The first thing you want to do is look at your list and think about where in the buying process you would be entering the niche. Using "WordPress Tips" as the example that stands out... Tips are great.. tips are used by people that are using WordPress and looking for advice to make their site better, and work better... are you seeing where in the buying cycle this is? This is in the back end or "Support" portion of the buyers cycle.
Web Hosting.. I really would not call this a niche.. this is an add on type o thing to a niche you are in. IF you were to select WordPress tips.. then a natural side affiliate program would be hosting.
Then you get into looking at potential income.. I would write writing off.. we all know what to be authors are broke! LOL
Android apps.. start looking at some of the affiliate programs out there for this one..you had better have a ton of traffic.
I am not going to say dating is saturated.. because saturated is usually a good thing.. I will say that it would be difficult to create a unique perspective to stand out from the competition.
So out of the list you are kind of left with IT. Web Hosting is IT.. so that could be one source of revenue. So the question then becomes..... <drum roll> How deep can you target with IT.. what micro niche can you pull out of your... left cerebral cortex has an amount of interest on your part... and the product or need to supply answers? I will throw out some examples I have run with in the past. Drones ( still a hot topic, plenty of product.. with all the new state laws plenty of content possibilities) would be easy to pull authority here.
3-D printers.. hot hot. The units are not that cheap, and either is the mid to top end software to run the things. If you really have an interest in this, think CONTENT. when I say content I mean already done for you plots so a person can download and print. I honestly can say i dont think I have seen much of this in the market space.
But those would be examples... I consider them micro'd down quite a bit, but there is huge audience availability in those - among others.
And saving the best for last... If you are stepping into Internet Marketing for the first time... PLEASE dont get into making money online.... How can you tell others how.. if you havent?
