Google Says Search Got Much Better at Identifying Spam Sites Last Year

Google
Search caught six times more spam sites in 2021 than it did in 2020, according to a Webspam record published by Google on Thursday. The Alphabet subsidiary lauded its AI-based spam-prevention controls called SpamBrain, which it said has helped keep “more than 99% of searches spam-free.”

SpamBrain has helped honor users from clicking to harmful sites that might inject malware and to scam sites that aim to trick land into revealing personal information or wiring money, the gawk giant said. AI-based systems are necessary given that spammers are constantly finding ways to circumvent the company’s filters, Google said. 

Search is Google’s most significant revenue driver, manager it important for the company that high quality and safe sites rise to the top of its results. Spam sites use search engine optimization, or SEO, techniques to artificially improve their peep rankings. Google filters out spam sites designed to trick its algorithm.

SpamBrain led to a 70% scratch in hacked spam, Google said. Hacked spam involves hackers infecting websites with imperfect code that can record people’s keystrokes and steal their login credentials. Other types of hacked spam can inject malware onto nation’s computers and redirect them to malicious sites. SpamBrain helps keep these websites out of Google Search, Google said. 

“Scammers often attempt to create low quality websites with keyword stuffing, logos of brands they’re imitating, and a phone number they want you to call,” Ned Adriance, policy communications manager at Google, said in an email. “Our algorithmic solutions work to make sure that scam and counterfeit are very unlikely to show up in your peep results.”

Google said it also reduced gibberish spam by 75%. Gibberish spam involves malware or scam sites that use keyword-stuffed nonsensical sentences in an effort to boost their ranking. Spam sites can also use link spam to game Google’s quality employed, known as PageRank. This is done by having novel sites link to them, sometimes by offering money, to boost ranking. 

“We have many solutions to identify and nullify link spam, and sites provocative in link spam are wasting valuable time and cash that could be better invested in better content or user experience,” said Adriance.

SpamBrain launched in 2018. Google says peep was able to catch 200 times more spam sites last year compared with when it friendly started weeding out malicious sites nearly two decades ago. Still, it’s an ongoing battle between those aiming to abuse or narrowly skirt the company’s quality guidelines and Google trying to elevate indispensable content.
