In today's global digital age, website multilingual support has become a basic requirement to reach a wider audience.However, merely providing content in different languages is not enough. We also need to ensure that the search engine can correctly understand the relationships between these different versions, thus guiding users to the content that is most suitable for their language and region.hreflangThe place where the label takes effect.

For sites built with AnQiCMS in multilingual mode, proper configuration is required.hreflangTags are a key step in improving international SEO performance.AnQiCMS as a system specially designed for content operation and multi-site management, its built-in multilingual support and flexible template mechanism provide an efficient and intuitive solution to achieve this goal.

The built-in multilingual capability of AnQiCMS

AnQiCMS from the very beginning of its design has fully considered the requirements for multi-language content management.Its "multi-language support" feature is one of the core highlights, aimed at helping enterprises seamlessly expand into international markets, allowing content to be directly accessible to users of different languages.This means that, whether you are managing multiple language sites for a brand or different language content on the same site, AnQiCMS can provide a unified and efficient management experience.

The system not only supports content switching and display, but also allows developers and operators to fine-tune every detail of the page through its powerful template engine, including those SEO elements that are crucial for search engines such ashreflangLabel.

UnderstandinghreflangLabel's operation principle

hreflangTags are HTML attributes used to inform search engines (such as Google, Bing, etc.) about the different language or regional versions of a page. When you have an English page along with corresponding Chinese, Spanish, or other language versions,hreflangLabels can help search engines understand: These pages are equivalent versions of the same content, just for different language users or regions.

Its main purpose is two:

  1. Avoid issues with duplicate content:If nothreflang, search engines may treat pages with similar content in different languages as duplicate content, which can affect the ranking of the website.
  2. Improved user experience:Ensure that users are directed to the page version most relevant to their language preference or geographic location.

hreflangTags are usually placed in the HTML page<head>The basic syntax structure is as follows:<link rel="alternate" href="[当前页面URL]" hreflang="[语言或语言-地区代码]">

For example, an English page may have a version for Chinese users in mainland China, as well as a version for Chinese users in Taiwan. Then, these three pages all need to be<head>AnQiCMS How to implement

AnQiCMS How to implementhreflangAutomatic generation and application of tags

AnQiCMS is handlinghreflangLabel flexibility and automation capabilities are demonstrated. The system provides a namedlanguagesThe template tag, specifically used to retrieve the list of configured multi-language sites. Combined with this tag, we can generate all language versions of the website in thebase.htmltemplate file.hreflangLabel.

Firstly, you need to configure your multilingual site in the multi-site management of the AnQiCMS backend.usually, each language version can be considered a separate site, or distinguished by specific categories or pages.Configure these sites, and you can call them in the template.

Let's see how to implement this in AnQiCMS templates. In the header of your website template'sbase.htmlfile (usually containing the common header of the page, such as)<head>tags) you can in<head>Label inside add the following code snippet:

{%- languages websites %}
{%- for item in websites %}
<link rel="alternate" href="{{item.Link}}" hreflang="{{item.Language}}">
{%- endfor %}
{%- endLanguages %}

The meaning of this code is:

  1. {%- languages websites %}：This is an AnQiCMS built-in tag that will iterate through all the multilingual sites you configure in the background, and assign the information of each site towebsitesa variable.websitesIs an array object that contains detailed information for each language site.
  2. {%- for item in websites %}：Here begins thewebsitesArray is being looped,itemThe variable represents a specific language site in each loop.
  3. <link rel="alternate" href="{{item.Link}}" hreflang="{{item.Language}}">: This is the core,hreflangpart of tag generation.
    • rel="alternate": Indicates this is an alternative version.
    • href="{{item.Link}}":item.LinkThe output will be dynamic and show the corresponding page URL of the current language site. For example, if the current page is 'About Us' and there are English and Chinese sites available, then the English site's page URL will be displayed.item.LinkIt is the English URL about our page, the Chinese site.item.LinkIt is the Chinese URL about our page.
    • hreflang="{{item.Language}}":item.LanguageIt will dynamically output the language code of the language site (such asen/zh-CN/frautoThese language codes must strictly follow the ISO 639-1 standard (language codes) and the ISO 3166-1 Alpha 2 standard (country codes, optional).

Through this method, regardless of which language version of the page the user accesses, its<head>there will be links to all other language versions ofhreflangLabels, thus clearly informing search engines of the relationships between these pages.

Configure multilingual site content: ensure consistency and discoverability

In order tohreflangThe label achieves its maximum effect, simply adding code in the template is not enough; content-level configuration is equally important:

  1. Create equivalent content:Ensure that there is corresponding content for each language version.This content should be semantically equivalent but in a different language, not completely different content.In AnQiCMS, you can use its 'Document Management', 'Document Classification', and 'Content Model' features to create and manage consistent structure but different language content for different language versions.
  2. Uniform URL structure:Keep URLs simple and logical, which is very beneficial for SEO. AnQiCMS supports the configuration of 'pseudo-static rules' and you can set clear URLs for sites or content in different languages, for exampleexample.com/en/about-usandexample.com/zh/关于我们.
  3. Using the site language package:AnQiCMS's “Global Function Settings” includes the “Default Language Pack” option, which helps unify the language of the backend interface and some system内置 prompts, but more importantly, it helps maintain consistency of the context of different language versions when creating content.
  4. Internal link strategy:Ensure there are reasonable internal links between different language versions, for example, the English version of the product detail page should link to the corresponding Chinese version of the product detail page, which not only helps users switch languages but also strengthens the search engine's understanding of the relationship between pages.

**Practical Tips and Considerations

In the implementationhreflangWhen labeling, there are several **practices that can further optimize your multilingual SEO strategy:

  • Introductionx-default:In addition to specifying a specific language'shreflanglabel, it is recommended to add ahreflang="x-default"Label.This tag is used to indicate which page should be displayed when the user's language or region does not match any defined language version.It usually points to a language selector page, or a default, automatically detectable user language page.languagesOutside the loop, add a line:<link rel="alternate" href="[您的默认或语言选择页URL]" hreflang="x-default">

  • Self-referencehreflang:Every page should include a link back to itselfhreflangAnQiCMS'slanguagesThe tag loop will automatically generate this item, no extra processing is required.

  • Consistency of bidirectional links:All pages that refer to each other must include links to each other.hreflangLabel. For example, if English page A points to Chinese page B, then Chinese page B must also point to English page A. AnQiCMS calls it uniformly.base.html统一调用languagesLabel ensures this bidirectional consistency.

  • Correct language and region codes: item.LanguageThe output language code must be accurate and correct. For versions that are only for languages, useen/frEnglish; for specific regional language versions, useen-US/zh-CN/es-MXEnglish format.

  • Work together with Canonical tags: hreflangandcanonicalTags serve different purposes.hreflangSpecify the language/region alternative version of the page,canonicalSpecify the preferred (authoritative) version of the page to resolve internal duplicate content
