You can pretty much put any kind of content on Hubpages that you want, provided of course that it is not about gambling or obscene or illegal. The hubpages services also frowns on spammy looking content and over promoting your own products and services. You want to add content on hubpages that is original, interesting, informative and entertaining. If you have articles that you have written on other websites or blogs then you can share them on hubpages but you would want to modify them so they are not like your original.

You can add photos that you find interesting to your hubpages. Maybe you have personal photos that you want to share with the hubpages community. Many people these days are posting their videos to YouTube. You can link to those videos as well. Perhaps you have written an article and a video is available that shows the visitor precisely what you are writing about. That would be a good addition to your hubpage. Keep your hubpage lively and fun. That will keep the visitors coming to see your hubpage.
