搜索引擎爬虫工作原理详解
How Search Engine Crawlers Work
1. 爬虫抓取阶段 (Crawling)
外贸网站上线后，搜索引擎的爬虫会通过链接发现并访问您的网站。由于互联网每天新增数百万页面，爬虫会为每个网站分配特定的抓取"预算"，达到配额后便会离开。
After launching a foreign trade website, search engine crawlers discover and visit your site through links. With millions of new pages daily, crawlers allocate a specific "budget" to each site and leave after reaching the quota.
专业建议：完成网站建设后，建议立即向Google Search Console提交XML网站地图(Sitemap)，这能显著加快收录速度。
Pro Tip: Submit your XML Sitemap to Google Search Console immediately after website completion to significantly speed up indexing.
2. 页面收录阶段 (Indexing)
被抓取的页面将进入搜索引擎的索引库，这是获得展示机会的第一步。您可以通过以下方式检查收录情况：
Crawled pages enter search engine indexes - the first step to visibility. Check indexing status with these methods:
- 单页面检查：Google搜索"url:完整页面网址"
- Single page: Search "url:full-page-URL" in Google
- 全站检查：搜索"site:您的域名"查看收录总量
- Full site: Search "site:yourdomain.com" for total indexed pages
3. 排名排序阶段 (Ranking)
收录≠好排名！页面质量、内容相关性、网站权威性等200+因素共同决定最终排名位置。
Indexing ≠ good rankings! Over 200 factors including content quality, relevance, and domain authority determine final positions.
