Each testing group had different information in the WHOIS record

Different hosting providers and different payment methods. The standardized website layout contained: Three pages per domain (the homepage and the keyword specific content pages) One internal in-link per page (Links in content) One in-link to homepage from third party site Six total outbound links. Two "junk" links to popular website articles to mimic natural linking profile (old Digg articles) One normal link to keyword test page Three modified links (according to given test) to three separate pages optimized for given keyword Links to internal pages only came from internal links The internal links used the anchor text (random English phrase) that was optimized for the given internal page Outbound links (aka "junk" links) used anchor text that was the same as the title tag of the external page being linked to (Old social media articles) Test Group Isolated This graphic represents an ultra simplified version of five test sites.


In the old experiment each of these differe russia email list nt "variable links" would have attempted to sculpt PageRank in a different way. (Variable link 'a' might use nofollow, variable link 'b' might use JavaScript, etc..) Each of the "normal links" would then point to one of five different pages trying to rank for the same term. For testing purposes, I chose phrases that were completely unique to the Internet. These were phrases that had never been written online before.




(For example, "I enjoy spending time with Sam Niccolls". Just kidding Sam... don't hurt me) In theory, the page that corresponded to the most effective PageRank sculpting method would outrank its competition for these isolated phrases. To make us confident in our results we had to compensate for the inherent noisiness of the Internet. To do this, we ran the experiment in parallel eight times. Test Group Full This shows the full scale of the experiment.
