Keyword Research

Can someone tell me keyword research tool that give relevant keyword results.
Example i've choise the keyword "online marketing" and i've tried several keyword research tools. All of these gave me different keyword searches per day/month for that specific keyword.

Here are the print screens

 

Try the Google Keyword tool with setting the "Match Type" to Exact. It returns 165,000 result (per month) for therm "online marketing"
Good look

 

Use wordtracker it is the best online keyword research tool on the internet.

 

If you want to optimize your site for Google with those keywords i think you should use adwords keyword tool. Google have most relevant information about searches per month in their own search engine.

 

I would second on bane06 suggestion. Google Adwords Keyword tool. It will help you get new keyword ideas and most relevant info.

 

Yups you are right, Follow that way, you can check lot of options there...

 

Google adword keyword tool is best
