Vue server-side rendering is a solution that makes web development more efficient, reliable and fast. It enables the Vue framework to preprocess components on the server and output HTML directly before transmitting them to the browser. This means that Vue server-side rendering can improve website performance and optimize SEO, because search engines can use the rendered HTML to better index the content.

This article will introduce a complete guide to Vue server-side rendering and how to optimize SEO.

How Vue server-side rendering works

Vue server-side rendering is actually a combination between client-side rendering and server-side rendering. The server side will use the Node.js extensive ecosystem and convert the Vue components into HTML strings through a packager (such as webpack) and send them to the browser through Node.js. On the browser side, Vue will directly take over these HTML strings and will not re-render the page. Instead, it will directly interact with the JavaScript logic on the browser side and the DOM, making the page performance faster and the interaction smoother.

How to use Vue server-side rendering?

To use Vue server-side rendering, you need to use the Vue CLI to create a new Vue project. When creating your project, you will be asked to select a few options, including whether to use server-side rendering. Choosing to use server-side rendering will result in two projects, one for the server and one for the client.

A server-side rendered Vue application consists of two parts:

1. Server (Express or Koa, etc.)
2. Vue application

Communication between the server and the Vue application occurs through Vue's server-side plugins, which allow you to use Vue's API and functionality on the server side.

How to optimize SEO?

Using Vue server-side rendering can improve SEO results because search engines can directly view the rendered HTML without waiting for JavaScript to execute. Here are some tips for optimizing SEO:

1. Generate static HTML for each URL

Vue server-side rendering allows you to generate static HTML for each page. This means you can pre-generate HTML pages for each URL and serve them to search engines. This often improves SEO rankings because search engines can see the rendered HTML directly.

2. Render important content

To optimize for SEO, you need to ensure that the main content is rendered into the HTML output so that search engines can recognize and index it. This includes title, abstract, keywords, images, description, etc.

3. Optimize Meta tags

Meta tags are tags that describe the content of HTML pages and are very important for SEO. Make sure there is an optimized set of Meta tags in every HTML page. This will help search engines better understand the content of your page and display more information in search results.

4. Optimize images

Search engines can recognize images and add images as keywords to search results. Therefore, it is recommended to optimize images, including file names and alt text, using appropriate HTML tags in HTML pages.

5. Use custom Vue directives

Vue directives are attributes of custom tags that allow you to add some additional HTML attributes when rendering Vue components. You can use custom Vue directives to make search engines better aware of your page content.

Conclusion

Using Vue server-side rendering can improve the performance and SEO effect of web applications. This article has introduced how Vue server-side rendering works, how to use it and how to optimize SEO. By using techniques such as optimized Meta tags, images, and custom Vue directives, you can help search engines better understand the content of your pages and improve SEO results.
