When do you get the PR and backlinks boost?

when it's calculated or when google spiders the pages that link to you?

[walkman]

I know the PR changes every six weeks or so on the toolbar, and the same goes for the backlinks, but, does Google boost your site on the SERPS before that or it waits for the big calculation?

I'm curious.

Me too!

Well they are both simultaneous in a sense .. but SERPS can change almost daily .. whatever trend it picks will decide your PR trend as well.

[walkman]

so when Google visits the high PR /multi-page site that linked you, you will get a boost, even though the PR on the toolbar and backlinks are the same?

The primary immediate benefit is the link itself, because then we can find the page, rather than some really fast boost in PageRank.

Hi GoogleGuy,
I understand that but the site is already found.

walkman, it happens almost instantly you're included. We've got a new page with just one link to it from a PR5 page. That new page was picked up by Google last week, it obviously has a PR of 0 but it now comes in at #1 (out of 42,200) in SERPS for it's relevant keyword.

"it happens almost instantly you're included"
if it's this easy to calculate it on the fly, then why not change the PR on the toolbar too?

I'm not knocking down your observation, I'm just asking.

That's not something you should ask me, ask Google :-)

All I know is what happens on our site when we post a new page. Google may have many valid reasons for not updating the toolbar.

"then why not change the PR on the toolbar too?"

Calculating on the fly the effect of ONE link is pretty easy. WE can even do it. Look at the PR of the page the link is on, look at the number of links, guestimate the PR. What is not so easy to do on the fly is calculate the effect of dozens or hundreds of links. Seeing one link for a PR5 page could make Google guestimate PR4, but if there are one hundred similar links, the page wil be PR5. Better not to guess than to guestimate based on incomplete data.
