I have one website 3 years old hitted by Google update. I let it die, so I don't know if it was penalized or google just stopped going through, I passed from 500 daily users from Google to 20 daily users.
I changed all content, added some new fresh text, changed some external links with no follow and add new internal links.
I also added Facebook page and modified a bit my kw density in the posts.
After this I redirect 301 to a new domain .it, so passed from a .com to a better tld .it and I created new GSC for the new domain. Added sitemap, robots etc.
I did all correctly?
