搜索引擎工作原理详解 | Detailed Explanation of Search Engine Working Principles
通过《SEO新手入门系列2022（二）》我们初步了解了SEO和搜索引擎的基本概念。本文将深入解析搜索引擎的三大核心工作流程：
Following "SEO Beginner's Guide 2022 (Part 2)", we've learned the basic concepts of SEO and search engines. This article will delve into the three core processes of search engines:
1. 网页抓取（Crawling） | 1. Web Crawling
搜索引擎通过蜘蛛程序（spiders）沿着URL链接不断抓取网络内容，包括网页、PDF、MP3等各种格式的文件。初始抓取从高质量"种子URL"开始，通过链接不断扩展抓取范围。
Search engines use spider programs to continuously crawl web content through URL links, including various formats like web pages, PDFs, MP3s, etc. The initial crawl starts from high-quality "seed URLs" and expands through links.
2. 建立索引（Indexing） | 2. Indexing
这是一个复杂的计算机处理过程，涉及算法、地理环境、社会学等多方面因素。搜索引擎根据内容相关性进行分类存储，为后续快速检索和排名提供数据基础。
This is a complex computer processing involving algorithms, geographical environments, sociology and other factors. Search engines classify and store content based on relevance, providing data foundation for subsequent retrieval and ranking.
3. 排名展示（Ranking） | 3. Ranking
当用户输入查询时，搜索引擎从庞大的索引库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。排名越靠前的内容，与用户查询的相关性越高。
When users enter queries, search engines quickly retrieve relevant content from the huge index library and display results sorted by relevance and other parameters. Higher-ranked content has stronger relevance to user queries.
如何检查网站收录情况？ | How to Check Website Indexing Status?
使用site:yourdomain.com命令可以查看网站在搜索引擎中的收录情况。如果未被收录，可能原因包括：
Use site:yourdomain.com command to check website indexing status in search engines. Possible reasons for not being indexed include:
- 新网站尚未被收录 | New website not yet indexed
- 缺乏外部链接 | Lack of external links
- 网站结构过于复杂 | Overly complex website structure
- 存在阻止爬虫的代码 | Code blocking crawlers (noindex, nofollow)
