I'm a bit confused at the moment. I'm working with some web 2.0 backlinks and want to know if they are indexed or not. I've always been using site:MyURL and if the site shows up I've considered it to be indexed and if not then the opposite. So I tried it today for a new web 2.0, site:MyURL1 and the site didn't show up. But I read somewhere to try just "MyUrl1" (with "") and with that search query the site showed up. I've also tried some recommended index checkers, and those can say that a site is index even though it doesn't show up with any of the search queries above. So how do I know for sure if a site is indexed or not?
