I just realized google never forgets a page. Let's say I remove my website today and delete my website and then reinstall it 10 years from now in a matters of hours all my links will reappear and my ranking will also reappear…
This is good and bad I think because what happens if you have an issue one day with your website ?
Does google never forget about your duplicate content pages for example even though you fix this issue with rel-canonical or meta-noindex or 410 ?
Or does it store those pages in some index that doesn't count for the ranking ?
