Why aren't products indexed on my website e-co.ru?

Question

Search Engine Optimization

Hello!
Yandex does not want to index product pages. Some are indexed and some are not.
I wrote to them - they say no sanctions. It seems that robots do not prohibit - I don’t understand why!
I would be grateful if you tell me.

Answer 1

1. Loading products on the listing pages via Javascript
2. I did not find direct links to the catalog / product categories from the main page, only via Javascript
3. The catalog is not formatted with a clickable link in breadcrumbs

Answer 2

Descriptions are not copy-pasted?

Answer 3

and how much time has passed?
on the client site, Google indexed everything 1-2 weeks after launch, and Yandex indexed several pages without a catalog, and indexed the catalog after 2.5 months.
There can be many reasons: canonical urls are incorrect, cms has many duplicate pages, etc.
