We’ve repeatedly seen a major performance issue caused by embedded HighLevel forms — especially on mobile. After extensive testing, we identified that forms in the footer or hero section can reduce mobile Lighthouse scores by 20–30 points.

Example: Our homepage consistently scored below 70 on mobile. After removing just the embedded newsletter form, the score jumped into the 90s. This aligns with issues we also had 3 years ago on a WordPress site using the same forms. The core problems include:

Delay in First Contentful Paint (FCP) and Largest Contentful Paint (LCP)

Render-blocking form-related CSS/JS

Unnecessary third-party scripts loaded even when forms are not visible

~4–5 seconds added to visual rendering

This affects not only UX but also SEO and conversion rates. The desktop performance remains high, so this is clearly a mobile-specific bottleneck.

🟠 Suggested Improvements:

Lazy load forms only after interaction (e.g., click or scroll)

Defer all form-related JavaScript (e.g., libphonenumber, intlTelInput)

Avoid loading hidden forms during initial paint

Reduce bundle size by loading only necessary input types

Please prioritise this — we’re seeing this across multiple websites and it’s harming performance out of the box.
