Google has changed its search algorithm in late 2005-early 2006. I have been monitoring 154 keywords on Google since 1999. Of these, the number one (#1) search result in 128 keywords is now a Wikipedia article. More than a quarter (38 out of 128) of these "articles" are what the Wikipedia calls "stubs" (one or two sentences to be expanded by Wikipedians in the future). Between 7 and 10 of the articles that made it to the much-coveted number one spot are ... empty pages, placeholders, yet to be written!
This is Google's policy now: Wikipedia articles regardless of their length or quality or even mere existence are placed by Google's algorithm high up in the search results. Google even makes a Wikipedia search engine available to Webmasters for their Websites. The relationship between Google and Wikipedia is clearly intimate and mutually-reinforcing.
Google's new algorithm, codenamed Big Daddy, still calculates the popularity of Websites by counting incoming links. An incoming link is a link to a given Website placed on an unrelated page somewhere on the Web. The more numerous such links - the higher the placement in Google's search results pages. To avoid spamming and link farms, Google now rates the quality of "good and bad Internet neighborhoods". Not all incoming links are treated equally. Some Internet properties are shunned. Links from such "bad" Websites actually contribute negatively to the overall score.
In other words: if Website A has 700 incoming links from 700 different Websites and website B has 700 incoming links, all of them from various pages on MySpace, Website B will be ranked (much) higher in the search results. This holds true even when both Websites A and B sport the same PageRank. This holds true even if the bulk of Website A's incoming links come from "good properties" in "good Internet neighborhoods". Incoming links from MySpace trump every other category of incoming links.
An unsettling pattern emerges:
MySpace whose 110 million users are predominantly prepubescent and adolescents now dictates what Websites will occupy the first search results in Google's search results. It is very easy to spam MySpace. It is considered by some experts to be a vast storehouse of link farms masquerading as "social networks".
Google has vested, though unofficial and unannounced and, therefore, undisclosed interests in both Wikipedia and MySpace. Wikipedia visitors end up on various properties whose search technology is Google's and Wikipedia would have shriveled into insignificance had it not been to Google's relentless promotion of its content.
