Write about topics that you know a lot about, and really care about. Break the text up into multiple capsules, add pictures, videos, and join amazon.com to put some appropriate amazon ads on the hub. Use as many capsules as you can. If you can find a relevant video for your hub, then add a video too.
Backlink your hub. . . .all that means is sharing the link on other websites, the more the better.
Be patient. Hubs take at least six months to really become favorable to search engines.
