The effectiveness of a mobile ad campaign can be measured in a variety of ways. The main measurements are impressions (views) and click-through rates. Additional measurements include conversion rates, such as, click-to-call rates and other degrees of interactive measurement.
Handsets display and corresponding ad images
There are hundreds of handsets in the market and they differ by screen size and supported technologies (e.g. MMS, WAP 2.0). For color images, typically PNG, JPG, GIF and BMP, with WBMP being the most basic (and the most common). The following gives an overview of various handset screen sizes and a recommended image size for each type.
