Looking at many russian websites (which are in cyrillic) the page names (file names html, php, etc) are mainly database results or they use short English names.
I.e.:
- tools.html and not toolsinrussian.html (here I not mean cyrillic)
Although the pages are fully in russian cyrillic, I not see the why of the Eng. page titles. Especially for russian only pages I would choose to name pages in the russian language as well (agree that this language need a lot of words, where in Eng. or other European language we can use two or three words in a keyword phrase.
Question is: Is it harming websites / pages when they are with russian file names?
Thanks for the feedback.
