I'm trying to host my website from my Raspberry Pi 2 which I will be using as a headless server that I will ssh into. I want to install Ubuntu on it.
Should I use this download link which is from the Ubuntu for Raspberry Pi webpage?
Or should I use this one from the Ubuntu Server installation page?
I am also unsure what the differences would be and would like to know what they are.

Raspberry Pi preinstalled Ubuntu 20.10 Desktop and preinstalled Ubuntu 20.10 Server images are available from ubuntu.com. The preinstalled images allow you to unpack a preinstalled version of Ubuntu onto a target device.
Download the first link in your question. It is the official Ubuntu 16.04 image for Raspberry Pi 2 at the ARM/Raspberry Pi - Ubuntu Wiki webpage. The instructions for installing this image are at the same webpage.
