Fallstudie
Detaillierter Leistungsbericht einer realen Website, erstellt mit VitaPulse
Über diese Studie
Dieser Bericht präsentiert die vollständigen Ergebnisse eines automatisierten Web-Performance-Audits, durchgeführt von VitaPulse mit dem Lighthouse-Engine. Er umfasst Bewertungen, Core Web Vitals, Optimierungsmöglichkeiten und detaillierte Diagnosen.
Globale Metriken
Audit-Deckblatt & Scores-Übersicht
The cover page presents the audited URL (www.e-xode.net), a full-page screenshot, and a summary of all Lighthouse scores for both mobile and desktop. Mobile: Performance 82, Accessibility 98, Best Practices 96, SEO 100. Desktop: Performance 78, Accessibility 98, Best Practices 96, SEO 100.
Inhaltsverzeichnis
The table of contents provides a navigable overview of all report sections. It lists every audit category with item counts — Core Web Vitals, Opportunities, Diagnostics, Performance Insights, Accessibility, Best Practices, SEO, Resources, and more — for both mobile and desktop analysis.
Mobile Scores & Core Web Vitals
The mobile analysis opens with 4 Lighthouse scores — Performance (82), Accessibility (98), Best Practices (96), SEO (100) — displayed as color-coded gauges. Below, a final screenshot and loading timeline visualize how the page renders over time. Core Web Vitals metrics follow: Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), Total Blocking Time (TBT), First Contentful Paint (FCP), and Speed Index.
Mobile Optimierungsmöglichkeiten
Two improvement opportunities are identified for mobile. Each includes a severity level, description, and estimated time savings. Key findings include server response time analysis and recommendations for optimizing resource delivery to improve loading performance.
Mobile Diagnose
28 diagnostic audits span 5 pages, providing in-depth mobile performance analysis. Key findings include excessive DOM size (827 elements), image sizing issues, CSS and JavaScript optimization, network round-trip delays, render-blocking resources, cache policy gaps, and detailed audits covering every aspect of page performance.
Mobile Ressourcen
A complete resource inventory showing 24 requests totaling 4.9 MB. Breakdown by type: Images (2.4 MB, 11 files), Scripts (2.3 MB, 3 files), Other (83.2 KB), Stylesheets (26.7 KB), and Fonts (22.0 KB). Third-party analysis identifies external dependencies.
Mobile Netzwerkanfragen
A detailed table of all 12 HTTP requests during mobile page load. Each request shows URL, resource type, protocol (h2), HTTP status, transfer size, resource size, and loading priority — providing full visibility into the network waterfall.
Mobile Layout-Verschiebungen & Script-Analyse
Layout shift analysis reveals 2 individual CLS events during page load with exact timestamps and impact scores. The script treemap visualizes JavaScript bundle sizes and unused code, helping identify optimization targets. Console output shows 1 hydration mismatch warning.
Mobile bestandene Audits
A comprehensive list of 94 successfully passed audits across all categories — Performance, Accessibility, Best Practices, and SEO. This confirms which standards the page already meets, from proper image formats and HTTPS usage to accessible labels, efficient caching, and search engine optimization.
Desktop Scores & Core Web Vitals
The desktop analysis mirrors the mobile structure. Scores: Performance (78), Accessibility (98), Best Practices (96), SEO (100). The loading timeline and final screenshot show desktop rendering behavior. Core Web Vitals are measured independently, often showing different values due to viewport and network conditions.
Desktop Optimierungsmöglichkeiten
Two improvement opportunities for desktop, including server response time (0.5s) and resource delivery optimizations. While similar to mobile findings, estimated savings and thresholds differ due to desktop's faster baseline performance.
Desktop Diagnose
29 diagnostic audits span 5 pages for desktop analysis. Findings include render-blocking resources (90ms estimated savings), image sizing optimizations (63 KB potential savings), network round-trip delays (250ms), JavaScript and CSS minimization, non-composited animation issues, and comprehensive performance audits.
Desktop Ressourcen
Desktop resource analysis shows the same 24 requests and 4.9 MB total. The breakdown mirrors mobile: Images dominate at 2.4 MB, followed by Scripts at 2.3 MB. Resource details help identify the heaviest assets for optimization.
Desktop Netzwerkanfragen
All 12 HTTP requests during desktop page load listed with full details — URL, type, protocol, status, transfer and resource sizes, and priority levels. Allows direct comparison with mobile network behavior.
Desktop Layout-Verschiebungen & Script-Analyse
Desktop layout shift analysis reveals 2 CLS events with combined scores. The script treemap shows JavaScript bundle composition and unused code percentages. Console reports 1 hydration mismatch warning — identical to mobile, confirming a code-level issue, not device-specific.
Desktop bestandene Audits
96 audits passed on desktop — 2 more than mobile — confirming strong overall compliance. The complete list covers performance optimizations, accessibility standards, security best practices, and SEO requirements the page successfully meets.
Wichtige Erkenntnisse
Perfekte SEO-Bewertung (100) und nahezu perfekte Barrierefreiheit (98) zeigen solide Grundlagen — dennoch gibt es Verbesserungspotenzial bei der Performance.
Ein 2,3 MB großes Hintergrundbild macht den Großteil der Seitengröße von 4,9 MB aus — moderne Formate (WebP/AVIF) könnten die Ladezeit erheblich verbessern.
6 statische Ressourcen haben keine Cache-TTL konfiguriert — das Hinzufügen geeigneter Cache-Header würde wiederkehrende Besuche beschleunigen.
VitaPulse erkennt automatisch Performance-Regressionen durch Vergleich mit einer Baseline — so werden Einbrüche frühzeitig erkannt, bevor sie Nutzer beeinträchtigen.
