How to fix it

Optimize your landing page:

1. Compress images: Use WebP format, max 200KB per image.
2. Minimize scripts: Remove unnecessary JavaScript and CSS.
3. Use a CDN: Serve assets from edge locations near your audience.
4. Consider Instant Pages: TikTok’s Instant Page feature pre-loads your landing page for sub-second load times.
