搜索引擎工作原理详解

How Search Engines Work in Detail

1. 网页抓取(Crawling)
搜索引擎派出爬虫(spider)程序,通过URL链接网络爬取内容。初始会从高质量"种子URL"开始,不断发现新链接进行抓取。

1. Crawling
Search engines deploy spider programs to crawl web content through URLs. Starting from high-quality "seed URLs", they continuously discover new links to crawl.

2. 建立索引(Indexing)
抓取的内容会经过复杂算法处理,考虑相关性、地域性等多维度因素进行分类存储,为后续快速检索奠定基础。

2. Indexing
Crawled content undergoes complex algorithmic processing, considering relevance, geography and other factors for classification and storage, laying the foundation for quick retrieval.

3. 结果排序(Ranking)
当用户搜索时,搜索引擎从索引库快速匹配内容,根据相关性算法进行排序,最相关的结果优先展示。

3. Ranking
When users search, the engine quickly matches content from the index and sorts it by relevance algorithms, displaying the most relevant results first.

如何检查网站是否被收录?

网站未被收录的常见原因:

Common Reasons for Non-Indexing:

专业建议:合理使用robots.txt文件控制爬虫访问,避免不重要页面(如重复内容、联系方式等)被索引,集中权重到核心页面。

Pro Tip: Use robots.txt properly to control crawler access, preventing indexing of unimportant pages (like duplicates, contact info) and focusing weight on core pages.
