This is definitely cloaking. I wouldn't do it if you are not absolute certain about how fast you can throw away a domain and setup a new one.

If you want to cloak as a profession, I think it's the same amount of work as getting to the top without cloaking.

And cancel any contracts with ISPs :)

> Please explain.

Simple. A browser/bot sees the view.php?string and follows it. The script behind this address will invariably point the browser/bot to the new location. In other words, everyone sees it (otherwise, your browser wouldn't be able to follow it).

The browser and the bot are different, aren't they? The script only points to the URL (in the text file) when it's actually executed. Obviously this opens the new page in a browser, but does the bot do the same? Does it cause the php script to be executed?

And if I deny the bot access to the text file (with a robots.txt file), surely there's even less chance of PR being passed on.

Yes, of course. I said it in my post. But if you look more carefully, depending on how well written is the script, a manual chect is needed to find it.
If you make a list of browsers, something like:
MS IE, Netscape, Opera, Mozilla (that's an example). The you retrieve the visitors software name through a php function (I don't remember the name), and check if it's in this list. If not, you set the bot variable to true. Then the link will only appear if one of those browsers is detected. Unless bots report themselves as one of these browsers (that would be even worse than cloaking) or a manual chek is made using one of these browsers, the link will not be seen by google.
Illusionist wanted a link for users that should be not followed by bots... Illusionist needs cloaking. Of course, this is cloacking. I don't like to use these techniques, but I know how they work. This is a possible answer to Illusionist's question. I'm sure that nobody will be able to give any answer that is not cloacking.
I'm not defending these methods, simply exposing how they work.

I don't really know whether hiding the address makes a difference.

Look at yahoo: They link to

[srd.yahoo.com...]

Which in turn is a 302 to the real URL. And it passes PR.

The main question (at least for me) is whether it would make any difference to encrypt the URL, like
[srd.yahoo.com...]

Technically it doesn't make a real difference, every bot can read 302s.

I'm no professional cloaker, but I wouldn't rely on UA for that. This can be faked and automated from the GooglePlex.

Look, despite the confusion surrounding Google's serps, and the true value of content in the current algo.

If you think your visitors need to see it, then bl*ody well link to it - I'm amazed that so much effort has been put into your *problem*, and equally amazed that you're still irritated by not getting an answer.

This is a webmaster forum, not a spam support forum.

If it is worth linking to, damn well go ahead and link to it.

Plus, Google may actually be giving you positive points for outbound links... rather than "leaking PR", you may actually gain PR. Whether it is visible or not is another matter. But if you haven't noticed, the last update seems to be a strong inducement to add outbound links to other domains - visible to Googlebot.

Almost 2 years ago Googleguy coined the phrase "hoarding PR" - Google doesn't like this.
From [webmasterworld.com...]

"Of course, folks never know when we're going to adjust our scoring. It's pretty easy to spot domains that are hoarding PageRank; that can be just another factor in scoring. If you work really hard to boost your authority-like score while trying to minimize your hub-like score, that sets your site apart from most domains. Just something to bear in mind.. "

GG also said ...
"You can try all sorts of stuff to "conserve PageRank," but that's no guarantee that something will work, or that it will work in the future. I think Giacomo's advice was the best of all: "Stop watching that green line on the toolbar, and try to focus on your site's content." If you spend your time making a great site that attracts and keeps users, the rankings in Google will follow. Time spent improving and adding content to your site is maybe the best payoff."

Don't hoard your PR... share it and you will be rewarded.

It's kind of funny... Google now seems to be rewarding "hub" sites, over "authority" sites...

Completely agree. Also, if you use the php I suggested before, G won't like it.
But if you're desperate, why have you put an outbound link in your homepage? Cannot it be put on your links page?
You could also try to use frames or iframes.
Maybe it has changed, but I've never heard about PR leaking through frames. I had to put alternate code in my framed page to let PR reach all files, for example.
If the link is some kind of advertising, you could also use a popup and let the client's software block it ;)
But I think the best idea is to have a links page for all outbound links. Note: the links page can be a file or a lot of files, dirs, etc, depending on your site's size.
Another solution is to put a lot of links in your homepage to files that link back to home and have no more links. For example: last 20 articles published. Each file should contain the article and links to the homepage at top and bottom. Then the PR passed through the outbound link will be less. As more links in a file, less PR passed through each link ;)

Greetings,

PS: Of course, the best way to get a lot of links in the homepage is somethink like last articles, last posts, most sold widgets, or any kind of ranking. And to keep them fresh, use php, asp, or any server-side scripting. You can use even Java.

"Stop watching that green line on the toolbar, and try to focus on your site's content."

Why not do both? They aren't mutually exclusive, and Google invented PR and the green bar, so what do they expect?

This might be slightly off topic but possibley a potential solution...

Does Google index/spider ISO-8859-1 (Latin-1) character set within your html code?

I wanted to know for another reason but it struck me this could be an answer to PR black holes- a legitmate problem I think.

Although I do fully agree with DVDBurning sentiments too..."Google may actually be giving you positive points for outbound links"

Whether this is on topic or not I would really appreciate if anyone can give me an answer to the question above rather than starting a new thread.

Thanks

Why should Google ignore 'foreign' language sets?

I don't see them following "SUBMIT" buttons yet.

Create an <form action="http://www.domain.com"><input type="image" name="submit image" src="click_here.gif"></form>

I don't really see the need but it would be an option.

I know I'm not likely to get a definitive answer on this, but would a 302 redirect script of the following general form pass PR?

http*//www.domain.com/redirect.php?a=1&b=2&c=3&d=http%3A%2F%2Fwww.otherdomain.com&e=

The consensus is that the yahoo 302 links do pass PR, but they have an unencoded URL and only 3 variables:

http*//srd.yahoo.com/S=41170016:D1/CS=41170016/SS=41170018/*http://www.domain.com/

I guess the bigger question is whether the actual URL needs to be contained in the link, or if PR is passed by any header redirect regardless of the href.

Many thanks indeed for this suggestion :-)

Hi dorjesempa,
Try this:
<a href="#" onClick="window.open('http://www.domain.com','_blank');return false;">text link</a>

Best regards, Arno
