Google spiders it twice a day, but does not show up with site:----.
I bought the domain from namecheap. I found the site had a history, but nothing serious. It was registered and never used (found it on a forum that lists expiring domains). Nothing in wayback machine. I always thought domains from registrars were never registered (like new cars).
Then I read about sites getting indexed within a few hours. I can see a week as reasonable time.
Seems like a game of luck?
