Welcome to the Q&A Forum

I would recommend reformatting the Urls for  pages that have lost rankings. Then, just choose a few of the pages that retained their rank to try hyphens instead of + sign. Track them. If they improve, then do the rest of them. If they decline, remove the 301 redirects and return them to what they were and leave the rest of them as is. Dana

Hi David, When you click for additional information, it shows title, meta description, and meta keywords, so I assume that this error is referring directly to the meta title, not an on-page title. Any help is appreciated!
