One night, I thought I should check to see if Google might have found it and indexed it on its own. So, I typed the "site operator" (site:mydomainname.com) into the address bar to see if Google had any record of it.
No results were found.
The next morning, for some reason, I had a feeling that I should check again -- which I did. The result: all the pages of my website were indexed.
Now, I am not saying that Google indexed it for that very reason, but I am guessing it wasn't a coincidence.
