AnQiCMS'urlizeFilter: automatically addrel="nofollow"the behind-the-scenes work of the property

To put it directly, according to the document provided by AnQiCMS, itsurlizefilter will indeed automatically identify and make the URLs and email addresses in the text clickable<a>When labeling, it will automatically addrel="nofollow"Property. This design consideration reflects the efforts of AnQiCMS in SEO friendliness, aiming to help us better manage the external link weight of the website.

urlizeThe working principle of the filter is relatively direct: When we use it in a template to process a piece of text, it intelligently scans the text content, identifies strings that match the URL or email address format, and then converts them into standard HTML hyperlinks. For example, a piece of ordinary text containshttps://en.anqicms.comAfterurlizeAfter filtering, the URL in this text will become<a href="https://en.anqicms.com" rel="nofollow">https://en.anqicms.com</a>. It can also handle formats likewww.anqicms.comor[email protected]this common format.

Automatically addedrel="nofollow"Properties, for us content operators, have important SEO significance.nofollowThe tag tells the search engine that we do not want to pass 'link voting' or 'PageRank' to the target pages of these links.This is particularly useful when dealing with user-generated content (such as comments, messages), advertising links, or any external links we do not wish to endorse.It can effectively prevent the link weight of a website from being unnecessarily scattered, avoiding SEO risks that may arise from linking to low-quality or irrelevant content.

urlizeActual application and注意事项 of filters

In AnQiCMS templates,urlizeFilters are usually used in combination with other filters, the most common being|safefilters. Due tourlizeThe filter generates HTML tags, to ensure that these tags are correctly parsed by the browser and not displayed as plain text, we need to use|safeThe filter informs the template engine that the output content is safe HTML and does not require escaping.

Here is a simple application example:

{# 假设content变量中包含一段含有URL的文本 #}
<p>{{ content|urlize|safe }}</p>

In addition, AnQiCMS also providesurlizetruncA filter that performsurlizesimilar functions but adds an extra feature: it can specify the display length of the generated link text. If the URL is too long,urlizetruncIt is very useful to truncate a part of the URL and add an ellipsis at the end while maintaining the validity of the link, which is very practical when there are requirements for the length of the link in page layout or visual. For example:

{# 将URL截取显示为前15个字符 #}
<p>{{ content|urlizetrunc:15|safe }}</p>

Regardless of usingurlizeOrurlizetruncthey will all follow the automatic additionrel="nofollow"rule, which provides a layer of default SEO protection for us when dynamically generating links.
