Google Sites is a great tool for intranet sites and websites (hence the name ;-) ) if you can work with the structures and layouts Google provides.
Sites is easy and intuitive to use, integrates with GSuite apps and features attractive designs that look great on any device.
That’s why we consider it a great tool for your internal network, facilitating a one stop shop where all the different services you use are linked, easy to find and allow you to communicate with your employees and empower them to access the correct documentation etc on their own. Google’s underlying power of search, makes this even easier.
