I'd be happy to help you understand why some shared links on WeChat may have a logo and description, while others do not.
Firstly, let's take a look at the technical aspects of sharing links on WeChat. When you share a link on WeChat, it is actually an HTTP request that sends the URL and other metadata (such as title, description, and thumbnail) to the WeChat servers. The WeChat servers then process this information and generate a preview of the shared content, which includes the logo, title, and description.
Now, let's dive into the reasons why some shared links may not have a logo and description:
1. Lack of metadata: When you share a link on WeChat, it is possible that the website or webpage being linked does not provide the necessary metadata (such as title, description, and thumbnail) for WeChat to generate a preview. In this case, WeChat may only be able to display the URL and a default icon.
2. No Open Graph protocol: The Open Graph protocol is an open standard that allows websites to specify how their content should be displayed when shared on social media platforms like WeChat. If a website does not implement the Open Graph protocol, it may not provide the necessary metadata for WeChat to generate a preview.
3. Customized sharing settings: When you share a link on WeChat, you can choose to customize the sharing settings by selecting which parts of the content to display (such as title, description, and thumbnail). If you choose not to display certain information, it may not be included in the shared link.
4. WeChat's algorithm: WeChat uses an algorithm to determine what information to display when a link is shared. This algorithm takes into account various factors such as the type of content being shared, the user's preferences, and the overall quality of the content. If the algorithm determines that certain information is not relevant or useful for the user, it may not be displayed.
Now, let's take a look at some examples to illustrate these points:
Example1: A link with metadata
Suppose you share a link to a news article on WeChat. The website providing the content has implemented the Open Graph protocol and provides the necessary metadata (such as title, description, and thumbnail) for WeChat to generate a preview. In this case, when you share the link on WeChat, it will display the logo, title, and description of the news article.
Example2: A link without metadata
Suppose you share a link to a personal blog post on WeChat. The website providing the content does not provide any metadata (such as title, description, and thumbnail) for WeChat to generate a preview. In this case, when you share the link on WeChat, it will only display the URL of the blog post.
Example3: A customized sharing setting
Suppose you share a link to a YouTube video on WeChat. You choose to customize the sharing settings by selecting which parts of the content to display (such as title, description, and thumbnail). In this case, when you share the link on WeChat, it will only display the title and thumbnail of the video.
Example4: A link with a customized algorithm
Suppose you share a link to a social media post on WeChat. The algorithm used by WeChat determines that certain information (such as the description) is not relevant or useful for the user, so it does not display it. In this case, when you share the link on WeChat, it will only display the logo and title of the social media post.
In conclusion, the reasons why some shared links on WeChat may have a logo and description while others do not are due to a combination of factors such as lack of metadata, no Open Graph protocol, customized sharing settings, and WeChat's algorithm. By understanding these factors, you can better tailor your link-sharing strategy to ensure that your content is displayed in the most effective way possible on WeChat.
