PR6 backlink site doesn't show up

Why?

Why doesn't a link from a PR6 site show up in the Google backward links?

This thread is pretty much the same subject as your ongoing thread, http://www.webmasterworld.com/forum3/8513.htm [webmasterworld.com].

Yes, but this question has not been addressed. Only the 2nd question is being addressed, so I thought I would start a thread for it. :)

OK, let's give the general question a general list:

1. Because the link is too new.

2. Because Google can't follow the link.

3. Because the page it links to is less than PR4.

4. Because it's not really PR6 but the Toolbar shows PR6.

Any more reasons why a PR6 backlink doesn't show?

If the page linked from has a 'can inherit PR but not pass it on' penalty, then I think the backlink shows (even though no PR is transferred).

If the page linked too has a penalty, does the link show? (reason number 5 if not)

Ciml,

What is a 'can inherit PR but not pass it on' penalty?

Thx

[ciml]

The 'can inherit PR but not pass it on' penalty was used for guestbooks for a while early last year.

Pages that featured the word 'guestbook' or 'guest book' to some extent did show PageRank on the Toolbar and ranked as though they had that PageRank; but they were not transferring PageRank to other pages. The guestbook category on DMoz.org and directory.google.com were both affected.

I seem to remember the same thing happened with Web promotion categories on dmoz.org (this was thought to be to do with linking to a bunch of PR0 domains).

5. Because google tells us that they don't show all the backlinks. They never told us which ones they do not show, or how they decide which ones to show. It is quite probable that there is more involved in this than toolbar PR.

3. Because the page it links to is less than PR4.

So any page with a PR of less than 4 will not show backlinks?

Can anyone disprove this?
