In AnQiCMS custom static rule, what is the difference between `{id}` and `{filename}` variables, and when should they be used?

As an experienced website operator proficient in AnQiCMS, I know that URL structure is crucial for the SEO performance and user experience of the website. The powerful pseudo-static function of AnQiCMS allows us to flexibly customize website links, among which{id}and{filename}Are two core variables, each representing different meanings and usage scenarios. Understanding their differences and making appropriate choices is a key step in building an efficient website.

Optimize URL structure:{id}with{filename}Deep consideration

In the custom pseudo-static rules of AnQiCMS,{id}and{filename}Is used to dynamically generate URL paths. These variables play a key role in the URL construction of documents, categories, single pages, and tags.Their selection is not arbitrary, but requires a comprehensive judgment based on the website's operational goals, SEO strategy, and user habits.

{id}Characteristics and applicable scenarios of variables

{id}A variable in AnQiCMS represents the unique numeric identifier of content, which is usually the primary key ID in the database. When we choose to use in pseudo-static rules{id}for examplearchive==/{module}-{id}.htmlThe generated URL will be/article-123.htmlor/product-456.htmllinks that are purely numeric.

{id}A notable feature is itsStabilityandUniqueness.Each content item has a fixed, unique ID, which makes the URL structure very concise, error-free, and highly consistent in internal data association.Even if the title or alias of the content changes, the ID remains the same, so the URL will not change, which helps to avoid dead links.

However,{id}The disadvantages are also obvious: itLacks semantics. Users cannot intuitively obtain specific information from the URL, which may not be a **choice for user experience and SEO friendliness.Search engines can also recognize numeric IDs during crawling and understanding pages, but URLs with keywords that have semantic meaning are usually more favored.

Therefore,{id}Variables are usually used in the following scenarios:

• Internal system links: When URLs are mainly used for internal system jumps or as API interface paths, stability takes precedence over semantics.
• Content volume is extremely large or the title is prone to change: For websites with frequent content updates and frequently changing titles, using{id}Can minimize the SEO risk and management costs brought about by URL changes.
• Pursue extreme simplicity.If the website design style tends to be minimalist and you do not want the URL to be too long or contain too much information,{id}it is a viable option.

{filename}Characteristics and applicable scenarios of variables

{filename}the variable represents the content of theCustom URL Alias. In AnQiCMS, this alias is usually automatically generated from the title of the content in pinyin or English, and can also be manually entered and adjusted by operators to ensure semanticization and uniqueness.For example, configure in pseudo-static rulespage==/{filename}.htmlThen the "About Us" page may generate/about-us.htmlURL. Documents, categories, single pages, and tags all support setting through the "Custom URL" field{filename}.

{filename}The highlight of itssemanticizedandSEO-friendliness. Keywords in the URL can help search engines better understand the content of the page, thereby potentially improving keyword rankings.At the same time, for users, a semantically meaningful URL is more readable and memorable, which helps to improve the user experience.

But{filename}Also brings some management challenges:

• Maintaining uniqueness: Ensure each{filename}Uniqueness within the entire site, AnQiCMS will automatically handle duplicate situations (such as adding random numbers), but**the practice is manually intervened to make it more meaningful.
• Risk of changeIf the title of the content or manually set{filename}The change may cause the URL to change as well, which may lead to the failure of the original link. It needs to be properly handled through a 301 redirect, otherwise it may affect SEO.

{filename}Variables are more suitable for the following situations:

• Pursue SEO advantagesFor articles, product detail pages, or important categories and tag pages, use keywords containing{filename}Can provide more contextual information for search engines, which helps improve natural search rankings.
• Enhancing user experience: A clear and readable URL allows users to have a preliminary understanding of the page content, enhancing trust and navigation experience.
• Brand and content consistency: The URL should be consistent with the title content, strengthening the brand image and content theme.
• The scale of the website is moderate, and management is controllable.For websites with controllable content volume and dedicated operation personnel maintaining URL strategies,{filename}they can maximize their value.

There is no absolute **answer** when making a choice, but it needs to be matched according to the specific content type and operational strategy:

• Document detail page (article, product): It is usually strongly recommended to use{filename}For example:/news/seo-optimization-guide.htmlor/products/anqicms-enterprise-edition.html. This maximizes SEO benefits and provides users with a more friendly link. If the title is too long or contains special characters, it will generate{filename}Not ideal, should be manually optimized.

• Tag List Page: Similarly, using{filename}You can create a URL like/tags/seo-tools.htmlwhich helps to aggregate content related to the theme and improve the SEO value of the tab.
