The Challenge: Data Without Context is Misleading

The Dutch retailer has a wide array of lamps to choose from.

The product pages are rich with images, reviews, descriptions, and technical specifications.

In a bid to increase Add to Cart and revenue per visitor, Mintminds delved into qualitative (HotJar) and quantitative (Google Analytics) data for these product pages, and formulated a preliminary hypothesis.

It was clear that visitors paid a lot of attention to the product specs blocks, in particular the Show More link, and they also used a telling combination of category page filters – mainly Fitting, Material, Style, and Shape.

Keeping this in mind several A/B tests were conducted:

  1. One variant highlighted specifications based on the filters used on the category page
  2. Another auto-expanded the product specifications, without the need to click “Show More”
  3. A third swapped the specs with the product description
  4. A fourth placed a link to the specifications above the image carousel

Plot-Twist – Surprisingly all 4 tests showed significantly lower add to cart and revenue per visitor. None beat the control.

Mintminds returned to the drawing board and sought context for the data through User Research.

The insights mined were:

  1. People want to view more pictures before adding a product to the cart. They are keen to inspect the item from different angles.
  2. USPs like “In Stock” and “Fast Delivery” also pique interest and generate purchase traction.
  3. Highly technical specifications mean little to (most) buyers.
  4. Buyers prefer filters that let them sort products by attributes that can’t be deciphered from the product images. Like whether the item comes with a bulb, or not.This in particular told a different story from the quantitative Google Analytics data which indicated that the most used filters on category pages were related to the structure and the build of the products.

Based on these findings a new hypothesis was crafted:

If one important product feature or USP is textually shown below each product image from the second product image onwards (in the carousel) then the number of transactions will increase since buyer information needs will be better served in a location that is already frequently viewed.

The Test: Placing Specifications/USPs Under Product Images

Mintminds used Convert Experiences for the test.

A script was run where specifications or attributes that mattered to prospective buyers (as sourced from User Research and Google Analytics) were formulated into statements and placed on the carousel images from the second image onwards.

The test was shown to all segments – new and returning visitors.

For both desktop and mobile.

To prevent the chance of a false positive, only 1 variant was coded.

A custom segment was used in Google Analytics to fire an event when the 2nd carousel image entered the browser’s viewport. This was the cue for Convert Experiences to serve the variant.

The Control:

The original product page, without any tweaks.

It was served to visitors over 28 days.

Revenue per Visitor6.58%

ROI of Test: 116%

Drilling into segments, return visitors and those who shopped on smartphones saw a 19% increase and a 15% rise in the Add-to-Cart metric at statistically significant levels with the variant.

This is intriguing since these segments also registered the largest number of sales, after viewing product specifications, pre test.

Product carousels without further context (attribute and spec data) are very similar to a comic strip with empty speech bubbles. Readers fill them in with their own stories, which may not serve your goal of driving more sales.

Convert is happy and proud to say that this test was nominated in the category of “The Best A/B Test” for the DDMA CRO awards 2020, and went on to win the Dutch Search Award 2020 for best CRO campaign.
