Just keep in mind I am not claiming to be an expert or anything....These are just things that I have found that seem to work for me.
Really the most important step is your niche research, screw that up and you will not make any money no matter how well you do the rest.
I could not think of an example earlier that I was not using. But lets use lawn furniture for now. Compare that to digital cameras where a lot of people are going to be searching for specific brands and even models. Nobody (or very few at least) is going to be typing in a specific model of outdoor chair or table. There are probably a limited amount of keywords in that niche that get enough searches that are worth going after even if you group them together on one site. Setting up an autoblog is not really going to work very well if you are going to have maybe 10-15 pages total.
Buying or action keywords are almost always the best no matter how you are monetizing your site. Whether you are using adsense, Amazon, clickbank or whatever you are going to want your visitors to take some kind of action so you can make some money from their visit.
I actually have a couple of health related sites and they started off as autoblogs with wp-robot but I had a very hard time with them going off the rails with the content so I ended up getting some original content to add to the sites. I kept most of the generated content that fit but baby sitting the sites was more than I had time for. There is a very good possibility that there was a way to fix the posting issues but I did not find it and for me spending the time tweaking the settings endlessly to find the right ones was not something I really had time for.
As far as monetizing sites go I have had fairly good luck combining adsense and Amazon on the same sites. More than clickbank but honestly I think it is just a matter of the niches that I have chosen so far. I have a couple in mind that I think will be a good fit for some clickbank products I have looked at but have not had time to get them going yet. One thing about clickbank is that there are a limited number of decent products which makes those niches somewhat more competitive and it is hard to find something where I can target multiple keywords on the same site. Really just not very conducive to building my little pyramids.
