Typically websites perform poorly in China, and you will have a hard time finding out if you're not in China or do not have a team in China.

Ultimately your visitors in China will see the right screen, and you're seeing the left screen due to China's Great Firewall and the difference in the internet ecosystem in mainland China.

Feature roadmap

• Users can manually select what resources to optimize for China
• Based on the user’s geo-location and sending traffic from .com to .com/cn or .cn directly

Known issues / fixing soon

• ✅ “421 Misdirected Request” From Cloudflare - The screen record doesn’t show the website loading experience with the Cloudflare-protected site.
• ✅ “403 Forbidden” from cloudflare when open yammo optimized site
• Prevent optimized site auto redirect back to original site (e.g., visit <SITE-ID>.yammo.cn and auto redirect to original site e.g. XYZ.com)
• Videos and images are not optimized on your page
• Facebook / Twitter / Instagram logins are not optimized in China (they are all blocked in China)
