I’m looking at doing some PPC and search engine optimisation, but I have been getting stuck with the keyword research (it’s a lot of work!).

Which is the best tool to use? I don’t mind paying for one, but it must be worthwhile!

Thanks!

For those categories :
* bluetooth dongles
* camera batteries
* memory cards
* ink cartridges
* ink toners
* crumpler laptop cases
* external hard drives
* ipod accessories

When you are looking for products online do you search by basics keywords or specifics keywords ?

thanks
for exemple, you want to buy some ink cartridge, do you type the keywords "epson ink cartridge" or the keywords for the specific product you are looking for your printer : "Epson D120 ink cartridge"

thanks
