The first clear difference you should be aware of is what you need to have a clearnet website, and a darknet website:
-To self-host a Clearnet website, you need you need a home server, elecricity, an internet connection, to port forward the website somewhere (on your home router or on a paid VPS), to make it accessible from outside your netwowrk, and a clearnet domain which is also paid.
