Just like any other platform, you can integrate Google Analytics with Squarespace. In Squarespace, you have to go to settings -> Advanced -> External API Keys, and you will find a textbox to enter your Google Analytics product ID. Enter your ID in that textbox, and your Squarespace website will be connected to your Google Analytics Account. You can also integrate other tools into your Squarespace website by adding the code in the header or footer based on the instructions.
