I've been meaning to make this post on my blog, but I thought I would just go ahead and put it on DP... Many people want to know how many one-way links they can build between their sites. The answer is simple: [(W x 0.5) - 0.5] x W whereas W equals the Number of Websites For example, if you would like to build one-way links between ten websites, simply plug ten into the formula: [(10 x 0.5) - 0.5] x 10 [5 - 0.5] x 10 4.5 x 10 = 45 Once you know how many one-way links you can create, you can use a simple grid to map out which websites to link together: 1 links to 2, 3, 4, 5, 6 2 links to 3, 4, 5, 6, 7 3 links to 4, 5, 6, 7, 8 4 links to 5, 6, 7, 8, 9 5 links to 6, 7, 8, 9, 10 6 links to 7, 8, 9, 10 7 links to 8, 9, 10, 1 8 links to 9, 10, 1, 2 9 links to 10, 1, 2, 3 10 links to 1, 2, 3, 4 As you can see, regardless of the amount of websites you are using, the first half of the sites link to exactly half the amount of sites, while the last half links to exactly half the amount of sites minus one. For example: 20 Websites 1 to 10: Each site links to ten other sites 11 to 20: Each site links to nine other sites Remember, when it comes to one-way links, quality still matters. An unrelated one-way link is no better than a reciprocal link.
This is great info. Never thought about it in this direction. I have always trying to put all my websites links on other website. Making them all reciprocal links. I am going to try this. Good Job.
This is simple... but the only problem is.. Google doesnt give much weight or rather no weight to links from same Class C IP's or i have 60 domains all with PR4+ ...
I think the best way is to get other sites to link to yours - either paying them to do so, or offering such good content they are going to want to link - especially offering something interactive that is difficult to replicate for themselves.
Brilliant formula Tyler. It seems every time I find one of your posts, there's more quality content to read and learn about. What blog were you going to put this on? I'll be happy to give you a free one-way link to it when I post about this idea at my SEO blog (see sig). About class C ... how do you tell? And how do you avoid having all the same class C IPs? Do you need to go with different hosts for all your sites??
How deep can you link before a link stops being a one way link? I mean obviously if you do 1 -> 2, then 2 -> 3, then 3 -> 1, they are all one way but are easily detectable... (or 3way links as they call them) so in your case you have 10 way link... I'd say that's a safe assumption... but still how do you gather 0.5 to be the number?
I've never tried that before, but I'd guess that the bigger you went (more sites) then you'd stand a good chance of getting tagged as it being a link network. Search engines can spot patterns in links. Though on a small scale it wouldn't be as noticeable.
I tend to doubt that this sort of scheme would remain undetected, on the long term at least. Perhaps a better way to avoid detection would be to use less than the total of 45 links, maybe 25 or 30. There is also another danger looming, especially with websites that allow feedback from users. I imagine the case of a forum: if a user posts a link that refers to a site in the network of websites, the whole scheme would pretty much fall. Anyway brilliant piece of SEO math.

Tyler, I have found many of your posts in the past to be helpful and insightful... But this! It seems clear to me that PAGE strength (in terms of inbound links) is far more important than something as transient as SITE strength. This equation, while elegant, does not appear at all accurate.
Interesting post. Tell me, is this a general theory then or do you have some data that brought you to this formula? Obviously there are no guarantees with search engines, just curious. I'm interested, too, because I'm developing a webmaster toolkit which includes a linking engine. My goal is to make a very flexible system that can handle custom formulas such as this and monitor progress over time. Progress in this case is hard to nail down to just a few factors, though, considering the number of variables at work here in addition to just where and how many links there are. (IP, relevancy, placement, strength, etc.)
Site 1 links to Sites 2, 3, 4, 5, 6 Site 2 links to Sites 3, 4, 5, 6, 7 Site 3 links to Sites 4, 5, 6, 7, 8 Site 4 links to Sites 5, 6, 7, 8, 9 Site 5 links to Sites 6, 7, 8, 9, 10 Site 6 links to Sites 7, 8, 9, 10 Site 7 links to Sites 8, 9, 10, 1 Site 8 links to Sites 9, 10, 1, 2 Site 9 links to Sites 10, 1, 2, 3 Site 10 links to Sites 1, 2, 3, 4 Total: 45 Links Not exactly true. In this scenario, 3 does not link back to 1. As far as the 0.5, that's just the number it worked out to be I'm actually going to test this out (on a large scale), just to see how it works. I'll let you guys know This is a valid point, but not at all set in stone. I have many sites that rank well with the majority of links pointing to the site, not individual pages. Over the weekend I actually sat down and drew up an experiment, so over the coming months I will put this equation to the test (on a large scale) and see how effective it really is.
