If you have released your website or application to the public, it is very important to keep track of your visitors and their behaviors to see how your website is performing. Your ultimate goal would be to reach in to more users or customers and you need to see if that’s happening or not.
What types of analytics you can get
It can vary depending on the type of your application, and what types of integration you do. But most commonly, you can see the number of visitors, active users, how long they visit your pages and which pages they navigate to.
You can also see where most of the traffic is coming from and there geographic details such as countries they are from and devices they use.
Does is slow down your website or application
With today's latest tools and technologies, having an analytics integration does not slow down your website. While it does take up a smaller amount of your request times, but in most cases it is not noticeable.
