两年前，我曾经写过一篇文章《Google和百度收录网站页面的比较》（发布于2006年4月17日《计算机世界》），分析当时情况下百度和Google搜索引擎对于网站的收录比较，两年过去了，这两个搜索引擎的算法都发生了巨大的变化，那时的比较收录规则已经完全不适用于当前了，现在，我就根据今天搜索引擎当前的发展情况，再次比较和分析一下百度和Google这两大搜索引擎在收录网站方面的异同。首页规则搜索引擎的索

百度一直不收录新站的诊断，从这四个方面：1、查询域名历史，确保没被拉黑。如果这个域名之前被人用来做了灰色行业，则可能被百度等搜索引擎拉入黑名单。查看域名历史的查询工具：https://didi.seowhy.com/history.html2、进入百度搜索资源平台，确保抓取诊断正常。对首页、1-2个栏目页面、任选5-10个内页进行抓取诊断。确保能够成功抓取，并返回200。3、检查robots.tx
