What's the difference between Speed Surgeon and Google PageSpeed Insights?

PageSpeed Insights gives you a score and general recommendations. Speed Surgeon goes deeper — it identifies root causes behind each problem, quantifies the exact impact in seconds and milliseconds, and gives you a prioritized action plan with specific instructions. Think of it as the difference between a blood test and a complete medical examination.

How often should I run a speed analysis?

We recommend a thorough analysis at least once a month, and always after major site changes — new plugins, design changes, new third-party scripts or CMS updates. Core Web Vitals can change quickly, and a new chat widget or analytics script can suddenly destroy performance.

Can Speed Surgeon fix the problems automatically?

Speed Surgeon diagnoses and gives you exact instructions to fix each problem, but implementation must be done by you or your developer. Some fixes are simple (compressing an image), while others require technical expertise (optimizing JavaScript bundling or configuring caching).

Does the tool support analysis of single pages or the entire site?

Both. You can analyze a single URL for quick diagnosis, or run a full site analysis that identifies the slowest pages and gives you an overall picture of performance. For large sites we recommend starting with the most important pages — homepage, product pages and landing pages.

Speed Surgeon

What it does

Analyzes site performance and provides concrete recommendations to improve load time, Core Web Vitals and user experience.

Slow websites kill conversions, SEO rankings and user experience — but most don't know what actually makes the site slow

Google has made page speed a direct ranking factor through Core Web Vitals. A page that loads in 5 seconds instead of 2 loses up to 53% of mobile visitors. But speed optimization is complex — it could be large images, unoptimized JavaScript, slow server response, render-blocking CSS, or a combination of everything. Without a precise diagnosis you end up fixing the wrong things while the real problem remains unsolved.

Core Web Vitals (LCP, FID, CLS) are direct ranking factors — poor scores mean lower visibility in Google
Each extra second of load time increases bounce rate by 32% — slow pages cost you visitors and conversions
Generic speed advice like "optimize images" doesn't help when you don't know which images or which pages are the problem
Many developers fix symptoms instead of root causes — they compress images while the real problem is render-blocking JavaScript

Precise diagnosis of speed issues with concrete, prioritized recommendations you can implement immediately

Speed Surgeon analyzes your website like a doctor analyzes a patient — systematically, thoroughly and focused on root cause. The tool identifies exactly what makes the page slow, quantifies the impact of each problem, and gives you a prioritized action plan. Instead of general advice you get specific instructions: "This 450KB JavaScript file blocks rendering and adds 1.8 seconds load time — here's how to fix it."

Core Web Vitals analysis: detailed review of LCP, FID/INP and CLS with specific recommendations to pass Google's thresholds
Resource analysis: identifies the biggest performance thieves — images, JavaScript, CSS, fonts and third-party scripts with exact size and impact
Render analysis: maps render-blocking resources, critical rendering path and suggests optimal loading order
Prioritized action plan: ranks all issues by potential impact so you know exactly what to fix first for the biggest improvement

Features

Mobile vs desktop analysis: separate speed reports for mobile and desktop because problems are often completely different — mobile is almost always worse
Third-party script audit: identifies external scripts (analytics, chat widgets, ads) that slow the page and suggests alternatives or lazy-loading
Image optimization report: analyzes every image on the page — format, size, dimensions and compression — with specific recommendations for each one
Historical performance log: track Core Web Vitals over time to see if your changes actually improve performance or if new problems have appeared

How it works

Enter the URL you want to analyze — Speed Surgeon runs a complete performance test on both mobile and desktop with real browser data
The tool identifies all performance bottlenecks, quantifies the impact of each problem and maps the root causes behind slow loading
Get a prioritized action plan with specific instructions for each problem — sorted by potential impact so you know what to fix first

Use cases

Web developers needing to diagnose and fix speed issues before a launch or after Core Web Vitals have fallen below Google's thresholds
SEO specialists wanting to document performance improvement opportunities for clients with concrete numbers on potential impact on rankings and conversions
E-commerce businesses where each extra second of load time directly affects conversion rate and revenue — especially on mobile

Why use Speed Surgeon?

Page speed is no longer a "nice to have" — it's a direct ranking factor in Google. Since Core Web Vitals became part of the ranking algorithm, websites with poor performance have seen noticeable drops in visibility. Speed Surgeon gives you the precise diagnosis you need to fix problems efficiently instead of guessing.

What makes Speed Surgeon unique is the focus on root causes and prioritization. Instead of a long list of general advice you get a ranked action plan where each problem is quantified with exact impact. You know that fixing problem #1 saves 1.8 seconds while problem #5 only saves 0.1 seconds — so you spend your time where it has the biggest effect.

For Nordic websites mobile performance is especially critical. Nordic users have high mobile share and high expectations for speed. An online store that loads in 4 seconds on mobile loses half of potential customers before they even see the product. Speed Surgeon helps you deliver the speed users expect.
