If you want to run an effective Google Adwords campaign, you'll find it necessary to learn to use the Google Adwords keyword tool. This handy little tool allows you to select keywords and establish how much you are willing to pay per click for ads that appear on web pages and search engine results pages that contain the identified keywords.

Choosing the right keywords is very important to your success in operating an Adwords campaign. You want to reach an audience that is likely to want and need your product or service so that, once they arrive at your website, they will convert to a sale or lead. Having people click on your ad does nothing but cost you money unless you maintain a high conversion rate.

When choosing the keyword or keywords that you want to target, keep in mind the keywords that your website is based upon. Those are, at least in part, the keywords you will want to select for advertising. However, you may have keywords on your website that are much broader than those that you want to use for your Adwords campaign. Whereas a person selling classic car parts online might use "auto parts" as a keyword on their website, it would certainly be a very bad choice for an Adword keyword. Driving traffic that are seeking auto parts for late model cars will simply leave the website as soon as they see what is offered and, since you choose the keyword, the click would still cost you money. Instead, focus on keywords that are very directly related to what you offer such as, in the case here, "classic car parts", for example. That way, only those people searching for and visiting websites related to classic cars and parts for those cars will see your Adwords campaign.

The Google Adwords keyword tool allows you to add and remove keywords at any time you choose. You aren't tied to using keywords that aren't working for you for any specific length of time. If you find a keyword you have selected is working very poorly, go to the keyword tool and remove that keyword from your campaign. You might replace it with a better keyword, or simply drop the keyword and not replace it at all.

The greatest thing about Google Adwords is the flexibility. You can change anything about your campaign at any time you want. Keywords that prove effective can be changed to a higher price per click while those that offer little traffic can be changed or removed. Find keywords that drive traffic that converts and stick with those keywords.

A great alternative , even better than the google adwords tool is the new keyword elite which has more options and will give you the exact adwords pricing for each keyword and per search engine as well as competition, adsense high paying keywords and so on.
