可信的外贸SEO推广平台：如何解决谷歌SEO中的重复页面问题
最近很多客户朋友都在问：网站里有重复页面，会不利于谷歌SEO么？
Many clients have been asking recently: Will duplicate pages on a website negatively impact Google SEO?
首先我们要清楚什么是重复页面，就是指一个网站中出现相似重复的网站页面内容，判断页面是否重复的标准是谷歌搜索引擎，而不是人。
First, we need to understand what duplicate pages are - they refer to similar or identical page content appearing on a website. The standard for judging whether pages are duplicate is set by Google's search engine, not humans.
谷歌官方虽未明确说重复内容会带来任何惩罚或负面信号，但早已明确不会索引收录重复的内容（没有收录的网站将错失排名机会，更别提流量了）
Although Google hasn't explicitly stated that duplicate content will incur penalties or negative signals, it has clearly stated that it won't index duplicate content (websites that aren't indexed will miss ranking opportunities, let alone traffic).
01 为什么谷歌不喜欢重复的页面？

Cannot be indexed
Search engines can't index because they don't know if your page needs to be indexed.
无法判断
搜索引擎无法判断，究竟是给哪一个页面优先排名。
Cannot determine
Search engines can't decide which page to prioritize in rankings.

301跳转

301 Redirect
If you have 4 different URLs with identical content, choose one standard URL and 301 redirect the remaining 3 to it.
Canonical标签
使用Canonical标签进行标记，告诉搜索引擎虽然存在多个相同页面，但只有特定页面需要参与排名。

Use canonical tags to tell search engines that although multiple identical pages exist, only specific ones should be ranked.
