Using a 302 instead of a 301
-
I am trying to figure out the best way to garner the most amount of link value.
We have an app that lives on a sub-domain ... For the purposes of this question, let's call it app.mydomain.com. We provide a service with this app that requires clients (with very high ranking websites) to link into app located on the sub-domain.
Would I garner more authority if had the high ranking client website link into a url that wasn't a sub-domain and redirect it using a 302?
For example: What if I created a 302 that was www.mydomain.com/app and have it redirected to the sub-domain version of app.mydomain.com?
Additionally am I correct to assume that a 301 would merely pass that value to the sub domain and NOT provide much value to the root?

Just to clarify, I want to direct the link juice to: www.mydomain.com from app.mydomain.com. As these high profile websites will be linking to the app.
My idea was to have them link to a page on the www.mydomain.com/app that I would effectively redirect back to app.mydomain.com.
But if I use a 301, the 301 will direct link juice back toward the sub domain (app.mydomain.com).
So my question is ... will the 302 keep the juice at the www version (not pass the juice)
Hopefully this makes sense. The other option is to simply let them link to the app. and add a canonical tag that points the juice back to the www version.

It seems your on the righ track as a 302 Redirect is a temporary redirect
and passes 0% of link juice according to SEOMOZ: http://www.seomoz.org/learn-seo/redirectionAlso The "root domain" redirected page will still retain its PageRank, MozRank,
Page Authority and Traffic Value – and the detour page will not accumulate any.You are also correct about the 301:
A 301 Redirect is a permanent redirect which passes between 90-99% of link juice
according to SEOMOZ: http://www.seomoz.org/learn-seo/redirectionKeep in mind that on this same page SEOMOZ goes on to say "and in most cases (302 redirect) should not be used.
Also if kept to long a 302 will eventually slide in rankingsI think yes you will garner more link value using a subfolder then a subdomain
As you will see posted also on SEOMOZ:"5. Subdomains or Sub-folders
Since search engines keep different metrics for domains than they do subdomains,
it is recommended that webmasters place link worthy content like blogs in subfolders
rather than subdomains. (i.e. www.example.com/blog/ rather than blog.example.com)
The notable exception to this is language specific websites. (i.e. en.example.com for english)"http://www.seomoz.org/learn-seo/domain
But the main point here is will you gain anything to your root domain while it
has a 302 and redrecting to another pagePersonally, I would avoid the 302 and move the page "app.mydomain.com" to the subfolder "www.mydomain.com/app"
Having the old page url "app.mydomain.com" 301 redirect to the subfolder "www.mydomain.com/app"
passing 90-99% of the juice -
What subdomain are you trying to get link juice for? app.mydomain.com or www.mydomain.com?
Never use a 302. You lose 100% of link juice.
With a 301, you will still lose a little, maybe 10% or so, but you will pass the link juice on to the app.mydomain.com
But if you are trying to get the most Link Juice to the root domain mydomain.com, then I would just suggest linking directly to the app.mydomain.com

Htaccess 301 regex question
I need some help with a regex for htaccess. I want to 301 redirect this: http://olddomain.com/oldsubdir/fruit.aspx to this: https://www.newdomain.com/newsubdir/FRUIT changes: different protocol (http -> https) add 'www.' different domain (olddomain and newdomain are constants) different subdirectory (oldsubdir and newsubdir are constants) 'fruit' is a variable (which will contain only letters [a-zA-Z]) is it possible to make 'fruit' UPPER case on the redirect (so 'fruit' -> 'FRUIT') remove '.aspx' I think it's something like this (placed in the .htaccess file in the root directory of olddomain): RedirectMatch 301 /oldsubdir/(.*).aspx https://www.newdomain.com/newsubdir/$1 Thanks.

Should we Use rel=canonical in ccTLDs websites
We have multilingual eCommerce websites with some content variations but majority of the content remains the same We have used rel=alternate hreflang on corresponding ccTLDs respective countries. for example on example.com -which is the oldest of these sites- we have used Now should we also use link rel="canonical" href="example.com" on all ccTLDs? What are the advantages and disadvantages of using it?

Canonical links apparently not used by google
hi, I do have an ecommerce website (www.soundcreation.ro) which in the last 3 months had a drop in the SERP. Started to look around in GWT what is happening. Google is reporting a lot of duplicate meta-tags (and meta-titles problem). But 99% of them had already canonical links setted. I tried to optimize my product listings with the new "prev", "next" tags and introduced also the "view-all" canonical link to help Google identify the appropiate product listing pages. SeoMoz is not reporting thos duplicate meta issues. Here is an example of the same page with different links, but with the same common canonical and reported by GWT "duplicate title tag": http://www.soundcreation.ro/chitare-chitari-electroacustice-cid10-pageall/http://www.soundcreation.ro/chitare-chitari-electroacustice-cid10/http://www.soundcreation.ro/chitare-chitari-electroacustice-cid10_999/http://www.soundcreation.ro/chitare-electro-acustice-cid10_1510/What could be the issue?- only that gwt is not refreshing as should be, keeping old errors?- if so, then there is an other serious issue because of why our PR is dropping on several pages?- do we have other problem with the site, which ends up with google penalizing us? Thank you for your ideas!

301 a page and then remove the 301
I have a real estate website that has a city hub page. All the homes for sale within a city are linked to from this hub page. Certain small cities may have one home on the market for a month and then not have any homes on the market for months or years. I call them "Ghost Cities". This problem happens across many cities at any point in time. The resulting city hub pages are left with little to no content. We are throwing around the idea of 301 redirecting these "Ghost City" pages to a page higher up in the hierarchy (Think state or county) until we get new homes for sale in the city. At that point we would remove the 301. Any thoughts on this strategy? Is it bad to turn 301s on and off like that? Thanks!
