Doubts about the technical URL structure

[HolgerL]

Hello,

first we had this structure

Categorie: https://www.stoneart-design.de/armaturen/

Subcategory: https://www.stoneart-design.de/armaturen/waschtischarmaturen/

Oft i see this

https://www.xxxxxxxx.de/badewelt/badmoebel/

But i have heard it has something to do with layers so google can index it better, is that true ?

"Badewelt" is an extra layer ?

So i thought maybe we can better change this to:

https://www.stoneart-design.de/badewelt/armaturen/

https://www.stoneart-design.de/badewelt/armaturen/waschtischarmaturen/

and after seeing that i thought we can do it also like this so the keyword is on the left, and make instead "badewelt" just a "c" and put it on the back

https://www.stoneart-design.de/armaturen/c/

https://www.stoneart-design.de/armaturen/waschtischarmaturen/c/

I dont understand it anymomre which is the best one, to me its seems to be the last one

The reason was about this: this looks to me keyword stuffing: Attached picture

Google indexed not the same time the same url, so i thougt with this we can solve it

Also we can use only the word "whirlpools" in de main category and the subs only the type without "whirlpools" in text

thanks

Regards,

Marcel
