What to do with the nesting level of an aggregator with many categories?

Question

Search Engine Optimization

I noticed that for many popular commercial requests, the same Avito is inferior to ordinary online stores, and even VKontakte groups. But Avito has an incredible natural link mass, excellent behavioral characteristics ... and, it turns out, worthless seo-optimizers? Is the nesting level of the landing pages the reason for this failure? For example, in Avito it looks like this:

avito.ru/yaya/tovary_dlya_detey_i_igrushki/kupit-detskaya_mebel-ASgBAgICAUT~AZQJ

those. 4 nesting level, which is so-so ...
I would not want to just step on the same rake, because if they loom somewhere on the 2-3 page of the issue with multi-million dollar injections, then what can we say if there is no such stock of finance in remember?
If it’s a matter of the nesting level, then is it worth making the entire site with the 2nd nesting level at all, and encrypting the end of the links somehow, then parsing it in the router sequentially, considering which category the request belongs to, which heading, in which city and etc.? Whether there will be at the same time new rakes?

The second point is about the main strategy for promoting aggregators. Do I understand correctly, do we write the correct texts and shove them into headings or pages of end products, where a list of suppliers is already issued? Along the way, slowly increasing the quality of the reference mass. Is everything right? Has anything changed in 10 years?

What does this mean that you forgot to think
who the hell needs this in terms of SEO?
you can find any Zalupinsk and see that some kind of shit is in the top 1 there, and the whole dozen of the most visited sites in Russia are in the ass of the search, but there is only one problem in Zalupinsk, 3 people live and investing 100 thousand on SEO is pointless.
