How a Customer Testimonial Cut Our Sales in Half

January 8th, 2007 by Mike Read more about Conversion Rate, Copywriting, Landing Page Optimization

You would think that a glowing customer testimonials would help to boost the conversion rate of your site? Think again!

We just added a powerful customer testimonial to one of our landing pages and as a result we saw the sign-up rate of our page nosedive.

Here is the landing page with the testimonial:

The customer testimonial reads:

The MindValley Way should be required reading for everyone that is thinking about growing or building their small ecommerce business.” James Fox

Surprisingly, the identical landing page without this testimonial converted way better!

Here is the landing page without the testimonial:

The detailed test results for this test are:

What did we learn from this?

  • Not all customer testimonials are created equal
  • Test customer testimonials and do not assume that they will help your site convert better

Why do you think that the landing page with the testimonial did so much worse?

Here is two potential explanations that I came up with.

  1. The keyword group for this landing page was for “Alex Mandossian” and the testimonial is not perfectly targeted
  2. The testimonial is too high up in the copy and you first have to engage the reader and suck them into the copy

Either way, we were definitely surprised by this finding. My guess was that the testimonial should have helped, not hurt the conversion rate of this landing page. I would love to hear your thoughts on this.

    The only words I saw, when I looked at the testimonial the first time were ‘required reading’. That promptly gave me a bad reaction.

    I read it a second time after reading the rest of the page and then I thought ‘marketing hype’ ‘not a chance am I getting scammed with this.’

    didn’t sound like a real person talking, sounded like someone you paid to say things to make me want the product.

    I’d guess it also has something to do with the traffic.

    That’s not really enough, for me, to call it a reliable test and did the clicks for both tests come from the same source, same etc, etc ?

    Not where I’d place the testimonial either, it should enhance or give social proof to the copy around it and, to me, it’s out of place and off topic.

    Maybe if it were for the actual product, which in this case, is the ecourse, not the ‘Way”.

    Just my 2 cents.

    We can call the above test reliable because all of the traffic to the two landing pages come from the same source and the results are statistically valid.

    We run a landing page optimization software from http://www.clickmuse.com to create all of our landing pages and split tests.

    In regards of the placement of the testimonial I agree with you that there are probably lots of better places to put it and we are now testing those to see what will happen.

    My immediate thought was the statement “required reading.” That phrase might do fine, but required reading at the top of the page, before I even know what I’m supposed to read, completely turned me off. I have enough required reading; I’m looking for something I will want to read that will help me achieve my goals. Required reading might even work if there were a reason why. “should be required reading because it will help you…” might work better.

    I also have the same impression when I first read the testimonial box..I felt like it was some sort of a scam..that they just had the person paid to say positive feedbacks for their company…I guess this study shows that Netizens are already smart enough and are not easily influenced by other people’s view.

    [...] A Testimonial Can Lower Subscribe Rates It may be hard to believe that adding a glowing testimonial could lower your subscribe rate on your opt-in list. That’s just what happened to Mind Valley Labs when they added a positive customer testimonial to a squeeze page they where testing. The results without the testimonial were twice as good as with it included. This could be a result of improperly positioning the testimonial on the squeeze page, or not having a properly targeted testimonial.

    I may be way off here, but the “small” is what stood out to me. I wonder if it turned off people who in their minds were not “small”?

  12. KDye Vertical Leap

    Hmm, I saw “small ecommerce business” and wondered if that was it (if the visitor didn’t fit that definition it put them off).

    Interesting post though.
