With regard to niches, my experience has been the opposite.
If your niche is small enough, you can't properly bid on adwords for rare keywords because they are flagged as "low quality" and you are forced to either abandon those keywords or pay 10x for them to show.
This, of course, defies the entire raison d'etre of adwords - the whole purpose of which is (presumably) to bid on a keyword that targets that one rare person that searched for that.
But it can't be done - if only 5 or 10 people search for a phrase or keyword every day, it cannot be bid on properly.
Alec Brownstein did exactly that by ad targeting his favorite creative directors' names some years back in order to land a job. It worked.

I was faced with keyword combinations that had "natural" costs that were very low (and appropriately so, since I was the only person "bidding" on them). But then a few days later, "low quality score" and they ratcheted up the price 10x.
If you get a job out of it, the penalty doesn't really matter ... I was trying to convert $5/mo IaaS customers.
How do you define a great vodka? With blind testing?
If its like beer, then there's a few types of beer and perhaps some spice but its mostly the same.
That is why I think CS and software engineering should be part of every college degree, so that people can see the opportunity for software where it exists. I wasn’t good enough to be a programmer but I had enough knowledge to see an opportunity whereas most people thought “hm, this is just how this is done.”
> Here's an exercise you can do: do you understand what a life insurance agent does all day every day? Make it your mission for a week to do so, well enough to explain it to a close friend who has no access to your sources. All you have to do to learn this is read and make conversations happen. (People are happy to talk to you!)
I really need to take that seriously, and talk to people in a lot of different industries.
