Have you ever noticed that some websites have a little green lock symbol to the left of the address? Like this:
That means that the traffic to that page is encrypted and that the data communication is protected from people trying to spy on what you are sending and receiving.
By creating your website with Pageup your site will be protected, using certificates from Let's encrypt!.
This is also a signal to search engines like Google that this page is more trustworthy, and so gets higher ranking than pages that are not protected.
So why not go ahead and create a protected website right away!
