Some people may misunderstand this as simply layering javascript over a document made essentially in HTML format, but Javascript powered websites have a little more complicated model than that. In these websites, the website’s primary content is injected into a DOM (Document Object Model) via javascript. In contrast, the peripheral or non-primary content can still be coded via HTML.

Can we know if a website is built using Javascript?

Yes, we can, and there are many easy and quick methods to determine whether a particular website is built using Javascript. Technology profiler tools like Built with and Wappalyzer have been developed to help choose the platform using a website. Alternatively, one can also check for Javascript code using “view source” or “Inspect Element” in the browser.

JavaScript SEO for key content

JavaScript provides the web designer with the ability to construct and structure an interactive website rapidly. Modern apps are designed using JS frameworks like Angular, React and Vue. When these apps viewed on the browser upgrade the quality, we can see the link text and images. Using DOM, you can inject the core content in the single page application for the website without actually writing it in the code. That is, you can create a code without the main content. When using this method, the app becomes dependent on JavaScript to load key visible content.

You may face some issues while injecting the key content via JavaScript. If the content is visible to users but not to search engine bots, it may cause serious complications. This issue may bounce visibility, and search engines could fail to spot your website, giving an advantage to your competitors.

JavaScript SEO  for internal Links

Now that we have understood how Javascript can affect the core of the critical content on a website, it will be easier to know how it affects the internal links embedded on a webpage. In general, the crawlability of a link defines how easy it will be for a search engine to discover that link. Search engines like, Google, yahoo and Bing crawl links to identify and find new webpages.

Many Search engines (like google) recommend using HTML anchor tags and href attributes to link pages to improve the crawl ability of the internal links as Javascript can deteriorate the link crawl ability and visibility. It is recommended that developers use static HTML elements only to embed links and not rely on JS handlers or other technologies.

If the links are uncrawlable and not optimized for the search engines, it can be harmful to the web page’s visibility via the search engine. The internal links leading to the webpage may get missed by the Search Engines, and this may even lead to your webpage being undiscoverable by the search engine.

  • Decrease the use of JavaScript
  • Inline JavaScript
  • Serving JavaScript with compact payloads

The speed of a website plays an imperative role in website ranking. Slow pace websites can create potential SEO issues and proffer terrible experience to the web engine and traffic. Google itself delays JavaScript loading, and web designers must ensure to deliver efficient code that can help safeguard their rankings.

JavaScript SEO for metadata

In today’s techno world is necessary to note the SPA’s which use a router package like React, Router or Vue- router and implement some additional ways to manage things in a more organized manner when the audience comes on the website to navigate. These meta tags are handled with the help of the Node.js package, for instance, Vue-meta or React-meta-tags.

So, for better Search Engine Optimizations, one uses packages like React Helmet and ensures the quality of unique metadata while browsing.
