Dr. Kowalich modified some of the Taguchi arrays in order to give more factors for testing without regard to factor interactions. To this end, he used the L12(211) and L18(21 X 37) due to these arrays having the interactions distributed evenly across the array columns. Here is a list of the Kowalich arrays. Read more
A rarely discussed and utilized property of the Taguchi Method is the study of interactions. Dr. Taguchi incorporated additional power in the use of orthogonal arrays for test design via the linear graph. Using these linear graphs it is possible to assign factors to the correct columns in order to study interactions between the factors while also revealing the effects of the individual factors.
Although it is not possible to study all interactions as can be done with the full factorial test, you can use your knowledge of Read more
OK, that title got your attention! What I am talking about? Well, some people promoting Taguchi methods of testing suggest that you can eliminate under performing test runs during the test. Here is a quote from the guy that runs StomperNet’s test software:
Lets say you are running a L18 — this has 18 different landing page recipies. While the test is running you will naturally see a couple of recipies that are doing significantly worse than the others. As this happens you can shut off these recipies. You can keep doing this until you are down to two recipies — i.e. - a split test which will confirm the results from the teguchi test.
“Why use Taguchi methods?” - that is the first question most people ask when told about our software. The short answer is it allows you to quickly optimize your website conversion. That may be all you need to know, but I’m going to give a much more detailed answer.
The Taguchi method was developed by Dr. Genichi Taguchi. After World War II he was employed by the Japanese Ministry of Public Health and Welfare to work on the first national study of health and nutrition. This work led him to Morinaga Pharmaceutcal where he explored efficient Read more
This is a tool you can use to check the similarity of two articles. The tool allows you to use either a DupeCop type comparison or a higher order shingle function comparison. Click below to go to the tool.
If you want the DupeCop functionality, then check the DupeCop checkbox. The more robust checker allows you to weigh the top part of article more relative to rest of the article. This was done because some speculate that search engines may only check the first Read more
Here is an awesome web 2.o graphics pack to give you a quick start in developing test factors. This is your’s to use as a user of our Taguchi Split Test software.
Here is a look at all of these graphics, giving you a break down of everything you get, along with full size samples… Read more
The solution you choose will depend on the volume of traffic you have. Taguchi type methods are based on what is called a fractional factorial test and use statistical techniques to reduce the volume of traffic to get a significant test. The Google Website Optimizer is based on a full factorial test and will require much more traffic to get a significant result.
Let’s say you have 15 factors with 2 variation per factor. Using Taguchi based methods you have 18 page variations in the test. Using GWO (full factorial) you have 32,768 pages to test. To get a valid test Read more

One feature not mentioned in the video is that the code can be placed on a shopping cart page not on your domain and it will get tracked. This allows you to use the software on any site with an off site shopping cart. You do have to be able to place your code on the cart pages.
The setup loads files for your site in your site’s directory on our server operating in the Amazon EC2 Cloud. Using the Amazon EC2 Cloud allows for a highly reliable server and fast loading of the files by browsers. The number of sites on each of our Amazon EC2 servers is limited in order to maintain performance and allow for at least two years of data storage.
Another advantage of using Amazon EC2 is quick update of the system software as we add new features. It allows us to do the updates without any adverse impact on your site’s tracking and testing.
Use this front dashboard page to monitor your site’s activity and get an overview of traffic levels and sources. The other dashboard pages will give you more details regarding referrers and visitor interaction with your site. The data presented by these dashboard reports can give you ideas on where you need to test to improve conversion.
You can click the calendars in the right column of the dashboard to pick the time period to review. The time period you pick will then be used in all the other dashboard report pages. You can segment reports based on visitors per hour, per day, per week, or per day of the week.
This report page has a wealth of information. It helps you discover where you are losing visitors and where you are capturing their attention. That information can be used to improve the design of your overall linking structure. I can tell you with confidence, you will spend hours studying this report and the ideas will flow.
Don’t forget the link at the top of each box that takes you to the referring page. This makes it easier to discover your ranking in the search engines.
The keyword page can tell you all those keywords you never knew visitors were using to get to your site. It is a good idea to create specific pages for all those words. Link to that new page from that keyword’s entry page and you may get a double listing.
I am always surprised by how visitors interact with my pages. It seems to rarely be the way I pictured it. This dashboard report helped me discover that fact and learn the parts of the page that caught the visitor’s eye.
Using this information allows you to get your most important message in the visitor’s focus area. That will improve conversion.
In the right column, there are graphs showing percent visitors who scrolled on the page, percent of page viewed, time spent on page, bounce rate and percent visitors who clicked a link. One graph that was not shown on the video was time flash file played. If you have flash on the page in the report, the graphic for flash view time will be shown.
OK, this world map of visitors is just fun!
However, it is important to understand where your visitors are located. It may be that you need to create a translation of your site into another language in order to maximize conversion. You can discover this by reviewing the world map of visitors.
The software gives you the ability to split your traffic between the control and test pages at whatever level you specify. This option is used to maintain income from the control page while trying to find a better performing page.
If you are driving traffic to your site using PPC, you can specify in the URL a query variable that tells the software the ad variation that generated the visit. This allows you to test ad against landing page so that ROI on PPC is maximized.
The text input at the bottom of the links list probably needs more explanation. The final target action, such as cart checkout, may be several levels away and a direct link to it is not on the test page. In that case, you can put the target URL in the text input area. As you use the text input, a new one will be created so that multiple inputs can be entered.
Note on the list of links, there may also be form submit entries and flash play entries so that those can be tracked. All of the actions you specify here will be reported on during test and can also be edited during test.
