Hello Pankaj, sounds like you need some extra Karma. Adding Karma is easy. Next hub you write, check and see are there any other Hub Page writers writing something similar to what you have written, or perhaps a hub you wrote previously. Adding Karma just means adding a link from your hub to theirs, and somewhere along the line someone will add a link to one or more of your Hubs also.
Just go into Hub Edit mode and select a link capsule, place it somewhere you want it to be, and copy the Hub link from the target Hub page you want to link to - into the capsule. You can test the link before hitting Okay. And then clicking Publish. Another way to add Karma is to just do a link within a text capsule. Put the word you want in bold, and highlight the word, then at the capsule's top, look for the "Link" icon, looks like a "8" on its side. Click that, and when a dialog box opens, just paste the link from the Hub Page Url you copied from the target Hub into the box and okay it. Now publish the hub. And presto, you have added Karma and your Karma rating will go up the more you do this! remember - you don't have to cope the whole link onto the page and have people read the link, you can have any word as the link, just highlight it in the text and make a link out of the word or sentence. Hope that helps.
