Keyword Research/Analysis

I've been using a tool to do some keyword research, but I'm not really sure I know what I'm looking at.

I know I should look for sites that have a low R/S (results to search) ratio. However, does that apply if there are 4.5 million results?

Here are the stats for a keyword I'm thinking about going after. It is a one word keyword and it's fairly popular (I'm not going to say "competitive", because part of my question is what that really means).

Searches: 134K
Results: 4.5 Million
R/S: 34
Google Ads: 81
Yahoo Ads: 53

To me, this looks ripe for the picking because R/S under 50 for a word that is searched for that much is hard to find. I have a feeling I should be looking at much more before I put the time in to add a page to my site!

What do you base your keyword research on? What sort of tools do you use?

 

Here's what I do when deciding whether to go after a certain phrase. This might not be the best time to do this though with Jagger going on, but I take the top 5 results and paste their URL's into uptimebot.com to find out how many backlinks, etc. they have and if I think I can get more than what they have then I go for it.

 

Thanks, I'm going to go do that right now!

 

Thanks for the tip. I'm pretty sure the tool I'm using is just searching for the keyword.

What exactly does allintitle:"keyword" give you? How can I use that?

Sorry for the ignorant questions.

The allintitle search gave 325K results....

 

Allintitle shows the sites that have the keyphrase in their <title> tag.
