Last year I bought an old domain, registered in 1997. It's keyword rich, as you'd expect from a domain of that age. Old school backlinks, ahrefs has a domain authority of 27. It's had relevant content on it since new, other than in 2023 for a while it had a wordpress holding page.
When I bought it, I moved it from the US to Canada hosting, and loaded it with a nice new look and a bunch of high quality relevant content.
I don't expect it has a manual penalty (if those things even exist any more). I did expect that once I put up some great content on some long tail terms, that in six months to a year it would pop back into the rankings. Unfortunately, nothing. No results in the first 10 pages.
Suggestions on next steps? I was looking for an easy win here, the dream of just putting some content on a website and having it rank old school.
