How to make a shortened url when creating a post?

Question

WordPress

Now, by default, when adding a record, its url becomes the same as the title (only in Latin), but you need to somehow make the url cut to 3 words, due to SEO. What is the best way to do this? I tried to insert in functions.php

function new_excerpt_length($length) {
  return 3;
}
add_filter('excerpt_length', 'new_excerpt_length');

did not help

This is not standard behavior. By default, the url takes the title unchanged. And one of the plug-ins turns it into Latin. In it, you can see how to modify the url
