Top-level Domain (TLD)
Top level domains (like .com) are the extensions associated with domain names. For best ranking results, avoid uncommon top-level domains (TLDs). Like hyphens, TLDs such as .info, .cc, .ws, and .name are spam indicators.

4. Non .com Top-Level-Domain (TLDs)
When a webmaster registers a domain name, they will be given the option to buy additional TLDs. In order to maximize the direct traffic to a domain, it is advised that webmasters should only buy a domain if the .com version is available. Additionally, it is not recommend that SEO conscious webmasters purchase low quality TLDs such as .biz, .info, .ws, .name, etc. as a means of increasing traffic.
