It also depends what the backlinks are like. Certainly it's great if there are a lot of linking domains (and the number of overall links isn't disproportionately different to the number of linking domains). But some of those links might be great, whilst others might be garbage.
You can get three really nice articles (1,000+ words written by a proper PR person, not a link builder!) posted across three really nice sites (with DAs ranging from 65 to 80+) for about £700 GBP / $890 USD. You have to figure that, since those are one-time posts, the value of each containing site must be significantly higher (in the thousands or tens of thousands of dollars)
When prospecting websites as potential link opportunities, I also look into tools like SEMRush or Ahrefs which give estimated traffic figures for those websites (although the traffic estimates are usually only estimates of what those sites take in from Google). I would certainly do the same thing in a lot more detail if I was going to be buying a site rather than a one-off placement. Some tools give even better traffic data for 3rd-party sites which they buy from ISPs and build a front-end around that Also you can get Best SEO Services from SEO Expert in Lahore
