OK, close the e-books and turn off the videos.
We're going to research a profitable niche step-by-step...
What we're going to do first is brainstorm something that wakes people up in the middle of the night and causes them such agony that they can't sleep. We'll picture an individual seeking desperately for an instant solution to a problem that they need relief from RIGHT NOW!
We'll call him Joe. Now, Joe just woke up in intense pain--his feet are cramping up so he gets up and tries to straighten out his toes. He's suffering badly and nothing seems to be working. This has been going on for some time now; night after night he's losing sleep.
He's got a major problem and needs an immediate solution. So, he gets on the internet to find information on how to get relief from his foot cramps.
What does he find? A bunch of medical articles that have the information he needs, but he doesn't have a clue what they're talking about! So, he goes to another site: it turns out to be some junk site filled with a bunch of gibberish that, unbeknownst to him, was an auto-generated blog made up of articles created by a spinner (the owner of which just can't understand why all of those backlinks he/she paid for aren't generating any income!) The wonder!!

All Joe knows is that it's worthless and unhelpful cr*p so he keeps looking until he can't stand it any more. He winds up calling his doctor's answering service. An hour later he gets a call back from his doctor who tells him to eat some bananas, drink some water, soak his feet in warm water, and massage the cramping muscles. If that doesn't help after another hour or so, then he can try finding an all-night store and go buy some Potassium pills.
Well, he doesn't have any bananas and the water hasn't helped much. So, he has to get his wife out of bed because he can't drive with his foot in such pain. When they get to the local 24-hour Walgreen's they have no clue where the Potassium is so they ask the clerk who shrugs and says, "I think it's in the back with the vitamins". After searching the shelves they finally find some Potassium, but which one? There's Potassium Gluconate and Potassium Chloride, the doctor didn't say anything about different kinds of pills!!
Luckily there's a pharmacist on duty so they ask her and she clears up the whole mess and gives him some advice on how much to take. Problem solved! Joe takes a couple of tablets and in a short while his feet have stopped cramping. Ahhh, that bottle of Potassium was only about $5 but he'd have gladly paid $100 for it!
Now, Joe's wondering, "how can I keep this from happening again?" He's once-bit, twice-shy now and will gladly pay for some REAL advice on how to treat and prevent these foot cramps without having to jump through hoops to get it!
And WE'RE going to give him just what he needs!

Let's head over to Google and bring up the keyword tool.
Type in some broad phrases like:
foot cramps wake me up at night
how to prevent foot cramps at night
how to avoid foot cramps
etc.
...and we get these results

Look at those search numbers! ...and the really low competition!
Poor Joe! Nobody cares about him or helping him get a good night's sleep

Well, WE care about Joe and helping him solve his problem so we're going to research and write some excellent information to help him out. AND, we're going to provide him with a nice little e-book he can purchase. One with a diet & exercise plan along with some delicious Potassium-rich recipes. Then he'll be able to sleep through the night.
We might even show him where he can buy a 90-day supply of Potassium Gluconate at a lower price than the local pharmacy, and have it conveniently delivered to his door. No more groggy, grumpy wife having to drive him to the store at 3:00 a.m.! Surely he'll be eager to have a supply on hand, don't you think?
And now that we have a great site that delivers what Joe and 1,000,000 other people like him are looking for, we'll be getting some traffic. No doubt that now since Joe and all of these other people have found us, they'll put our link in their e-mails, on Facebook, bookmarking sites; they'll Tweet our praises to the whole world, we'll get even more traffic and make quite a few sales!
THAT's how it's done
