What Is Dynamic Rendering and How It Affects SEO Rank
It’s a tricky balancing act. Not only does your website need to be formatted in a way that makes it easy for search engines to process it, but it needs to perform better and load faster than the competition.
However, the nice thing about technical SEO is it’s one of the ranking factors that you have direct control over.
The answer: Dynamic rendering.
We’ll break down what dynamic rendering is, why it’s important, why it’s beneficial for your website’s SEO health, and how to implement it.
What Happens When Google Visits Your Webpage
Google uses an automated program, known as a bot, to index and catalogue every web page on the Internet.
Google’s stated purpose is to provide the user with the best possible result for a given query. To accomplish this, it seeks to understand what content is on a given web page, and assess its relative importance to other web pages about the same topic.
Google processes HTML in two steps: crawl and index. First, Googlebot crawls the HTML on a page. It reads the text and outgoing links on a page, and parses out the keywords that help it determine what the web page is about. Then, Googlebot indexes the page.
Google, and other search engines, prefer content that’s rendered in static HTML.
How do you make a modern web experience without sacrificing your SEO?
Most developers accomplish this with server-side rendering.
What’s the Difference Between Client-side and Server-side Rendering?
Client-side rendering is cheaper than other alternatives. It also reduces the strain on your servers without adding more work for your developers.
However, it carries the chance of a poor user experience. For example, it adds seconds of page load time to your web pages, which can lead to a high bounce rate.
That’s bad. You need Google to see that content if you want to rank higher than your competitors and to be found by your customers.
So, Why Doesn’t Everyone Just Use Server-Side Rendering?
SSR is expensive, time-consuming, and difficult to execute. You need a competent web development team to put it in place.
This is the case with Angular, which requires the Angular Universal Library to enable server-side rendering. Enabling SSR with Angular requires a lot of moving parts. If just one piece is out of place, it could confuse web crawlers and lead to a drop in your search results.
React, on the other hand, makes use of the Next.JS library to enable server-side rendering. That means your development team has to maintain an additional server at an extra cost.
So how do you make frameworks like React SEO friendly to please your customers and search engines? The solution is dynamic rendering.

Essentially, it’s a hybrid solution that gives the best of both worlds: a simple-to-scan-and-parse version for bots and a more engaging user experience for site visitors.
How Do You Implement Dynamic Rendering?
Implementing dynamic rendering is a three-step process.
First, you install a dynamic renderer (let’s say Prerender), to transform your dynamic content into static HTML.
Second, you choose the user-agents you think should receive static content. In most cases, this includes search engine crawlers like Googlebot and Bingbot. There might be others, such as LinkedInbot, you also wish to include.
If your prerendering service slows down your server or your HTTP requests increase, consider implementing a cache to store content. Next, determine if your user-agents require a desktop or mobile content. You can use dynamic serving to give them the appropriate solution.
Finally, configure your servers to deliver static HTML.
Verifying Your Configuration
Now you need to make sure that dynamic rendering is working properly. Here are a few things to check:
Mobile-Friendly Test: This is a function of Google Search Console’s suite of tools. Google made the switch to mobile-first indexing for all websites in September of 2020. In other words, Google looks at the mobile version of your website before the desktop one. Therefore it’s important your website is optimized for a mobile-first experience.
URL Inspection Tool: You need to make sure your website is properly crawled and indexed. The URL Inspection Tool will do just that.
Fetch as Google: This is what you will use to determine the effectiveness of your dynamic renderer. It allows you to make sure that individual URLs are properly submitted for indexing.
When Should You Use Dynamic Rendering?
So when should you use dynamic rendering?
Dynamic rendering is a good solution if you have a large website with lots of content that changes frequently (e.g. an e-commerce store with revolving inventory). If that’s the case, then your website requires quick and frequent indexing. Dynamic rendering will make sure that all of your pages get indexed and displayed properly in the SERPs.
It’s also beneficial for websites that rely on social media sharing, such as those with embeddable social media walls or widgets.
Is Dynamic Rendering Cloaking?
Cloaking is the practice of serving markedly different content to search engine bots and humans. This is considered a black hat SEO tactic. While the short-term benefits of cloaking may be tempting, the potential risks are not worth it.
Dynamic rendering is not cloaking, as long as it serves the same end content to both crawlers and human users. It’s only cloaking if you serve completely different content to each.
