I recently read this seo book, and it said that link juice can be passed via pages through you website. Just say your Home Page was PR5 and you had a link to another page on your site, link juice is passed? But i thought considering the pages are on the same IP no link juice will be passed? Cheers.
Yes they can help you and if you know some deep knowledge on keywords than you can make your inners pages also rank well .
Pagerank is distributed to internal links. Probably not as much as to external links though, because it's a vote for yourself.
As few others said, dofollow internal links will pass link juice to your inner pages. By the way, internal linking is good for especially Yahoo search, though it will not exist after some months if everything goes well
Yes, internal linking will pass on link juice within your site, probably not as much as an external link of equal value, but its definitly valuable.
Page Rank sculpting using rel="nofollow" is a thing of the past. But Page Rank sculpting is not. There are other ways to decide where Page Rank is passed on your site. Using JavaScript, for instance, to link to pages you don't want to pass PR to still works. By being more selective about which pages you link to in your header, footer, and content you can also still scupt PR. For example people might have previously linked to contact us, about us, privacy policy, terms and conditions, disclosures, etc. on every page on the site because they could simply rel="nofollow" the links. Now maybe they have a single link on every page to a single page that contains all of those links or two links on each page - one to a page with all legal links and another to a page with all info about the company. This is still page rank sculpting only using different techniques than the rel="nofollow" attribute. You should be selective about which pages link to which pages on your site, and have a strong information architecture. This can maximize the "juice" passed to your most important pages.
This is slightly off-topic, but I always tell my clients not to block contact, legal, or about pages. Usually if they're re-written to provide useful content the search engines (and other users) may ironically find them useful. (Believe it or not, I actually find links to those types of pages being posted as examples of how -- or how not to -- write such pages). In other words, if I don't want a page having PageRank or weight passed to it, I do one of two things: rel="nofollow" followed by meta "noindex nofollow" and a block in the robots.txt file, or (better yet IMHO) don't put it on the Web site to begin with.
