We are moving our website to a new CMS, and working with a vendor who would like to change the title tags from the current format to a breadcrumb structure. Our fear is that this may negatively impact the current optimization efforts in place. Our current title tags are a mixed bag of good, bad and neutral, but some have been optimized for best practices. Does anyone have any insight on the effect we would see if everything were changed at once, or any suggestions on how we could test this before we launch the "new" site?
Thanks!
