You have started a blog, that is AMAZING. But how do you know how many people are visiting, what pages are being viewed the most, and if your readers are male or female and their age range?
You need something much more sophisticated than the built-in analytics such as Jetpack Site Stats in WordPress or the Stats in Blogger.
Google Analytics is my go-to web analytics tool. I use it, and have used it, on all of my blogs.
It gives you insight into the traffic on your site including your audience, how people get to your site and how people interact with your site such as what pages are the most popular landing pages and what pages are the most popular exit pages. With this information you can make meaningful and informed decisions about your target audience (such as are you attracting who you thought), what channels to spend the most time on (aka what channels are providing the most traffic), and even what pages are your trouble pages and need to be fixed (aka pages with an extremely high bounce rate and low average time on page).
Google Analytics is a very powerful tool in your blog and business. But, in order to use it you of course need to install it!
I will walk you through creating an account, installing it on Blogger and installing it on WordPress.
