Pushing Bad Data- Google’s Latest Black Eye

Google stopped counting, or at the least publicly displaying, the quantity of pages it listed in September of 05, after a collegebackyard “measuring contest” with rival Yahoo. That count number topped out round eight billion pages earlier than it was removed from the homepage. information broke these days through various search engine optimizationboards that Google had over the past few weeks, brought any other few billion pages to the index. this could sound like a reason for birthday celebrationhowever this “accomplishment” could now not replicate well at the seek engine that accomplished it. scraping google

What had the seo network buzzing changed into the character of the fresh, new few billion pages. They had been blatant spam– containing Pay-perclick (%ads, scraped contentand they werein lots of casesshowing up nicely in the seekeffects. They driven out far older, extra set up sites in doing so. A Google representative responded via forums to the difficulty via calling it a “awful facts push,” some thing that met with various groans at some point of the search engine optimization community.

How did someone manage to dupe Google into indexing so many pages of junk mail in this sort of quick time framei willprovide a excessive stage evaluation of the mannerbut don’t get too excited.

Our tale starts offevolved deep in the coronary heart of Moldva, sandwiched scenically between Romania and the Ukraine. In among averting local vampire attacks, an enterprising local had a amazing concept and ran with it, presumably far from the vampires… His idea was to exploit how Google handled subdomains, and not only a little bit, but in a massiveway.

The heart of the issue is that presently, Google treats subdomains a good deal the equal manner as it treats full domain names– as precise entities. this means it’ll upload the homepage of a subdomain to the index and return sooner or laterlater to do a “deep move slowly.” Deep crawls are without a doubt the spider following hyperlinks from the area‘s homepage deeper into the website till it reveals the entirety or offers up and comes back later for greater.

briefly, a subdomain is a “1/3degree area.” you’ve got possibly visible them before, they look something like this: subdomain.domain.com. Wikipedia, for instancemakes use of them for languages; the English version is “en.wikipedia.org”, the Dutch version is “nl.wikipedia.org.” Subdomains are one manner to organize massive sitesrather than multiple directories or even separate domains altogether.

Our jap ecu pal were given collectively a few servers, content material scrapers, spambots, percentaccounts, and some all-important, very inspired scripts, and combined them all collectively thusly…
