Why Is JavaScript Crawling So Important?


There are tons of websites using JS and it’s easy to understand why this happens. Using JavaScript in designing and building websites is very popular as it makes it possible to create interactive and dynamic content. Visual animations, navigation, displaying dynamic content to users based on specific behaviors are just a few of the things that can be done with JavaScript.


Yet, analyzing a JavaScript website is not always a walk in the park. It requires a lot of resources and in-depth analyses. Luckily, you don’t need to worry about this anymore as you can run complete Site Audits within cognitiveSEO, on all types of websites. 


Here are just some of the advantages of enabling JavaScript crawling when running a Site Audit: 


You’ll get a more accurate analysis and you’ll have better issues identification.


Many sites use JavaScript generated content, be it completely or partially. Even if your site has only a couple of elements generated with JS, it is highly important to get those sections analyzed as well. It’s always the small pieces that make the bigger picture. 


You can find out how crawlable your pages are with and without JavaScript rendering enabled.


JavaScript analysis is the closest thing you get to what your users actually see within their browsers. You can run an SEO audit, with and without JS enabled and see the differences for yourself.

You can analyze a wider range of websites.


So, let’s say that you want a really cool site template, with a dandy interface, so you choose to create your site using Wix, for instance. That’s awesome! The downside is that in most of the instances you’ll hardly find possibilities of completely analyzing all the technical and SEO issues your site might have.  Yet, the JavaScript crawling gets things done for you, allowing you to analyze sites built with different platforms and programming languages. 


What Is JavaScript and How Does it Work?


JavaScript is one of the most popular programming languages to develop websites. It uses frameworks to create interactive web pages by controlling the behavior of different elements on the page.


Initially, JS frameworks were implemented client-side (front-end) only in browsers, but now the code is embedded in other host software, such as server-side (back-end) in web servers and databases, which will save you from a lot of trouble and pain. The problems started when JavaScript implementation relied only on client-side rendering.


If JavaScript frameworks have server-side rendering, you’ve already solved the problem before it even arises. To better understand exactly why problems appear and how you can avoid them, it is important to have some basic knowledge of how search engines work. For that, we need to establish the phases of the information retrieval process: crawling, indexing, and ranking.



How JavaScript Affects SEO


If you want to find out more about the impact of JavaScript on SEO, you need to know that we wrote a more exhaustive piece of content on JavaScript and SEO.


JavaScript means more loading time speed and faster server load (code functions run immediately instead of waiting for the server to answer), easier implementation, richer interfaces and higher versatility (can be used in a huge variety of applications). But JavaScript SEO brings some problems along the way. Lots of webmasters fail to optimize the content that uses JavaScript code. And this is (most likely) because they don’t have a complete site audit overview. 


Everybody started to doubt whether search engines, like 靠谱的买球平台, are able to crawl JavaScript. And that was the wrong question to ask. The better question to ask is can search engines parse and understand the content rendered by Javascript? In other words, can 靠谱的买球平台 rank your website if it’s made in JavaScript? The truth is that more and more websites are relying on JavaScript, so search engines have improved their page rendering functionality.

Even if not completely maybe, it’s important to know that 靠谱的买球平台 is able to crawl and index the rendered version of pages as well as the HTML version.

  • Does 靠谱的买球平台 crawl JavaScript? ” The answer is more and more lately.
  • Does 靠谱的买球平台 index JavaScript? ” The answer is yes.
  • Should I use JavaScript? ” The answer is it depends on your needs.


A JS website is indexed and ranked. We’ve learned things the hard way until now. We know that making it easier for 靠谱的买球平台 to understand the generated content is the best approach. To help 靠谱的买球平台 rank content that uses JavaScript, you need tools and plugins to make it SEO friendly. And you need a comprehensive SEO analysis to make sure your site is performing as well as it can. 


It’s not all sunshine and roses, we know. You need to know that JavaScript uses up crawl budget as 靠谱的买球平台 requires more resources to render, crawl and index JS websites, adding a layer of complexity to the process. Moreover, JavaScript can be hard to combine with good SEO.
