Geolocation Error on 7/9/2015

Incident Summary: No geolocation was being performed on events and people requests between 5:00PM PST 7/8/2015 to 1:30AM PST 7/9/2015. This affected all customers. Timeline: On 7/8/2015 at approximately 5:00 PM PST, a change was deployed to consumers that migrated our geolocation system from a Python module to a C replacement as part of our systems optimization plan. After this point, all geolocation requests made to the Maxmind DB began failing. Around 7/9/2015 1:00AM PST, Mixpanel began reverting the change and by 1:30AM, all consumers were reverted back to the Python Maxmind DB reader, which resolved the issue. Root Cause: The migration from a Python module to a C replacement proved not to be a direct drop-in replacement and generated errors (TypeError) when fed a value other than a string. We typically send IPs in the format we receive them, which can sometimes be a long...

A/B testing comes to Android

So you've got an idea. "We have all these awesome features most users just haven’t tried yet. I bet more people would use them if they couldn't skip the tutorial. " "I know more people would create an account if our button just said 'Get Started'." "Our game's too easy. People want a challenge. If it were a bit faster, it would keep users coming back." Great, but a good idea alone isn’t gonna cut it. Especially when opinions differ. What you really need is cold, hard data. You need to put that hypothesis to the test and see how it fares with real users in the real world. That's where A/B testing comes in. Previously, you've been able to use Mixpanel to experiment and improve your iOS app. And we've seen how useful it has been to our customers. Today, we're expanding Mixpanel A/B Testing to Android. All the capabilities that enable you to experiment and improve your iOS a...

Community Tip: Benefits & Best Practices for Cross-platform Apps

In this Community Tip, we highlight the benefits and best practices for accommodating all of your varied products, environments, and platforms under a single Mixpanel project. Using this guide, your team can decide how to best track your cross-platform app data within Mixpanel. If you're one of the many users working with cross-platform apps, you may have wondered whether it's best to combine everything into one Mixpanel project or split everything up and analyze it separately. We've found that creating separate Development and Production projects to avoid cluttering your Production data is a great best practice, but the question of what to do with cross-platform Production apps is a matter of preference. The good news: Mixpanel is flexible enough to handle cross-platform scenarios in any configuration you'd like to implement. The choice is yours, and each approach comes with its...

How Cozi got a 38% increase in signup completion

Tara Pugh, product owner of Cozi, stopped by our June Office Hours to explain the process for improving their UX through many small, data-driven steps. Cozi helps bring order to the chaos of modern family life with an app that gets the entire family on the same page with shared calendars, to-do lists, and shopping lists. Digging into their conversion funnel data with Mixpanel, they identified opportunities to improve user experience by streamlining the account creation flow. Testing hypothesis after hypothesis, Tara and the team at Cozi were able to incorporate bits of learning into the flow: lighter background, different calls to action, pre-populating name and email forms. No single change resulted in a huge increase in conversions, but all together, the improvements raised the signup completion rate from 55% to 76%—a 38% increase. Check out Tara's talk for all th...

Community Tip: How to keep properties consistent across client and server libraries

To unlock the full power of Mixpanel reporting when using multiple integration libraries, super properties should be maintained across each Mixpanel library. In this Community Tip we discuss how to pass data from the client-side to your server for custom super properties and Mixpanel's default client-side properties. Passing custom super properties As a refresher, super properties are client-side properties that are automatically attached to every event that a user sends to your Mixpanel project. Super properties make working with Mixpanel data much more convenient because you can create custom global properties that are omnipresent on all of your events. These super properties will be attached to each and every event provided the memory location (cookies in a browser, device memory in a mobile phone) of the super properties is not cleared. However, since custom super properties ...

Now you can hide events and properties

Keep stale event and property names out of your dropdowns. Mixpanel has long offered you the ability to hide events that you've decided are irrelevant or maybe just were typos from the very beginning. We’ve recently extended this functionality to let you also clean up the list of properties that you see when segmenting reports or creating custom events. Say your application tracked an an event called "ate" with integer property called "tomatos". Later you decided to fix the pluralization of this property name and renamed it "tomatoes". Even though you stopped sending events with the "tomatos" property, you'd still see entries for both “tomatos” and “tomatoes” in the dropdown list of properties on your segmentation report. By marking the property name "tomatos" as hidden , you can keep it from showing up in this dropdown and any other dropdown that lists properties. How to h...
