Hi Sunil,
Mobile business is a very broad category of which there are many things from mobile sites, apps, games, services and products etc... Perhaps you want to get into development or sales? Its not clear where your focus is... as well as your core business... If you are looking for specific help then please let us know more.... If its just extending your site to that of a mobile version then in my opinion that's likely not to do much, especially as smart phones do a great job of displaying standard sites...
If its selling stuff - my personal view is that it needs to be focused towards mobile specific or benefits arising from use of mobile i.e. searching for geo info whilst on the go, bookings etc... I've learned the hard way on Adwords and for the vast majority of stuff my ads will not appear on smart phones... I see a lot of people clicking on ads but never making the purchase - for me that amounts to 50% loss and now I seriously think twice before placing ads for mobile...
I've asked a lot of my friends and family what they buy on mobile devices - and for the main part its apps/games... I know its a big market - but my current thinking is that only certain/specific things are working.... I personally don't buy anything on my smart phone, I've only ever purchased whatsapp lol - and for the main part I would rather wait to getting home and buying on my laptop.... and I know a lot of people are like that.... perhaps even the vast majority as I suspect....
So if I was you I would conduct some market research and try to figure out if your direction is worth pursuing before investing serious money/efforts etc into it...
Best of Luck,
Sid
