Everything we do at Merkle is based around data, and not simply opinions or best practice. We make absolutely sure we create a testing hypothesis, based on a combination of a data set gathered by various online tools.
Lebara Mobile’s main customer target is the world’s migrant community; anyone who has left their friends and family to live in another country and wishes to keep in touch with loved ones in the most efficient way possible.
We focused initially on the German market and segmented users by their browser’s language. Interestingly users with no German or English browsers were responsible for more than 25% of the total revenue. Based on this discovery, we personalised their “international rates” slider (on their rate page) depending on their visitors’ browser language.
Our hypothesis was that, by mentioning their home country in the drop down menu and/or translating the header in their native language, we would increase the Click-through Rate on their main Call to Action. To test this theory, we used the Optimizely platform to run three variations against the original and monitored visitors’ behaviour.
Shown below are the total four variations for a user with a Polish browser.
Variation 1 - Drop down menu is populated automatically based on browser's language e.g. Poland
Variation 3 - Drop down menu is populated for Poland and header is in Polish.
The variations proved successful across the board, but Variation2 outshone the rest. The Click-through Rate of the Call to Action increased by 66.4% compared to the original, and the statistical significance was higher than 90%, allowing us to validate the results and confirming a 9.7% increase in the funnel conversion rate, with an 11% increase in revenue per month.
Taking things a step further, we split the CTR by device and found that Variation2 worked better in desktops yet Variation1 worked better on mobile/tablet devices. Lebara Mobile now implement the two different tailored experiences by each device to ensure optimum results. Simple, yet very effective!
