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.

Should I use the on classified listing pages that have expired?
We have went back and forth on this and wanted to get some outside input. I work for an online listing website that has classified ads on it. These ads are generated by companies on our site advertising weekend events around the country. We have about 10,000 companies that use our service to generate their online ads. This means that we have thousands of pages being created each week. The ads have lots of content: pictures, sale descriptions, and company information. After the ads have expired, and the sale is no longer happening, we are currently placing the in the heads of each page. The content is not relative anymore since the ad has ended. The only value the content offers a searcher is the images (there are millions on expired ads) and the descriptions of the items for sale. We currently are the leader in our industry and control most of the top spots on Google for our keywords. We have been worried about cluttering up the search results with pages of ads that are expired. In our Moz account right now we currently have over 28k crawler warnings alerting us to the being in the page heads of the expired ads. Seeing those warnings have made us nervous and second guessing what we are doing. Does anybody have any thoughts on this? Should we continue with placing the in the heads of the expired ads, or should we be allowing search engines to index the old pages. I have seen websites with discontinued products keeping the products around so that individuals can look up past information. This is the closest thing have seen to our situation. Any help or insight would be greatly appreciated! -Matt

All URLs in the site is 302 redirected to itself
Hi everyone, I have a problem with a website wherein all URLs (homepage, inner pages) are 302 redirected. This is based on Screaming Frog crawl. But the weird thing is that they are 302 redirected to themselves which doesn't make any sense. Example:

https://www.example.com.au/ is 302 redirected to https://www.example.com.au/ https://www.example.com.au/shop is 302 redirected to https://www.example.com.au/shop https://www.example.com.au/shop/dresses is 302 redirected to https://www.example.com.au/shop/dresses Have you encountered this issue? What did you do to fix it? Would be very glad to hear your responses. Cheers!0 -

Does Google Index URLs that are always 302 redirected
Hello community Due to the architecture of our site, we have a bunch of URLs that are 302 redirected to the same URL plus a query string appended to it. For example: www.example.com/hello.html is 302 redirected to www.example.com/hello.html?___store=abc The www.example.com/hello.html?___store=abc page also has a link canonical tag to www.example.com/hello.html In the above example, can www.example.com/hello.html every be Indexed, by google as I assume the googlebot will always be redirected to www.example.com/hello.html?___store=abc and will never see www.example.com/hello.html ? Thanks in advance for the 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?

Are there any negative effects to using a 301 redirect from a page to another internal page?
For example, from http://www.dog.com/toys to http://www.dog.com/chew-toys. In my situation, the main purpose of the 301 redirect is to replace the page with a new internal page that has a better optimized URL. This will be executed across multiple pages (about 20). None of these pages hold any search rankings but do carry a decent amount of page authority.

How do you implement dynamic SEO-friendly URLs using Ajax without using hashbangs?
We're building a new website platform and are using Ajax as the method for allowing users to select from filters. We want to dynamically insert elements into the URL as the filters are selected so that search engines will index multiple combinations of filters. We're struggling to see how this is possible using symfony framework. We've used www.gizmodo.com as an example of how to achieve SEO and user-friendly URLs but this is only an example of achieving this for static content. We would prefer to go down a route that didn't involve hashbangs if possible. Does anyone have any experience using hashbangs and how it affected their site? Any advice on the above would be gratefully received.
