How to make your React App
SEO-friendly?
Today, architecting an impeccable and highly performant app/website isn’t
enough to ensure success — you need to make sure that your content appears in
the searches of your target audience as well. And, to meet this requirement, SEO is
essential. Search engine optimization, commonly known as SEO, plays a crucial
role in defining the success of an application or a website as it determines the
amount of organic traffic received. SEO refers to the practice of regulating when,
where, and how an app/website will be displayed in the search engine rankings.

SEO is more important for web apps as compared to a website. This is because web
apps usually contain a lesser number of public pages and each of those pages need
to be exposed to the fullest. Besides, web apps are likely to possess complex UIs on
account of which search engine crawlers may trip and may exclude the app’s
content from their indexes. And, SEO is hassle-prone, if a front-end technology
like React is being used for web development. Thankfully, such challenges can be
resolved with the use of productive strategies, judicious tweaks, and effective tools
for SEO.
This post discusses one of the most sought-after queries of entrepreneurs — SEO
strategies for a React app. React is one of the most popular picks for web app
development and is known to fare poorly in terms of SEO. Therefore, this write-up
guides you through the common SEO challenges encountered by a React app, the
best practices for addressing those roadblocks, and the crucial tools that expedite a
React app SEO.
Importance of SEO
How does a search engine function?
When a user types search keywords on the search box of a browser, the search
engine decides the order in which the web pages are to be displayed. The search
engine employs algorithms for examining the data stored for each webpage. Based
on this data, the algorithms decide which of the web pages’ content is most

relevant to the keywords typed by the user. The pages that are considered to be the
most user-friendly by the ranking algorithms are displayed amongst the top ten.
Here are the key steps!
· Crawling: Crawlers such as Google bots look for new and updated web pages.
This process is conducted by either following links from known sites or by crawling
web host-managed web pages and sites.
· Indexing: The new pages identified are examined by Google for understanding
their contents displayed through texts, images, or videos. The content displayed
via text — meaningful titles, meta descriptions, etc. — is understood best by
Google.
· Ranking: Then, Google provides the list of pages ranked as per the quality of
content and the level of relevance to user searches — most to least relevant.
Role of SEO
It’s highly desirable for a web page to appear in the top ten of the search results to
get viewed by users looking for similar content. The role of SEO is to convince the
search engine algorithms that a specific webpage is the closest match for the
content a user is looking for. Hence, web developers need to make the website/web
app SEO-friendly by incorporating certain code modifications, tweaks, and add-
ons. You must also pay attention to SEO prerequisites like powerful keywords, title

description, heading tags on pages, alt tags on images, canonical tags, and
OpenGraph information.
SEO Challenges encountered by React Applications
SPA Usage
The usage of React-based SPA (Single Page Apps) is preferred for web apps and
websites as it reduces the loading time considerably. SPAs refresh the content
when updating add-ons/changes; instead of the traditional practice of reloading
the entire page. This approach improves the page’s performance and
responsiveness, but poses SEO challenges as given below:
SPAs are likely to encounter indexing woes. A single-page app can provide the
content only after the page has been entirely loaded and, if the loading is
incomplete while a bot is crawling the page, an empty page will be viewed by the
bot. As a result, a major portion of the webpage will not be indexed leading to a
lower search ranking.
JavaScript usage: An SPA uses JavaScript for loading content dynamically into the
various web page modules. There’s a high possibility that bots might miss running
JavaScript pages.
Limited Crawling Budget

Crawling budget refers to the maximum amount of pages on a particular website
that can be processed by search engine crawlers within a given time. The time
devoted to each script is usually five seconds. But, the loading, parsing, and
execution of the script of most JavaScript webpages take more than five seconds
for loading. As a result, the Google bot runs out of its crawling budget for your site
and has to leave it before the indexing is complete.
The Inability of creating built-in Sitemaps
Google bots need to assess sitemaps — files containing crucial information about a
web page, video, etc. — for comprehending a web page for being able to crawl it
correctly. But, React is incapable of creating sitemaps within the given framework.
Meta Tags
For obtaining higher search engine ranks, a webpage must have unique titles, and
descriptions for every page; if not all pages will end up with the same Google
listing. With React is unable to change the tags.
Less likely to crawl JavaScript pages
Earlier, Google used to crawl only HTML pages, but now Google claims to run
JavaScript pages as well. But some bottlenecks persist and Google may or may not
load JS pages. The likelihood of JS pages being crawled depends on several factors

like the usage of obscure engines, the manner in which JavaScript is polyfilled or
transpiled, and so on.
Strategies and Tools to Boost SEO for React Apps
React App SEO Strategies
Isomorphic React Apps
Developing an isomorphic JS technology-based website/web app in React is a
viable solution to boost SEO. This technology auto-detects whether the client-side
has disabled the JS page or not and if Javascript is turned off, Isomorphic JS

renders the code on the server-side and then sends the webpage content to the
client. This way, all the essential content and other prerequisites including
metadata and HTML/CSS tags, are available to the crawling bots at the time of
page loading.
When JS is enabled, the first page gets rendered on the server. This allows the
browser to receive HTML, CSS, and JavaScript files. Thereafter, JS starts to run
and the remaining content gets loaded dynamically.
Prerendering
Prerendering is one of the most prominent approaches that is implemented for
improving the SEO-friendliness of single-page apps as well as multi-page web
apps. This approach is leveraged whenever search engine bots or crawlers are
unable to effectively render pages. Prerenders are distinct programs that restrict
the number of requests made to the website. When a crawler sends a request, the
prerenderer sends the webpage/website a cached static version of HTML. And, if
those set of web pages sends the request, the page is loaded normally.
These programs are effortless to implement, support the most recent web
novelties, and effectively execute various types of latest JS, transferring them into
static HTML. However, such services come with a price, take too long to load in
case of large files, and are less effective for pages that modify data at frequent
intervals.

Server-side rendering
Client-side rendering is not an SEO-friendly option because bots either cannot
detect any content or receive minimal content leading to improper indexing. But, if
you employ server-side rendering, the browsers/bots receive the HTML files
containing the entire content and hence the page is indexed properly; leading to
higher search engine ranks.
For designing an SPA that is going to render on the server-side, React
developers need to add an extra layer of Next.js while crafting the web app.
URL case and ‘Href’ Usage
When the URL of a web page contains the upper as well as the lower case, Google
considers them as separate pages, leading to duplication of pages. So, it is
advisable to create all URLs using the lower case only.
Google bots are unable to read “onclick” links, and so it is recommended to define
web page links using a “href”. This makes it easier for bots to locate your page and
visit it.
React App SEO Tools
React Helmet

This is a library that enables developers to set the HTML metadata in the header of
a component. With this tool, one can easily update the meta tags on the client-side
as well as the server-side.
React Helmet supports every valid head tag including meta, title, script, NoScript,
style, link, and base; server-side rendering; and every attribute for title tags, body,
and HTML. Moreover, it enables callback from tracking the DOM alterations. The
nested components override the duplicate modifications in the head and these
duplicate head modifications are preserved when they are specified under the
same component.
This tool not only makes your web app SEO and social media-friendly, but also
facilitates modifying the title, metadata, and language of the page. Combine
server-side rendering with React Helmet for best results.
React Snap
This tool is responsible for pre-rendering a web app into static HTML and
employs Headless Chrome for crawling all links that are available right from the
root. Moreover, React Snap involves a zero-configuration approach — you need
not worry about its functioning or configuration techniques. Furthermore, it
employs a real browser behind the scenes to avoid any issues regarding
unsupported HTML features such as Blobs, WebGL, etc., and is not dependent on
React.

React Router v4
This is a component for creating routes between the various pages/components
and makes it possible to develop a website having an SEO-friendly structure.
