These days webmasters are in a phase of rush to get back links for their website. Why? Very simple answer; they need better rankings by achieving better link popularity. In this race some webmasters forget that search engines also care for quality of backlinks. Now what are quality backlinks and how a webmaster knows that the links gained by him are quality ones in the eyes of search engines? This is all seo gurus have been quarreling over. Almost all people have different opinions on search engine ranking methodologies and their way of analyzing backlinks.
Apart from this ongoing discussion on quality of backlinks, one thing on which all seo masters agree is the quality of backlinks which comes from same IP address. It is not considered good by any means. Though all websites on same server having shared hosting own same C class IP address so linking to these websites in not a good idea.
Now what is this C class IP address and how it can affect your search engine rankings?
Just take a simple example to understand this C class IP address. IP addresses come in this format. 111.222.333.444 Here the block in No.3 place is known as C block of IP address. Webhosts are always issued different C class IP addresses, so if your websites are hosted on different webhosts then most chances of getting different C class IP address. But in some cases two webhosts take reseller web hosting from same hardware owner so there is a chance that both of them are on same C class IP.
What is the impact of C class IP in SEO?
To make this long story a bit shorter, here is the example of two webmasters having same C class IP address.
202.192.168. 306
202.192.168.104
Now an example of different C class IP addresses.
292.164.111.243
292.165.222.306
Why search engines degrade links from C class IP? Very simple, in first set of IP addresses a relationship is very prominent among websites, whether it is due to web hosts or actually these are on same server but search engine like Google are very good in detecting this relationship so links from such relationship basis are not considered good. But remember this not a fix for any thing. Many sites rank very well in search engines having same C class IP. It is not something you have to worry at start but it is just an issue of information regarding better search engines techniques as better results can be achieved by focusing on such minor issues.
