Since the launch of Blekko, we have had a clear mission; and that is to eliminate spam from web search. With thousands of slashtags created by our users to help reduce spam, we are making quick and significant progress in achieving our set goals.
In the past, our efforts to clean-up search have included our partnership with the Stack Overflow community, and our public banning of the top 20 sites most users marked as spam at Blekko.
Today, we are taking the next giant step forward with the launch of Blekko’s new AdSpam algorithm. This new technology will dramatically change search. It’s the first search algorithm ever created to find spam rather than rank results. The algorithm is specifically designed to recognize pages which are spam and eliminate them before they ever appear in search results.
Blekko has used the AdSpam technology to eliminate more that 1.1 million domains that support multi-millions of pages.
So what is exactly is AdSpam? In short, it is a machine-learning algorithm that examines pages for a specific spam signals — the presence of multiple display ad positions on a single page and thin to zero content. Unlike algorithms used by other search engines, AdSpam is being used in conjunction with human curation to detect to continue the War on Spam.
So in a time where spam-free search is becoming increasingly important, you can be sure that Blekko’s new AdSpam technology will scan every new page on the Web before it gets added to Blekko search results. We believe the way to better search results is by using an algorithm that was created to kill spam, not just crawl it.
