Assignment 10 – Web Systems 1 | Jonathan Hernandez
This is the official Lighthouse analysis for the GroovingSpace homepage, tested in Mobile Navigation Mode. The goal is to evaluate how the website performs on mobile devices in terms of performance, accessibility, best practices, and SEO.
The audit shows strong overall results, especially in Accessibility (96) and SEO (91). Performance scored lower at 62, primarily due to long JavaScript execution time and caching issues. These results indicate that the site is well optimized for mobile but could benefit from additional performance tuning.
The Performance score (62) was affected by JavaScript and rendering tasks that delayed loading times.
Lighthouse highlighted areas for improvement, such as reducing JavaScript execution time (2.3 s), minimizing main-thread work (3.0 s),
and eliminating render-blocking resources.
Additional recommendations included properly sizing images, assigning explicit width and height attributes, and
serving static assets with efficient caching policies.
These optimizations would help lower load times and improve Core Web Vitals.
The Accessibility score (96) demonstrates that GroovingSpace meets WCAG accessibility standards across most metrics.
The only warning detected was that some links do not have a discernible name, meaning that a few clickable icons or elements
should include accessible labels (e.g., aria-label) for screen readers.
Overall, the site provides clear navigation, strong text contrast, and appropriate semantic structure.
The Best Practices score (89) reflects solid web development standards. Lighthouse detected two minor issues: some images were displayed with incorrect aspect ratios, and browser errors were logged to the console. The console messages originated from a Chrome extension (VelocityInsight) and not from the site itself, meaning the actual codebase remains stable. Maintaining consistent image proportions and reviewing console logs can help achieve a perfect score.
The SEO score (91) confirms that the site follows modern search optimization practices. All headings, links, and structure are properly configured, and Lighthouse validated that structured data is valid. The only identified issue was the absence of a meta description tag, which would help search engines better summarize the page content. Adding this tag would likely raise the score above 95.
Overall, the GroovingSpace homepage performs well across all major categories. The responsive Bootstrap layout ensures full functionality and consistent design between desktop and mobile versions. Accessibility and SEO are nearly perfect, and performance can be enhanced with targeted optimization of JavaScript and image delivery.
This audit confirms that the site provides a smooth, intuitive user experience across all devices, meeting the project’s mobile-ready requirements and demonstrating effective web development practices.
