hey yo? does secondary pages backlinks count as domain backlinks?

ex: my domain has 120k backlinks

I want to get 20k backlinks to a secondary page (domain.com/page/)

will that 20k backlinks count to domain so I will have 140k instead of 120? or how does it work?

Yeah they will ... but it depends on the quality/nature of those links if it does any good

Yes, they will. Just pay attention to quality of those backlinks. Try to grow them organically
