React JS- the most popular web framework for developing engaging web applications is one of the best front-end tech stacks on which Entrepreneurs trust. But, React SEO 2023 has been a point of great concern for them. In this blog post, we will talk about the basics of React SEO-friendly websites. This guide lists the challenges that restrict React from being SEO-friendly. Alongside this, we will also see the best practices that enable your web application to rank better and higher in Google search results.
SEO has become an integral part of any web application over the Internet. It not only commands the overall performance of a product or service in the market but also hampers the profits and effectiveness of any business owner directly or indirectly. Therefore, considering the same factor, when we talk about Search Engine Optimization or SEO, React websites face enormous challenges. One primary reason is that most React JS developers and development companies focus more on client-side rendering, whereas Google focuses on server-side rendering. This creates tremendous challenges for SEO in React. Moving forward with the blog post, let us first understand How Google Bot Crawls Webpages.
Of all online searches and search engines present, Google receives around 90% of its SEO, making it the most popular search engine for SEO-friendly websites. Before delving into how SEO React works, let’s look into Google’s crawling and indexing process.

Points to Remember:
SEO of React-based websites is utterly crucial. Below are a few SEO Challenges that software engineers and developers can address and fix.
A sitemap is a file where all details about your site’s videos, pages, and other forks are provided, along with the relationship between them. As an intelligent search engine, Google reads this file to easily crawl into your site. React does not possess any inbuilt method to create sitemaps. If you use React Router to manage to route, you need to find tools to create a sitemap. Although, this might require some of your efforts.
Below is a few considerations that are linked to setting up excellent SEO practices.

Let us understand how and why optimizing React for SEO is challenging.
ReactJs is a lucrative choice for web development in 2022, but let us check out what challenges do React developers face when developing an SEO-friendly website.
To help reduce the loading time issue, developers have developed a JS-based Single Page Application(SPA). This is a major problem with SEO for React apps and SEO for React websites. They don’t reload the whole content. Instead, they refresh the content. Thus, this technology has been playing a vital role in elevating the performance of websites ever since its introduction.
SPAs load information in a dynamic process. Thus, when the crawler clicks on a certain link, it challenges completing the page load cycle. The metadata cannot refresh. This is a major reason the crawler cannot show SPA, eventually getting indexed in an empty page format. Generally, none of these are good when it comes to ranking. However, this needs a little concern as the developers can easily resolve these issues by generating separate and individual pages for Google bots. But, here arises another challenge again. Creating individual pages gives rise to business expenses besides difficulties in ranking the website in Google’s first-page search results.
As it is known, Single Page Applications have optimized the website performance; there are several issues regarding SEO.
As we have read that several factors lead to React not being SEO friendly. But, now the question arises ‘How to make react website SEO friendly?’ Well! here is the answer to how you can implement React Js SEO approach and make your React web application SEO friendly.
Being one of the leading approaches to making single-page and multiple-page web SEO-friendly apps, prerendering is usually used when crawlers or search bots fail to render Web pages effectively. Pretenders are unique programs that limit requests to the website. If the request is from a crawler, the prerender sends your site a cached static HTML version. If your set sends the request, the page gets loaded normally.
If you wish to build a React Web application, you need to have a precise piece of knowledge between client-side rendering and server-side rendering. Client-side rendering is a Googlebot and a browser that receives empty HTML Files having less or no content.
These best practices will give you answers to how to make your React website SEO-friendly:
You must know, React follows a SPA (Single-Page Application). However, you can utilize the SPA model more optimally if you appropriately describe certain SEO elements and rules in your pages. This guide needs to open pages as individual URLs without the hashtag(#).
(As per Google, it cannot read URLs linked with hash, and hence it may not index any of the URLs generated with React).
Hence, we are creating URLs in a manner that opens in separate pages. We must use React Router hooks in URLs. Below is a sample of the same:
While building the content, we will recommend you not to run a process with setTimeout. In these cases, Googlebot might leave the page and website when it cannot read the content.
Google considers certain pages as separate pages when URLs contain lower or uppercase.
These two URLs will be considered as two separate and individual pages by Google. To avoid such duplication of pages, compose every URL in lowercase.
Ensure giving “a href” to links. Unfortunately, Googlebot cannot read links provided with onclick. Hence, it becomes vital to define links with a Href to make it easier for Googlebot to spot other relevant pages and visit them.
One important component of SEO is Metadata. Thus, it should pop up on the source code even when React is used. Keeping the description and title in the same structure might not be helpful enough in CTR and other scales of SEO.
Here is when React Helmet comes to play. Below is a sample code structure along with metadata:
If the description element cannot function, try filling in the description by receiving 160 characters of the first sample of page content.
Ensure keeping structured data items in the source code along with the metadata. (Organization schema, Product, etc)
For example, below are Raw & Render versions of yolcu360.com. The structured data displays in a protected form in both versions. Ideally, we see no such difference.
When you test the page with the Rich Results test tool, the structured data on your page can be easily viewed by Googlebot.
You can display metadata or content and elements in Google by operating helmet and server-side rendering together. Any deficiency or potential metadata errors can negatively impact each of the metrics present in search results.
All defective pages run a 404 error code. Hence, this is a gentle reminder to set up files like server.js and route.js.
You should specify your on-page images with “img src”. As per a study, although images show up in its tools without any complications, it still cannot index them.
Using anything like a CSS background with React can lead to difficulties in indexing images.
