You can now see how your Twitter handle is performing via Twitter analytics. Before now, you had to rely on third party applications or other extensions to do the same job. However, now, similar to Facebook page insights (or more closely aligned to Google Analytics) , Twitter shows analytics for your Twitter handle.
In July 2014 Twitter did release analytics, but the catch was, it was only available to advertisers and verified users. This time though the likes of you and me can see Twitter analytics as well.
It’s got some nifty stats and is well laid out. It’s very basic at the moment but also an eye opener of how the tweets are performing, which was hidden upto now.
