Website homepage must be first link from every page of sub folders which are related in content?

[vtmoz]

Hi,

I have seen number of websites where they keep their website homepage as first link from every page of sub folders and even from sub domain pages some times. For example, giving website homepage as top navigational menu from every page in their blog. Will this helps in boosting the ranking of homepage if we link from sub folder or sub domain pages where they employ related content like blogs or help guides.

Thanks
