Google Explains How to Identify Indexing Issues Linked to JavaScript
Understanding JavaScript’s Role in SEO Issues
Google’s Martin Splitt recently discussed how website indexing issues are often misdiagnosed, clarifying that JavaScript is rarely the main reason for SEO setbacks. In a SearchNorwich video, Splitt explained that SEOs often misidentify JavaScript as the culprit when, in reality, the root cause usually lies elsewhere.
Misusing JavaScript: The Real Problem in SEO
Splitt emphasized that JavaScript is not frequently the root cause of indexing problems with Google. Martin Splitt highlighted the following key points:
- JavaScript is not to blame: Most SEO issues attributed to JavaScript are caused by other factors, such as poor website structure or incorrect implementation.
- Confirmation bias leads to misdiagnosis: Many SEOs jump to conclusions, assuming JavaScript is the root cause without thoroughly investigating.
- Out of hundreds of reported cases, only one involved a JavaScript bug: This emphasizes that most issues are unrelated to JavaScript.
- The problem is often in the execution: Incorrect implementation or blocked resources, not the JavaScript code itself, is usually the culprit.
Debugging Crawling & Rendering Issues
Splitt offered actionable advice to help webmasters diagnose indexing issues potentially linked to JavaScript. He recommended using tools like:
- Google Search Console URL Inspection Tool: To check how Googlebot renders your pages.
- Google Rich Results Test: To understand what content Google indexes from your site.
- Chrome Dev Tools: To view JavaScript console messages and network activity.
These tools help you quickly spot and fix crawling issues. Splitt explained that rendering is when Google downloads all webpage resources, like fonts and JavaScript, to create a page that looks like what users see. Debugging can show if parts of the page are missing or not loading fully.
Splitt also said that JavaScript errors don’t always mean a problem with the code. For example, if Robots.txt blocks an API, the page won’t load right. This isn’t a JavaScript issue but a setup problem. He advised checking these basics to avoid wasting time.
Looking Ahead
The insights from Google’s Martin Splitt highlight a critical shift in how SEOs approach indexing issues. Moving forward, a deeper understanding of debugging techniques and correct implementation of JavaScript will be essential for website owners to enhance visibility and optimize performance in search engines.
