Hi Soubaghya Das,
To Increase your adsense revenue you must really work hard. If you have your own blog then please post content to it regularly. And also as you have an ISC account, you can contribute there more to earn more.
In ISC concentrate more on Bookmarks, Resources, Question Papers, Schools and Colleges, Business Directory, Reviews and ask experts. By Contributing more to these sections you can even earn cash credits (except in bookmarks, colleges and schools) and also you will be able to generate more cash credits.
In Mybengaluru also concentrate on Resources, Bookmarks and Business directory to earn more. Hope you may get more adsense revenue from these sections. These suggestions are from the experience of ISC and not from the experience of MyBengaluru because MyBengaluru is not yet officially announced and I have not been active in any of the sections suggested by me.
All the Best for your future journey in Google adsense.
Thanks and Regards,
