Author: Chi Vo - Content Writer According to Statista, React. JS is the second most used framework for frontend developers in 2022, accounting for nearly 43% of the survey’s responses. Therefore, with the popularity of React in Web App development, creating an SEO-friendly React Web App is more essential than ever. However, combining Javascript vs SEO is a complicated task that necessitates a comprehensive understanding of both search engines and open-source frameworks.
In this article, GCT Solution - a leading web app development company, will provide some best practices that make your React Web App more SEO-friendly, thereby gaining more traffics and authority to your web pages.
To create an SEO-friendly web app, developers should understand Google Bot’s working process and the challenges that React Web App faces.
First, Google crawls web pages by using a bot. The bot crawls your website's pages in search of fresh content. By putting the page list in the robots.txt file when building a website, you can pick which pages will be indexed. To prevent bot queries from overwhelming your website, you can also hide or remove some pages.
The second stage performed by the Google bot is indexing. During this procedure, a Google bot evaluates the web page's content to determine its subject topic. The results of this procedure are kept in Google's index, which is a massive database containing information on all web pages. Web page indexing is automated, so it is crucial that all material is structured and formatted in a machine-readable manner.
The third phase consists of serving and ranking procedures. When a user conducts a search, Google searches its index for the most relevant and qualified results
Simple as it sounds, right? Let’s find out what are common SEO issues when it comes to JS pages.
Normally, the crawling and indexing process of HTML pages will occur as follow:
The HTML indexing process does not take up too much time. However, when it comes to Javascript pages, the procedure is way much more time-consuming and complicated.
After these steps are made, the link will be put in the crawling queue and waiting for the indexing and ranking process.
In comparison, the Javascript indexing process is obviously more time-consuming than HTML’s.
As aforementioned, Google bots crawl JavaScript and HTML web pages in completely different ways. A minor bug in the JavaScript code can prevent website crawling.
This is due to the fact that the JavaScript parser does not permit any single error. If the parser and character meet at an unexpected location, parsing of the current script is paused and SyntaxError is evaluated.
Consequently, a simple error or typo can make the entire script useless. If the script contains an error, the content will not be seen by the Google bot, and the page will be indexed as a page without content.
The time required for parsing and loading JavaScript is a bit longer. As JavaScript requires network calls to execute content, the user may be required to wait until it receives the requested information.
The longer users must wait for the page's content, the lower the Google bot will rank the website.
Sitemap is the file that shows the overall information of your website, ranging from site structure to the website’s main content. With clear instructions and mapping, Google Bot can easily crawl your site and decide its position.
