Internal links. Links for the main page
from:

According to the different types of making internal linking, there are different cases to set up links for the main page. On various sites I saw links for the main page:
1) On menu;
2) In bread crumbs;
3) In sidebar;
4) After the main text.
The result is that there could be about 2-4 links from one page to the main page. It`s not normal. So I`d like to know how you set up links for the main page? And how much per page considering that optimal variant is to set up 1 link 1 time per page....
