The website
It uses your domain for search engines and for people who arrive from a link. It explains the company, products, and services, and leaves an inquiry or purchase path.
The mini program
It lives in WeChat for people who already talk to you there. The flow follows the agreement, and the materials and a test account are ready before review.
Keep them aligned
Use one set of product names, prices, and contact details. The site can point to the mini program, and the mini program can name the site.
Review
Listing depends on WeChat. If a rejection sits inside the agreed scope, the pages are revised from that feedback and submitted again.
