Strategies and Tools to Boost SEO for React Apps
Peek through the essential attributes of SEO and learn about some strategic approaches and tools that will help you to improve SEO for React Apps.
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 in 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
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.
Limited crawling budget
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.
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.
Strategies and Tools to Boost SEO for React Apps
Isomorphic React Apps
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.
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.
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
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.
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.
