Just as technical and content SEO are important, JavaScript SEO is also of great importance. A “Page has broken JavaScript error” is a significant issue in the realm of Technical SEO. This error occurs when pages link to JavaScript file URLs that return 4xx or 5xx HTTP status codes, which are essentially indicators of broken links. The importance of addressing this error for SEO purposes cannot be overstated.
Why is Page has Broken JavaScript Error Important for SEO?
Firstly, browsers and search engines are unable to render broken JavaScript files. This directly impacts the user experience on your website, as any content that is supposed to be created or manipulated by these JavaScript files won’t be displayed correctly. More importantly, from an SEO perspective, if JavaScript files are intended to generate content, this content will not be indexed by search engines. This means that potentially valuable content, which could have contributed to your site’s SEO, remains invisible to search engine algorithms.
Furthermore, search engines, like Google, prioritize user experience as a key factor in ranking websites. A site with broken JavaScript links can reason to a bad experience for users, and can negatively affect your site’s search engine rankings. Ensuring that all JavaScript files are functioning correctly is therefore crucial not only for the immediate user experience but also for maintaining and improving your website’s visibility and ranking in search engine results.
How to Fix Page has Broken JavaScript Error?
Fixing a “Page has broken JavaScript error” involves several steps. The first step is to identify the problematic JavaScript files. You can do this by checking the “Linked JavaScripts” column for the HTTP status code of the file. The most common HTTP status codes you might encounter include:
- 404 (Not Found): This status code suggests that the file might have been moved or deleted, but the link to it was not updated. To resolve this, you can restore the JavaScript file at the old URL, update the link on the page to point to a relevant file, or remove the link altogether if the JavaScript file is no longer needed.
- 403 (Forbidden): This indicates that access to the JavaScript files was blocked, possibly due to server or firewall configurations. In this case, whitelisting the IP addresses of your crawlers and running a new crawl can be a solution.
- 429 (Too Many Requests): This may suggest that the crawling speed set in your crawl settings is too high for the web server. Adjusting the crawl speed in the settings and re-running the crawl can address this issue.
- 5xx (Server Error): These codes indicate server issues. You should consult with your developer or hosting provider to resolve these, as they may involve server misconfigurations, overloads, or general performance issues.
