I did this once before, but can remember where I found it. It sent a crawler and counted my pages.
Try website grader they will tell you how many pages are indexed with google, as well as other helpful information about your site. I hope this helps.
Good Luck! R
Thanks. Not sure how accurate that is, but it is a start.
Search google for “site:example.com”. A list of all the pages they have indexed will be returned to you (which should be every page unless there are any not existing in a link chain).
