2022年搜索引擎工作原理及SEO新手入门指南
一、搜索引擎三大核心功能 | Three Core Functions of Search Engines
搜索引擎通过爬取(Crawling)、索引(Indexing)和排名(Ranking)三大步骤为用户提供精准信息。Search engines provide accurate information to users through three key steps: Crawling, Indexing, and Ranking.
1. 爬取机制 | Crawling Mechanism
搜索引擎蜘蛛(Spider)会从种子URL出发，抓取网页/PDF/MP3等多种格式内容。Search engine spiders start from seed URLs to crawl various content formats including web pages/PDFs/MP3s.
2. 索引建立 | Index Construction
基于算法、地理环境等多维度参数建立内容分类体系，相关性是核心指标。The indexing system is built based on multiple dimensions including algorithms and geographic factors, with relevance being the core metric.
3. 排名算法 | Ranking Algorithm
根据用户查询关键词，从索引库中匹配最相关结果进行排序展示。The system matches the most relevant results from the index database based on user queries and displays them in ranked order.
二、网站收录检测 | Website Indexing Check
使用site:域名命令可查看收录情况，更精准数据需通过Google Search Console获取。Use site:domain.com command to check indexing status, with more accurate data available in Google Search Console.
三、收录问题排查 | Indexing Troubleshooting
- 新站等待期 | New site waiting period
- 缺乏外链支持 | Lack of backlinks
- 网站结构复杂 | Complex site structure
- 存在屏蔽代码 | Blocking codes present
- 可能被惩罚 | Possible penalties
四、robots.txt的重要性 | Importance of robots.txt
通过robots.txt文件可控制搜索引擎抓取范围，避免重复页面/敏感信息被索引。The robots.txt file controls search engine crawling scope, preventing indexing of duplicate pages/sensitive information.
