Guide to Static Site Generation (SSG) with Next.js

A comprehensive guide to Static Site Generation (SSG) with Next.js, including methods and benefits.

Static Site Generation (SSG) plays a crucial role in modern web development, and Next.js is one of the frameworks that facilitate this process. Unlike Server-Side Rendering (SSR), SSG pre-generates pages, delivering them instantly when needed. This approach offers several benefits in terms of performance, cost, security, and scalability. Here is a guide on how to implement SSG using Next.js and its advantages.

Performance Enhancement

SSG significantly reduces page load times. Since all pages are pre-generated during the build process, they can be served instantly upon user request. This is particularly effective in preventing performance degradation during high traffic periods.

Cost Reduction

Next.js’s SSG method eliminates the need for complex server-side logic, reducing server maintenance costs. The resources required to serve static files are minimal, and cost-effective services like cloud storage can be used to operate even more economically.

Security Improvement

Since no server-side code is executed, SSG reduces security risks. Concerns about server-side vulnerabilities like SQL injection and XSS are eliminated, making the website more secure.


Static files generated by SSG can be easily distributed. Using a Content Delivery Network (CDN), content can be delivered quickly from anywhere in the world, enhancing user experience and website accessibility.

Implementing SSG in Next.js

1. Using getStaticProps

   export async function getStaticProps() {
     const res = await fetch('');
     const data = await res.json();

     return {
       props: {

2. Using getStaticPaths

   export async function getStaticPaths() {
     return {
       paths: [
         { params: { id: '1' } },
         { params: { id: '2' } },
       fallback: false,

3. next export

Generate the static site by building and exporting it to the `out` folder.

   next build
   next export

4. Hosting

Upload the `out` folder to a web server or hosting service that supports static files (e.g., Netlify, Vercel, GitHub Pages) to deploy it.

SEO Optimization

Next.js’s SSG method greatly contributes to SEO performance. Sites composed of static files allow search engines to crawl and index content more quickly. Additionally, fast loading speeds improve user experience and increase the chances of ranking higher on search engine results pages.

Accessibility Improvement

Static sites are generally compatible with various browsers and devices. This enhances accessibility, allowing a broader range of users to easily access and use the site. Additionally, the speed and performance of the website are directly linked to user satisfaction, making SSG important in this aspect as well.

Integrating Various Data Sources

Next.js allows the use of various data sources. External data can be fetched via API calls, or content can be managed using Markdown files. This allows the site to feel dynamic while maintaining its static nature.

Plugins and Extensions in Next.js

Next.js supports various plugins and extensions that help developers easily extend website functionality. Features like SEO optimization, image optimization, internationalization, and improved routing can be added to enhance the overall quality and performance of the website.

Maintenance and Updates

Maintaining a static site is relatively simple. When content or design changes are needed, update the source code and rebuild to deploy. This simplifies the process of applying changes, enabling efficient operation.


Considering these advantages, Next.js’s SSG is a vital tool in modern web development. It offers outstanding performance, security, and SEO benefits even in constrained Node.js environments. Thus, it is highly recommended for developers looking to build fast and reliable websites for businesses or personal projects, minimizing technical constraints while maximizing results.
