Hosting
Where the site’s files live. It can sit with your provider, as long as you get access on request and know where the backups are.
Why it matters when you read an offer
Only two questions on this topic are worth asking: where the backups are, and when a restore from them was last tested. Everything else is detail.
What it looks like in an offer
Hosting included, with no amount and no term. Ask what it costs after year one and whose name the account is in.
