How to improve your JavaScript to be SEO friendly

In Digital Marketing, the connection between the inherent aspects of the market with the use of technology and web development has emerged more than ever lately. Today, JavaScript and SEO are parts of the same conversation topic.

For this reason, in this article, we will cover everything from basic concepts to how to improve your positioning through the best practices of this programming language on websites and blogs.

First of all, it is important to understand that JavaScript and SEO are disciplines that have complications and complexities france phone number data individually and that, usually, departments work them separately in their strategies.

However, whoever wants to become a professional qualified to respond to the needs of the industry must master both fields, so we decided to make this post.

What are the most important concepts of JavaScript and SEO?

The JavaScript programming language is one how to speed ​​up slow charging of the most used in the world — some of the best websites we have ever visited were built using it. But what are the fundamental concepts that unite both disciplines?

To properly understand JavaScript and SEO, the first thing to be clarified is that when it comes to positioning, search engines are not able to fully understand, assimilate, or process JavaScript source code.

However, there is a way to prepare a website so that when Google starts the crawling and indexing process, it can decipher it.

Indeed, the most popular search engine in the western world showed concern for this issue, and that’s how AJAX came about, which is basically to improve  a content updater.

AJAX allows applications to communicate with servers and indicates what’s new without having to crawl or refresh the entire page.

Now, how does it work?

First, the robot that processes JavaScript works in three steps:

• Tracking
• Processing
• Indexing

When identifying a URL that contains this email leads database language, the first task is to verify that the user has allowed the identification.

To do so, the robots.txt file is read, and, if it has been authorized, Google begins processing. Finally, after analyzing the HTML, it starts to be indexed.

All of this happens because JavaScript is not executed for servers, but for browsers. Therefore, search engines must assume the position of a browser to be able to capture or read the content.

What role does JavaScript play in web pages concerning SEO?

To answer that question, we must go back to AJAX, the acronym for Asynchronous JavaScript and XML.

This technique was developed for mobile devices and websites. Its function? Initially, make changes to the content without having to load all the HTML.

So, does it affect SEO? The answer is yes! AJAX “usually” — using the words of Google spokespersons — can render and index dynamic content, but it is not always like that. This ends up directly influencing search engine positioning.

Now, at this point, it is important to understand the limitations that Google has to process JavaScript. For example, most users use browsers to improve  like Chrome and Mozilla, among others.

Besides that, the Google robot does not use the latest version of these browsers, but Chrome 41 does the processing, a fact that can drastically affect tracking.

For this, there are Google’s own tools, such as the optimization test or the URL inspection tool of Search Console, in which you can view the features that are shown and the exceptions you can make to JavaScript or DOM (Document Object Model).

What are the SEO problems that happen with the misuse of JavaScript?

Although JavaScript helps to show the user dynamic rendering websites, full of interesting graphics, pleasant interfaces, among other things, several mistakes — that negatively influences SEO and, consequently, the potential of the site — can be easily made.

Here we show the most common mistakes that you can make.

1. Neglect HTML

If the most important information on the site is within the JavaScript code, the crawler may have very little information to do the proper processing when it comes to indexing for the first time.

2. Misused links

Any SEO professional knows the importance that internal links have for positioning.

This is because search engines and their crawlers recognize the connection between one page and another. This increases the user’s residence time.

3. Accidentally prevent Google from indexing your JavaScript

This may be the most common of the three problems. As we already mentioned, Google cannot completely render JavaScript.

Because of that, many websites may be making the mistake of including “do not index” tags in HTML.

That is why when Google scans a website and reads HTML, it may find that tag and pass straight.

That prevents the Google robot from returning to run the JavaScript that is inside the source code, preventing it from showing correctly.

JavaScript remains an attractive and important aspect for web development, whether it is for brands, companies, e-commerces, or other purposes.

To prevent Googlebot and other to improve  crawlers from going straight, it is important to
