You have to sign up with a valid Google or Gmail account, and you will initially be taken through the steps to purchase pay per click advertisement with Adsense as soon as you arrive on the Adwords page sponsored by Google's Adsense. Instead of starting your first advertising campaign, navigate your way to the Google Adwords homepage once you are registered. Select the reporting tools tab and click on the Adwords Keywords tool from the drop-down menu. Once you have found the Keyword tool, you are now ready to start searching for the highest paying and easiest keywords to rank for. You can type any single phrase into the keyword tool and receive results of that exact word and any cousin keywords the system picks up. Multiple terms can also be searched by separating each phrase with a comma. Competition: The competition bar indicates the level of internet marketers that also focus on this same keyword. Keep in mind that this reading is geared towards people intending to purchase pay per click advertisement that will appear on pages and search results that focus on those specific keywords, so this is not an exact reference to the amount of writers or webmasters that are also trying to rank for this keyword. Local: This is the amount of times that a given keyword or phrase is searched locally, this pertains to the entire United States. Global: The amount of times a given keyword or phrase is searched throughout the world. CPC (Cost per Click): The CPC rating of a keyword or phrase represents the average amount that an advertiser will have to pay for every time someone clicks on their ad through that keyword. Google only keeps a very small amount of the cost of these clicks, if any at all, so you can use this amount to determine about how much you will earn every time someone clicks an advertisement on your website for that specific keyword.
