How long is it safe to use a 302 redirect?
-
Hi All,
Lets assume there is site A and site B, both sites are live on the internet today as standalone businesses, but they sell very similar products.
Site B has built up some link equity and will eventually become the domain for site A due to an organisational re-brand.
For the time being however site A will remain, but site B needs to disappear temporarily, but not lose the link equity which has been built up against it.
My current thinking is to 302 redirect site B to site A such that users and search bots accessing site B will be redirected to site A whilst leaving the link equity that exists against site B fully intact and allowing us to continue to grow it should we wish to.
The question is, does anybody have a view on how long it is safe to use a 302 temporary redirect for? i.e., is 8-10 months to long.
Thanks,
Ben

Thanks this is the kind of 2nd opinion I was looking for

Hi Ryan,
Sure, I've had 302's in place for years on some domains myself but this was more a question around two parts I guess:
- Has anyone seen it potentially have an impact to the site the 302 is pointing at?
- Has anyone found that having a 302 in place for a long period of time then has an impact on that domains ability to get re-picked up and indexed should the 302 become a 200 again.
If you take the "best practice" conversation out of the equation then my own personal view is there is no real risk in having a 302 in place for a considerable period of time.

Ben,
What exactly do you mean by "safe"? You CAN permanently use a 302. There is nothing preventing a webmaster from using a 302 for years. I would never advise doing such, but you are certainly able to do it if you were so inclined.

Okay. After re-reading the question (with my eyes open this time) I understand that the fact that no link jiuce will be passed to Site A (from Site B) is not an issue, rather you don't want to lose the existing link equity when you switch Site B back on and then 301 redirect Site A to Site B?
So, with that in mind - there is no specified 'acceptable' time limit attached to a 302 redirect, so you should be able to redirect without fear of being penalised, regardless of duration.
This is mentioned elsewhere on SEOMoz here: http://www.seomoz.org/qa/view/9994/302-redirect-timeframe
This is an interesting read however: http://www.seroundtable.com/archives/007233.html - just to keep things edgy ;o)

I know what best practice is folks - the question is "how long is it safe to use a 302 temporary redirect?"

-
Don't 302 in this case. Infact, don't 302 if at all possible as it passes ZERO link juice - 301 for this and get 90%+ link juice passed on. It does sound counter intuitive - certainly based on the titles MOVED PERMANENTLY etc but it is the best practice in this instance.
301 Moved Permanently
A 301 Redirect is a permanent redirect which passes between 90-99% of link juice (ranking power) to the redirected page. 301 refers to the HTTP status code for this type of redirect. In most instances, the 301 redirect is the best method for implementing redirects on a website.
302 Found (HTTP 1.1) / Moved Temporarily (HTTP 1.0)
A 302 Redirect is a temporary redirect and passes 0% of link juice (ranking power) and in most cases should not be used. The Internet runs on a protocol called HyperText Transfer Protocol (HTTP) which dictates how URLs work. It has two major versions, 1.0 and 1.1. In the first version 302 referred to the status code 'Moved Temporarily'. This was changed in version 1.1 to mean 'Found'.

The question is, does anybody have a view on how long it is safe to use a 302 temporary redirect for? i.e., is 8-10 months to long.
302's are for very small time frames such as a couple days. If you are looking for a suggested max time for a 302 I'll throw a month out as an absolute max, and that would probably be too long. I would be interested to hear feedback from other Mozzers on this topic.
Given your circumstance, I would 301 the pages, then 8-10 months later when the merger happens cancel the 301.
As long as the sites which currently link to Site B maintain their links, and those sites maintain their authority, then site B would not lose it's link equity. You are merely passing 90%+ of that link equity to site B for the 10 month downtime period.

New Site (redesign) Launched Without 301 Redirects to New Pages - Too Late to Add Redirects?
We recently launched a redesign/redevelopment of a site but failed to put 301 redirects in place for the old URL's. It's been about 2 months. Is it too late to even bother worrying about it at this point? The site has seen a notable decrease in site traffic/visits, perhaps due to this issue. I assume that once the search engines get an error on a URL, it will remove it from displaying in search results after a period of time. I'm just not sure if they will try to re-crawl those old URLs at some point and if so, it may be worth it to have those 301 redirects in place. Thank you.

Using disavow tool for 404s
Hey Community, Got a question about the disavow tool for you. My site is getting thousands of 404 errors from old blog/coupon/you name it sites linking to our old URL structure (which used underscores and ended in .jsp). It seems like the webmasters of these sites aren't answering back or haven't updated their sites in ages so it's returning 404 errors. If I disavow these domains and/or links will it clear out these 404 errors in Google? I read the GWT help page on it, but it didn't seem to answer this question. Feel free to ask any questions that may help you understand the issue more. Thanks for your help,

Using pictures from another domain
We are building several sites for several clients which will be using images from the manufacturer. Our dev team wants to insert the manufacturer's url for the images, instead of actually downloading the image and hosting on our server. There are thousands of images, so downloading images to our server will be time consuming, so we are looking for a shortcut.... however I'm concerned this will cause other issues. Is using manufactueresdomain.com/12345.jpg going to cause SEO issues? will this generate Google penalties? Since we are not able to control the image file name, we cannot optimize it. We will add Alt text and Title tag for each image, but the file name is random characters. How important is the file name for SEO?

301 Redirect of subdomain?
Fellow Mozzers, I'm having a hard time wrapping my brain around a redirect issue and thought it was worth posing the question to the Moz community. I did a search first but couldn't find the exact answer I was looking for. How does a 301 redirect work when you redirect a sub domain example.homepage.com to www.homepage.com but you keep the sub directories of example.homepage.com/page-1 active and are trying to rank them? I'm dealing with a current project where this is happening and this doesn't make sense to me, to redirect the subdomain if you're also trying to rank/create search traffic for pages, sub directories on example.homepage.com. This also get's into the debate of if a sub domain site is viewed as it's own website and therefore has to rank itself. If this is true, it seems like we're kind of killing the authority of the site by redirecting it. Additionally, www.homepage.com has a much stronger link profile than example.homepage.com I hope this makes sense. Any thoughts are appreciated. Thanks for your time.

Redirecting index.html to the root
Hi, I was wondering if there is a safe way to consolidate link juice on a single version of a home page. I find incoming links to my site that link to both mysite.com/ and mysite.com/index.html. I've decided to go with mysite.com/ as my main and only URL for the site and now I'd like to transfer all link juice from mysite.com/index.html to mysite.com/

301 or 302 Redirects to Mobile Site
When it's detected that a mobile device is accessing the site it has the ability to redirect from www.example.com to m.example.com. Does it make more sense to employ a 301 or 302 redirect here? Google says a 301 but does not explain why (although usually I stick to "when in doubt, 301") . It seems like a 302 would prevent passing link juice to the mobile site and having mobile-optimized results also showing up in Google's index. What is the preference here?

Changing a parent category and 301 redirecting
I have a set of three pages that are subpages of a parent. The structure is as follows: mysite.com/directory/personal-widgets mysite.com/directory/commercial-widgets mysite.com/directory/widgets-services The partent page name "directory" really isn't working for where I want these pages to evolve. So I want to change it to "guides" In a world without worrying about google, I would simply change the parent page to guides, so they look like this, and be done with it: mysite.com/guides/personal-widgets But, the obvious problem is that I have external links to the page now. And the pages have a nice PR. And they also have Facebook page Likes and I don't know if I'll lose those. I know that if I should do this I should redirect the pages to the new pages of course. My question is: Will redirecting the old URL to the new URL with a 301 cause anything negative to happen that I might not be expecting? Does Google dislike Redirects for any reason, or understand they are sometimes necessary?

How long until you see results?
How long does it typically take for SEO efforts to materialize? We recently performed a complete website redesign (new site, and am wondering how long we should wait until we analyze the results and possibly change our seo/keyword strategy?
