The first thing you need to know is what an expired domain is. An expired domain is a domain site that has been left to expire. The original owners decide not to renew the expired domain for a lot of reasons, including incurring penalties from Google. They are auctioned off to the highest bidder, so to speak. Now, not all recently expired domains are worth the investment. You may assume you are getting a great deal, but are you really?
Time to explore recently expired domains further!
1) You need to look at how old the site is. There is an old saying, “old is gold.” The older domains have more of an advantage when it comes to SEO uses. An older domain site has to match your traffic niche though. It does not make sense for an e-commerce site to invest in something old that has nothing to do with their brand or product line.
A Good Rule of thumb: A site needs to be at least 2-3 years old. It also cannot cost you a thousand dollars or more to repair.
2) You know how your body needs a shot of energy every so often? Your site does too. That is why backlinks exist, but you need the good stuff. Websites with backlinks get more attention than those that do not. You need to buy your backlinks through legal means. In other words, the black hat tricks are dead and buried. They do not work, so do not use them. Sites that attempt to use them are going to be penalized by Google.
Buying expired domains can be a challenge. Old domains with attachments to illegal backlinks are not tolerated by Google. Google has tools you can use to check an old domain. That way you know whether the site is legal or not. That may be one of the reasons why it was left to dry.
3) You need to check that Google has not banned the site before you go buying expired domains. Google has gone as far as banning sites that rank high in page inquiries. Google is going to ban the site if it used any black hat tricks. Check the site first before you insist on buying it.
SEO Mastering/Search Engine Genie: Two SEO tools you can use to verify whether or not the site has been banned or not.
4) Users do not use the page ranking feature anymore because it is dead. They use the domain authority feature. It is a tool that helps you to verify what pages and sites rank the highest and why.
Moz Tool: This is a tool you can use to verify the ranking of the site, expired or not. Your scorecard should read more than 20, while the spam score should be less than 3/17. That should give you an idea of what you are looking for.
