To avoid the issue of Google not being able to find JavaScript content, a few webmasters use a process called “Cloaking” which makes the JS content available to users but hides it from browsers. However, this method is considered a violation of Google’s Webmaster Guidelines and may result in penalties. Instead, work on identifying the underlying issues and making the JS content accessible to search engines.
Use Relevant HTTP Status Codes
Google's crawlers use HTTP status azerbaijan phone number library codes to identify problems when crawling a page . Therefore, you should use a meaningful status code to tell bots that a page should not be crawled or indexed. For example, you can use a 301 HTTP status to tell bots that a page has moved to a new URL and allow Google to update its index accordingly.
Fix Duplicate Content
When JavaScript is used for websites, there can be different URLs for the same content. When you find such pages, make sure to choose the original/preferred URL that you want indexed and set canonical tags to avoid confusing search engines.
Fix Laggy Content and Images
Site speed is crucial for SEO. Lazy loading is a type of user experience best practice that delays the loading of non-critical or non-visible content, thus reducing initial page load time. But in addition to making pages load faster, you also need to make sure your content is accessible to search engine crawlers. These crawlers will not be able to execute your JavaScript, negatively impacting your SEO.
What’s more, image searches are also a source of additional organic traffic, so if you have images that load slowly, search engines won’t select them.
JavaScript is placed between <head></head> codes and the codes are executed from top to bottom. If your JavaScript script has a lot of codes, your website will take longer to load. But by postponing some unimportant steps, you can prevent JS from parsing them and increase your site speed.
