Q. How to Get Top Ranking Keywords on Google ?

You can also use a paid tool, such as market samurai (for advanced)

This is quite the question. If you believe you have been hit by penguin or panda updates, I need a bit more information. There are a lot of reasons you may have lost rankings.

Please post your url (do not include the http: // or the www just the domain name)

In the meantime here are some things to be aware of and consider.

Where is your website hosted? Google hurt tons of non-US based companies with the penguin update. They started doing target location matching to give people results close

eMarketing is correct its a good indicator... but let me quickly add that if you have been affected by Google and its updates and you are concerned for recovery join the google webmasters blog... if you want a link to a video for the Disavow tool and when to use it then send me a message

More specifically, go to Google's AdWords Keyword Tool.

One way to start is by going to Google's AdWords site.
