Once you start your ads for your Google Adwords campaign, you must be informed what keywords or keyphrases will be compelling to your target so they can identify your ad easily. Perry Marshall, Google Adwords guru, promotes making full use of the Google Adwords Keyword Selector Tool when doing each ad as it can be of big help to pay-per-click managers and all Adwords users. Among the benefits that this free tool can give you are as follows: finding the most popular and profitable keywords in your niche, and drilling related keywords useful in your other campaigns. You can fine tune your efforts with Google Adwords Keyword Selector Tool if your ads do not perform well; it may mean that they are not getting enough click-throughs due to low-traffic keywords.

Here are some more ways to use the Google Adwords Keyword Selector Tool effectively for your Adwords campaign:

1. Start with a broad search. Using very specific keywords or keyphrases with regards to Google Adwords may not be a good idea because you only get mediocre results. Do a broad search instead and drill down your results using the 'synonyms' tool that offers suggestions and variations as part of the results.

2. Use a set of similar keywords as you create different ad groups. Make sure you are creating an entirely new ad group for every campaign so you can keep track of what is working - and what isn't. You can also make use of the 'relevant keywords' feature already built into the Google Adwords Keyword Selector Tool that helps you narrow down your search with ease.

3. Employ a 'negative keywords' strategy. Google Adwords campaign's optimization may require evaluating words and phrases that do not in favor of your market; you may adjust the Google Adwords tool so that it will only display relevant words. For example, if you are selling greeting cards but your basic search keeps showing results for 'free greeting cards,' you can eliminate the word 'free' by designating it as a negative keyword. Google Adwords Keyword Selector Tool now shows results but the word 'free' will not be seen.'

4. Use the Site Content feature if you don't know where to start. Google can scan your web page and offer suggestions of keywords based on your site's content. For example, if your home page provides information about services and trends in your marketplace, these may be strong keywords for your particular niche. When the scanning process is complete, you will see a list of highly targeted keywords related to these ideas and topics in your results.

5. location, location, location. Many people fail to realize how important adding a location - whether it's a town, city or state - to your key term or keyphrase really is. This is especially important if you offer products or services within a particular zone or area; the traffic you can generate from these keywords may be much higher than a general search, and will get you highly targeted, even qualified traffic. Consider appending a keyword or keyphrase with a location to determine the best combinations for your ad campaign.
