How to use page names correctly?

Question

Search Engine Optimization

Good day, friends. There is a site with page names /mypage1.php, /mypage2.php and so on.
What is the correct name for these page files in terms of search engine optimization?
As far as I understand, it would be more correct to name these pages through a dash, for example: /okna-plastikovie.php, /okno-derevyannie.php and so on, is this correct?
How more loyal for search engines to call?
Thanks in advance for your reply.

Hey!
That's right, we need titles in transliteration that convey the essence of what is on the page, as short as possible, but including the main high-frequency keywords. You can use dashes instead of spaces. At the end of .php it is better to remove.
