Since links are so important to search engine rankings there is a strong incentive for website owners to to increase their links An owner may generate hundreds of dummy websites containing little relevant or original content, They would have backlinks pointing to their main website or inter-links between the sites. The cost and time of running this ranking method would be greatly reduced if the owner hosted all of these websites on the same server (host).
Does this method work?
This type of scheme probably worked for a while, but over time the better search engines identified and discount the culprits. Search engines can check to see if the inter-linking websites are hosted on the same IP or IP address range. If the web sites are in the same IP address, it is highly likely that they are operated by the same individual. Search engines devalue links from web sites pointing to other web sites hosted on the same IP address range. They may make exceptions for large shared sites like Blogger.
The Ideal Links
The search engines (especially Google) are very good at identifying sites that are trying to game the system. When building your links you should try to keep our link profile clean. First of all, links to your website should not have inter-linking websites from the same IPs.
Ideally:
– the links should come from different class C network addresses.
– the domains should be registered with different registrars using different names.
– the sites should not use the same template or have large chunks of similar text.
– the acquisition of your links should come close to a natural link profile.
Following these principles when link building will help ensure that your links are counted and your site is trusted. Going too far the other way can result in low rankings or penalties.
