Welcome to the Q&A Forum

In order to eliminate duplicate/missing title tag errors for a directory (and sub-directories) under www that contain our third-party chat scripts, I added the parent directory to the robots disallow list.

We are now receiving a blocked resource error (in Webmaster Tools) on all of the pages that have a link to a javascript (for live chat) in the parent directory.

My host is suggesting that the warning is only a notice and we can leave things as is without worrying about the page being de-ranked/penalized.

I am wondering if this is true or if we should remove the one directory that contains the js from the robots file and find another way to resolve the duplicate title tags?

My crawl diagnostics shows roughly 20+ pages with missing or empty title tags, however, the titles are viewable through the source code and there is only one instance of it on the page. This is not a wordpress site nor are the titles extremely long. Would there be any other reason for the crawl tool to not pick up these titles?
