How Can We Improve on Many Subpages?

[arya]

Hello everyone, as an example, many subpages of https://enyakincekici.com/ such as nev?ehir oto çekici sivas oto çekici are on the first page. I think they have achieved this by only getting backlinks to the main page. When I looked at the subpages, I couldn't see any backlinks. How is this possible? Can you provide any insights?
