Why Split Testing Is Crucial To Your Sales Letter's Success

4 replies
First, for those who don't know what split testing is...
A/B testing, or split testing, is a method of advertising testing by which a baseline control sample is compared to a variety of single-variable test samples in order to improve response rates. A classic direct mail tactic, this method has been recently adopted within the interactive space to test tactics such as banner ads, emails and landing pages. - A/B testing - Wikipedia, the free encyclopedia
Split testing is the most vital piece of the puzzle with your online sales campaigns. Why? Because if you're not doing it, you could be missing out on piles of cash!

Why split test?

A small example is a WSO that I ran here on the forums.

The headline of my WSO was dynamic. I had an image that was rotated in and out using a small PHP script that I put together. 50% of the time one would show, and 50% of the time another would show.

If I hadn't done this I would have missed out on $1,327 worth of revenue.

After a few days of testing I found that one of the headlines helped the sales letter convert at a whopping 14% instead of a measly 3% for the other. Obviously testing was imperative to the money I made from the WSO.

How to split test

Split testing is super easy. Especially if you've got what you're testing on your own server.

Google offers a 'Website Optimizer' that will allow you to test two different pages. The differences between the pages can be anything... but I'd recommend only testing one element at a time so that you know exactly what converts well.

You can access the Website Optimizer by going here: http://services.google.com/websiteoptimizer

Once inside, Google gives you great directions on how you can set it up on your site. It's a simple Javascript script that will run on virtually anybody's computer that loads your site up, so compatibility is a non-issue.

Start with only two versions of what you're testing. Once you get the hang of it, you can test more but two is a good starting point.

So let's get discussion on this topic rolling. If you've done any split testing before, let's hear some of your results. What sort of conversions were you seeing before and after you tested?

      Split testing is why most IMers don't succeed.

      It's not just Sales letters:
      • Websites
      • Adwords Ad copy
      • Emails
      • Thank you pages
      • Offer
      • Pricing
      I could go on and on...........you must constantly TEST to be successful.

      I personally know a very successful IMer who makes over 5M per year. He said he was successful because he Tested EVERYTHING he does, over and over...it's really that simple.

      Problem is, nobody wants to spend the time testing, it's Boring.

        Ha! You're totally right. It is boring... but once you start seeing what small chances are able to do, it gets less and less boring!

          Nice thread. I discovered split-testing in the offline world, just by doing a simple A/B split mailing. The first time I did it, I mailed half of a postcard mailer with a new headline and the other half unchanged (my control piece).

          The control pulled a 1% which was profitable. The new headline version pulled a 5% or 4000% improvement. That made me a fan of testing for life.

          When I ventured online, I tried finding a reliable testing tool and after trying about a dozen of them, hired a programmer to build my own testing tool out of frustration. That tool eventually evolved into my multi-variate script Easy Multi Tracking.

          One of my more recent tests discovered a testing variation that pulled about 297% better than the control. I share that one on my blog which is listed in my sig file. I have other test results I could share but I do not want to monpolize or take over this thread.

          In closing, if you are not testing then you are leaving a serious pile of money on the table. It doesn't matter what testing tool you use... who writes your copy... you have to test, especially the major stuff like your opening headline.

          Ask your copywriter for an extra headline or two to test with. The results might put a smile on both of your faces.

          Take care,

          Mike

  • We've seen similar test results for ourselves, and clients. In fact, one advertiser's newly tested headline resulted in rejuvenating the ad as a main control for 4 additional years!
    When we launch a test, we can barely sit still waiting for the results to come in!

    Brainstorm different test ideas... always! Write them down, prioritize them, schedule them... tests lengthen the life of offers and media!
