.htaccess http ://www. 和 http ://: what is the influence for SEO?

Question

我正在努力提高我的 SEO 排名:我使用 http://www.woorank.com工具我有一个“服务器错误”告诉​​我:

Be sure that http://roulette-chat.fr and http://www.roulette-chat.fr are not running in parallel.

Redirecting requests from a non-preferred hostname is important because search engines consider URLs with and without "www" as two different websites.

Once your preferred domain is set, use a 301 redirect for all traffic to your non-preferred domain.

有人能告诉我如何用 .htaccess 解决这个问题吗？问候

Answer 1

用您的域名替换 example.com。

RewriteEngine On
RewriteCond %{HTTP_HOST} !^example\.com$
RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]
