Experiments @ Twitter

As we’ve talked about before, we’re constantly working to make it even easier to follow what you care about, connect with people and discover something new on Twitter.

To that end, we are constantly evolving the product. Some changes are visible –– they may help you protect your Twitter account or make it easier to share photos; others are under-the-hood changes that help us suggest relevant content in real time and make Twitter more engaging.

A common thread across recent releases has been experimentation. We’ve tested various features with small groups of our 200 million users before determining what we’ll release. These tests are essential to delivering the best possible user experience.

It’s rare for a day to go by when we’re not releasing at least one experiment.

We also experiment with features that may never be released to everyone who uses Twitter. Those experiments are perhaps even more valuable because they help us decide what not to do –– which is important as we work to keep Twitter simple while improving the user experience. Ultimately, our goal is to learn and keep making the product better; we aren’t necessarily looking to launch all of the experiments we roll out.

In recent months, that trend has picked up –– so much so that it’s rare for a day to go by when we’re not releasing at least one experiment. We’re able to run tests more frequently because we’ve built a more robust experimentation framework, which we use to run tests not only on the web, but also in our mobile apps: Twitter for iPhone and Twitter for Android. With the majority of our users accessing Twitter from a mobile device, it’s important for us to be able to test on mobile. Over time, you’ll continue to see us test and introduce new features first on mobile. For example, we recently introduced the people button which suggests accounts for you to follow.

So what does this mean for you? You may see some features that your friend doesn’t see, or vice versa. This is all in service of making Twitter the best it can be. We appreciate your help in doing that, so thank you.
