Keyword Research & PPC

For keyword research google adwords is the best one.

I think Adwords is by far the best free keyword tool. Doesnt lag like most out there, gives you fair estimates (most of the time), lets you see estimated cpcs (you can get a general idea).

You also want to do competitive analysis of keyword research using spy tools.

google adword works fine with me..

Hi Chirag,

I agree that Google's keyword tools are completely fine for doing research, and until you make some money in your market, the price is right (free).

You can also use Google Insight to see what keywords are doing, and use Google Suggest to find more keywords related to the ones you are searching--this is good for finding less competitive phrases, with reliable search volume.

You can find services to manage your PPC accounts, but I recommend learning as much as you can on the subject first. If you know how to do it, and outsource it, you'll know when or if you're getting taken for a ride.

If you are ready to roll up your sleeves, get a good PPC teaching source (I recommend Perry Marshall's Definitive Guide), and for the cost of a night out at a modest restaurant, you can have a thorough step-by-step resource for reference and PPC ad building.

Good luck with you PPC campaigns.
