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.

Slug redirect to existing subdomain?
Hi everyone, I'm Levi, new here and new in the world of SEO so please don't judge if my question is silly. Back on the days when my website was built we tought of having subdomains to help with SEO. We have a couple subdomains set up https://stansted.tonorwich.uk, https://heathrow.tonorwich.uk, https://gatwick.tonorwich.uk, https://luton.tonorwich.uk etc .
Link Building | | Leviiii
We do have some content on these, but from seo perspective creating a slug and redirecting it to the subdomains would be beneficial? Would it make any difference at all, good or bad? Ex. Creating
https://tonorwich.uk/taxi-minibus-tofrom-stansted and redirecting it to https://stansted.tonorwich.uk
Will this help or we better create different content on the slugs? Waiting for your opinions.
Thanks in advance.0 -

Finding links online that already exist as link juice based on search results
I'm curious about this, I can't find anything on the net that talks about it. I wrote an article about it on squidoo and have had no responses so I am thinking this is very rare subject. The question is I have done some backlink research with my competitors with linkdetective.com and found many links (even follow ones) related to sites that provide search results. Here are a link about what I am talking about as an example, I have found many more besides this one. http://search.lphant.com/es/webResults.html?q=free%20scrabble%20dictionary&hl=en&page=1&src=hmp_es&ref=1 My site appears in those results. When looking at the source there is no "nofollow". I found this page because linkdetective.com had this link listed pointing to my competitor. Are these valid backlinks? What I have been doing is adding these links to http://www.google.com/addurl so that Google knows about them. Is there something I am missing or are these valid?

Image only badges giving link juice!?!?
I see some chatter about badges, but no clear definition. A collegue of mine instituted badges on clients website, but these badges are only an image w/ hyperlink; no textual content. He is confident that this has worked successfully before as a link building strategy, which blew my mind. I thought we needed some text, and obviously optimizes anchor text for biggest benefit. Are these simple badges helpful, or do we need some html in there!? He also routes them through bit.ly to track impressions and clicks.. does that have any effect as well? Thanks!

Do press releases add any link juice?
I've been told by PR Web that anchor text in their press releases will add SEO value and increase our page rank. They even charge more for releases that include the ability to link specific keywords to specific pages (anchor text keywords). So - do such press releases really add any page rank to our site? Here's our press release: http://www.prweb.com/releases/2011/5/prweb8289567.htm Thanks, Alex
