Is server-side rendering better than client-side rendering for SEO?

Yes, server-side rendering is better than client-side rendering for SEO.

How does SSR help with SEO?

SSR provides HTML content to search engines that are fully-rendered. This makes searching and indexing the website easier. SSR ensures faster page loading of the website and speed is critical in ranking. SSR generates SEO-friendly features such as metadata and appropriate heading hierarchy that enable search engines to understand the context of the content.

Which rendering is best for SEO?

Client-server and server-side rendering are good for SEO as both have advantages and limitations. However, SSR is best for SEO as CSR has many challenges in ranking in search engines. CSR also requires modern browser support for the execution of JavaScript.

Why is server-side better than client-side?

SSR supports dynamic content based on user requests as it can generate HTML dynamically while CSR requires extra measures like pre-rendering to make the dynamic content indexed properly. Server-side rendering ensures that the initial rendering and subsequent rendering on the server and the client are consistent. This reduces any flickering or mismatch risk. However, since CSR is highly dependent on JavaScript it requires proper handling for indexing the content.

Server-Side vs. Client-Side Rendering: Which One is Better for SEO?

Summary: Search engine optimization (SEO) is enhanced by Server-Side Rendering (SSR), which generates and sends entire HTML pages from the server. To load content in the browser, Client-Side Rendering (CSR) uses JavaScript, which can complicate search engine indexing and slow down the initial page load. Because SSR delivers content more quickly and is easier to index, it typically provides greater SEO benefits.

Key takeaways:-

Server-Side Rendering (SSR) improves SEO by providing search engines with fully-rendered HTML, making content easier to index and rank.
Client-Side Rendering (CSR) can cause slower initial page loads and indexing issues because it relies on JavaScript, but it improves interactivity and user experience.
The needs of your website determine whether you should use SSR or CSR: SSR is best for faster loading and SEO, whereas CSR is best for dynamic, interactive sites with frequent content updates.

Web development is fast evolving with modern application architecture. In this, methods to render content play a key role in determining the websites’ performance and user experience. Two well-known website rendering methods include server-side (SSR) and client-side (CSR). Each website has a different set of requirements so understanding the difference between the two types of rendering will help choose the best suitable one.

This blog post will give a better understanding of server-side rendering vs client-side rendering, the way both work, their pros, and cons, and which one can match your business goals.

What Is Server-Side Rendering, And How Does It Work?

Server-side rendering involves generating a webpage on the server and delivering it to the client’s browser. All web pages are created and merged on the server before they are transmitted to the client’s browser. This reduces client-side processing to an extent. Since it is pre-rendered, search engines index the content effectively which improves search speed and ranking. SSR is generally considered the best approach for JavaScript frameworks when creating SEO-friendly websites, particularly when page speed is critical.

Here is how the SSR works-

The user types the URL in the address bar that they want to visit.
The server serves an HTML response which is ready for rendering to the browser.
The browser publishes the page to be viewed and downloads the JavaScript.
The browser completes React which makes the page interactable.

What Is Client-Side Rendering, And How Does It Work?

Client-side rendering is a relatively new method to render websites. It renders a website’s JavaScript in your browser instead of the browser. Here, the server responds with an HTML document that contains JS files. It does not receive the content from the HTML document. Initially, the website upload time is slow but the subsequent page-loads are quick as they depend on a different HTML page on every route. CSR websites do everything on their own as their page is available after the execution of the code. CSR websites create the URL of each page visited by the user dynamically.

The client-side rendered website works in the following manner-

On entering the URL in the address bar by the user, the server receives a data request at the specified URL.
The server delivers static files like HTML and CSS to the client’s browser at the client’s request for the first time.
The client browser will first download HTML content and then JavaScript. The HTML files connect to JavaScript and start the loading by displaying loading symbols defined by the developer. Here, the user is unable to view the website.
Then, content is generated dynamically once the JavaScript is downloaded.
The web content is now viewable to the user.

What Are the Differences Between Client-Side and Server-Side Rendering?

A comparison between server-side rendering and client-side rendering will help in understanding the concepts easily.

Points of comparison	Server-side rendering	Client -side rendering
Purpose	Generates dynamic content based on user data.	Creates a front-end experience that generates images, layouts, and interactive content.
Accessibility	Has access to all files as it offers existing database server connections.	Does not have access to server files as it does not have a web server database connection.
Execution	A web server executes SSR and takes a longer response time. Execution happens on receiving a server request.	Execution takes place in the web browser based on user activity. Locally executed and is quicker.
Security	Higher security as server-side codes are not accessible mostly from the front end.	Lower security as the script is mostly accessible to the client by using a browser inspection tool.

Client-Side vs. Server-Side Rendering: Which is Better for SEO?

Making a comparison of client-side vs server-side rendering requires a thorough understanding of their strengths and shortcomings. This will help to choose the correct option from the two that suit your website and match the business goals.

Server-side rendering ensures fast page loading which is critical in delivering a good user experience. Pre-rendered content in SSR helps in search engine visibility which enhances a website’s visibility and ranking. SSR is ideal for websites with relatively static content that does not change frequently.

This ensures a consistent website experience for the users over time. SSR reduces the load on users’ devices by handling more content on the server and simplifying the interactions. SSR’s pre-rendered content helps in easy caching and reduces the load on servers on subsequent user requests leading to improved performance.

However, SSR cannot render third-party JavaScript due to which reviews or personalized recommendations from outside will not be visible on a fully rendered website on the server. Reduced interactivity and delays in content updates are some of the limitations of the SSR.

Client-side rendering uses JavaScript to render dynamic content that enables an interactive user interface. CSR allows content updates without complete page reloads that enhance user experience. CSR is suitable for websites that update the content frequently. It empowers applications with rich features within single-page or single-page applications that increase user engagement. CSR optimizes server resources as it distributes rendering processes. This is especially beneficial for content that the users update frequently.

Client-side rendering might face challenges related to SEO services and initial load times for websites that contain heavy content. It has issues with scalability under high website traffic without effective utilization of resources.

Client Side vs. Server Side: Does it Matter to Google and Ranking?

JavaScript SEO services help optimize the rendering and indexing of heavily coded websites by search engines like Google. For further optimization in SEO and Google Ranking, understanding client-side vs server-side rendering is equally important. Server-side rendering is the first choice in the context of SEO and Google ranking. SSR generates a whole set of HTML markups that make it easier for search engine crawlers to search and index HTML content. It quickens the search for a website and SSR also enables faster loading that increases the chance of ranking on Google. However, CSR relies mainly on JavaScript to render the content on the client side.

The table below includes a detailed comparison between SSR and CSR of Google ranking and SEO considerations

SEO Factors	Server-side rendering	Client -side rendering
Indexing	Provides HTML content to the search engines. This makes indexing and crawling the website easier.	Needs additional steps such as dynamic rendering to enable the indexing of content by the search engines.
Page load speed	Results in faster page loading	Initially, it results in slower load times as the browser executes JavaScript code to render content. However, subsequent loading can be faster due to optimizations.
Mobile-friendly	Provides HTML content across all devices consistently that ensures a mobile-friendly website. This improves SEO ranking on Google.	Demands careful optimization to make sure mobile rendering is user-friendly.
Dependency on JavaScript	Lesser dependency on JavaScript for content rendering. It ensures search engines can index the content even in the absence of JavaScript.	Highly dependent on JavaScript for content rendering. So, it requires appropriate handling of JavaScript and ensures search engines index the content appropriately.
Dynamic content	Supports the dynamic content as the server generates HTML dynamically based on database and user queries.	Requires additional measures like pre-rendering to ensure appropriate indexing of dynamic content by the search engines.
