搜索引擎工作原理三部曲
通过《SEO新手入门系列2022（二）：SEO 101》的基础介绍，本文将深入解析搜索引擎的三大核心工作机制：抓取（Crawing）、索引（Indexing）和排名（Ranking）。
Three Steps of Search Engine Operation
Building on the foundation from "SEO Beginner Series 2022 (Part 2): SEO 101", this article will delve into the three core mechanisms of search engines: Crawing, Indexing, and Ranking.
1. 抓取阶段（Crawing）
搜索引擎通过"蜘蛛程序"（Spider）从种子URL出发，像织网般持续抓取互联网内容。这些内容形式多样，包括网页、PDF、MP3等，均通过URL定位。
1. Crawing Phase
Search engines use "spider programs" to continuously crawl web content starting from seed URLs. The crawled content comes in various formats including web pages, PDFs, MP3s, all located via URLs.
2. 索引阶段（Indexing）
这是一个涉及算法、地理环境和社会学研究的复杂过程。搜索引擎根据内容相关性建立分类索引，为后续排名提供数据基础。
2. Indexing Phase
This is a complex process involving algorithms, geographical factors and sociological research. Search engines build categorical indexes based on content relevance, providing data foundation for subsequent ranking.
3. 排名阶段（Ranking）
当用户输入查询时，搜索引擎从海量索引中快速检索相关内容，并根据相关性和其他参数进行排序展示。
3. Ranking Phase
When users enter queries, search engines quickly retrieve relevant content from massive indexes and display results sorted by relevance and other parameters.
