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.

Back link from site with DA of 72 to a website domain. Clicking on the link redirects to our website not the attended one.
Hi,
Link Building | | JIMBO16
I've ran a back link check and discovered a good back link to a site which then gets redirected back to my company's website. I have a feeling that an old SEO agency has purchased a small website which has a decent link back from a relevant organisation with a high Domain authority and then redirects the domain to our website to get the link juice. What are your thought on this? Is this really bad practise and possibly damaging? Thanks, Jim0 -
Correctly Dealing With Redirects
Hi, Hope someone might be able to help me with this. One of our sites was built badly and the orginal url structure was to have mydomain.com/index.php but these have been changed to mydomain.com by a developer who has put the redirects in place. The problem is that in webmaster tools my link count has dropped to 18 from nearly 2300. I am assuming that Google is not seeing the redirect, any advice would be greatly appreciated. Thanks

Parameter In URL passing SEO Value
Helllo I need help understanding the following scenario. We do campaign tracking for number of our sites using urt parameters. These are normally PR links with utm parameters. I am not sure if we should remove the utm parameter and forget about tracking the links completely if it offers an added SEO value with direct links OR we just keep using utm parameters for PR tracking and use canonical tag instead on respective pages. For me SEO value is most important. But i am trying to understand what i am losing or gaining. Kindly sugggest Thanks

Do subdomains (eg .blogspot.com) carry the same link juice as a .com or .co.uk?
Hi guys. Just wondered what people's thoughts were on the value of a link from a subdomain vs a .com or .co.uk - I have several clients operating within the UK crafts sector, and there are a huge number of blogspot blogs with decent PR etc. Given that anyone can start one of these for free (and therefore theoretically get themselves hundreds of bogus links), I wonder whether they carry the same value as an independent site. I'll look forward to hearing everyone's thoughts 🙂

Do links within imbeddable widgets carry link juice?
I'm dipping my toes into infographic design. On of my desired outcomes is to gain links by having other sites embed my graphic. I'm considering using Tableau's interactive data visualization software to do so; thus creating a widget, embedding it on my blog, and including the embed code for others to post. Is it possible to include a juice passing link in such an infographic? I know its possible to include links inside the tableau graphic but not sure if they have straight SEO value. If these links are not juice passing would it be better to go with a simple image link that passes value?

Question about forwarding domains and link juice
We currently have a domain that has a small amount of inbound links: http://www.opensiteexplorer.org/www.1800wecoach.com/a!links We decided to switch over to a different domain name, which currently has 0 inbound links. What we were wondering is which would be better: link to the new domain from the old domain in a prominent location on all pages. or forward the old domain to the new domain? does forwarding a domain pass linkjuice?

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
