什么是死链

我们在打开网址时，有时会出现“访问的页面不存在”的提示，这是死链的一种最直白的表现方式：通过某个链接进来后发现打不开或者是404页面，那么这个链接就叫做死链。

相关词是布局核心，1个例子讲清Title！

Title指的是网页上的标题，是搜索引擎理解和索引网页内容的重要标识之一。在网页布局中，Title通常位于标签内，放在最前面，紧随标签后。Title应该简单明了地描述网页所包含的主题内容，不应过长或过短，一般不得超过60个字符，同时要包含关键词，方便搜索引擎优化。例如，一篇关于打游戏的文章，其Title可以是“如何打好XX游戏？攻略详解-XX游戏专业站”。通过这样的Title描述，搜索引擎可以更快

H标签优化总结

1. 选择合理的标签：将适当的元素用相应标签包裹，使用h1-h6优先将重要元素包裹，然后依次在页面中分级使用。 2. 使用多个H标签：H标签越多，页面结构就越清晰，应当合理地增加H标签个数，让网页更加有条理，同时搜索引擎的抓取也会收益良多。 3. h1标签做好关键词把控：h1标签应当考虑到SEO，给h1标签加上与网站相关度高的关键词，越好吸粉越好。 4. 合理利用H标签：H标签不应用于非

如何处理死链

404错误页面：很多站长会选择做一个404页面，来引导用户去其他页面。但是为死链制作404页面只是为了引导用户去其他内容页面，却没有真正解决死链的问题，因为搜索引擎爬虫并没有放弃抓取死链，依然存在着资源浪费和降权的危险。提交死链：打开百度站长平台，左侧有一个死链提交通道。但千万要注意，robots.txt不要屏蔽这些死链，因为既然要提交给搜索引擎，那么爬虫就会去检查，如果被屏蔽了，爬虫会抓取不到，
