How do international mainstream platforms evaluate the freshness of content in GEO?

The evaluation of content freshness in GEO by major international platforms typically revolves around three core dimensions: publication time, update frequency, and relevance to content timeliness. Platforms such as Google and Bing verify the original publication time through timestamps, assess the dynamic value by combining the content's historical update records (e.g., revision frequency, proportion of new information), and adjust weights by matching the timeliness needs in users' search intent (such as keywords like "latest" or "2024"). Differences in content types affect evaluation criteria: scenarios like news and technological trends require "instant freshness," where platforms prioritize crawling content published within 24-48 hours; while long-term content such as tutorials and guides focus more on "sustained freshness," i.e., regularly supplementing cases, updating data, or analyzing industry trends. It is recommended to update core content at fixed intervals (e.g., monthly), add clear time markers (e.g., "Last updated in X month 2024"), and adjust the relevance of content timeliness in conjunction with industry hotspots to improve the freshness score of content in GEO.
