On the other hand, some of them might have had a very suspicious history with possible back marks stamped by Google. The domain that you wish to buy may have been linked with uncontrolled spamming. Google also has the habit of deleting some domains from its index, because of black hat methods used by the previous owner. Google cache tool is a very good tool that tells you whether the domain you are planning to buy had a ranking in its previous avatar.

3. The quality and merit of incoming links are also very important for a domain expiring. Organic links are always preferable to the ones that do not come directly to the domain. Organic links are those that originate from other web sites, which have very good search engine site index value.

4. The age of expired domain is another important indicator. You will also need to know who created that domain and when. Longer the life span of an expired domain better will be the commercial value. WHOSIS database is a very good source to know the origin of a domain expiring, and who created it and owned it and how long the domain was in use.
