SEO Link Building: The Myth About Getting Links From Classs C Network
Friday, February 27th, 2009[ad#large_rect]
When you read most SEO blog posts, or freelance jobs requirements, they will say, the links must be:
- Have Google Page Rank 2+ on the Link Page
- Relevant to the sites
- No more than 30 outgoing links
- No javascript … blah blah blah…
- Links from Class C IP network
I am no problems with others but Links from Class C IP network!?! I am shocked! Why?
Links From Only from Class C IP Network is a myth!
What is an IP address anyway?
Before I give you the reason, let’s look at how today IP addresses work. The existing still in used IP address network is called IPv4 where the computer network industry categorized it in to 4 classes of network, named A, B, C, D and E. With Class D and E are reserved for something else. Which leaves A, B and C widely used nowadays.
A typical IP address consists of 4 octects (bytes) or groups of binary numbers (0 or 1) such as with the decimal notation of 123.27.117.89. Being 123 the first octect, 27 the second, 117 the third and 89 the forth. By definition, each group of numbers can only starts from 0 and ends with the maximum number of 255. So we classify class A network (only consider the first group of the numbers), starts from 0 – 126. Class B starts from 128 – 192. Class C starts from 193-223. With the missing 127 is reserved for the local computer.
Only Counts Class C network?
Thus, if links from only class C IP network is going to count towards the Google ranking calculation, that means you have to get links ONLY from websites that have IP addresses start with 193 to 223 and that’s it! But I can tell you only a very small portion of the entire web have the class C IP addresses. You can do a simple check with a command called “ping” in your windows command prompt. If you are going to ping Google.com for example, you will notice one of their data center IP is from “74.125.67.100″ that is a class A network IP. If you tried Standford university, (standford.edu), one of their IPs is 171.67.22.33, a class B network. You can also try IBM.com, GM.com, Target.com etc. You will find there are really little portion of the Internet are from Class C network.
Therefore, if you only get links from class C network, links from IBM.com, GM.com, target.com are not going to count! Do you think this make sense? To me the answer is obvious.
So the conclusion, getting links from Class C network only is a myth! You can get links from any classes of IPs as long as they are unique. That’s the end of it.
I hope this article do clear up the SEO myth around. Sometimes I really can’t stand with so much misconception and that’s why you need to have a professional to work with your campaign, and do not attempt to do it all by yourself!
Thank you : )
