- Penguin: An algorithm that targets websites that use spammy or manipulative tactics to try to improve their rankings.
- Hummingbird: An algorithm that focuses on understanding the meaning behind a search query rather than just matching keywords.
- RankBrain: A machine learning algorithm that helps Google better understand and interpret ambiguous or complex search queries.
- BERT: Another machine learning algorithm that helps Google understand the context and meaning of words in a search query.
- Mobile-friendly update: An algorithm that prioritizes mobile-friendly websites in search results, particularly on mobile devices.
- E-A-T (Expertise, Authority, Trustworthiness): An algorithm that assesses the expertise, authority, and trustworthiness of a website and its content, particularly for topics that could impact a user’s health, safety, or financial wellbeing.
