Why Website Speed and SEO Matter
Your website is your most important salesperson — it works 24/7. But if it is slow, broken, or invisible to Google, it is costing you money every single day.
53% of mobile visitors leave a site that takes more than 3 seconds to load. A 1-second delay in page load time reduces conversions by 7%. And Google has confirmed that Core Web Vitals are a ranking factor — slow sites rank lower.
That is why we built this free tool. We want every business owner to understand exactly how their website performs — and what they can do to fix it.

Frequently Asked Questions
What does this website checker test?
Our free website health check analyzes your site across 30+ checks in 4 categories: SEO (title tags, meta descriptions, structured data, Open Graph), Security (HTTPS, mixed content, CSP headers), Accessibility/ADA compliance (ARIA labels, form labels, skip navigation), and Performance (Google Lighthouse scores including FCP, LCP, Speed Index, TBT, CLS, and TTI).
Is this website checker really free?
Yes, 100% free with no signup, no email required, and no limits. We built this tool to help businesses understand how their website performs. If you need help fixing the issues we find, our team at Web Designer Chicago is here to help.
How accurate is this website audit?
Very accurate. Our performance metrics come directly from the Google PageSpeed Insights API, which runs a real Lighthouse audit on your page. This is the same tool Google uses to evaluate websites for ranking. SEO, security, and accessibility checks are performed by analyzing your page HTML against current web standards.
What is a good website health score?
A score of 90-100 is excellent and means your site is well-optimized. 70-89 is good but has room for improvement. 50-69 needs work — you are likely losing potential customers. Below 50 is critical and requires immediate attention. Most small business websites score between 40-65.
What are Core Web Vitals?
Core Web Vitals are Google's metrics for measuring real-world user experience: Largest Contentful Paint (LCP) measures loading speed (should be under 2.5s), First Input Delay / Total Blocking Time (TBT) measures interactivity (should be under 200ms), and Cumulative Layout Shift (CLS) measures visual stability (should be under 0.1). These directly affect your Google search ranking.
How do I improve my website score?
The most impactful improvements are: optimize images (use WebP/AVIF format), minimize JavaScript and CSS, enable browser caching, use a CDN, add proper meta tags and structured data, fix broken links, add HTTPS, and ensure mobile responsiveness. For a complete overhaul, consider migrating to a headless architecture like Next.js which typically scores 90+ on Lighthouse.
Does page speed affect Google rankings?
Yes. Google has confirmed that page speed is a ranking factor, especially on mobile. Sites that fail Core Web Vitals thresholds are penalized in search results. A 1-second delay in page load time can reduce conversions by 7% and page views by 11%.
What is ADA compliance for websites?
ADA (Americans with Disabilities Act) compliance means your website is accessible to people with disabilities. This includes screen reader compatibility, keyboard navigation, proper heading structure, image alt text, sufficient color contrast, and form labels. Non-compliant websites risk lawsuits — over 4,000 ADA website lawsuits were filed in 2025.
