A new ad and website conversion testing method is available which will revolutionize your online marketing success rate. Before now, the best marketers have used split testing religiously. That preference is changing as you read this.

In case you are not aware, split testing is what allows Google AdWords masters to lower their bid price by constantly improving the click through rate of their ads. You start with 2 competing ads. Once you have a statistically relevant sample size (after 30 clicks or so), a winner should emerge. Split testing dictates that you should then delete the loser and create another ad to compete with the winner. After repeating this process 20 or so times, you'll wind up with the best performing of 20 ads.

Split testing takes patience. The key is to change one element at a time when performing new tests. If you change more than one element of an ad or sales letter, and a winner emerges, you won't know which element caused the success. Hence, if you want to be scientific about it, you must have extreme patience as you perform split test after split test changing one element at a time.

That was the old-school method. Now comes the Taguchi Method. This is a scientific method which has been used in the manufacturing industry for decades. You are able to shortcut the process of split testing while still testing multiple variables and pick a winner.

With only a handful of tests, you can test literally thousands of combinations of a dozen or more variables. Each element is statistically isolated (using a complex algebraic algorithm) so that you are able to come up with the "ideal" variation combination which produces maximum conversions.

Using this method, it is common to increase your conversion rates many times over! If you are an online marketer, you need to take a closer look at the Taguchi Method. It is clear that those employing this method will see their conversion rates skyrocket.

Given that this method is so mathematically complex, it is no wonder more marketers haven't yet adopted it. In recent years, however, some commercial products have made their way into the mainstream. Some large companies sell their Taguchi Method consulting services for tens of thousands of dollars. Other companies sell software which walks you through the process step-by-step of setting up a Taguchi Test and then tracks all the results. With the ease of conducting a Taguchi Test, this method is bound to become more mainstream.
