Improved Google Spam Filter?

Submitted by tomo on February 26, 2011 - 10:08pm

Google, in response to the flood of recent concern about spam/content farms showing up in their results, have just announced a big change in their system of algorithms which calculate page rankings. They had previously published a Chrome plugin that lets you manually block results, and Google says the new algorithm blocks some 84% of the same sites that people were blocking with the plugin. I guess some people were controversially blocking non-spammy sites, rather than guess that Google's algorithm isn't good enough. Or isn't it?

Matt Cutts, the main anti-spam guy at Google, says the new algorithm change affects 11.8% of queries. Since the change is only effective in the US right now and I can browse from both Vietnam and the US, we can compare results and some one in eight queries should be improved.

So I tested "dog shampoo" out of the blue. I have never had a dog because I think they smell.

In Vietnam, high ranking results included drnaturalvet.com which had a low quality page of filler about dog shampoo and dogshampoo.info which is clearly a made-for-adsense site. In the US, the drnaturalvet link is much lower, but dogshampoo.info maintains the same high position. A link to content farm ehow.com is also lower now. And a link to dogshampoo.co.uk, a made-for-adsense site with nothing about dog shampoo at the time of indexing (see cache) is now gone too.

A search for winrar came up with fairly similar results in either country, and both maintained links to spam sites like software.informer.com.

A search for "tightvnc server authentication successful closed connection" punished duplicate content site pinoytech.org slightly but another duplicate/copy site efreedom.com maintained its position in the top 20. Both copy the StackExchange site SuperUser.com.

So it seems that the new algorithm change is an improvement, but I don't think it goes far enough to filter spammy results. While it may be a slight setback for those guys, they are still in the running and will be emboldened to try to rank higher.

There may still be a need for users to crowdsource a database of filtered spam sites until further algorithm improvements.

Note: The Atlantic did a similar test from India on "is botox safe" and "drywall dust" and found their results to be much improved.

About the author

Asian-American expat living in Vietnam over 3 years. I am involved in tech startups and do Drupal consulting. I choose to live in Saigon and Vietnam and I want to see the city and its people reach their true potential.

Where is Saigon?

It's not wrong to wonder where in the world Saigon is.

Saigon is the name of the city now officially known as Ho Chi Minh City. But most people who call Saigon home call their home Saigon and it's mostly tourists who I hear refer to it as Ho Chi Minh City (or Ho Chi Minh Ville for the French).

After the Vietnam/American War ended in 1975, many place names ceased to exist such as Saigon, South Vietnam, and plenty of street names.

Tu Do is now Dong Khoi, Thong Nhat is Le Duan. And Tan Son Nhut Airport is now Tan Son Nhat International Airport. Rue Paul Blanchy has been Hai Ba Trung since the 1950s.

Those who haven't seen Vietnam for decades will be confused not just by the geographical changes but the incredible amount of development and modernization that has since taken place.
