I Google-d for the key phrase “SEO Hosting” and I was impressed by the number of results that turned out. Apparently there are too many services that provide SEO Hosting. By what I understood is that these services provide ‘x’ number of C Class IPs for ‘y’ amount of money. The objective is to host each domain in different C Class IPs. The reason why website promoters buy such a package [for link building] seems obvious. Search engines, when considering the link authority of a website, next to the relevance and quality of the links that come in, they give importance for how many different IPs are linking back to the website.
This method of link building has been in practice for quite sometime now. If the domains on the different IPs were built with good relevance and quality they yield a very high link authority for the main website over a period of time. But there is some catch. Will this be an economical choice for the pockets ? Well, it depends. The cost of hosting 50 domains in 50 C Class IPs will be anywhere around $200. Adding to this will be the cost of buying these 50 new domains and the cost of the content effort on them.
Is there an alternative to this so that its lighter on the pocket ? Yes, the option is parasite hosts. Parasite hosting is nothing but creating blog posts on free blog hosting services. You will very well be able to create 50 sub domains [ like abc.blogpost.com, xyz.wordpress.com etc ] in 50 different free blog hosting services and link back to the main website from each of these. The cost buying the domains and buying the hosting can be avoided.
There is more that can be d
one with the parasite hosted websites. If a link spoke or a link wheel can be created among the parasite hosted websites, they will them selves yield more link authority among each other. This will create a lot of link juice.
There is some more .. If each of these pages that link to the main website are inturn bookmarked/shared/liked in many social bookmarking websites, then the weight-age of these back links increases even more.
Remember, the same linking strategies can be done with domains hosted on different C Class IPs too. While the major difference is the cost that is being saved by using parasite hosts, there are other things to consider. These free blog posts might not be as flexible as the hosted domains. Sometimes, the free blog hosted domain is ranking will high for a specific keyword. You might want to get leads directly from the blog itself, but the service will not allow such a thing. Many blog hosting services do not allow you to show your own ads.
While there are a few disadvantages like this with free blog hosting services, if your only objective is to build back links to your main or money website, linking from domains hosted on free blog hosts serve the same purpose as domains hosted on different C Class IPs.

Link building has become the most critical elements of search engine optimization. Without having massive link building, on-page SEO cannot going to bring results and webpage cannot attain higher position. I continue to think that link directories and article writing are the best ways to obtain inbound links quickly.
Solomon,
Thats true. Link directories and article writing are the best ways to obtain inbound links quickly. However with the recent changes to Google search algorithm [Panda Update as they call it] What I notice is that people who have done article marketing with non repetitive articles have avoided any decrease in their ranking. For people who have reused their articles in many article directories have considered the Google panda update as infamous. This is why even in the above said parasite host link building method, care should he taken to not repeat any content and one article needs to be used for link building in one parasite host only.
I need help. It took me 4 months to build up 100 wordpress blogs to point to my website. And now (amazingly) every single one of them are suspended and deleted permenatly by wordpress. How am I going to get backlinks if I get suspended? I was thinking of using and ip cloning service but if I build 100 blogs on another ip then won’t they also get suspended? What should I do?
Sarah,
One of the main factors that search engines consider to rank your website is link authority. Which is actually the number of qualified and relevant links that you receive for your website. However, the links also need to come come different C Class IPs. In your case you have built all the blogs in wordpress. There are high changes that all these links come from the same IP [Wordpress.com's hosted IP]. What you could do is create blogs in as many free blog hosting services and link back from them to your website. There might be many reasons why wordpress suspended your blogs. To help you, here is a list of free blog hosting services that I know.
