STELLA Service awarded for “Excellent” Customer Service based its review of how it handles customer service issues. Once awarded, STELLA Service wanted to show that the Stella Service Award was worth placing on their website, and engaged Inflow’s CRO team to prove the seal could increase the website’s eCommerce conversion rate and revenue.


The CRO team conducted an A/B/N Test of the Stella Service Seal on

Placement: Inflow’s CRO team knew that’s shoppers, like all online shoppers, valued proof that their post-purchase experience would be a positive one, especially if there were issues or questions with their order.

Context: Inflow’s CRO team recognized that online shoppers may not yet recognize or understand WHAT the STELLAService Award Seal represents, so a clear context was given to the seal by adding copy treatment that would sit adjacent to the award badge. CRO Analysts arrived at 5 copy treatments for the customer service award seal they felt would let customers know what the award was for, and what it means to them.

Analyst Notes

When STELLAService asked us to optimize their badge on the site, where to start was pretty clear, as we felt that online shoppers just did not understand what the award was for, and if they knew, they would trust the site more. We know that the customer service concerns are forefront in the customer’s minds today, even more than online security, and if they had the assurance that the online store had good post-purchase customer service, they would convert much higher.

We believe that benefited so much from the STELLA Award because its online shoppers greatly valued excellent customer service and the seal provided the assurance that many needed to “pull the trigger.” While this may not be so extreme for all online stores, it is bound to have a positive impact with those that are 1st-time customers, and do not yet have established the trust required in a website to make an online purchase.

Since this seal is so common and powerful, companies should display their STELLAService seal if they have them (Find out if your store has a rating yet). If they don’t have an award yet, they should start the process of requesting it, as for them, like, it might be a game-changer.
