As your user just took specific action on your site, it’s a good idea to track that as a completed goal. To do this, access your Google Analytics account, then click Admin > Goals. Once there, click “+New Goal.” That will open this dialog, where you will choose “Custom.”

Next, enter your goal description. For this example, we’re adding newsletter signup so we know later what we’re measuring.
Next, we define the destination that users will see when they’ve completed the goal we’ve defined.
Google Analytics usually takes 1-2 weeks to collect goal completion data, so check back and see how things are working.
