Subject: Is PageRank Finite?
I am wondering is PR is finite? Websites that do not do link building
and obtain backlinks in a natural organic way often have very few
incoming links which means lower pagerank.

I have a few blogs in the renewable energy area where I find, review
and write about companies, people and technology I believe will
encourage the growth of alternative energy.

I am generous and link out to others but sinse the site is new and
relatively unknown I am not yet getting many links to bring in more
pagerank. In other words I am giving more PR out than I am getting.

The question:

I recently started using the nofollow tag on external links with the
belief that pagerank is finite and I only have so much to share. Am I
shooting myself or those that I link to in the foot? Is this an
incorrect assessment of how to pass PR?

I believe this to be a highly relevant question and example of why
nofollow tag needs even further explanation.

Thank you if you feel comfortable with answering this Adam Lasnik or
others...

Aaron

Aaron, you shoot yourself in both feet. PageRank hoarding is a sin. PR
is a sexy fay you should not pass, that's way to rough. Let her flood
your site, let her come and go as she decides, don't even think of her
when you deploy links. And please remove the f** nofollow values in
your rel attributes, that's unethical and counter productive.
Really :)

So if I have a new blog with pretty much no PR is makes sense to link
out to all my friends? I don't know Sebastian, in an ideal search
engine world that would be great but I am not so sure pagerank in
infinite. I have also been thinking the way you do for a long time but
now I am not so sure man.

The way I have been using the nofollow is if I write about a grat
subject on another site but that site is filled with paid links I use
the nofollow because I do not want to pass PR to a bunch of spam sites
selling links BUT this recent idea is driving me nuts. ;-(

Subject: Re: Is PageRank Finite?
Aaron you bring up a good point.  A while back when some sort of
penalty was being dolled out Adam repeatedly said here and other
forums that one factor may be "Over Optimization."  To me a site that
has all external links nofollowed is ripe to be picked in an
algorithim for over optimizations because of the un-naturalness of
it.  It's a strong signal of two things 1) this guy doesn't trust
anyone he's linking to or 2) this guy is trying to hoard page rank.
Neither is a signal that should help a site rank for anything.

Back in the day search engines ranked based on the text only, keyword
counts etc.  People started repeating "free porn" 900 times on a page,
then they started looking at the META data people started stuffing
them, links were good so people started selling them, in all cases
google reacted and penalized the offending sites.  Nofollow was
introduced as a tool to help eliminate the value that blog comments,
message boards, forums, etc where having on the ranking of sites.  If
you're the site owner and didn't write the content you have a way of
saying I cannot vouch for what's there.  I would bet that if someone
tries to turn that around and use it to IMPROVE their page rank,
they'll get busted.  Just as using your keywords in sentences is good
but repeating them 100 times and abusing the H tags is bad.

Another thing to consider is from the inherent nature of the "web"
sites are not meant to be islands but rather connected to the whole
internet by both incoming and outgoing links.  A site is judged not
only by the content and anchor text of incoming links but the topical
nature of the sites linking in and the topical sites that you link
to.  If you have all nofollow links you are missing a key ingredient
to telling Google what the site is about.

I don't have any insider knowledge, but given enough time patterns
will emerge in the mass of data that they pour over every day, and I
wouldn't doubt a signal they will look at is your linking habbits and
the use/abuse of the nofollow tag.  PR hoarders will be penalized as
its a breakdown in the natural flow of the web.  It's like the wiki
debate, if they don't trust any of their resources then they shouldnt
be trusted as one themselves.  Of course they've got enough momentum
that their probably impervious to any sort of algo change, but smaller
sites are.

So where is the line between SEO and SEOO (search engine over-
optimization)?  I'm not sure, but as Adam also says, "does it pass the
smell test?"  And saying, "I changed all my links to nofollow so I
don't leak page rank" smells like you are trying to game the system
and artificially influence googles ranking, which in  my experience
they frown upon and react.

Personally, I always have nofollow links highlighted in my browser
with a bright red box.  If I stumble upon a site that has too many, I
move on, I wouldn't doubt google takes that stance sometime in the
future.  I just don't trust the nofollow actions yet, and I think its
going to get worse.  If you really want a bunch of sites that you link
to be not followed for ranking purposes (affiliate links, selling
links for traffic only, etc) I'd put those on a redirection hidden
behind the robots.txt.  That way Google isn't going to follow them at
all because they aren't going to see them, and they are not going to
be able to hold it against you because there is no possible good that
can come from a page that is not crawlable.  As far as a site with no
eternal links, I'd say that's just as shady as disabling the back
button, the site is no longer a part of the web, but only a town where
all the streets going to it are one way, and after a while people will
notice that no one returns from that town, and no one will go there
anymore.

Now I doubt Adam will/can come on here and say that they penalize or
don't penalize or give credit for the use of nofollow as commenting on
the actual ranking is probably not allowed in the least bit, but these
are my two cents :)

In the case of linking to a site plastered with affiliate links and
ads, where is the point to write about them in the first place, if you
don't like them? Well, given that this site has a page hosting
valuable information, wouldn't it be the search engine's job to allow
or disallow incoming PageRank at this site? Why should you pre-qualify
links for Google's ranking algo? This attitude smells like self-
censorship based on fear, and you shouldn't fear Google when you link
out.

Applying nofollow crap to affiliate links is a completely other story.
I have no problem with Google's position that affiliate links should
not carry Googlejuice, but just the human traffic. I say "nofollow
crap" because rel=nofollow is IMHO not the suitable instrument to
achieve this particular effect, or call it favour to the engines. I
use rel=nofollow with affiliate links to save my own ass, although
it's Google's job to decide whether a particuilar link should carry
weight or not, and although I do think that rel=nofollow is not the
right thing to use in this case.

All this thoughts and countless confused discussions are results of
the somewhat hapless implementation of this crawler directive, and
it's ongoing semantic morphing. Sure, rel=nofollow is a generic
mechanism to do a ton of things which all make sense. But it's a geeky
tool for search geeks, not a suitable tool for webmasters, editors, or
publishers.

Ok, back to PageRank. Think of PR as a statistical approach to emulate
Joe A. Surfer's behaviour, where the middel initial stands for
Average. PR just tries to follow Joe's footsteps on the Web, sometimes
guessing whether Joe will click link A or B, thus deducting both
possible click-paths' scores equally. PR is a model of the Web, kinda
road map from any point to any point, weighting each and every path/
lane's quality by scoring the destination. And because it's just a
model, it's weight as ranking factor is not that important as the
toolbar suggests. The PR hysteria reminds me of the Beatles BTW. Sure
PR is great, it's sexy and all that, but it doesn't show the (whole)
big picture one has to think of when it comes to optimizing contents.
Hence optimize for visitors, remember the visitors pull out the
plastic, not the bots, create broad and easy to walk paths through
your contents all leading to your signup forms. PR will follow the
visitors to honor your efforts not only with green pixels. IOW since
todays PR is Google's secret sauce, and there are other important link
cargos, it just makes not much sense to speculate about PR
distribution. PR is addicting and distracting, hence you should ignore
it to get your job done.

I agree with a lot of what you guys say but let me ask a few more
questions:

JLH - If Google punishes sites that hord PR why does Wikipedia
(educational), Amazon (affiliate) and other eCommerce sites doing so
well in search engines?

If you look at http://solar.rain-barrel.net and any other of my sites
you will see that I am doing nothing to game search engines at all but
also notice the PR, how much do I have to share? >> Is PR finite? <<

Sebastian - You said" "In the case of linking to a site plastered with
affiliate links and
ads, where is the point to write about them in the first place, if you
don't like them?"

Say I find a farmer/inventor who doesn't have a website but his new
wind turbine was written about on a local news site that is littered
with paid links and it's "SEO" is linking out with hidden text to
viagra spam. I want to write about this man who is offering something
unique but the only reference I can find is on this local spammy news
site. Wouldn't this be a case when the nofollow tag should be used?

Here is another one: Say I write about a cool company that is looking
to market complete solar arrays but when I review the company I find
that they have multiple sites and I just do not have time to analyse
their intent, wouldn't it be safer to use a nofollow here?

I do not spam or use the nofollow to spam BUT if I understand it
correctly what it does is break the connection between you and the
possible bad neighborhoods that can have indirect negative impact on a
websites "trust" or whatever you want to call it.

One more thought: Did you guys ever think that our debates actually
build better algorithms? Are there people in white coats with clip
boards taking notes? You guys got all kind of interesting ideas,
that's fo' sho', thanks! :)

If you link to linkworthy content you should not use rel=nofollow. If
Google doesn't think the linked site is worth indexing, that's fine,
but it's not your problem. You've done your job by providing your
visitors with external content you honestly think is interesting for
the crowd. Trying to guess what Google could think with the intention
to castrate a link when Google might dislike the target sounds just
not right, and it makes no sense, and Google doesn't encourage you to
handle rel=nofollow this way. This goes for both of your examples.

Also, not every site carring tons of ads is a bad neighborhood, think
of high ranked sites like SEW for example.

Would you link to my articles (I know you did it already)? Oups, I
should have told you that Google (AdSense) pays my hosting fees ...
sounds weird, eh?

Subject: Re: Is PageRank Finite?
Great discussion so far, probably since we are all just throwing out
ideas and no one has taken a stance, so I'll continue best I can.

I'm not sure if they do or would punish or even consider the use of
nofollow in a sites ranking but for the examples, wiki, amazon, ebay,
etc the hard part in that they already have a ton of momentum as far
as traffic, links etc that they would be unharmed by such a filter.  I
think were you'd see it is average joes site with 18 incoming links
and 125 pages in the index.

Back to the finite PR discussion.  I'm trying to get my head around
what the question is.  Are we concerned that give a pages actual (not
toolbar) page rank that it only has so much PR that can go around? So
if you've got a page with PR5 and you have 3 external links do those
links receive 1/3 of your linking power, or if you've got 100 links do
they see 1/100th of the linking power?  From what I understand the
actual PR of page is just related to the incoming links and has
nothing to do with on-page or linking habits.  A page with 100
external links and a given X incoming links will achieve the same PR
of a blank page with no text and not links receiving the same quantity/
quality of X incoming links.

Now the question becomes is using nofollow on a link reduce that drain
on the linking power of the page.  If the above is true and our page
with 100 links were passing 1/100th of its linking power to each page,
if we changed half of them to no follow would the remaining get 1/50th
of the linking power and all 100 get the traffic flow? I'm not sure
its as straight forward as that.  As PR passing has as much to do with
being on topic as the actual PR of the page.   We've all seen sites
that cannot even get indexed when they say that they've got hundreds
of links, well further inspection shows that they are all junk links,
exchanged directories, off-topic etc.  This has got to have the same
effect on the linking page.  Given the same page with 100 links and 50
of them are off topic does the page not pass PR which also means that
it doesn't drain the PR passing to the other links or does the
opposite happen where it actually costs you since you choose to link
to bad neighborhood or an off-topic arena?

My theory is that they currently just treat a nofollow link as an
"ignore function" such the link is no longer a valid link, even though
it appears to be to the general public.  Google doesn't even appear to
crawl said links, on the other hand Yahoo will crawl them for darn
sure, I do not know if they consider the link in their ranking as I
don't spend much time analysing what some 3rd rate search engine does,
other than send terribly targeted visitors.

My cynicisim on nofollow also comes from the evolution of it.
Originally introduced to try to reduce comment spam, which it didn't,
now has evolved into protecting links for money etc.  I find it
strange that they got all the CMS out there to institute in for
automatic use on blog comments for example, but there is no discussion
on removing it.  If I write a blog post and 50 people comment on that
efficitivly writing my content for me, some of those comments will
probably contain good links that are germane to the conversation and
should not be nofollow any more as they can only help my page rank for
its rightful terms.  But there is no mention of that at all.

I've taken it upon myself to institute a nofollow policy on my own
blog which I publish, its fluid and may change with time, but the key
component of it right now is that I've used a plugin to make nofollow
comment links turn to real links in 14 days.  It gives me two weeks to
judge each comment and if I see a link I don't like I'll break it,
otherwise I let it mature and become a normal link that ads to the
page and discussion.  I'm not so sure that my policy is in line with
googles ideal, but until they give further directions its the route I
want to go.

The blanket statement that all links that are paid for does trouble me
a bit, based on history more than statements by such pundits like Matt
Cutts.  I agree in principle with what he says in that you shouldn't
be able to influence the search engine results because you went out
and bought 500 links from probloggers out there, but then again they
don't have a problem with yahoos $299 review fee do they?  Based on
the fact that yahoo doesn't guarantee inclusion.  Well if I'm the
expert on solar energy and you want me to write an article about your
service that may or not may contain a link to your site, who's to say
that I didn't receive 25 other offers from other solar energy sites
that I declined.  In which case I think a nofollow is an
misapplication of the tag.  Sponsorships are a part of this society
and I don't think it can be controlled with a policy like this.
Should the US government require a blanket statement after every
product endorsement on TV, a warning label that says Tiger is paid by
Nike to use their golf balls so please don't accept his endorsement
because of that?  No we leave it up to the general public to make
their own decisions.  Well in the case of a paid review/posting the
endorser is the writer and the general public is google.  Their job is
to consider the source and consider the subject and decide if the
endosement carries any weight.  Just as I'd rather take my golf ball
advice from Tiger than Al Gore, Google should consider a paid review
on Solar Energy by one of the leading experts in the field more
important than my sisters "I love Cats" blog.  They are asking us to
do their job judging links and pages, which just of course lends
itself to even more manipulation than it was originally instituted to
contend with.

Speaking of which we should really take this somewhere where someone
is at least getting credit for the writing, as I'm not getting any
link love or clicks on the ads to the right of this post!

Well, to be safe I do not do anything online that is "paid" other than
reviewing a few products to pay my hosting fee using amazon.com
iframes and google adsense that monetize a few dallors a day. I got a
couple directories that scare people away with their high price and
extremely strict guidelines (note, know of any good sites? submissions
are free, shhh)

Great points, but one question about the Yahoo! directory, people keep
using it as an example and I am not so sure it is passing link love at
all. In fact, any directory that is paid would be violating Google's
guidelines correct?

Anyone know of a way or tool that shows if a "paid" directory is
passing pagerank? This would be a good way to determine is Google is
treating everyone equal which is another accusation I often read on
blogs.

Also, how about Google just update the guidelines to show proper uses
of the nofollow tag?

Just a few more ideas...

I'm not sure on the yahoo directory as I'm not paying diddly doo for
anyone to review my site, but Google still references it by name in
their guidelines.

"Submit your site to relevant directories such as the Open Directory
Project and Yahoo!, as well as to other industry-specific expert
sites."

http://www.google.com/support/webmasters/bin/answer.py?answer=35769

Whether thats the free stuff or the paid one I don't know.  And don't
get me started on that scam of the ODP, anything that claims openness
needs to have transparency and they have none.  If you submit a site
for inclussion and it gets shelved because the editor is your
competitor that should be made public so the reasons a site wasn't
included.

I'd suppose John Softplus has some experimental data to back up yahoos
linking power.

The official Google policy on buying links seems to be it is fine as
long as you are buying links for traffic and not for PR or ranking
purposes. Now how they can determine intent is debatable. Some sites
make it clear that they are selling links for the purpose of PR but
there are many sites who do not mention it at all but you have to know
most of the people who have bought links did it to improve their SE
ranking and PR score.

I stumbled upon an interesting item, I wonder if it's related to this
subject.

http://www.google.com/support/webmasters/bin/answer.py?answer=34397&c...

Most notably:

Although Google crawls billions of pages, it's inevitable that some
sites will be missed. When our spiders miss a site, it's frequently
for one of the following reasons:

    * The site isn't well connected through multiple links to other
sites on the web.
    * The site launched after Google's most recent crawl was
completed.
    * The design of the site makes it difficult for Google to
effectively crawl its content.
    * The site was temporarily unavailable when we tried to crawl it
or we received an error when we tried to crawl it. You can use Google
webmaster tools to see if we received errors when trying to crawl your
site.

I'm looking at the first one in particular, where they seem to
insinuate that your site may not be included in the index if doesn't
include "multiple links to other sites"  Would NOFOLLOW on all
external links constitute this?

Also, note to Google Editiors:  The second one seems a bit dated as
Google no longer runs one big crawl and a general new index push
anymore as its continous. So if you want to fix that up and give me a
link on your homepage that would be great.

Subject: Re: Is PageRank Finite?
Forgot to add:

You cannot lose PageRank by linking out. Google gives you PR with the
duty to spread it. With every new link on a page you lower the portion
of PR it sends to its link destinations, but all the PR you've earned
from your inbounds is assigned to your pages. PR is somewhat sticky.
This goes for internal links as well as external links. The only way
to lower a page's PR is to lower the PR of at least one page linking
to it. Well, Google can nullify PR, but that's done with the worst
offenders only, and it can spoil down the ability of a page to
bequeath PR, what you mostly don't spot because it's PR doesn't
change.

PR hoarding is creating a black hole, like Wikipedia did recently.
Such a black hole sucks PR, but distributes PR to own pages only. BTW
Wikipedia has asked Google for the permission to become a black hole
before they nofollowed all external links, so they have got some
special treatment with regard to PR hoarding "penalties". Since
Wikipedia links didn't carry much weight before IMO, this black hole
should affect only pages living off from Wikipedia inbounds.

Agreed on ranking, PR is less of an influence, but keeping your site
crawled on a regular basis has everything to do with PR, which is my
only concern.  And if you ever try to launch a new site, having a
little PR to start the crawling doesn't hurt either.

OK, time to debunk some PR myths.

John, add a dampening factor and a few gimmicks to your post and
you're spot on.

{Aaarrrggg ... Googlegroups has stolen my cursor again}

PR has absolutely nothing to do with relevancy, so unrelated or off
topic links carry the same PR as  on topic links.

{Google I want my cursor back!}

Google encouraging YAHOO paid as well as unpaid listings has not that
much to do with the payment itself, but with the editorial character
of the directory. So Y! links are treated exactly the same way as DMOZ
links. BTW you may have spotted that some ODP categories aren't
bothered with PR, these links don't pass PR, probably because the
editors are your competitors.

{Google return my cursor or I reveal that you've scanned the brains of
all ODP editors to figure out who's linking
honestly and who does not!}

Crawling schedules are more or less completely driven by PageRank.
High PR values result in frequent crawls, low PR makes Ms. Googlebot
lazy. Laying out milk and cookies attracts and holds Ms. Googlebot,
she loves cookies.There are other factors like freshness and source
scores involved when it comes to fetching brand new stuff.

{Nasty Google, I do miss my cursor ... pleeeaaase! }

"Page" in PageRank stands for Larry Page, not Web page.

The PR of the whole Web is 1, not 42.

Sebastian out to hunt for a new cursor

LOL, thanks for all the info. today but I must say, none of us still
know for sure if PageRank is finite and can be used up like fuel. :)

Definitively finite, PR cannot leave the Web.

The law of conservation of then PR applies? Page Rank can neither be
created nor destroyed.  So PR is more like energy which is just
converted and transfered than like currency which can be produced,
spent, wasted?

So who's going to mirror this discussion in their blog so that we can
link to it? :-)

Great stuff, guys.

Is pagerank diluted as you add more content to your website?
Is pagerank diluted as Google adds more filetypes to the index?
Can issues with numerical accuracy result in "chaotic" pagerank
fluctuations?

All webpage's PageRanks add up to 1. And of course, PageRank can't be
a negative number.

So yeah, PageRank is a single pie, just sliced differently as new
pages/links get added to the web every day.
