What would move?
Paste the address of the site you have now. We read it with the same reader our import runs on, so this is what would actually come across - and what would not.
No account, no card. One page is fetched, nothing is stored.
Questions
What an import protects is your ADDRESSES, which is the part most moves get wrong. Each page is rebuilt at the same path it had, and anything that does change gets a permanent redirect, so a link somebody else published still arrives somewhere. Nobody can promise what Google does next - rankings are its decision, not a setting - but a move that keeps its URLs is not asking it to start again.
Anything behind a login. Your current platform's own apps and plugins, which only exist there. Form submissions and order history already collected. Email accounts on your domain. And the domain itself does not get copied - you point it at the new site, which is a change you make once at whoever sold it to you.
Because this is a question, not a migration. It reads the address you give and counts the internal links on it, which is exactly how the real import decides what to visit - so the number here is what would be attempted. The import itself then fetches those pages.
Same reader, different depth. This tells you what is there; the import at /import rebuilds it into a working site you can click through before you decide anything, with no account and no card.
No. An old site usually imports better than a new one, because the content is plain and the layout is simple. The reader is looking for your words, your prices, your photos and your contact details - not for good design.
