Best Practices
ReactJS is one of the sought-after web frameworks in this era, as this once-niche framework has become very useful for highly interactive platforms. However, despite its capabilities, they do have a notable caveat in that they tend to have trouble being seen in search engines due to a myriad of technical issues.
In this article, we’ll cover the challenges and then the best React SEO Strategies and Best Practices to ensure that your website can be seen by all and attract a lot of visitors.
Before we head on over to the topics that we’ll cover, let’s familiarize ourselves with ReactJS first. So, ReactJS is an open-source JavaScript library utilized for creating user interfaces. Previously, this framework was used for SPAs or single-page applications and is currently utilized in a variety of interactive apps and websites.
To further understand ReactJS, it has key features and concepts consisting of the following:
Component-Based Architecture:
SPAs or websites that use ReactJS as their framework have code fragments that can be reused; these are called “components”. These pieces of code can then be put together, similar to a LEGO block, to form a cohesive single-page application, or in this case, a highly interactive website
Declarative Syntax:
A declarative syntax is a description that is issued by the user on how the interface should appear in a specific state. ReactJS would then search for an efficient way to update your app or website through the document object model (DOM) so that it can match the state described by the syntax.
Virtual DOM:
This version of the DOM is an in-memory version of the real one. In ReactJS, whenever you apply changes to the data present, the framework itself calculates and modifies only the specific areas that need an update, resulting in a faster-loading platform or website.
JSX (JavaScript XML):
JSX is a syntax extension that permits developers to write HTML-like code directly within the React-powered platform, hence JavaScript. The final result of this syntax is a much more comprehensive, readable, and intuitive component structure that’s easy to tweak around when needed.
Unidirectional Data Flow:
All data inside ReactJS apps or websites flows in one direction, and it's from parent to child components. Since the flow happens only in one way, it's easy to understand your app or website’s behavior and easier to debug when necessary.
Before we cover the best React SEO optimization practices you should use. Let’s cover first the “whys” or the factors that affect React apps or platforms to be seen by visitors and potential customers. Knowing the reasons why React-based platforms struggle to be seen should help you form the right approach in promoting them to your target audience.
With that said, here are some of the likely causes why your React JS app, software, or website isn’t gathering much attention:
The first set of issues when running React JS apps or platforms is of the client-side rendering flavor, which comes in three varieties:
Empty HTML Shell
Google or Yahoo tends to crawl into websites regardless if made in React or not. But in React’s case, sometimes it yields an empty HTML shell. Even if the search engine’s crawlers can execute JavaScript, the issue is that the crawlers need to process more resources to parse the website powered by React.
Crawl Limitations
To link up the issues with an Empty HTML Shell, since crawlers are involved, React-powered apps and websites are prone to limiting the site crawler’s reach. Because the crawlers are hampered in their reach, the result is a partially-rendered website, and that is going to penalize you in the search engine rankings.
Indexing is Delayed
In a similar vein to crawl limitations, because ReactJS-powered sites are loaded via JavaScript after the initial page load, search engines might take a while to discover and index content. Thus, slow-loading sites are further penalized in the rankings.
The second set of reasons why React-powered apps or software tend to suffer in SEO rankings is tied to performance issues, such as the following:
React-powered apps or websites tend to use big bundles of JavaScript. All of these bundles? They require downloading, parsing, and executing before the page can be interacted with by the user. Going through the three processes will cause a negative user experience through slow loading.
To add to the issue with the JavaScript bundle usage, poor loading speeds on a webpage are a big no-no in Google’s SEO ranking, as that search engine values fast-loading sites. This problem becomes more prevalent if your React-powered site utilizes dynamic content where the shifting and changing can influence loading speed.
Now we’ve arrived at the heart of the matter: the best React SEO optimization practices you should consider. Applying these practices should increase your React-built site or platform’s chances of ranking higher in search engine results. Here are some of them listed below:
The first proven React SEO optimization practice that you should apply is to improve your rendering strategy, and it can be done through the following:
Server-Side Rendering or SSR
This rendering option is your best choice as the server generates the HTML content before it reaches any browser being used. The SSR method of rendering also heightens the likelihood that web crawlers will scan your site or platform, making it more visible in SEO rankings.
For instance, SSR rendering is superior when being loaded for the first time. Research shows that 60% of users on slow 3G networks prefer websites with SSR rendering. (DIVA Portal)
Static Site Generation or SSG:
This rendering is ideal for content-oriented platforms such as blogs or sites that feature documented content. This approach pre-renders the HTML at build time, resulting in lightning-fast loading speeds, making your React-powered site easy to crawl through by web crawlers.
A performance comparison shows that SSGs take 20-50 or even 80ms for the time to first byte. Also, SSG is faster than CSR by 1.5 to 3 seconds, for context - SSG content takes half a second or a whole second for First Contentful Paint, whereas CSR takes 2-4 seconds. SSG delivers fast loading speeds consistently, whereas CSR tends to lag as blank pages are more prevalent on it.
Dynamic Rendering:
The last option that’s available for you is Dynamic Rendering. The best way to describe this rendering method is that the bots get the static version, whereas the users will see the dynamic client-side variant. That way, your site still gets indexed on search engines.
A word of caution: Do not utilize CSR or Client-Side Rendering on your React platform, especially on the critical pages. Sole reliance on CSR might result in slow loading times and limited crawler reach, as stated earlier.
Optimizing your URL’s structure is considered one of the best React SEO optimization practices that you can apply to your site or platform. Generally speaking, what you’d want to do is to avoid long strings of random characters. Instead, you should settle for using keywords related to the topic of the page since this can enhance the visibility of your React-powered app or website.
Meta tags are considered essential when enhancing the visibility of your React app or website. These “fragments” of code tip away the content inside your website to search engines, helping said search engines to properly index it for better visibility.
The meta tags that you should focus on are the title tag, meta descriptions, and meta keywords to ensure visibility. Title tags need to be concise, whereas meta descriptions should be brief but informative, and the keywords must be relevant to the title and meta descriptions.
React Routers are a handy tool to have when you own a React app or website. This tool allows you to build single-page platforms or websites more easily with React; for example is a simple React-based website with a front page, a contact page, and an information area.
React Routers also present you with the correct pages whenever someone types in the URL or enters one of your website’s links. The router ensures that the correct content found in the URL or the link is going to be presented to your visitors at a fast speed, ensuring a positive user experience. In addition to that, Routers also update the URL, thus it can be shared by visitors to reach more potential visitors or be bookmarked by previous visitors.
The last React SEO optimization practice that we’ll cover is that you’ll need to provide quality content inside your React platform or website. Make the content engaging and interactive, and give it clear headings and easy-to-read text so that viewers will stick around. Augment the content further with the use of choice and relevant keywords to ensure that it will be visible on the search engines.
By creating quality content on your React app or website, it's assured that your guests will keep coming back for more, hence making your site more visible to potential visitors.
Creating engaging content on your React website ensures visibility and justifies Google’s need to crawl your website. Make sure that your content is fresh and relevant for the best outcomes.
ReactJS is a potent JavaScript library that’s used to create very interactive UI interfaces that give way to very intuitive apps or websites. However, platforms powered by React do face some caveats, such as rendering issues, loading speed, and routing problems, which can affect their SEO rankings. Fortunately, using the right practices, which we’ve covered here, should ensure that your React-powered site or app is visible to the masses.
