Backlinks to homepage or any other page ? Does it matter ? I have so many to homepage but i don't have any to other pages. If i get a backlink to some of my other pages will my website still have the full benefit of that link?
If you have a lot of backlinks to only your homepage, than most probably your homepage has a nice PR and the rest of your pages are 0. Deeplinks help your inner pages have higher ranking, and also in establishing so called Google site links that are listed under your domain in the search listings. Good Luck
I disagree macadu You can still get inner PR without linking to them, depending on the authority of the homepage For example, I only built links to the homepage of my blog but have like 10 PR inner pages However, it is still a good think to do deep linking
Yes, it's a good idea to increase the number of your internal links. You'll increase, this way, their importance and the possibility to be visited by yours visitors. Internal link architecture is important for a site's SEO potential. Here is a interesting video: http://fr.youtube.com/watch?v=26_hNwDkE8A
