Analysis

Google's clear preference for older sites, particularly in the single industry above (although circumstantial evidence and other, less documented testing shows this effect to be quite broad), could be due to several factors. I will attempt to document the possible reasons and then attempt to disprove them through the evidence gathered from the SERPs.

* Older Sites are Preferable Due to Age of Links

This possibility cannot be dismissed and would be exceptionally difficult to disprove. It would account for all of the factors of an age bonus, but would have to be overwhelmingly strong in the algorithm and have a negligible effect after a certain period - i.e. a link that is 24 months old is just as good as a link that is 48 months old. Several searches above suggest that the effect is almost plateau-like, or similiar to a challenge system. Once a certain level age. links ,or some other unknown factor is reached, the site is given a 'pass' that allows it to compete in the SERPs with other old sites. This is definitely one explanation for the 'sandbox effect'.

* Older Sites are Preferable Because they Inherently have More Links

Unfortunately, this is a naive assumption. While many of the sites listed above do have a great number of links, not only due to age but also to quality of content and link building programs, they are clearly surpassed by many newer sites in both quality and quantity of links. Sites with higher PR and higher numbers of links are rnaking well behind these sites in Google's SERPs. Older sites have nothing 'inherent' to them except their age.

* Older Sites Rank Better Because they Offer Better Content

This myth is exceptionally simple to reject by looking at GG's search results for non-conforming loans or business real estate financing. Although I have not completed an independent analysis of the quality of each result, most of the searches above offer ten sites with excellent information in the top 100-200 results, but only 1-2 are in the top 10. Logic also tells us that older sites will often contain outdated information, and dozens of the sites above have seen few updates over the past 2-3 years, further degrading their content.

* Older Sites Rank Better Because There are More of Them

This argument presumes that the ratio of sites from 2002 and before compared to sites from 2003-2004 is higher in the top 10 because there simply are more sites from this time period. However, the ratios are vastly unbalanced, with only 4 sites in the above 100 results that were started after 2002. Site registration and promotion, on the other hand, has been progressing at a breakneck level over the past 2 years, fueled by a recovery from the post-dot-com-crash era.

Jeff, one day you’ll understand that it’s harder to be kind than clever.
