i am wondering about pages which do not have page rand is this mean that google spiders do not reach it note in google results i can see some pages do not have page rank so this mean that spiders can reach there pages waiting for you explanation
Pr has nothing to do with whether spiders reach pages or not. Pr is given to a page according to backlinks to it. i.e your hompage will probably have a page rank because there are backlinks to it. whereas the internal pages don't have so many backlinks or maybe none at all. Second level pages often get a PR because it is passed down from the homepage through links to the second level pages. i.e pages from your website menu.
every page reached by google spiders has back links because spider always reach the page by aack link right so why they do not have page rand even zero page rank ??
i've designed a website for a rent a car company from my country that has 4-5 backlinks i think and it has PR 3.
i am not talking about my site but about millions of pages and you can see thousands of them in digital point
some reasons for sites with no PR: newly built site no backlinks sites that didn't catch-up on PR update
not all pages get PR - but i do find it odd that pages for some sites like bank sites and what not where there are password protected pages with PR - who is linking to my personal bank pages????
That's pagerank from your homepage passed down to other pages. That's why you might wana rel no follow those links that are not important like about us, contact etc
