One of the main work by Bing Index Quality team is related to web spam detection and filtering. Web Spam is nothing but a webpage whose owner uses black hat SEO techniques in an effort to game Bing’s search algorithms with the goal of gaining undeserved ranking for this page or other pages in the spammer’s network. Bing team tries to find these web spams and removed or reduces their rankings in search results page. Recently, they detailed how they detect web spam on the web. If you are a website owner or a webmaster, you need to read it.
Why is it important to detect web spam?
- Delight users with superior search results quality – spam results are typically inferior quality that push down good results by gaining undeservedly high placement
- Contribute to reduction of malicious content – There is much supporting data (both from our analysis as well as external studies) that shows a high overlap between spam and malware
- Contribute to the betterment of the internet ecosystem – Simply put, if Bing, Google and other search engines are able to eliminate spam from results, it would cut off the traffic, i.e. spammer’s bloodline, to the spam sites, thus putting them out of business and making the entire internet ecosystem cleaner and safer for all
- Improve utilization of our resources – Index space is neither free nor unlimited. Detecting and removing spam websites from the index helps prevent wasting index space and provides more space for good pages
