Google tweaks algorithm to kick parked domains out of its index
Thursday, December 1st, 2011
Algorithm change designed to push parked domains out of Google.com index.
Google released an update on new changes made to its algorithm today, and one of them is bad news for anyone who still manages to get their parked domain names in the search index.
New â€œparked domainâ€ classifier: This is a new algorithm for automatically detecting parked domains. Parked domains are placeholder sites that are seldom useful and often filled with ads. They typically donâ€™t have valuable content for our users, so in most cases we prefer not to show them.
It used to be that many parking pages got indexed and this delivered a lot of extra traffic to domain owners beyond just type-in traffic and old links. Google has gotten smarter about this in recent years, and it looks like this latest move may be the nail in the coffin.
Although Google hasn’t disclosed how it determines that a page is parked, it’s not that hard to do. It could even do this based on a combination of page structure and nameservers.
Update: As you’ll see if you try it, if you type in an actual parked domain name to Google it will still show it. I suspect they have just heavily demoted them.
