The spirit of experimentation and the evolution of your home timeline

Tweet

As we’ve shared a few times, we constantly try new experiments around here, which serve to inform the evolution of the product. We believe that each successful experiment, big or small, can make your Twitter experience simpler and more relevant to you.

One of our goals for experimentation is to continue improving your home timeline. After all, that’s the best way to keep up with everything happening in your world. Choosing who to follow is a great first step – in many cases, the best Tweets come from people you already know, or know of. But there are times when you might miss out on Tweets we think you’d enjoy. To help you keep up with what’s happening, we’ve been testing ways to include these Tweets in your timeline — ones we think you’ll find interesting or entertaining.

For example, we recently ran experiments that showed different types of content in your timeline: recommended Tweets, accounts and topics. Testing indicated that most people enjoy seeing Tweets from accounts they may not follow, based on signals such as activity from accounts you do follow, the popularity of the Tweets, and how people in your network interact with them. These experiments now inform the timeline you see today. (See our help center to learn more about what’s in your timeline.)

Some timeline experiments never make it to 100% of users. The ones that do aim to make the experience more interesting and relevant. As the timeline evolves, we will continue to show you Tweets you care about when they matter most.
