It looks to me like Google has, just recently, remove the link: search operator on Google. If you search for any website’s links using Google, there aren’t any search results. So, for example, a search for link:google.com shows no results:
So, most websites (or the main ones I have tried) show no results if you try to look up the links to a website in Google.
But, if you were to use the Link: search operator, if you use the Capital Letter L in Link: then you will find results, but it’s pretty much useless, as it’s just a search result including that site you looked up:
So, I am going to go ahead and call the link: search operator dead in Google. It has been for at least, well, let’s say at least 5 years or more, but now it’s useless. As in don’t use it, it doesn’t give you any results, and Google doesn’t want you to know the links to a site because links are still a part of their algorithm.
By the way, it’s worth noting that Google does NOT list the link: search operator on their help page here:
