如何设置canonical标签

首先需要明确一下什么是 canonical 标签。canonical 标签是告诉搜索引擎该页面的主 URL，防止搜索引擎将同一页面的不同 URL 误认为是不同的内容，从而造成重复内容的问题。以下是设置canonical标签的步骤： 1. 在网页head标签中添加canonical标签。例如： 2. 在 href 属性中填写该页面的主 URL。该 URL 应为该页面的标准或规范 URL，而不应是其他版本的 URL。 3. 尽可能地在每个网页的 head 标签中添加 canonical 标签，以免搜索引擎认为同一页面有多个 URL。 4. 若网站有分页的情况，应在每个分页页面的 canonical 标签中填写主页面的 URL。 5. 如果您使用 CMS（如 WordPress），则可以使用插件或扩展来设置 canonical 标签。以上就是设置canonical标签的步骤。请注意，正确设置canonical标签是优化您的网站和提高搜索引擎排名的重要步骤之一。
