I checked out your profile and found out that you haven't written a hub yet. To increase your hubkarma, first start writing a hub. When you are finished writing the hub, publish it and then click on the link, suggest link. It would then suggest some links to you. This way you can add some links on your hub and your hubkarma will rise. But while selecting the hubs for linking, make sure its a good one. Cause you don't want to deliver bad content to your reads.
And the best way to driving traffic: Write your own and genuine articles. You can of course do a little research over an article, but it is not encouraged you use the same content as this would lead to your account being blocked. However you can make citations from that webpage, but make sure you llink them back and give them the credit.
