Thought i would share this chart with all of you.

It allows you to estimate how many back-links you need from a certain PR domain to achieve a certain Page-Rank

I found this was very helpful since google has not updated any of my back links and i have about 22 PR7 & 8 back-links and most page-rank prediction tools out there will show your future PR 0 until google updates your links.

Well this is actually using Google PageRank equation
PRA = 1-d + d*( PRs1/Cs1 + PRs2/Cs2 + PRs3/Cs3 + ... + PRsn/Csn)

There are other factors of course.. No this is not my chart but these same results are found through out the internet. Most all the PR predection tools use the same Formula. However for example my site I cannot use any of them since many require that your backlinks be indexed allready, even tho i have many high PR backlinks. This is a faster selution for those not willing to wait.

You can find these calulators all over the net
here is one such tool that uses the same formula as above

thanks Richard...
now i can understand the Google PageRank equation.
one question :
is the PR depend on outbound links?

Im not sure i understand the question.

You gain PR by the number of Inbound links to your site "links such as your signature" links from another domain pointing to yours.

Outbound links will generally cause your PR to go down as your page-rank trickles down into the outbound link domain..

1 thing that it very important as i have found out is to make sure that pages in your site are linked together.

meaning every page of yours should contain a link to ALL pages on your site
Google doesn't like dead end pages.

What can happen is if there not all properly linked together you will notice your main page will go from say PR0 to 3 but all other pages will remain 0

This hapend to me on one of my domains. I only had 3 pages all linked in the navigation header and they went from PR0 to 3 but the pages that were just
linked from my homepage to the page with no link back to home as well as the other pages remained a PR0.

I later read an article explaining this to me but it was to late lol

Heres the equation a little more in depth

The PageRank equation is simple:

PRA = 1-d + d*( PRs1/Cs1 + PRs2/Cs2 + PRs3/Cs3 + ... + PRsn/Csn)

Where

* PRA - Pagerank of a page A
* PRsi - Pagerank of page si which links to A; i ranges from 0 to n, n is the total number of all incoming links. The linking page may be any page in internet in any domain.

* Csi - Number of outbound links on page si, which has given the link.
* d - Damping factor whose value is between 0 and 1. Usually 0.85

To answer your question digital-media nobody knows exacly.

Im in the same boat as u.

I have a newer domain that has over 50 very high back-links from
pagerank 8/7/6/5/4/3/2 domains and google has yet to show a single 1.

Although other SE such as Altavista and yahoo are slowly adding them every day.

google generally updates there BL every 3 weeks or so.
heres a site that keeps track of when specific updates have hapend in the past

That original data was put together by Bob (Compar) a few years back. Since then lots of peeps have copied it etc.

With regard Google showing backlinks, don't worry. google shows a selection of backlinks and never all of them (unless you have like 1 link and it displays 1

If you want to know if you are getting link juice then go to the page carrying the link, see if your link is in the google cached version of that page, and if it is you are, if it isn't you're not

The only unknown is whether or not Google passes any, all, or a reduced amount of link jusice from pages in the Supplemental index!

More than these factors involved in PR calculation
eg:outbound links
This calculation based on less than 40 links on the page.
if more ,PR less
if only 1outbound link in page.
2-3 PR7 will transfer PR7 to your site ,not 15!

This is a wonderful set of information. Thanks very much indeed for it.

Just a couple of qustions for you pr calculator experts.

How much does it matter, if your inbound links are reciprocal?
Does this have no effect, some effect, or a lot

How much does it matter if your inbound links are not relevant?

These answerss would determine my linking strategy.

You (and many along with you) are comparing apples and oranges. How you link does not affect your PR as much as it affects your rankings in the SERP's.

Google have now admitted to having almost 200 elements to their algorithm (double from what they admitted less than 2 years ago). Within the algorithm playing a very small part is Page rank. PageRank however is different from links, which play a MASSIVE part in the ranking algo and are one of if not THE most important element (indirectly again as it is the anchor text element of the link that palys a larger part than the link iteself per se')


For PR it matters slightly but only because PR is a two run system where the value of a page you link to is added to their PR but also the reciprocal link adds value to your PR value. This is only a 2 way system though not an ever increasing round of compounding PageRank.

For ranking in the SERP's it is now widely accepted that reciprocal linking is being devalued over time and will be devalued further in the future.


For PR, not at all as PR is PURELY a numeric calculation and does not include text based arguments.


For Ranking again it is a different story. Google is moving towards a semantic algorithm more and more. the relevance of the link anchor text (as I aluded earlier) and the content of the page carries a lot of weight, and is likely to carry more in the future..

I hope this has helped you understand it a little better, but please don't get too hung up on PR it really is not THAT important unless you are buying or selling it

People often take part in three way link exchanges now, as google doesn't like link exchanges.
