Okay kiddo, let me tell you about mobile web analytics. Have you ever played hide and seek with your friends? And you had to keep track of who was "it"? That's kind of what analytics does for websites on your phone or tablet.
When you look at a website on your phone, it sends information back to the people who made the website. They use that information to see how many people are visiting their website, which pages are the most popular, and how long people are staying on the website.
Just like when you play hide and seek and the person who is "it" tries to find where everyone is hiding, website creators use analytics to try and find out what their users like and how they can make the website better.
It's like a game of detective where they look at clues - or data - to try and figure out what's happening on their website. They can use this data to make changes to the website, like making it easier to use, or adding new features to keep you coming back.
So, mobile web analytics is basically tracking how people use websites on their phones or tablets so that website creators can make it better for you!
