What Is JavaScript SEO?
JavaScript SEO is considered a part of technical SEO. The goal of JavaScript SEO is to help websites that contain JavaScript rank higher in search engine results. To make that happen, though, understanding how search engines like Google view JavaScript are absolutely necessary.
JavaScript affects the page load time, the metadata, rendered content and even links. With JavaScript SEO, webpages that use JavaScript are optimised so that they can be crawled and indexed by search engines.
It is thus imperative to take advantage of JavaScript SEO services to rise to the top of search engine result pages.
Is JavaScript Good For SEO?
It depends entirely on how much the script is used on a website. Using JavaScript makes the maintenance of the website easy and scalability also increases. However, JavaScript is incredibly complex, too, and that might cause the search engines to have difficulty crawling and indexing the page. Problems begin when JavaScript is not firmly embedded in the document.
Fortunately, though, search engines like Google and Bing have made changes to better crawl and index JavaScript-embedded websites, so things are changing fast.
It’s important to note that JavaScript can be beneficial to your website if implemented correctly, but JavaScript SEO services can prove to be helpful to make certain sites can properly crawl every page on your site.
How To Improve your Site’s JavaScript SEO
The primary goal of JavaScript SEO services should be to improve the crawling and indexing of every webpage. If the search engine can crawl the website better, the other regular analysis will become much more efficient.
JavaScript SEO can be improved in the following ways:
- Every page should be assigned a separate URL. This will help the crawlers to familiarise themselves with the content.
- The essential scripts should always be the first HTML response for better crawling. The first response includes the meta title, description and data stored in the <head> section.
- Page rendering should be avoided. The render-blocking scripts should be identified and deleted. These render-blocking JavaScripts can be identified using tools like PageSpeed Insights.
- It is also possible to improve JavaScript SEO through pagination, which means instead of creating a large page, several smaller pages can be created so that search engines can crawl them more quickly.
- The Tabbed content needs to be there in the initial HTML response.
How Does Google Process Pages with JavaScript?
If the URL is on Google, it is considered to be in the crawl queue. If you have turned the ‘Noindex’ on then Google will not consider the URL.
Once Google approaches the URL,
- The process begins when the server receives a ‘GET’ request from the crawler.
- The server then lists the header and content of the file. These are saved for further processing.
- Like users, Google does not navigate from one page to another. While processing, it opens a page and further checks its links and resources from where other links are built. These are the links that are also added to the queue. One needs to make sure that Google understands these links. The external and internal links should be with the required <a> tag and href attribute. This is a bit of what it looks like:
- Now comes the caching part. CSS, HTML pages, JavaScript or any other file that Google downloads, will get cached. Here the duplicate contents are discarded or receive low priority ratings.
- From here, every page will go to the renderer and Google renders each page to see the user perception of the webpage. But before entering the render queue, the ‘Noindex’ pages are skipped. This means pages having the ‘Noindex’ tag are not sent to the renderer.
- Google processes the JavaScript or any change made to the DOM in the renderer.
- Finally what the user sees is the indexed version of the page.
The Advantages And Disadvantages Of JavaScript
Before implementing JavaScript on a website, it is important to consider the advantages and disadvantages of this script.
Advantages Of JavaScript
- Applications and websites using JavaScript have high scalability, and as the script runs within the client’s browser, its speed is high and shows better performance.
- JavaScript supports the creation of rich interfaces which, in turn, adds up to the user experience.
- JavaScript comes with a functionality that can be extended easily. The developers can utilise this by adding snippets of JavaScript code.
- Another major benefit of JavaScript is that it can be added to any webpage and application as it supports languages like PHP.
- JavaScript is considered an easy language to understand when compared to other known languages like C++ and others.
- All major modern browsers support JavaScript usage which can help to develop different useful features on different devices.
- JavaScript has an easy and simple syntax that can be easily understood.
Disadvantages Of JavaScript
- Since JavaScript runs completely within the client’s browser, it sometimes becomes more open to the malicious network.
- JavaScript does run the same on all browsers. It is seen differently on each browser. The script needs to be checked on all major browsers to make sure it is interpreted correctly everywhere.
- An error in the JavaScript code can cause the rendering to stop. For the code to run correctly, it must be correct.
