Seeing Traffic Boosts by Employing C-Block Links
Is linking between IP addresses on unique CBlocks really better than links between unique IP addresses on the same C-Block, in hopes of an SE traffic boost — and will this technique help you in the real world?
“Yes and no” may be the right answer ...
The reasons for this include the fact that if you are worried about C-Block linking and its impact on SEO, it means that you are likely operating more than one website and that these multiple sites, if not outright sharing the same content, are very “similar” in nature — even if this similarity is only in the perceived “voice” of the publisher. In other words, placing the same content on several websites, that are perhaps only distinguishable from one another by unique domain names, graphics, background colors or other insignificant differences, will be seen by Google for what it is — a spam farm — regardless of how many C-Blocks are being used.
In other words, your blog network of 1,000 sites echoing the same sponsor RSS feeds won’t likely see any measurable SEO benefits from being split across unique C-Blocks.
Another factor in this is “ownership,” something that search engines easily evaluate via domain registration information. For example, your company is listed as the owner of three domain names; each of which is on a separate C-Block in an attempt to boost search engine’s perception of the value of the site’s interlinks. Registration info is part of many search algorithms, however, so the transparency of this “trick” is obvious to Google, et al.
Think you’re clever by using private registrations to try to get around this?
Those same algorithms may be discounting the value of commercial websites using private registrations — as those companies seem “unwilling to stand behind their offer,” as evidenced by their obfuscation of ownership and contact details — turning a potential ranking gain in one area into a loss in another.
Companies (and subsidiaries) are easy enough to start, however, so if you’re serious about maximizing the effectiveness of a small network-building trategy, having a unique holding company name and address for registering each domain name, and then putting those new sites on different C-Blocks, may work really well for you.
Just keep in mind that the very nature of what you’re trying to do is seen by Google as “trying to game the system,” so when you’re caught, don’t be surprised at the results.
