-nofollow to find websites where links are dofollow and he claimed that this query can exclude websites whose HTML source code contains
Well, personally I've tried a couple of times with
-nofollow but still can find nofollow websites.
I can't help but wonder, does it work for real?
According to this support page:
Add a dash (-) before a word or site to exclude all results that include that word.
In other words, does "results" include HTML source code?
