Does this link pass link juice: http://www.finda.co.nz/redirect.php?listing_id=r2vp&url=http://www.avantifinance.co.nz

Hi Barry,
As I said in my response, I used tools to check for the headers returned by the URL, the same information that is returned to search engine spiders.
There no way to know how the PHP script is made, for me, or for a search engine spider, as the PHP is executed server side and all you get back are the HTTP headers and content.
The url doesn't contain any id, it's simply the redirection url that is passed to it so the script probably look like this :
header('Location: '.$_GET['url'], true, 301);
?>If the redirect.php file was receiving an ID instead of a direct URL, it would probably look more like this :
// stuff to connect to the database here
include('connect.php');
//a long line not well constructed that does a lot of stuff
$url = current(mysql_fetch_assoc(mysql_query("SELECT url FROM urls WHERE id=".(int)$_GET['id'])));
//redirect to the URL from the database
header('Location: '.$url, true, 301);
?>It could be a way to trick user into thinking that the link is passing juice by doing a 301 redirect but blocking the file using robots.txt wich is not the case, there's also no Set-Cookie.
It is more likely to be a way to get statistics about what are the most popular links. For example, redirect.php probably add an entry to a database each time the url is reached to track the number of visitors sent to a particular website.
I hope my answer will help you understand the use of the redirect.php and the way it works. If you still have questions, do not hesitate to reply to my response.
Best regards,

I've been looking into this but don't have the technical chops to give you a definitive answer.
@Guillaume How can you say conclusively that it passes link juice when you don't know what redirect.php does? Unless you were able to see what it does.
For a straight php redirect to count as a 301 I believe it'd need to look like
header( "HTTP/1.1 301 Moved Permanently" );
header( "Location: http://www.new-url.com" );
?>However I assume that you can't do these sort of header redirects as you have multiple ids going into the same redirect.php file?
Do you put cookies on people before redirecting them (I assume there's some sort of affiliation reason to redirect this way)?
Without understanding how it works I'm not sure if it does or doesn't pass value, but please make sure you're happy with the information given to you.

Here in the learning session you find more information about the "amount" of link juice:
http://www.seomoz.org/learn-seo/redirection
A 301 Redirect is a permanent redirect which passes between 90-99% of link juice (ranking power) to the redirected page.

Hi Conradh,
The redirection is a 301 Moved Permanently, so it does pass link juice. You can find out using different tools like the followings :
http://www.seoconsultants.com/tools/headers
http://web-sniffer.net/
http://www.g-force.ca/referencement/entetesBut, to know if a link pass any link juice, there are also multiple things to check. First, check if the page is indexed in Google using site: or cache: command.
If the page is not indexed, it might be only a question of time, but it might also be because it is blocked by robots.txt, robots meta tag or by X-Robots-Tag.
Also, check if the link doesn't have the rel="nofollow" attribute. Any of those variable can prevent the juice to pass other than the type of redirection.
Best regards,
Guillaume Voyer.

Redirect from a previous url
Hi - newbie question I have a customer who's had previous versions of his website. Previously it was known as "princess-interiors.co.uk" (been around for a few years) and is now "princess-design.co.uk" (been around also for a few years). New site is WordPress - what would be the best way to redirect (I have access to the previous version of the site which is still hosted). I expect it's to use 301, but how would I do that (step by step), and does www. versus non-www need addressing (and how). Really concerned, as this site has gone to zero organic visits!! Hoping somebody can help. Thanks

Does a Soft 404 pass on link juice?
Hey guys, Just wondering if a Soft 404 passes on link juice? I know they technically show up as a broken backlink but since it takes them to the homepage, does the link juice get passed on or is it still considered dead and the link juice is lost?

301 redirect lost page authority & total links how ensure it passes on.
hello, I recently changed from www to non www. I have redirected my whole website so if I type www. it goes to the non-www page. doing a open site explorer I noticed my www. still has the page authority 14/100 with 6 links. where as the non-www page has 1/100 page authority and no links. how do I get the www. to mirror the non-www links?

eg if you goto http://www.finnmoto.com.au/mens-motorcycle-kevlar-hoodie/ it will goto the non-www version automatically, so why does the non-www replicate the page authority / total links attached picture for reference.
Google webmaster has been selected for non-www, its been about 2 weeks.
my domain authority i think about about 21 or more now its 19 aswell. I have a feeling:
nofollow or rel=canonical has something to do with it but Ill need read into what that does and how to apply. any ideas? uRiJ2Ul.png?10 -
Redirecting a penalized domain to a new one to remove penalty?
I've got this website that has been hit quite hard by the first Penguin update round. Would it be better to move all my content to another domain and do a 301 redirect? Or should I keep the penalized domain and try to clean up the bad link profile? Also I must say that the website has been hacked last fall and the hacker was able to upload porn stuff in one of the folders. Needless to say, I quickly acquired tons of links from porn and warez. And no, porn and warez has nothing to do with my website's topic. Thank you for your help! Stephane

Trying to avoid splitting Search Engine juice, need advice
We currently have a political issue with one microsite we're trying to promote. The group that created the website, created it without the consent of the rest of the company and now, although it's allowed to live, we've been given a few restrictions. They main restriction is that when the microsite is linked from the main corporate website it needs to be referenced as a subdomain so http://microsite.company.com. We've been promoting the site as http://www.microsite.com (I'd include the actual websites but don't want to air their dirty laundry). The problem is that a lot of the listings in google are starting to show up using the http://microsite.company.com url instead of the actual url we're about to start promoting and I'm sure that's going to split rankings. Is there a way to appease both sides here. Keep the subdomain from the main site but transfer the juice from that main link to the microsite url? To be clear, I can't just use a 301 redirect because that will change the url from the subdomain to the microsite url (unless i'm wrong) and corporate doesn't want that. Does any of this make sense? Any help would be greatly appreciated

Are old links worth more juice?
In the last week and a half at a couple of shows in London, and including today on SEOmoz Q&A, I've heard polarised opinions on this topic, so thought I'd throw it out there to see what other people think, and what evidence/experience people have with this. Basically - some people are saying older links are worth less than new links, and others are saying old link are worth don't devalue and are possibly worth more. I have to admit, I don't have a strong opinion on this, as it is really hard to judge on live projects, and I think it is a case by case thing. Any thoughts?
