This is a domain I might have bought when I was new into domain investing, but now I would have passed on it.
At first glance, it seems like it may be a good buy because the Age and history.
However, when you break it down piece by piece, it's one of those domains that will earn very little in PPC revenue (because the backlinks are old/outdated), and most likely will never sell to an end user.
The reason is from a branding standpoint, FindaPetonline is a long-tail, 4 word, 5 syllable and any company with a budget is going to choose a shorter, more premium brand for their business.
If it was
www.FindaPet.com then you would have a winner.
The big clue, is "findapet" is registered in 17 extensions, whereas "findapetonline" is only registered in 1.
I have 20+ similar domains I have acquired over the years, traffic domains with backlinks, but not great brands, and have only sold 1 that was on payment plan and then cancelled. AI has analyzed my portfolio and says these types of domains are "Dead weight" and affecting total STR.
