Google Adwords is the ultimate advertising venue for online marketers and businesses. It gives you access to one of the largest pools of websites around in addition to Google’s advertising listings. Marketers love Google advertising services as it comes bundled with a bunch of complementary services. One of those useful services is Google Adwords Keyword Tool. It’s a powerful tool if you want to get your keyword research done and create a powerful seed list for your campaigns. Best of all, it’s free. So there is no reason not to take advantage of it.

Unfortunately, many marketers assume that Google Adwords Keyword Tool is the be all end all of all keyword tools. Have you ever wondered why people pay for premium keyword tools when they can just use Google Adwords Keyword Tool? There is a reason for that. The tool does provide you with some decent information, but it doesn’t give you a complete list. I have also found the stats from WordTracker or Keyword Discovery to be more useful that numbers and stats provided by Google Adwords Keyword Tool. Premium keyword tools may cost you some decent amount of money, but when used in conjunction with Google’s tools, they can help you create a better, more comprehensive keyword list.

Keyword Discovery: one of the most powerful keyword tools on the market. While many prefer using Wordtracker, Keyword Discovery has its own advantages. It comes with a variety of features to help you slice and dice your keyword lists.

WordTracker: has been around for years. It’s used by many SEO and advertising professionals. If you are into digging and digging more, WordTracker is a reliable too to consider.

Wordze: has improved a lot in the past few months. For a long time, Wordze wasn’t considered as a true contender to WordTracker and Keyword Discovery. But now it is one of the best keyword tools on the market. Comes with a ton of features and can help you build great lists fast.

Keyword Country: a must have tool for those of you who are focused on niche marketing. You can use it to find new keywords, spy on other people’s successful campaigns, and even improve your landing page’s conversions.
