1. E-E-A-T
Prioritizes content based on Experience, Expertise, Authoritativeness, and Trustworthiness. Credibility is the foundation of every extraction.
2. Clarity
Prefers pages with a direct answer in the first paragraph. Concise, "inverted pyramid" style writing wins the snippet spot.
3. Freshness
For time-sensitive queries, Google extracts from the most recently updated indexes to ensure real-time accuracy.
4. Consensus
When multiple reputable sites agree on a fact, Google gains the confidence to surface it as a definitive "Exact Answer."

Technical Methodology
Google's automated systems analyze structural data (Schema.org), textual clarity, and domain-level authority. By aligning content with these pillars, creators minimize "time to result" for users, increasing the likelihood of being the primary source of truth in the SERP (Search Engine Results Page).
