A few questions about niche research

Hey warriors,

I haven't made too many posts in this forum up to this point because up until now internet marketing has been something I would LIKE to do, but with a good job that has kept me busy, I haven't NEEDED to do it.

Well, stuff changes and it looks like it might be time to adapt. Without going into much detail, I have a little more urgency now.

I know there are a lot of routes you could go in this industry, but I feel like product creation is a great place for me to start.

I'm not a complete novice to the concepts involved in making money online, but I'm quickly learning that understanding the concepts is different from knowing the application.

So, without further adieu, I have a few questions about niche research.

I've heard that most people fail to go deep enough into a niche. They might stop at just bird watching and create a product for that, when they maybe should have created a product for people who want to watch birds in the northeast and have cataracts..... Ok, maybe not that far. But you get the point.

First of all, what questions do you ask yourself about the subject or the people you are marketing to so you can go deep into a niche? Questions like, could a persons age, health or location help me create a more specific product?

Second, what are your general rules about keyword research? How many searches for your keywords are you looking for?

Hopefully these questions are understood. I find it kind of hard to word that first one.

Any input or advise would be greatly appreciated.

Thanks,
Matt
