Google has blacklisted BMW.de after the carmaker violated the search giant’s guidelines by using a technique that could artificially boost its search engine rating, according to a Google engineer.
In a blog, Google software engineer Matt Cutts said that Google had removed BMW’s German site (click here to view site) from its Web index after the site included “doorway pages” that would automatically redirect visitors to a different URL.
Cutts explained that when Google’s crawlers visited a BMW page, it saw blocks of text with repeated key search words such as “neuwagen,” which means “new car” in German. However, when a user visited the listed page they would be automatically redirected to another page with less text and more pictures, which was more attractive than the page the crawler saw, but would have scored lower in Google’s PageRank system.
“This is a violation of our Webmaster quality guidelines, specifically the principle of ‘Don’t deceive your users or present different content to search engines than you display to users,'” said Cutts’ blog.
