Mobile advertisement is actually booming online throughout the internet network. The impact overall is more focused to two categories of mobile advertisement:
1) Push Based SMS adverts
2) Online WAP Based Adverts (Like Admob, Google Adsense Mobile)
While Push based SMS adverts are kinda intruding because I am pretty sure that most people do not want to get them but it does have its advantages. Out of an 100 SMS, stats say that only 30 are being immediately deleted by the consumers and the rest of the 70 are being stored in the memory (Thanks to almost unlimited storage and the overall easy portability of SMS into PCs) which are usually always there in the memory card or inbox of the end users. With them being already there means the consumers knows that they have the information is there somewhere in the inbox and when they need it, they can easily fetch it right back. Hence more of the traditional push based marketing are still being done through Push SMS. It mainly includes the discounts of several shops, movies, etc.
However, in my honest opinion, the more effective medium for advertisement through mobile is what admob or google adsense is currently doing. They are showing relevant context based ads on top or bottom or both. This does provide a cheaper rate per client served and it also ensures that they are not intrusive (as usually they are all text based advertisements) for the client. While Adsense does ensure the publisher better quality of ads served, Admob does not by default. Admob provides you with relevant ads (almost relevant) but they will often include adult text ads which might get a little uggghh for any publisher. Anyway, what I was trying to say is that though Push based SMS advertising/promotion ensures a point of reference for the end users, they are still not worth the return when compared to the relevant text ads. It builds brand awareness, the market is not saturated either so you will get a fair price/impression and most importantly you can geo-target your impressions to the extent one might not even imagine at times lol.
Also, like Camilla said (....Hi Camilla, nice to meet ya!), there are new things popping up everywhere. While I personally am now really interested to know how exactly that particular mode of advertisement works, on what reference or do they have to install anything or not, but I am also venturing out to better evaluate a new mode of advertising model which is sponsored applications or games. I am sure many of you have heard or experienced it already but for the ones who still didn't, here it is in a nutshell: A developer have the potential to develop a game or application but does not have fund they might need to develop it or market it. So he or she simply looks for an sponsor (or sponsors) who will finance/market/blah blah everything he/she needs to develop the game (or application) and finish it. Then they will integrate ads with that game/application which will pop up every time the end users who will be playing the game launches it in their mobile phone. Traditionally, they are all free games or applications which gives them a better leverage in terms of exposure if marketed right! This apparently ensures your brand reaching a targeted niche and also gives the advertiser's ads to get an unlimited number of impression at a fixed cost.
Anyway, who am I? Well I am a blogger and certified developer of the UI of the symbian mobile platform and I am also a mobile marketing and mobile SEO enthusiast who is just trying his best. I also have experience in serving the biggest telecommunication provider in our country namely Bangladesh. Nowadays I am working as an assistant manager in one of the fastest growing content developer in our country where I am mainly responsible for the "creative side" or product marketing and stuff like that. Last but certainly not the least, Hello everyone! Awesome convo btw!
