A 98 PageSpeed score won't save a bad website.
Google PageSpeed Insights is excellent at what it does: lab-testing your load performance and surfacing Core Web Vitals data from real Chrome sessions. But a blazing-fast site with a confusing headline, no social proof, and a broken call-to-action still loses every visitor it loads. Speed is table stakes — not a strategy. Roasted is the AI-powered website roast that critiques your entire site across 8 pillars covering 15+ dimensions and attributes: design quality, copywriting, trust signals, conversion optimization, SEO structure, mobile UX, accessibility, security headers, network performance, and more. Where PageSpeed tells you how quickly the page arrives, Roasted tells you whether what arrives is worth staying for. Here is the full comparison of these two website analysis tools and when to use each.

The full story: PageSpeed Insights vs Roasted for website quality
What PageSpeed Insights actually measures — and what it does not
Google PageSpeed Insights is one of the most widely used web performance tools on the internet, and for good reason. It combines two powerful data sources into a single report. The first is Chrome User Experience Report (CrUX) field data, which aggregates real-world performance metrics from millions of Chrome browser sessions across the last 28 days. This gives you authoritative numbers for Core Web Vitals — Largest Contentful Paint (LCP), First Input Delay (FID), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP) — based on how actual visitors experience your site. No synthetic test can replicate this level of real-world accuracy.
The second data source is Lighthouse, Google's open-source lab testing engine that runs a simulated page load on a throttled connection and scores your site from 0 to 100 across performance, accessibility, best practices, and SEO categories. Lighthouse identifies specific technical issues like render-blocking resources, oversized images, missing meta descriptions, and JavaScript execution bottlenecks. Together, CrUX field data and Lighthouse lab data give you the most authoritative picture of your site's loading performance available anywhere.
But here is the critical gap: PageSpeed Insights has zero opinion on whether your website is actually effective. It does not evaluate your headline, your value proposition, your call-to-action placement, your social proof, your visual design quality, your pricing clarity, your form friction, or your trust signals. A landing page that loads in 1.2 seconds but has a confusing headline, no testimonials, and a call-to-action buried below three paragraphs of jargon will score beautifully in PageSpeed Insights — and fail catastrophically at converting visitors. PageSpeed measures the vehicle. Roasted measures the destination.
The myth of the perfect PageSpeed score
There is a pervasive belief in the web development community that achieving a 90+ or even 100 PageSpeed score is the ultimate goal of website optimization. This belief is understandable — Google has made Core Web Vitals a confirmed ranking signal, and a green score in PageSpeed Insights feels like a definitive stamp of quality. But this belief conflates performance with effectiveness, and the distinction matters enormously for business outcomes.
Consider this scenario: two competing SaaS landing pages target the same keyword. Site A scores 98 in PageSpeed Insights with perfect Core Web Vitals. Its headline reads 'Next-Generation Synergistic Platform Solution' over a stock photo, with a tiny sign-up link in the footer. Site B scores 78 in PageSpeed — slightly slower, minor CLS issues — but it has a crystal-clear headline, three customer testimonials above the fold, a prominent free-trial button, and trust badges from recognizable brands. Which site converts more visitors? The answer is obvious, and it is not the one with the higher PageSpeed score. Performance is a hygiene factor. Once you cross the threshold of 'fast enough' (generally sub-3-second LCP), further speed improvements yield diminishing returns compared to improvements in messaging, design, and conversion optimization.
This is precisely where Roasted fills the gap. After PageSpeed Insights confirms that your site loads quickly and passes Core Web Vitals thresholds, Roasted evaluates the eight qualitative dimensions that determine whether those fast-loading visitors actually do anything useful on your site. The combination of both tools gives you a genuinely complete picture of website quality — something neither tool can provide alone.
Why fast websites still fail to convert visitors into customers
The average website visitor forms a first impression in approximately 50 milliseconds — long before any performance metric is consciously registered. That first impression is driven entirely by visual design quality, layout clarity, and perceived trustworthiness. A site that loads in 1.5 seconds versus 2.5 seconds may see marginal bounce rate improvements, but a site with a compelling headline versus a confusing one will see conversion rate differences of 200% or more. PageSpeed Insights is completely blind to these qualitative factors because they cannot be measured by automated performance testing.
Roasted's AI agents evaluate exactly these qualitative signals. The Design Agent assesses visual hierarchy, whitespace usage, color contrast, and layout professionalism. The Copy Agent evaluates headline clarity, value proposition strength, call-to-action language, and overall persuasion quality. The Trust Agent looks for social proof, team visibility, contact information, security indicators, and credibility signals that visitors subconsciously scan for before trusting a website with their email address or credit card. The Conversion Agent analyzes CTA placement, form friction, pricing transparency, and the overall conversion funnel. None of these dimensions appear anywhere in a PageSpeed Insights report.
The practical implication is clear: if you are only running PageSpeed Insights, you are optimizing for one dimension of website quality while leaving more than a dozen others completely unexamined. That is like training for a decathlon by only practicing the 100-meter sprint. You might be fast, but you are going to lose the overall competition to someone who trains across all events.
How Roasted fills the qualitative gap PageSpeed Insights leaves behind
Roasted was designed from the ground up to audit the dimensions of website quality that automated performance tools cannot touch. When you submit a URL to Roasted, specialized AI agents evaluate your site simultaneously across more than 15 dimensions: design, copy, SEO structure, trust and credibility, conversion optimization, mobile UX, security, performance, accessibility, social proof, network analysis, and more. Each agent produces specific, actionable findings — not abstract scores — with plain-English explanations of what is wrong and exactly how to fix it.
One of the most powerful differentiators is that every Roasted finding includes a paste-ready fix prompt designed for AI coding assistants like Claude, ChatGPT, or Cursor. Instead of reading a vague recommendation like 'improve your heading structure,' you get a specific prompt you can paste directly into your code editor that rewrites your heading to be clearer, more compelling, and better optimized for search engines. This dramatically reduces the time between identifying a problem and shipping a fix — from hours of interpretation down to seconds of copy-paste.
Roasted also generates a permanent shareable link for every audit. Unlike PageSpeed Insights, where results live at a session URL that can expire or change with subsequent tests, Roasted audit links are permanent and designed to be shared with developers, designers, clients, and stakeholders. This makes Roasted particularly valuable for agencies and freelancers who need to communicate website issues to clients in a format that is engaging, easy to understand, and actionable — rather than a wall of technical performance metrics.
Real scenarios where a 98 PageSpeed score masks critical website problems
Scenario one: a SaaS startup spends three weeks optimizing their marketing site to hit a 98 PageSpeed score. They ship compressed images, code-split their JavaScript bundles, implement lazy loading, and configure edge caching. Their Core Web Vitals are flawless. But their homepage headline still says 'Welcome to Our Platform' — a phrase so generic it could describe any company in any industry. Their free trial button is gray text on a white background below the fold. They have zero customer testimonials and no trust badges. PageSpeed says the site is exceptional. Roasted would flag the vague headline, invisible CTA, missing social proof, and absent trust signals as critical issues — because those are the reasons the site's conversion rate is 0.3% despite loading in under two seconds.
Scenario two: an ecommerce store achieves green scores across all Core Web Vitals. But their product pages have no customer reviews, their checkout form asks for twelve fields of information before showing the total price, their mobile menu requires three taps to reach any product category, and their security page is a broken link. PageSpeed Insights reports nothing wrong. Roasted's Trust Agent flags the missing reviews, the Conversion Agent highlights the excessive form friction, the Mobile Agent identifies the navigation depth problem, and the Security Agent catches the broken security page.
These are not edge cases — they are the norm. The overwhelming majority of underperforming websites have acceptable PageSpeed scores. Their problems are qualitative, not quantitative, and no amount of performance optimization will solve them. Running Roasted alongside PageSpeed Insights ensures you catch the full spectrum of issues that determine whether your website actually achieves its business goals.

🔥 Get your free roast — 30 seconds, no accountWhat happens after the page loads
First impressions happen in 50ms
PageSpeed measures how quickly your page arrives. Roasted measures whether what arrives is any good — design quality, visual trust, and layout clarity that visitors judge in milliseconds, long before they consciously register how fast the page loaded.
Headlines convert, not load times
The number one reason visitors leave without converting is not speed — it is a weak value proposition. Roasted's Copy Agent rates your headline, sub-copy, and CTAs on actual persuasion quality, something PageSpeed Insights has no concept of.
Trust kills more conversions than latency
Missing social proof, no visible team page, buried contact info — these drive bounce rate more than a 200ms LCP difference ever will. Roasted flags all of it. PageSpeed is completely blind to it.
SEO beyond Core Web Vitals
PageSpeed does not check your title tag quality, meta description effectiveness, Open Graph images, or heading hierarchy. Roasted's SEO Agent evaluates the signals Google uses for snippets, rich results, and ranking beyond just performance.
The conversion audit PageSpeed skips entirely
Where is your CTA? Is it above the fold? Is your pricing clear? Are you asking for too much information in your form? Roasted's Conversion Agent answers every one of these questions that PageSpeed Insights was never designed to ask.
Permanent results you can actually share
PageSpeed results live at a session URL that can expire or change with each test run. Roasted generates a permanent shareable audit link you can send to a developer, designer, or client — with paste-ready fix prompts for every finding.
Pricing comparison: PageSpeed Insights vs Roasted
PageSpeed Insights is completely free — it is a Google product built to improve web performance across the entire internet. Roasted offers a generous free tier for individual developers plus paid plans that unlock advanced workflow features. Since the two tools measure fundamentally different dimensions of website quality, most teams use the free tiers of both together.

When to use each tool: PageSpeed Insights vs Roasted
Use PageSpeed Insights when you need to...
Core Web Vitals monitoring and field data
PageSpeed Insights is the only free tool that surfaces Chrome User Experience Report (CrUX) data — real-world performance metrics aggregated from millions of Chrome browser sessions over the past 28 days. This is the authoritative source for LCP, FID, CLS, and INP field measurements.
Lighthouse lab testing and performance scoring
When you need a detailed Lighthouse lab report with specific performance bottleneck identification — render-blocking resources, unoptimized images, excessive JavaScript execution time — PageSpeed Insights provides the deepest performance diagnostics available for free.
Performance regression testing after deployments
After shipping code changes, PageSpeed Insights helps you verify that Core Web Vitals have not regressed. Running a quick test after each deployment catches performance regressions before they impact your Google search ranking signals.
Understanding Google ranking signal compliance
Since Core Web Vitals are a confirmed Google ranking factor, PageSpeed Insights is the definitive tool for checking whether your site meets the thresholds Google uses to evaluate page experience as a ranking signal.
Debugging specific loading performance bottlenecks
When you know your site is slow and need to identify exactly why — whether it is server response time, render-blocking CSS, uncompressed assets, or layout shifts — Lighthouse diagnostics in PageSpeed Insights provide granular technical detail.
Use Roasted when you need to...
Full website quality audit across 8 pillars covering 15+ dimensions and attributes
When you need a holistic assessment of your website beyond just speed — covering design quality, copywriting effectiveness, SEO structure, trust signals, conversion optimization, mobile UX, security, accessibility, and more — Roasted provides the comprehensive audit that performance-only tools cannot.
Design review and visual quality assessment
Roasted's Design Agent evaluates visual hierarchy, whitespace, color usage, typography, and overall design professionalism. This is critical for landing pages, marketing sites, and any page where first impressions directly impact conversion rates.
Copywriting critique and messaging optimization
The Copy Agent rates your headline clarity, value proposition strength, CTA effectiveness, and overall persuasion quality. For marketing teams and founders, this is often the highest-impact feedback they receive from any audit tool.
Conversion funnel analysis and optimization
Roasted's Conversion Agent analyzes CTA placement and visibility, form friction, pricing transparency, and the overall path from visitor to customer. This directly impacts revenue in ways that performance optimization alone never will.
Shareable client reports with actionable fix prompts
Every Roasted audit generates a permanent shareable link with paste-ready fix prompts for Claude, ChatGPT, or Cursor. Agencies and freelancers use these to communicate issues to clients and developers in a format that drives immediate action.
The best approach? Use both.
The most effective website audit workflow combines both tools. Start with PageSpeed Insights to verify your Core Web Vitals field data and Lighthouse performance scores — fix any regressions or failures first, since slow sites lose visitors before they even see your content. Then run Roasted to audit the qualitative dimensions that PageSpeed cannot evaluate: design, copy, trust, conversion, and SEO structure. Together, the two tools cover every meaningful dimension of website quality in under 60 seconds of total testing time. Most professional web teams run both tools after every major deployment.
5 advantages Roasted has over PageSpeed Insights
Fifteen-plus audit dimensions versus performance only
PageSpeed Insights evaluates one dimension of website quality: loading performance. Roasted evaluates more than 15 dimensions simultaneously — design, copy, SEO, trust, conversion, mobile UX, security, performance, accessibility, social proof, network analysis, and more. This means Roasted catches the qualitative issues that drive 80% or more of visitor bounce decisions but are completely invisible to performance-only tools. A website is not a speed test — it is a persuasion engine, and Roasted audits the entire engine.
AI personality that makes audits fun and shareable
PageSpeed Insights produces a clinical, technical report designed for developers. Roasted delivers its feedback with a sharp, witty AI personality that makes audits genuinely entertaining to read — and much more likely to be shared with colleagues, clients, and on social media. This is not just a cosmetic difference. Audit reports that get shared are audit reports that get acted on. The viral shareability of Roasted results means findings are far more likely to reach the decision-makers who can authorize fixes.
Actionable copy and design feedback in plain English
PageSpeed Insights recommendations are heavily technical: "Eliminate render-blocking resources," "Serve images in next-gen formats," "Reduce unused JavaScript." These are useful for developers but meaningless to founders, marketers, and designers. Roasted provides plain-English feedback anyone can understand: "Your headline promises nothing specific — replace it with your core value proposition," or "Your CTA button is the same color as your background and invisible on mobile." This accessibility means every stakeholder on the team can understand and act on Roasted findings without needing a developer to translate.
Paste-ready fix prompts for AI coding assistants
Every finding in a Roasted audit includes a paste-ready prompt optimized for Claude, ChatGPT, or Cursor that generates the exact code change needed to fix the issue. This collapses the feedback-to-fix cycle from hours of interpretation and implementation down to seconds of copy-paste. PageSpeed Insights tells you what is slow. Roasted tells you what is wrong and gives you the exact prompt to fix it — whether the issue is a weak headline, a missing trust badge, a buried CTA, or a misconfigured security header.
Permanent shareable result links that never expire
PageSpeed Insights results exist at a URL tied to your testing session that can expire, change between runs, and cannot be reliably bookmarked or shared as a persistent reference. Roasted generates a permanent, unique URL for every audit that serves as a lasting record of your website's quality at that point in time. These links are designed for sharing with developers, designers, clients, and stakeholders. For agencies managing dozens of client sites, this permanence transforms Roasted audits from one-time tests into an ongoing quality tracking system.

Is Roasted a replacement for Google PageSpeed Insights?
No, and it is not trying to be. PageSpeed Insights is the gold standard for web performance measurement, particularly because it surfaces Chrome User Experience Report (CrUX) field data that reflects real-world loading behavior across millions of Chrome sessions. Roasted covers everything PageSpeed ignores: design quality, copywriting effectiveness, trust and credibility signals, conversion funnel analysis, and SEO structure beyond Core Web Vitals. The smartest workflow is to run both tools. Use PageSpeed Insights to nail your performance scores and Core Web Vitals, then use Roasted to audit the 8 pillars and 15+ additional dimensions that determine whether those fast-loading visitors actually convert into customers.
Does Roasted measure Core Web Vitals like PageSpeed Insights does?
Roasted's Speed Agent evaluates key performance signals including estimated Largest Contentful Paint (LCP), render-blocking resources, unoptimized images, and JavaScript bundle weight. However, it does not connect to the Chrome User Experience Report (CrUX) the way PageSpeed Insights does, so it cannot provide authoritative field data from real Chrome sessions. For definitive Core Web Vitals field measurements — the exact numbers Google uses as ranking signals — PageSpeed Insights remains the canonical source. Roasted focuses its energy on the seven other audit dimensions that PageSpeed Insights does not touch at all.
My PageSpeed score is 95 or higher. Do I still need Roasted?
Almost certainly yes, and this is one of the most common misconceptions in web development. A high PageSpeed score means your site loads quickly and passes Core Web Vitals thresholds — that is genuinely important for user experience and search ranking. But performance is only one of at least 15 dimensions that determine whether a website actually succeeds. Sites with perfect PageSpeed scores routinely fail on design trust, headline clarity, call-to-action placement, social proof, conversion friction, and SEO meta quality. Roasted surfaces all of those gaps. Think of it this way: a restaurant that opens its doors instantly but serves mediocre food will still fail. Speed gets visitors in the door, but everything else keeps them there.
How does pricing compare between Roasted and PageSpeed Insights?
PageSpeed Insights is completely free with no usage limits — it is a Google product designed to encourage better web performance across the internet. Roasted offers a free tier with up to three audits per day, which is enough for most individual developers and small site owners. The Plus plan at $29.99 per month unlocks unlimited audits, multi-page crawl, and PDF export for freelancers and small teams. The Pro plan at $99 per month adds white-label reports, API access, and priority processing for agencies managing multiple client sites. Since PageSpeed Insights and Roasted measure fundamentally different things, most teams use the free tiers of both tools together.
Can I use Roasted and PageSpeed Insights together in my workflow?
Absolutely, and that is the recommended approach. A comprehensive website audit workflow looks like this: first, run PageSpeed Insights to check Core Web Vitals field data and Lighthouse lab scores, fixing any performance regressions. Then run Roasted to audit the qualitative dimensions — design, copy, trust, conversion, SEO structure, mobile UX, and security. Roasted generates a permanent shareable link with paste-ready fix prompts for each issue, so you can hand the full audit to a developer or designer and they can start fixing immediately using Claude, ChatGPT, or Cursor. Together, the two tools cover every meaningful dimension of website quality in under 60 seconds total.
What is an AI website roast and why is it better than a PageSpeed score?
An AI website roast is Roasted's approach to website analysis — a narrative, personality-driven critique that evaluates your site the way a brutally honest human expert would. Unlike PageSpeed Insights, which produces a single numeric score focused on loading performance, Roasted delivers detailed findings across 8 pillars spanning 15+ quality dimensions with specific, actionable recommendations for each issue. The roast format makes findings engaging and memorable, which means they actually get shared with teammates and acted upon. Every finding also includes a paste-ready prompt for AI coding assistants like Claude Code or Cursor, so you can go from reading the critique to deploying the fix in minutes. A PageSpeed score tells you one number. A Roasted roast tells you a story about why your site is failing and exactly how to fix it.
