Upon reviewing the Infusion Technologies website, several issues could be impacting mobile performance, leading to scores below 90. Here are the identified problems and recommended solutions:

    Loading Speed:
        Issue: The site may have large images or scripts that delay loading times.
        Solution: Optimize images for web use (e.g., using formats like WebP) and defer loading of non-essential scripts.

    Responsive Design:
        Issue: Some elements may not adapt well to smaller screens.
        Solution: Ensure CSS media queries are used effectively to enhance responsiveness across different device sizes.

    Mini fication of Resources:
        Issue: Un mini fied CSS and JavaScript can lead to slower loading times.
        Solution: Use tools to mini fy CSS and JavaScript files to reduce their size.

    Caching:
        Issue: Lack of proper caching can increase load times for returning visitors.
        Solution: Implement browser caching and consider a Content Delivery Network (CDN) for faster content delivery.

    Reduce Redirects:
        Issue: Excessive redirects can slow down performance.
        Solution: Minimize redirects to enhance the loading speed of pages.

    Server Response Time:
        Issue: A slow server response can negatively impact overall speed.
        Solution: Evaluate hosting options and consider optimizing server configurations.

    Core Web Vitals:
        Issue: Poor scores in metrics like Largest Content ful Paint (LCP) and Cumulative Layout Shift (CLS).
        Solution: Focus on improving LCP by optimizing images and server response times, and stabilize layout shifts by using size attributes for images and ads.

Implementing these solutions should help achieve a mobile performance score of 90+. For a detailed analysis and continuous monitoring, tools like Google PageSpeed Insights or GTmetrix can be beneficial.
