SEO (Search Engine Optimization) is crucial for ensuring your website ranks well on search engine results pages (SERPs) and drives organic traffic.

In this blog post, we'll explore how you can optimize your Next.js website for SEO success.

Understanding SEO Basics

Before diving into Next.js-specific SEO techniques, it's important to understand the fundamentals of SEO. This includes optimizing meta tags, using relevant keywords, creating quality content, and ensuring a positive user experience.

Search Systems

Search Systems are what you typically refer to as Search Engines (Google, Bing, DuckDuckGo, etc.). They are massively complex systems that tackle some of the biggest challenges in technology history.

Search Systems have four main responsibilities:

Crawling – the process of going through the Web and parsing the content in all websites. This is a massive task as there are over 350 million domains available.
Indexing – finding places to store all of the data gathered during the crawling stage so it can be accessed.
Rendering – executing any resources on the page such as JavaScript that might enhance the features and enrich content on the site. This process doesn't happen for all pages that are crawled and sometimes it happens before the content is actually indexed. Rendering might happen after indexing if there are no available resources to perform the task at the time.
Ranking – querying data to craft relevant results pages based on user input. This is where the different ranking criteria are applied in Search engines to give users the best answer to fulfill their intent.

What are web crawlers

Imagine web crawlers as robotic librarians for the internet. Their job is to visit websites, just like you would, and discover all the information on them. They follow links from page to page, just like you might click from one article to another.

These crawlers work for search engines like Google. By understanding the content of websites, search engines can then show them in search results when people look for relevant information.

It's important to note that Google (the biggest search engine) isn't the only one with crawlers. Other search engines like Bing and Yandex use similar technology.

Key SEO Factors to Consider in Next.js

SEO Optimization Techniques for Next.js

1. Meta Tags and Title Optimization

Metadata is hidden information about a website that helps search engines and users understand its content. Optimizing meta tags, including title, description, and keywords, is essential for improving visibility and enticing users to click through to your website.

Title: This is the big, bold heading on the card, like the title of a book. It should be clear, concise, and accurately reflect what your website is about. Search engines use the title to understand your content and show it in relevant searches.
Description: This is like a short summary on the back of the library card. It gives users a quick idea of what your website offers and why they should visit. While not directly affecting search ranking according to Google, a good description can significantly increase click-through rates.

import Head from 'next/head';
 
function IndexPage() {
  return (
    <div>
      <Head>
        <title>
          iPhone 15 Pro Max For Sale in Colorado - Big Discounts | Apple
        </title>
        <meta
          name="description"
          content="Check out iPhone 15 Pro and iPhone 15 Pro Max. Visit your local store and for expert advice."
          key="desc"
        />
      </Head>
      <h1>iPhones for Sale</h1>
      <p>insert a list of iPhones for sale.</p>
    </div>
  );
}
 
export default IndexPage;

2. URL Structure and Canonical URLs

URL Structure is an important part of an SEO strategy. While Google doesn't disclose which weight each part of SEO has, great URLs are considered a best practice no matter if they are a big or small ranking factor in the end.

Maintain a clean and descriptive URL structure, and use canonical URLs to avoid duplicate content issues and consolidate link equity.

You might want to follow some principles:

Semantic: It's best to use URLs that are semantic, meaning that they use words instead of IDs or random numbers. Example: /learn/basics/create-nextjs-app is better than /learn/course-1/lesson-1
Patterns that are logical and consistent: URLs should follow some sort of pattern that is consistent among pages. For example, you want to have a folder that groups all product pages, instead of having different paths for each product that you have.
Keyword focused: Google still bases a considerable part of their systems on the keywords a website contains. You might want to use keywords in your URLs to facilitate understanding the purpose of the pages.
Not parameter-based: Using parameters to build your URLs is generally not a good idea. They are not semantic in most cases, and search engines might confuse them and demote their rankings in results.

3. Server-Side Rendering (SSR) for SEO

Next.js’s server-side rendering (SSR) capabilities provide search engines with fully-rendered HTML content, improving SEO visibility. By using the getServerSideProps function, you can fetch data during the server-side rendering process and pass it as props to your pages. This ensures search engines see the complete content of your pages. Here’s an example:

export async function getServerSideProps(context) {
  // Fetch data from an external API
  const res = await fetch("https://api.example.com/data");
  const data = await res.json();
  return {
    props: { data },
  };
}

4. Implementing Open Graph and Twitter Cards

The Open Graph protocol, originally developed by Facebook, standardizes how metadata is used on any given web page. You can provide as little or as much information as you would like, but all of the open graph pieces fit together to create a representation of the site it's attached to.

Other social media companies (like Pinterest, Twitter, LinkedIn, etc), may also use open graph for displaying rich cards when sharing a URL.

While these Open Graph tags have a lot of similarities with SEO related tags, they do not offer any benefit to search engine rankings, but they are still recommended to use as people might share your content on social media or private messaging tools such as WhatsApp or Telegram.

import Head from 'next/head';
 
function IndexPage() {
  return (
    <div>
      <Head>
        <title>Cool Title</title>
        <meta name="description" content="Checkout our cool page" key="desc" />
        <meta property="og:title" content="Social Title for Cool Page" />
        <meta
          property="og:description"
          content="And a social description for our cool page"
        />
        <meta
          property="og:image"
          content="https://example.com/images/cool-page.jpg"
        />
      </Head>
      <h1>Cool Page</h1>
      <p>This is a cool page. It has lots of cool content!</p>
    </div>
  );
}
 
export default IndexPage;

5. Optimizing Images for Search Engines

Optimize image file names, alt text, and dimensions to improve accessibility and ensure images are indexed by search engines.
