This manual way is exactly what I would like to avoid since it's quite cumbersome when you have hundreds of indexed pages and looking for a couple of new pages pending indexing.Checking for indexed pages using Search Operators
Just copy the URL of your webpage from the address bar - then paste it into Google with either site: or info: in front of it. If it returns the webpage in the search results, it is indexed. If you get nothing back, it is not indexed.
