Why Is My Site Slow?
Analyze whether your site slowness is due to Server/Infrastructure or Code/Theme issues.
Why Is My WordPress Site Slow? A Technical Deep Dive
Speed is critical for SEO and User Experience. But diagnosing slowness is hard because it can originate from two completely different sources: your web server (TTFB) or your frontend code (Client-side). Our tool helps you distinguish between the two.
How This Analysis Works
We measure the Time To First Byte (TTFB). This is the time it takes for your server to generate the HTML. High TTFB means slow database queries, lack of caching, or an underpowered server.
We download the raw HTML and analyze its size, structure, and embedded assets. Huge HTML size (DOM depth), excessive scripts, and uncompressed images slow down the browser rendering process.
We compare the server latency against the code complexity to calculate a 'Blame Percentage'. This tells you if you need to upgrade your hosting or optimize your theme.
Frequently Asked Questions
What is a good TTFB?
A TTFB under 200ms is excellent. Under 600ms is acceptable. Anything over 1 second is critical and needs immediate server-side optimization.
My server is fast but the site is slow?
This is a common 'Frontend Bloat' issue. It usually means your theme is loading too many unoptimized assets (CSS/JS) or large images, which chokes the visitor's browser.
How do I fix Server issues?
Enable Object Cache (Redis), use a Page Caching plugin (WP Rocket, Litespeed), or switch to a high-performance Managed WordPress Host.
