Does it make sense to make single-level urls?

Question

Search Engine Optimization

It is possible to make the most "flat" url structure on the site.
For example, instead of:

http://example.com/kino
http://example.com/politika
http://example.com/ecomonika

http://example.com/kino/operacia-i
http://example.com/politika/trump-obosralsya-na-publike
http://example.com/ecomonika/bitcoin-stoit-million

Do:

http://example.com/kino
http://example.com/politika
http://example.com/ecomonika

http://example.com/operacia-i
http://example.com/trump-obosralsya-na-publike
http://example.com/bitcoin-stoit-million

Thus, getting the shortest possible url.
Are there any real advantages and disadvantages to this?
So far, for me, the main drawback is the complication of technical support for the project. I can not decide whether it is worth the cost and whether it brings real benefits?

Answer 1

It seems like it’s better to have a structure than everything in one pile, at least in any metrics it’s more convenient to look at the structures, so it’s clear which modules are popular, which subsections (sections of news / articles) and which documents are in them

Answer 2

No, it doesn't make sense to do so. Yandex uses your url structure when indexing, and a slightly shorter url will not give any tangible benefit in ranking.

Answer 3

There is no point in doing a single-level url. On the contrary, it will only worsen your positions in the search.

1. Url does not affect the ranking of sites in any way. Representatives of Yandex and Google have already spoken about this more than once or twice.
   
2. On the other hand, it is very useful for a site to have sections and subsections. So it's better to create a hierarchical url.
   

For example, mysite.ru/russia is a section, the section has subsections mysite.ru/russia/politica/ and mysite.ru/russia/ecomonika/.
Why a large number of sections and subsections will help your site to advance in the search? Yes, because search engines love big sites, with a large number of headings! This for a search bot (and for a person) will mean that your site can solve all the user's problems in this topic.

In addition, sections need to be created under a pre-compiled semantic core. First, we create the core, build a hierarchy in it, and on the basis of this hierarchy we create sections and subsections on the site.

The url should make it clear which section the article belongs to.
And in general, it is not clear why you want to abandon the hierarchy and make the site a flat structure? Then "Webmaster" will tell you that there are no sections on your site and that your site is "flat".
