What will be my profession in my income tax file?

Hi, 

I have two websites, one is a "Job Portal" and other one is a "Classified portal". Both websites are free to users and I am running Adsense Ad on those. Recently my income through Google Adsense programme  is increased and is almost 6lakhs per year. Therefore I am planning to pay my Income tax (Week ago i received my new PAN card) but I am little bit confuse on my 'profession' type -

I want to show my Adsense income as "Income through Profession" so that I can deduct my expenses like website hosting expenses and etc, but I am confuse what will be my Profession. I mean what profession shall I mention in my file? Beside those two websites, I have no any other business and no any other source of income.

Please suggest, on what type of profession I fall what will be best to introduce myself to income taxwala. 

Thanks.
