Always we have question that Home page have the Page Rank 5 or 6 but the links pages with 0. The above question asks whether you should deem linking to a PR 5 site when the links page is a PR 0.

Reason 1 – The links page is newly added and has not had a PR assigned to it in the Google toolbar.

Reason 2 – Links page is not being linked to, or is linked to using a dynamic link.

Reason 3 – links page is hidden deep in the navigation of the website. Some webmasters bury the link to their links page deep within their site, so that the only way a search engine spider will discover the links page is by following 3 or 4 links from the homepage. When this is done, very little (if any) PR flows to the links page.

Reason 4 – Multiple links pages conceal the page your link is found on.

Reason 5 – Check for a robots.txt file on the site which is requesting the link exchange. If there is one, make sure that there is no control that disallows the spiders from accessing the links page. This is a technique that will avert the search engines spiders from visiting the links page, so no PR, and no advantage, is passed to your site.
