As a website operator who is deeply familiar with the operation of AnQiCMS, I know that every page, including error pages, plays an indispensable role in user experience and search engine optimization.An elegantly optimized 404 page can not only effectively retain potential流失 users, but also convey positive signals to search engines, maintaining the overall health of the website.Next, I will elaborate on how to set TDK (Title, Description, Keywords) for error pages (especially 404 pages) in AnQiCMS.

AnQiCMS in English 404 error page TDK setting strategy

In the AnQiCMS system, the 404 error page is not a conventional content publishing page, so its TDK settings are different from those of ordinary articles or product detail pages. AnQiCMS provides special template files for error pages (such aserrors/404.html或扁平化模式下的Englisherrors_404.htmlThis is the entry point for our TDK configuration.

Firstly, we need to clarify the core goal of the 404 page: inform the user that the page does not exist, guide them back to valid content, and minimize negative experiences as much as possible. Based on this, the TDK settings of the 404 page should follow the following principles:

标题（Title）的设置

The Title tag of a 404 page is crucial, as it will display in the browser tab and search engine results (although the 404 page should not be indexed).A good 404 page title should clearly convey the error message and include the website's brand name to enhance recognition and guide users.

In AnQiCMSerrors/404.html模板中，我们可以直接在<head>Label definition inside.Since the 404 page does not have specific article or category content to provide a dynamic title, we usually use static text combined with the site name.

<title>很抱歉，您访问的页面不存在 - {% system with name="SiteName" %}</title>

这里，我们使用了一个用户友好的提示语“很抱歉，您访问的页面不存在”，并通过{% system with name="SiteName" %}The label dynamically retrieves the global name of the website. This way, regardless of how the website name changes, the Title of the 404 page can remain consistent and professional.

Description (Description) settings

Description meta tag provides a brief summary of the page content for search engines and users.For the 404 page, the description should focus on explaining the error, providing solutions, and guiding the next steps to retain the user.Avoid using language that is too technical or confusing.

In AnQiCMSerrors/404.htmlIn the template, Description can be set like this:

<meta name="description" content="您正在寻找的页面可能已被移动、删除或输入了错误的网址。请返回网站首页，或尝试使用站内搜索功能找到您需要的内容。">

This description clearly points out the possible reasons why the page cannot be found, and provides the two most direct solutions of 'return to the homepage' and 'use the site search'.You can also consider adding contact information to further enhance the user experience.

Keywords (Keywords) settings

For the 404 page, the importance of the Keywords meta tag has greatly decreased.Modern search engines rarely, if ever, rely on Keywords tags when determining page relevance.

  • Leave blank:This is the most common practice, as there are not many valuable keywords to fill in.
  • Use very general vocabulary:If you insist on filling it in, it can include some general vocabulary related to errors and the name of the website. For example:
<meta name="keywords" content="404, 页面未找到, 错误, 网站错误, {% system with name="SiteName" %}">

But please remember, this is more due to habit than actual SEO benefits.Focus on optimizing the Title and Description, as well as the content of the 404 page, will bring greater returns.

Example 404 template TDK structure

Considering the above suggestions, a basic AnQiCMS 404 error page header TDK structure may look like this (locatederrors/404.htmlorerrors_404.htmlof<head>area):

<!DOCTYPE html>
<html lang="zh-CN">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>很抱歉，您访问的页面不存在 - {% system with name="SiteName" %}</title>
    <meta name="description" content="您正在寻找的页面可能已被移动、删除或输入了错误的网址。请返回网站首页，或尝试使用站内搜索功能找到您需要的内容。">
    <meta name="keywords" content="404, 页面未找到, 错误, 网站错误, {% system with name="SiteName" %}">
    <!-- 其他CSS样式、JS脚本等 -->
</head>
<body>
    <!-- 404页面内容，例如提示信息、搜索框、返回首页链接等 -->
</body>
</html>

除了TDK，一个优秀的404页面还应包含清晰的错误提示、返回首页的链接（使用English）}]{% system with name="BaseUrl" %}），可能还有一个搜索框，甚至可以推荐一些热门文章或产品，以最大化地挽留用户，这可以通过AnQiCMS的EnglisharchiveList等内容标签实现。通过这些细致的优化，即使是错误页面也能为网站带来正面的价值。

Common Questions and Answers (FAQ)

1. Can I set the TDK for the 404 page directly in the AnQiCMS backend?It is not allowed.The 404 page is a system error page and not a content entity that can be directly edited by the backend (such as articles, categories, or single pages).Therefore, you cannot find a dedicated TDK setting option for the 404 page in the AnQiCMS backend management interface.errors/404.html) to implement.

2. Does the TDK of a 404 page really affect SEO? Will it be indexed by search engines?An optimized 404 page TDK is mainly designed to improve user experience and provide clear page information.For search engines, the standard 404 response code (HTTP status code) will clearly inform search engines that the page does not exist, and is usually not indexed.However, a poorly designed 404 page that does not provide clear TDK may confuse users and cause them to leave quickly, thereby increasing the website's bounce rate.Although the 404 page itself is not indexed, a good user experience indirectly benefits the overall SEO performance of the website.

3. What types of links should I include in the 404 page to help users?To effectively guide users, the 404 page should at least include the following types of links:

  • Home page link:This is the most basic and important navigation.
  • In-site search box:Allow users to directly input keywords to find target content.
  • Links to popular content or recommended articles:Can attract users to explore other parts of the website.
  • Contact us page link:It is very important to provide users with channels to seek help, especially for corporate websites.
  • Sitemap link (optional):For users who want to get a comprehensive understanding of the website structure, providing a Sitemap can help them navigate.
