You are not the first to ask me, so no problem.
I am laughing as I type, but I truly do wish I had a better answer for you. This will sound rather ditzy, but the honest truth is that I don't know. I am signed up with something called adsense, but don't even know if I've done that correctly.
I probably need to learn more about the business end of hubbing, but I just write. I do read a lot of hubs, including bits and pieces from hubbers who say they are making money so I would recommend that you check those how to make money hubs out.
They seem to focus on writing about products and that could be done in tandem with writing for the love of it, but I haven't taken the time to really work at it. I've mostly focused on refining my writing, however, I do plan to one day get around to learning about how to make it a business.
Or maybe someone who loves me will figure out all that stuff for me and let me just write. I wish! ;)
Just looked at your profile and first hub again. Your first hub speaks well for the potential you have. I do know enough to help you with a few things as you get started. Read several hubbers profiles and then make one for yourself. Use videos that pertain to the topic of each hub and add advertisements from Amazon once you are signed up with them. Link your hubs to each other, and to other hubbers with related topics (making sure their hubs have some quality work). The options at the upper right hand corner of the hub construction page will allow you to do these type of extras. You can add to or change old hubs by going back to edit them. Follow hubbers selectively is my advice because I think that is what will encourage good writers to participate on hubpages, but I think many hubbers follow any kind of writing that shows up. However, I'm probably not the most qualified hubber to get the best advice from for any aspect of hubpages.
Thanks for thinking enough of my work to ask though. Nice to meet you.
