Google Analytics, can help you answer important questions about your website visitors. You can use it to find out where your visitors come from, what pages they visit, how long they stay on your site, and what conversion rate you're getting. SEO can also be looked at through Google analytics as well.
This information is valuable because it can help you make decisions about how to improve your website. For example, if you see that most of your visitors are coming from a particular country, you can focus on marketing to that audience. Or, if you notice that people are spending a lot of time on your pricing page but not converting, you can try changing the design.
Additionally, Google Analytics can connect to your AdWords account so you can see how well your advertising is performing. It can also connect to additional platforms so you can easily move analytics from site to site.
Google Analytics is a free service, and it's easy to set up. Just create a Google account, and then sign up for Analytics. Once you're signed in, you'll be able to see all of your website's data in one place.
