Why You Should Test Your Page Without JavaScript

Your website might be invisible to users and search engines without you even knowing. 😱 The culprit? Relying too much on JavaScript.

Disabling JS isn’t just a niche developer trick—it’s a crucial quality check. It reveals the true foundation of your website. Before you dismiss it, consider what breaks when the scripts don’t run.

## What You’ll Discover

• Accessibility Gaps ♿ Many assistive technologies, like screen readers, rely on the raw HTML. If your core content or navigation only appears after a script runs, you might be excluding an entire audience. A blank page without JS is an inaccessible page.
• SEO Weaknesses 📈 While Google is great at rendering JavaScript, it’s not instant. Crawlers prioritize the initial HTML payload. If your content, links, and meta tags aren’t in that initial document, you’re making it harder for search engines to index your site effectively and quickly.
• Performance Bottlenecks 🐢 Testing without JS shows you the absolute baseline of your site’s performance. You get to see the user experience on a slow network or a low-powered device before heavy scripts download, parse, and execute. This is your “worst-case” scenario.
• A Single Point of Failure 💪 Networks are unreliable. Ad blockers or firewalls can block scripts. A single error in one script can prevent others from running. If your site becomes a useless white page when JS fails, it lacks resilience. The principle of progressive enhancement—starting with a functional HTML base and enhancing it with CSS and JS—solves this.

What do you see? Can you still read the content and navigate the site? If not, you’ve found your next important task.
