When you decide to step it up a notch and use Google tools keyword search, you can efficiently test almost any niche market or product to see if it's worth bidding on. Who wants to put a bunch of time and effort into something that doesn't give your efforts back? 

The Google tool keyword search is very powerful and it's free! In my opinion, not leveraging the power of the internet doing the minimal amount of work needed is crazy! Traditional marketing strategies are out the window, in order to succeed in today's marketplace you absolutely need the adwords keytool...

The adwords key is to use words that people are looking to buy, and not just keywords that people seeking information about a particular product. In as little as a day a person can decide if their current niche market is still worth investing in. The ad words key tool will break your campaign down, showing you conversion rates, click through rates (CTR), google analytics keywords, and much more. It's pretty much a science!

Rather than just blasting out an ad with a bunch of niche keywords you feel will work well, you should advertise with just a select few keywords. Some people even use just one keyword per ad. It's also wise to use exact match keywords when starting out.

After applying these few tips, and your campaign is looking strong, slowly expand your number of keywords or keyword phrases and then think about going for a broader match, using the content network.

Keywords that include product names are very effective, even product related keywords or phrases. Remember to avoid really broad keywords though, long tail keywords is what you are looking for. Usually when people are ready to buy a product, they know what they want and they type in exactly what they are looking for. That's pretty much the definition of a long tail keyword.
