schema problem

Hello Rankmath representative.

I’m operator of aoptimer.com, and I have question about schema.

Few days ago, I’ve run ‘Google Structured Data test’ to check my website.
To check if anything was wrong, not only I run my website, but also I run test for big website like neilpatel.com & backlinko.com.

As I run the test, I can see huge differnece between my website and other website.
Maybe it could be not the ‘problem’, but I want to fix it.
