People ❤️️ emojis. They are a quick and easy way to express a mood, feeling or reaction via chat apps, social media and email. Now Hollywood is even making an Emoji Movie where Patrick Stewart plays 💩. In the last couple of years marketers have started using these smiley faces in email subject lines and push notifications, hoping to increase open rates by making their messages stand out.
In the spirit of continuous app store optimisation (ASO), we decided to find out ourselves if we could increase our downloads by adding emojis to an app’s short description in the Play Store. We decided to specifically test the short description as it’s seen by the most visitors.
Adding the 🚀 emoji to the short description increased downloads by up to 20% in Germany.
Thanks to the integrated A/B testing tool in Google’s Developer Console, hypotheses such as “emojis in the short description generate more downloads” are easily testable.
After we identified the emojis we wanted to compare ( 🚀 🚮 💯 ), we set up a multivariate test by adding these variations to the existing short description. We didn’t change the copy or any other aspects so the emojis would be tested in isolation to give the clearest results. Then we ran localised tests in several languages to see if our findings were consistent.
Each variant was rolled out to 16.6%-25% of visitors. Based on the impact of each variant, the tests would then run for between two and seven days. The exact length of the tests is determined by the Google testing tool, which decides when it has gathered enough information to form a conclusive result.
We ran this test in eight different languages and saw positive results in 50% of the languages/countries.
Using emojis in the short description had a significant positive impact on downloads in Germany [German], Italy [Italian] and Poland [Polish] of up to 20%.
Winner in Germany: 🚀
Winner in Italy: 💯
Winner in Poland: 🚮
In English speaking countries on the other hand, the original short description generated more downloads than the versions with emojis.
There is one caveat to these results: we haven’t (yet) localised the English language listing so all English-speaking countries see the same version.
Once we are able to break out the different countries we can explore the differences further.
Winner in English: No Emoji 😢
Some of our tests returned inconclusive results. This means the differences were too small to get a clear indication on whether emojis had a positive or negative impact on the download rate. These countries were Russia, Spain and France.
Results in Russia: 😕
Results in Spain: 😕
Results in France: 😕
The key take-aways from these tests are:
By constantly optimising and testing the Play Store listing, we have increased our global conversion rate (view / download) by over 4.5%. This translates into hundreds of thousands of new downloads and paying customers.
Time to start optimising and testing your listing! 😉
We've split our US listing into several regions and tested the effects on Emojis in the UK's listing with positive results! With the 🚀 emoji, the download conversion went up by up to 7.1%!
