Optimization Recommendations

Core Web Vitals Improvement Needed

Your website's speed grade is <strong>F</strong>. This may negatively impact your rankings on Google. Improving load times to under 2.5 seconds is critical for mobile users.

Optimize Images & Media

Ensure all images are compressed and served in modern formats like WebP. Lazy loading images can also significantly improve initial load times for users on slower connections.
