Home page linking: If I indicate all keyword for my home page. My home page can get quick back link, as a result good page rank and good position in SERP. Most of the directory and blog, forum don’t not allow deep page linking for free, but it is very easy to get link for home page and popularize it and get result. Deep page link: If I link all my keyword to my home page, visitor may come through a link and get confuse in home page. Suppose I have a post 3 level deep, but through my keyword visitor came to homepage, and cannot find directly that post, user frustration and bounce rate will increase. However it is very tough to get back link for deep page link. What you think is the right process? Concentrate only on home page or popularize deep category page individually. Thanks for spearing your valuable time.
