Abstraction: Google's official guide listing active and retired Search ranking systems
Key points:
- Google published a guide to Google Search ranking systems listing currently active systems including BERT, RankBrain, MUM, Neural matching, PageRank, Helpful content system, and Spam detection systems
- Also lists the Passage ranking system, Product reviews system, Site diversity system, Freshness system, and Local news system as currently active
- Retired systems include Hummingbird, Panda, Penguin, Mobile-friendly ranking, Page speed, and Secure site systems — some retired by being folded into newer systems (e.g., Page speed incorporated into Page experience)
- The document provides brief explanations of each system's purpose
- Distinguishes between systems that are multiple subsystems and those that are single systems
