My Google rankings dropped over the past month and I have found out that it's due to duplicate content on my website. I blocked the duplicate pages in the robots.txt file and I'm now wondering how long it will take to recover. Google isn't very specific about this in any of the reading I've done, so I'd like to get some opinions from people who maybe have experienced the same thing. The duplicate content on my site came from an entire section. I blocked the URL pattern so Google can't crawl it anymore. Please let me know if you know anything.
