I am looking for a programmer to write a script that will allow me to do A-B testing of an image on my web site. For an example of the kind of A-B testing I am talking about, see this report:
[url removed, login to view]
Basically, I want to experiment with how many sales my web site makes when a particular image is displayed. (I am trying to answer whether it makes financial sense for me to continue to pay [url removed, login to view] its annual fee for my right to show the TrustE privacy logo. I have no way to measure if displaying TrustE's logo on my web site has actually increased my sales.)
The script you write should divide my web site's visitors, in real time, into 2 groups. Group A sees the image, and Group B does not see the image. Whether the image is shown can be achieved by a cookie. The purpose is to see which group is more likely to purchase from us. Therefore, on my web site's "Thank you for your purchase" page, the page they see after we have charged their credit card, we can insert code, such as the loading of an image, that logs whether the image was displayed to that customer. (You would provide us with this code.)
In addition, I will need a reporting page to tell me how many total sales have occurred for Group A and Group B and the percent difference.
The code you write will need to work with any graphic. In addition, I would like an HTML interface created that will let me create new tests and specify the A-B test subject's parameters (i.e., the URL to the image on my web server, and the destination hyperlink for that image). After supplying these parameters, the script you write will show me the code that I need to insert into my web pages in a way where I can easily copy-and-paste that code. The script will need to be able to work in standard HTML pages and PHP pages.
If a database is needed to power this script and store the data, then it will need to be written for MySQL. My web server runs RedHat Linux. The solution you create will need to be fast, as traffic on the sight can be heavy, and we do not want you to create something that will slow down our web site.
I am very price sensitive, so if you can finish the project quickly and bid the right amount, I will end this auction early. Please write "Excel" in your bid comment so I know that you actually read the requirements and speak English. Thanks very much.
