I am relatively new here but this is what I have learned.
Select a title relevant to your topic. Select sub-titles the same way. Try to use the title of your hub in the first paragraph of your hub.
Select sub-titles the same way and also attempt to use the title or at least part of it in the first line or paragraph in the text capsule.
Use lots of capsules. I try to put 1 - 3 paragraphs or thoughts in each capsule.
This will hopefully maximise your success getting readers. To maximise your success with amazon you need to pay attention to choosing products to showcasethat are relevant to your hub subject.
Not sure about adsense, if one can tip the odds to make money. I think that depends entirely on the amout of visitors to your site, and how many of them choose to click on the advertisements.
Have fun writing on HubPages!
