I would like to know how many pages Google has indexed from one of my folders. Is that possible?? I tried doing a site:domain.com/folder check and I get an error message
Huh? what? Your asking me how to figure out the number of pages. When i replace -word= with the name of my folder i got all my pages that are listed in Google for that particular folder. But i guess you mean something else.
I didn't understand what you were saying, but anyway I was right, you can do site:domain.com/folder check, I was just typing the wrong folder
