The files and data that are your website are hosted on a server. This server is connected to by Internet Protocols or IPs. Every computer on connected to the public Internet has a unique IP, typically looking like this:

758.71.35.420

As you can see an IP address is communicated with sets of numbers seperated by decimals. IPs are separated onto different blocks, designated by their hosting provider.

Class C IP Address

There are five classes of IP ranges. Class A, B, C, D and E. Each class allows for a different range of IP addresses.

The sets of numbers in an IP, are split into two sections: Net and Host. The Net section contains the first set of numbers. It’s used to identify the network that a computer belongs to. Host (sometimes referred to as Node) identifies the actual computer on the network. The Host section always contains the last octet. There are five IP classes plus certain special addresses. The one we’re talking about is again, that Class C.

Class C addresses are commonly used for small to mid-size businesses. For our terms, an octet is a grouping of eight bits. IP addresses with a first octet ranging from 192 to 223 are part of this class. Class C addresses also include the second and third octets as part of the Net identifier. The last octet is used to identify each host.

Class Address Range Supports

Class A 1.0.0.1 to 126.255.255.254 Supports 16 million hosts on each of 127 networks.

Class B 128.1.0.1 to 191.255.255.254 Supports 65,000 hosts on each of 16,000 networks.

Class C 192.0.1.1 to 223.255.254.254 Supports 254 hosts on each of 2 million networks.

Class D 224.0.0.0 to 239.255.255.255 Reserved for multicast groups.

Class E 240.0.0.0 to 254.255.255.254 Reserved.

Why is Class C Important?

Search engines take a close look at the servers hosting your site. To combat spamming, sites on the same server are viewed as being on the same server. Search engines have removed linking power from one site to another if they are on the same class C IP.

In other terms, two sites on the same host will only be as powerful as one. While there is no penalty, there is a deteriment to their power to help each other.

When conducting your search engine marketing campaign ensure you are persuing links on sites with unique class C IP addresses for maximum promotion power.

“SEO Book is a leading SEO blog by Aaron Wall covering the search space. It offers marketing tips, search analysis, and whatever random rants come to mind. The first version of my popular SEO Book came out in December of 2003. I have probably revised it about 50 times since then.

Balancing answering emails, blogging, reading blogs and forums, buying and developing sites, working for a couple customers, and running this site is pretty hard – especially with only a couple employees.

In the past SEO Book was more about posting search news, but since the market has got so saturated on that front and I acquired the Threadwatch community I have decided to keep Threadwatch focused on the latest search news and speculation, and to use SEO Book to answer customer questions and to offer online marketing strategy tips. In 2007 I decided to shut down Threadwatch to focus more energies on improving this site. Shutting down Threadwatch has meant that more of my whinges have wound up on this blog, but then so have many of my best posts.”

This great resource covers everything from coming up with a business plan, and deciding on a brand and domain name, to marketing your website and succeeding online.

Importance of Building Quality Links

All the content in the world will not rank your website if you don’t have quality back links pointing to your site. Building back links and staying afloat of competition is an on-going effort. Generally sites in the top 10 for competitive terms will have thousands, sometimes tens or hundreds of thousands of links pointing to their site.

Links that best help your site would be .edu, .org, and .gov if you can find them. Factors to consider in persuing a link on someone’s site is the age of the domain, links pointing to their site, and the Google PageRank to get a rough idea of a sites ranking power. You should also make sure that the link to your site is not ‘no follow’ which will kill any kind of promotion power you may have gotten.

Types of Links

Organic Links: “natural” links that are created thanks to your quality content. Organic links are created by users who enjoy your site and do the work for you by posting your link on forums, sites, and sharing with their friends.

One-Way Links : generally purchased, these links are from one site pointing to another. These include paid listings on websites, and directory submissions. One-way links are the largest carrier of ranking power from one website to your website. Some good one-way links can be obtained through relevant-site press releases.

Reciprocal Links : exchanging links is unfortunately a dying practice. There was a time when you were encouraged to exchange links with someone, creating a reciprocal link. Reciprocal linking now a days is best left to relevant websites. The days of exchanging links on your links page have come and gone. A good amount of bloggers will create profiles on sites like Facebook and Myspace, and link between their site and profiles.

Three-Way Links : so say you want the benefits of a one-way link, with the practice of a reciprocal link. You may consider a three-way linking set up, where the owner of site A would link to site B. In exchange, the owner of site B would link to another site of site A owners’. These aren’t detected by search engines as connected if done right.

For getting first page search results consider submitting to the Google DMOZ directory. DMOZ is an aggregater for many other directories, providing the listings they will use which will further promote your site without any additional work.
