Additionally, Google reported removing or blocking the following:

  • 170+ million reviews that violated policies,
  • 14 million increase in detecting policy-violating videos
  • 2+ million attempts of fraudulent claims on business profiles being thwarted due to enhanced security protocols.

Key Benefits For Local Businesses

Google reports that its new fake review detection algorithm can help local businesses in the following ways:

  • Faster Detection: The new machine learning system detects suspicious review patterns more quickly than previous methods, which can help protect businesses from the harm of fraudulent reviews.
  • Increased Accuracy: The accuracy of identifying fake reviews has improved by 45% compared to 2022, which can give businesses more confidence that their online ratings primarily reflect real customer experiences.
  • Scam Protection: The algorithm identifies individual fake reviews and broader coordinated efforts to post scam reviews, providing businesses with enhanced protection from organized fake review campaigns.

Takeaways For Local Marketers & Business Owners

Google states its continued effort to tackle fake content will benefit users and protect local businesses by better securing their online reputations.

The update could lead to a more level playing field, with reputation becoming a more accurate reflection of service quality and genuine customer satisfaction.

For businesses, the message is to concentrate on delivering exceptional products and services, while Google works to ensure online reputation matches real-world performance.
