I have a quick question on the Google "link:" command. My site used to have many of its backlinks shown on Google using this command. The site has been around for 6+ years. Recently, I started noticing that everytime I used the Google "link:" command, Google would say that my "Search Did Not Match Any Documents".
Also, my website PR dropped from 6 to 4. I was wondering if these two issues were related? Does anyone know if this means that Google has invoked a penalty against my site?
Thanks in advance!
