Will click-through rates increase or decrease when we cut the number of products we recommend from two to one? The results of our quick experiment are clear.
Too Many Choices?
You might have heard of the paradox of choice before. It says that giving people more choice is not necessarily better. People either feel less satisfied with their choice or are so paralyzed by the number of options that they choose nothing at all.
The most famous example is a 2000 study by Sheena Iyengar and Mark Lepper in which they sampled 24 varieties of jam in a supermarket one day, then 6 the next. Guess on which day they sold more jam?
The second. Given fewer choices, consumers bought more jam.
Way more.
Ten times more.
Putting The Paradox of Choice to the Digital Test
To test the paradox of choice for ourselves, and see whether it applies in the digital world, we ran an experiment on one of our posts—our 3-day fast story.
Our test was whether more readers would click through to Amazon (and hopefully earn us some commissions) if we reduced the number of books we recommend at the end of the post from two to one.
Would there be an increase in clicks in the lone remaining book? And would it be enough to offset the loss of clicks to the book we removed?
We set up an A/B test on Google Optimize and eagerly awaited the results.
Which Do You Think Will Win?
Here are screenshots of the two variants. Which of these two do you think will generate more clicks to see the book(s) on Amazon:
Two books:

Or one book:

Have you made your guess?
Now let’s see the results.
The Results
As you can see in this chart, there was a runaway winner…

…And the winner was the one book option.
When we recommended two different books in the post, 5.9% of readers clicked through to Amazon to check either one or both of them out. But when we only recommended one book, the click-through rate increased 40% to 8.3%.

Interestingly, while click-through rates were very different, other on-page measurements for the two variants were pretty much identical. Average time on page for both was just over 1.5 minutes, bounce rate was in the 37-40% range, and exit rate around 63%.

Why this Matters to You
Readers want you to make their choices for them so, if you want to increase conversions, don’t make them choose.
Tell your readers what to do instead.

About The Paradox of Choice
For all the science behind this strange psychological phenomena, I’ll take my own advice and stick to recommending only one book: The Paradox of Choice, by Barry Schwartz.
