网站设置301重定向怎么操作？301设置需要注意的事项

1. 打开网站的.htaccess文件，添加以下代码： ``` Redirect 301 /old-page.html http://www.yourwebsite.com/new-page.html ``` 2. 在301重定向前，确保新页面已经正常运行，并且地址没有变更。 3. 如果有多个旧页面需要重定向，可以逐个添加301重定向代码。 4. 重定向的目标地址必须是正确的URL地址，否则会导致错误的跳转。 5. 如果需要撤销301重定向，可以删除.htaccess文件中相应的代码，或修改为新的目标地址。 6. 301重定向是一种搜索引擎优化的技术，但也要注意不要过度使用，避免被搜索引擎视为作弊行为。
