Executive Summary
RiGi GROUP delivered a real-time AI agentic SEO audit for a QSR brand struggling with high mobile bounce rates and limited search visibility. Leveraging agentic workflows — AI-driven diagnostics, automated tooling, and iterative live-site fixes — we achieved a 45% reduction in Largest Contentful Paint (LCP), boosted Google Lighthouse mobile performance from 84 to 98, and unlocked voice search rich results. These rapid, measurable wins demonstrate how AI-powered SEO enhances user experience, lowers bounce, and improves organic rankings for local/intent queries like “subs near me.”
The Challenge
Elevated bounce rates on mobile — the primary channel for high-intent local QSR searches — were costing the brand visibility and conversions.
Mobile load times averaged 3.8 seconds LCP, exceeding Google's good threshold of ≤ 2.5s
Cumulative Layout Shift (CLS) at 0.22 caused visual instability (good threshold: ≤ 0.1)
First Input Delay (FID) at 180ms hindered interactivity (legacy good threshold: < 100ms)
Overall Lighthouse mobile score: 84/100
Missing structured data limited voice search readiness and rich snippets
