Hi there, I recently updated the titles of almost all of my pages because Google was rewriting the titles for me. I made the titles a lot more concise and dropped any repeated keywords. But I've also been playing around with them an awful lot...multiple title changes over the course of the last month or so. Nothing has stopped Google from rewriting the titles, but this morning I notice that I plummeted for some searches that I have been at the top for for many years. I was in 1st-3rd place this weekend for some terms and now I'm at the bottom of page two today! I'm afraid I've triggered some kind of penalty by making changes to all my titles at once. Another change I made this weekend was adding the rel=canonical meta tag to specify the url on each page. I have been having dupe page title and desc issues so though that might help. In WMT I noticed a big sudden drop in dupe page titles, down by hundreds of pages to only 30 now. I would think that would help not hurt...Any advice on this?
