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.

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.

Redirecting dofollow, high-domain-authority links from one site to another: good idea?
I have two sites that offer help for freelance writers. The first gets almost no search traffic and is very low priority for me. The second is my main priority and gets substantial search traffic. The low-priority site has a significant number of dofollow backlinks from high-domain-authority sites. Is it a good idea to 301 redirect these links to similar/related posts on my high-priority site? Would this potentially boost the SEO of my high-priority site? Thanks for any help!

Redirects affect on page and domain authority
Hi - excuse me if this is stupid question but I'm rather new to this. Currently the PA for the home page is 16 and the DA 28 and I have some concerns that my efforts are being diluted. When I use OSE on www.sassandgrace.co.uk I get different link results to sassandgrace.co.uk but there is a redirect in place to sassandgrace.co.uk and cannot run a crawl report, for example, on www.sassandgrace.co.uk. The PA and DA are identical for each but the number of links different With a smallish number of links pointing to each but with a redirect in place, am I losing some of the effect or is having the redirect in place giving me all the credit for links to both addresses? Thanks

Shortened URLs Passing Link Equity?
Hi everyone, I was going through a competitor's backlinks, and I noticed they had a number of links from ow.ly and bit.ly that according to Open Site Explorer were passing link equity with PA in the 40 and DA in the 90s. How does that happen? And, how can I duplicate that? I thought those services just shortened your URLs for Twitter feeds mostly, and Twitter no-followed everything. Thanks for any assistance you can provide! Ruben

PHP Redirection better than Nofollow?
Hello, if I have affiliate outbound links in my blogs, what's better in terms of SEO, to use PHP Redirection or Nofollow for those links? For example, instead of using nofollow for the outbound affiliate links, I can use some plugin for WordPress that does this: mydomain.com/affiliatesitename1 -> redirects to the affiliate link1. mydomain.com/affiliatesitename2 -> redirects to the affiliate link2. mydomain.com/affiliatesitename3 -> redirects to the affiliate link3. Is this better? Thanks.

Links or Redirect?
My client's company has just acquired another company in the same industry and with that acquisition came two websites; companyname.com and companyname.co.uk. companyname.com has PA13 and DA10, companyname.co.uk has PA15 and DA10. At the moment, the two companies are to be run as separate companies but will become fully merged in time. My client's own website is brand new (PA1 and DA) and I'm wondering what is the best way to use these other two sites to improve my client's search ranking. Should I use the two sites to link to my client (these would be logical and natural links e.g. explaining the acquisition, under new management) or would it simply be better to redirect the domains to the new site? Many thanks

Will Google penalize for redirects related to a company merger?
Company A is set to acquire Company B. As part of the merger agreement, Company A will be redirecting the linking domains of Company B's website (over 1,000 links) to company A's website. Will Google penalize Company A for redirecting Company B's 1,000 linking domains to Company A's website at one time? If so, would it be better for Company A to redirect Company B's 1,000 linking domains in waves?
