Build links pointed to subpages

[Sabrina Gage]

If I build links pointed to subpages, is it helpful to increase the page rankor quality of our home page?

[C.Rebecca]

Yes, Internal linking is very helpful in improving the SERP rankings of sub pages. It also improves the overall reputation of your website.

I think original poster was referring to deep linking, not internal linking, but both are equally important and useful for the ranking.
