Welcome to the Q&A Forum

First off, I just wanted to mention I did post this on one other forum so I hope that is not completely against the rules here or anything. Just trying to get an idea from some of the pros at both sources.  Hope this is received well.  Now for the question..... "Googlebot found an extremely high number of URLs on your site:" Gotta love these messages in GWT. Anyway, I wanted to get some other opinions here so if anyone has experienced something similar or has any recommendations I would love to hear them. First off, the site is very large and utilizes faceted navigation to help visitors sift through results. I have implemented rel=canonical for many months now to have each page url that is created based on the faceted nav filters, push back to the main category page. However, I still get these damn messages from Google every month or so saying that they found too many pages on the site. My main concern obviously is wasting crawler time on all these pages that I am trying to do what they ask in these instances and tell them to ignore and find the content on page x. So at this point I am thinking about possibly using robots.txt file to handle these, but wanted to see what others around here thought before I dive into this arduous task. Plus I am a little ticked off that Google is not following a standard they helped bring to the table. Thanks for those who take the time to respond in advance.
