I am working to restore a website that crashed several years ago. There were several thousands of pages on the old site, and most of them have been restored. The site crashed so long ago that of course none of the pages are indexed in Google. I'm worried that when I restore the site, Google will slap it, or mark it as spam etc because of the sheer volume of new pages... a good number of the pages aren't high quality. Is there a way I can warn Google about this, or a smart way to go about this?
