A “campsite” is a relatively flat and relatively root/stump-free patch of dirt. That’s it. Also tents are generally not made out of the canvas material you linked that yurts and teepees might be made from.

Tents are generally made of a very wuick-drying, thin synthetic.

And like the other person said, this does make it seem like you’ve potentially never been camping but i don’t want to gatekeep the definition of “camping”. My version is carrying everything I need on my back for two weeks and walking 10-15 miles each day to the next campsite (read: “patch of dirt”, preferably near fresh water). Other people “camp” in RV’s though, so.

Camping is just the bit about sleeping at night. I’d call your version hiking/walking/backpacking depending where I am.
