I'm starting an indepth study in SEO and SEM (i.e. I'm a newbie). I am lead to beleive that there are two types of keyword research
1) for organic SEO. You do your keyword research FIRST to define your niche, find out what people are typing in google, so you can make your site conform for that.
The key is to figure out what people are typing in to find out about your topic. How do we do that? (say someone wants to find out how to be more confident in their city).
2) for PPC/adwords. These keywords and ad copy may or may not (in most cases even) be the same as #1.
It seems that there are tons of tools out there that help with this.
Can anyone elaborate on this?
