Sorry if this is a stupid question as this is outside my field of work, but how can you tell if your page has been successfully indexed or not?

See https://www.google.com/webmasters/tools/ for index stats, error reports, etc.

Just search on google for "site:http://www.yoursite.com" and you can see the pages it has indexed.
