React Developer Needed to Fix AdSense on SPA Navigation + Zero CLS Optimization

I have a React Single Page Application SPA where Google AdSense works only on a full page reload, but fails to render when navigating between pages using React Router. I need an experienced React developer who fully understands how AdSense behaves in SPAs to fix this issue and ensure ads load consistently on every route change. Right now: Ads load correctly after a hard refresh On SPA navigation, ad slots remain empty or fail to reinitialize adsbygoogle.push often runs without creating an iframe Some slots rely on fallbacks instead of showing real ads Your main tasks: 1. Fix AdSense in SPA Navigation Ensure the AdSense script is re-initialized safely when routes change Clean up old ins elements and stale data-adsbygoogle-status attributes Implement a reliable ad remount cycle so ads always render without a full refresh Prevent duplicate script loads or dead pushes 2. Zero Layout Shift Zero CLS Add stable fixed-height ad containers Prevent content from jumping when ads load Make the site fully compliant with Core Web Vitals Improve mobile experience and Lighthouse performance 3. Performance Optimization Optimize script loading and lazy loading of components Improve LCP and INP by removing unnecessary re-renders Ensure smooth, fast navigation across the SPA 4. Clean, Maintainable React Code Refactor the current ad component if needed Ensure the solution is stable and scalable Follow AdSense or GAM best practices I need someone who has real experience integrating AdSense or Google Publisher Tags into SPAs.
