Hey guys, Garrett here (I didn't say "gang"),
I originally posted this to my team in our facebook, but thought that it might be of benefit to everyone, especially if you are struggling finding some good niches.
PLEASE keep in mind that this technique (simple though it is) is only in ADDITION to what Ed is teaching. If you are confused or just starting, just do what Ed and Dan tell you to do. With that said...
I have actually gone from choosing niches and subsequently choosing keywords to the reverse (kind of).
I've found a lot of GREAT keywords this way, so don't lose hope guys. Here's my method:
1.
Go to freekeywords.wordtracker.com
2.
Type in broad niches that I am either interested in or that I "noticed" recently. (I was at a megastore the other day, Costco, and I began to take notice of the things they were carrying the most of. I jotted it down on my phone and sent it to my email. I found 2 VERY good niches that way!)
3.
When you see a phrase that looks interesting ("leather purse" instead of just "purse", for instance)
then click the link. This causes wordtracker to run a search on that. Effectively this allows you to "dig" from a broad niche, to a narrow one.
4.
When you feel you are in "niche zone", copy and paste the best words into the "Garrett Toolbar" (or whatever tool you are using) and check the results for competition, sponsored ads, Web 2.0 competition (on Google), and the traffic on Gtrends.
5.
If it qualifies, I list it in an Excel spread sheet (google docs actually, for me) with the: phrase, wordtracker, Gtrends, competition.
6.
Repeat 
(all results in the same spreadsheet)
Using this system, I've found a couple dozen great phrases spread over 6-7 niche markets and they are completely sortable (thanks to the spreadsheet) which makes it easy to compare. But, yes, I have narrowed it down to my two BEST for the challenge.

(this is a pic of the excel sheet... keywords blacked out! Sorry)
Anyways, hope that helps!
Sorry it's not a Jing today!
