What is the significance of the CNC transliteration standard?

Question

Search Engine Optimization

I check content of articles in Megaindex . Everything is fine, but he does not see the key phrase in the url, although it is there. Offers its own version with a different transliteration standard. This led me to the question, am I composing the transliteration url as correctly as possible? I know that there is 1 standard for Yandex, and another for Google. Will these search engines still recognize my URLs as CNC or will they think I'm a slob and didn't make them?
Here's an example:
My URL: kak-proverit-jestkii-disk
Megaindex offer: kak-proverit-zhestkij-disk
Tell me if it's worth redoing everything to some standard or is it better to leave it?
Transliteration has always done from the head as it seemed clear to me ...

Answer 1

It is best to look at how competitors write and what Google considers correct. You drive in the key, look at the issuance of Google and the highlighted yurls in bold in the issuance. Copy-paste and you have the correct url

Answer 2

jestkii is obviously bad, either jestkij or jestkiy, you can experiment in the search engines themselves.
