What is the best way to give links on the site for SEO? Is it better to use Cyrillic, transliteration or English?

Question

Search Engine Optimization

For example:
mysite.com/service/alarm-installation
mysite.com/service-alarm-installation
mysite.com/services/alarm-installation
mysite.com/alarm-installation
mysite.com/uslugi/ustanovka-signalizacii

What is better and in what difference?

Answer 1

Russians are not allowed, there are more problems with them than good.
The Russian language is supported by the Internet, BUT this does not mean that there are no problems from it, the Internet was developed outside of UTF-8 with all the consequences, yes they work, but problems are possible, moreover, in completely different places, there are no Russian letters, no problems.
do not forget that all daemons, services, modules, etc. are written by the English-speaking community that does not know a word about encodings at all, they simply never encounter this problem in their lives.
so without other advantages from the Russian language, do everything in English
mysite.com/uslugi/ustanovka-signalizacii/
because it can be transliterated by a robot.
also note that there is a closing / at the end.
The logic is as follows if it is a .pdf file then it does not close
all the others

Answer 2

It is better not to use Cyrillic. There is no particular harm, but no benefit either: Cyrillic in the URL - is it good for SEO?
Of the options given, the best options are:
mysite.com/service/alarm-installation or mysite.com/uslugi/ustanovka-signalizacii
, provided that the service or uslugi page exists.
If there is no nesting in the site structure, then mysite.com/service-alarm-installation
Transliteration or translation is a matter of taste.

Answer 3

if the link is not copied - you can Russian
