The IP popularity and domain popularity each play a part in the overall quality evaluation. If you come across an expired domain with a high link popularity (i.e. a large number of backlinks), but then poor values when it comes to IP and domain popularity, you can assume that these links were obtained in an artificial way. Domains like these will have already caught the search engines’ attention. Perhaps this is the reason why the domain was abandoned. Users that want to start a serious online project should steer clear of these domains.
It's ranking high today! What could be the problem? NO. JUST STOP. Unless you know the entire history of a domain, you may be setting yourself up for failure before you begin. SEOs (and business owners) use a variety of tactics to get a site ranking high in search results. For some of these methods, we'll just call them "questionable". These methods could include everything from buying links, overuse of directory submissions (non-industry related), duplicate listings, poor quality backlinks, and guest blog comments.
Most of the website owners interested in an expired domain that has existing traffic, backlink and good SEO metrics. This kind of domain more likely gets buyer easily since it has a plus value for search engine optimization purpose.

Let’s just say for example we wanted this site, crystalgiftsworld.com. It looked good based on our analysis and we’d head over to Snap Names, Nameja is another one and what these service do is they have special technology on their site that allows them to try  to register a domain on your behalf over and over again. Okay? If you tried to do that your IP would get banned, but they have some system where they know how to do it just enough to get the domain, but not enough to get blacklisted.

So how do you develop that instinct? NameBio maintains a database of over 500,000 historical domain sales (as of writing this post).

Simply sifting through the listings on NameBio long enough will quickly develop your domain appraisal “instinct”.
