Why do search engines display old titles after the website title is updated?

In website SEO optimization, webmasters often modify website title keywords and expect search results to display custom titles. However, even <title></title>标签、meta keywordsmeta description和结构化数据中的name属性后,搜索结果仍显示旧标题,这令人费解。本文将对此进行解释。

问题:站长修改了网站首页SEO设置,包括<title></title>标签、meta标签和结构化数据,但Google和Bing搜索结果仍显示旧标题。

原因:并非修改无效,而是搜索引擎的缓存和更新机制。搜索引擎爬虫并非实时更新,而是定期抓取和索引网站内容。即使修改了网站代码,搜索引擎可能尚未更新索引。修改后的内容需重新抓取和索引后才能在搜索结果中体现。

解决方法:修改<title></title>标签、meta标签和结构化数据后,需等待搜索引擎重新收录更新页面。此过程可能耗时数小时到数天,甚至更久,取决于搜索引擎更新频率和网站权重。 搜索引擎算法决定何时重新抓取和索引网站。 建议使用网站管理员工具提交网站地图,加快更新速度。
