Big Jules Mag, remember one thing, whenever you publish a hub, the author score declines as the hub goes into an assessment mode. It is only after sometimes that your score will start to rise.
In addition to his, keep a check on your topic selection. Are they being searched by users in search engines? Have you done proper research before plunging into writing? Are you making claims in your writing which does not stand a chance when the light of reality is thrown upon them?
Jules, it is vital that you first do some research and come up with great information. I went through your college unemployment hub, it was good but you could have made it more appealing by introducing apt capsules, photos and better organisation. These items are compulsory if you want to stay adrift in this humongous sea (especially, if you want to make some bucks!)
Hope these ideas will help you increasing your author score. And, one important thing, read the hubs of other people and look the way they have dished out the information. This will help you a lot. Have a nice day!
