I have an old archived site with tons of text content. I did a google search, and the text does not exist anymore in the search and it shows as results not found, this is after using the   operators.Can I use that text and put in on my new website (new URL) or will Google see it as duplicate content?
I had an old website with tons of content that is offline, can I reuse the content for my new site?
content
I use content from my older sites offline many times , I just had to wait for the old pages to de index , had no issues. Sometimes I had to request pages removed but patience is best.
