Why Website Speed Matters
Google has confirmed page speed is a ranking factor, and Core Web Vitals — Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP) — are built directly into how Google evaluates every site, regardless of platform. Beyond rankings, speed affects real business outcomes: sites that load in under 2.5 seconds see meaningfully lower bounce rates, and every extra second of load time costs conversions.
This applies whether your site runs on WordPress, Shopify, a static site generator, or fully custom code — the underlying performance principles (server response time, image size, JavaScript execution, caching) are the same everywhere, even if the fixes look different platform to platform.
How to Use This Website Speed Test
- Enter any website’s full URL in the box above (e.g. https://yoursite.com) — your own site, a client’s, or a competitor’s
- Choose Mobile or Desktop — test both, since Google evaluates them separately and mobile is usually slower
- Click Analyze and wait 15–30 seconds while a real audit runs
- Review your score, Core Web Vitals, and the ranked list of opportunities
- Work through the highest-impact fixes first — they’re sorted by potential time savings
Understanding Your Results
- Largest Contentful Paint (LCP) — how long it takes your main content to load. Under 2.5 seconds is good.
- Cumulative Layout Shift (CLS) — how much your page visually jumps around while loading. Under 0.1 is good.
- Total Blocking Time (TBT) — how long your page is unresponsive to clicks/taps while loading scripts. Under 200ms is good.
- First Contentful Paint (FCP) — how quickly anything appears on screen.
- Speed Index — how quickly your page visually fills in, overall.
- Time to Interactive (TTI) — when your page becomes fully usable, not just visible.
A score of 90–100 is considered fast, 50–89 needs improvement, and below 50 is considered poor — these thresholds are Google’s own, and apply the same way no matter what platform your site runs on.
Common Reasons Websites Are Slow
- Hosting or server infrastructure not built for performance
- No caching configured, or configured incorrectly
- Large, uncompressed images
- Too many third-party scripts (chat widgets, ads, analytics, tracking pixels)
- No CDN in front of the site
- Unminified or render-blocking CSS/JavaScript
- Platform-specific bloat — heavy page builders, unused plugins/apps, or unoptimized themes

Want This Fixed Instead of Just Diagnosed?
Running the test tells you what’s wrong. Fixing it is a different skill set — one we specialize in, primarily for WordPress sites, though many of these fixes apply broadly. Our team handles website performance optimization end-to-end: hosting review, caching setup, image and asset optimization, and Core Web Vitals fixes, typically completed within a few days.

Frequently Asked Questions
How do I check my website speed for free? Paste your site’s URL into the tool above and click Analyze. It works for any website on any platform, runs a real audit using Google’s PageSpeed Insights engine, and returns your score along with Core Web Vitals data — free, with no signup required.
Does this work for non-WordPress websites? Yes. This tool tests any publicly accessible URL, regardless of what platform, CMS, or framework the site is built on — WordPress, Shopify, Wix, Squarespace, Webflow, or fully custom code.
Why is my website slow? The most common causes are unoptimized hosting, missing or misconfigured caching, oversized images, too many third-party scripts, and render-blocking code. Run the test above to see which of these apply to your specific site.
What is a good website speed score? Scores of 90–100 are considered fast, 50–89 need improvement, and below 50 is considered poor by Google’s own thresholds. Mobile scores are typically lower than desktop for the same site, since mobile testing simulates a slower network and device.
Does website speed affect SEO rankings? Yes. Google has confirmed that Core Web Vitals are part of its ranking algorithm, and slower sites also tend to have higher bounce rates, which indirectly hurts rankings further — this applies to every platform equally.
How often should I test my website speed? Test after any major change — a new theme or template, a new plugin or app, a redesign, or a hosting migration — and periodically (monthly is reasonable) even without changes, since third-party scripts (ads, analytics, chat widgets) can silently slow a site down over time.
