How does Google Analytics authenticate a website?

Google Analytics authenticates a website by using a tracking code that is placed on every page of the website. The tracking code is unique to each Google Analytics account and is generated when you create a new account or property in Google Analytics.

To authenticate your website with Google Analytics, you need to follow these steps:

1. Sign in to your Google Analytics account and create a new property for your website.
2. Copy the tracking code provided by Google Analytics.
3. Paste the tracking code into the HTML code of every page of your website, just before the closing </head> tag.
4. Save and publish the changes to your website.

Once the tracking code is in place on your website, Google Analytics will start collecting data on your website's traffic and usage. This data can then be used to analyze your website's performance and make informed decisions about how to improve it.
