站点地图注意要点

真实有效

站点地图的主要目的是方便搜索抓取的，如果地图存在死链或坏链，会影响网站在搜索引擎中网站权重的，所以要仔细检查有无错误的链接地址，提交前通过站长工具，检查网站的链接是否有效。

简化

站点地图不要出现重复的链接，要采用标准W3C格式的地图文件，布局要简洁，清晰，如果地图是内容式地图，每页不要超过100内容个链接，采用分页的形式，逐一开来。

更新

建议经常更新站点地图，便于培养搜索爬虫爬行的频率。经常有新的地图内容生成，这样的网站内容能更快的被搜索引擎抓取收录，网站内容也可以早日被搜索引擎检索。

多样性

站点地图不仅仅是给搜索引擎来看的，根本目的也是方便浏览者，所以网站地图最好兼顾搜索引擎的同时也要兼顾浏览者。我们通常为一个网站建三个站点地图。sitemap.html 页面精美，简洁大方，让浏览者方便找到目标页面的同时也心情愉悦。XML 认真研究自己的网站，把重要的页面标注出来，把不需要纳入的页面加上NO FOLLOW 这样更有利于搜索引擎辨别。URLLIST.TXT 或者ROBOTS.TXT 如果方便最好做一下，yahoo等搜索引擎比较认可，谷歌也有这个项目。另外在robots文本里要写好网站地图位置即格式。

robots.txt文件放在哪里?

robots.txt文件通常放在网站的根目录下，即与主页文件（如index.html）同一级目录下。例如，如果网站的域名是www.example.com，那么robots.txt文件的完整路径可能是www.example.com/robots.txt。

nofollow标签的作用有重大变化

2019年9月10日，Google官方博客表示，nofollow属性将不再仅代表拒绝传递权重，而将拓展为三种属性：rel="sponsored"、rel="ugc"、rel="nofollow"。 1. rel=”sponsored” 该属性用于标示被广告赞助的链接，例如广告合作，展示商标，赞助商链接等。它是告诉搜索引擎，链接是被广告商赞助，而非独立推荐。 2. rel=”ugc” 该属性

sitemap提交后，还需要大量的人力进行维护吗？

不需要，您可以根据具体情况进行定期维护。

sitemap提交后，多久能被百度抓取？

通常情况下，sitemap提交后，百度会在1-2天内进行抓取。但具体时间也受到网站规模、更新频率、抓取限制等因素的影响。如果长期未被抓取，可以检查一下sitemap是否存在问题，并通过百度站长平台的工具进行排查。
