How long should I keep 301 redirects?
-
I have modified a the URL structure of a whole section of a website and used mod_rewrite 301 redirect to match the new structure. Now that was around 3 months ago and I was wondering how long should I keep this redirect for?
As it is a new website I am quite sure that there are no links around with the old URL structure but still I can see the google bot trying from time to time to access the old URL structure. Shouldn't the google bot learn from this 301 redirect and not go anymore for the old URL?
-
Thanks to both of you for your answers. I will then leave my rewrite rules just in case. I guess they are not slowing down access to the website as they are really simple and quite standard. I suppose that google takes longer to "learn" the new URLs through the redirects.

I would agree with Marcus' answer on this one.
Another question as an off-shoot from this one would be: What is the performance loss in checking each request against your htaccess rules?
If the answer is none, or very little, then perhaps keeping the 301 forever isn't a bad idea at all. You never know how long people will be linking towards those 301'd pages. I personally have some pages just like this which have been redirecting visitors for as many as 5 years, because it's better to keep the link juice than to end up as 404s.

The simple answer is... forever, unless you have some pressing reason to remove them. Certainly, I would keep them there till I knew there was no indexation of these other links and no requests for them for a say, 12 month period.
If you have external links pointing to any of these old pages, then again, that is another argument for keeping them in place.
Just leave them there, comment them as legacy in redirection script and forget about them and focus on something else.

Hope this helps.
Marcus

Reusing an already 301 redirected URL for a very important keyword
I have a question about reusing an already 301 redirected URL Till now I never reused an URLs that has been already redirected with a 301 redirect. However, I just started working on a website where in past they created a lot of 301 redirects without thinking about the future, and now certain URLs, that are currently redirected with a 301, would be very useful (exact match) and needed (for some of the most important keywords for this specific business), to maintain an optimal, homogeneous and "beautiful" URL structure. Has any of you ever reused a URL that was previously redirected with a 301 redirect? If yes what are your experiences with it? Can content on the reused URL (that was previously 301 redirected and than the redirect removed) normally rank if the page is reestablished and the redirect is removed (and you do great content, on page, internal linking, backlinking, .... ) or is such an URL risky / not recommended / "burned" forever and not recommended to be reused again... especially for very important keywords since it present the exact match ?! Thank you very much for all your help! Regards

How to redirect 302 status to 301 status code using wordpress
I just ran the link opportunity option within site explorer and it shows that 31 pages are currently in a 302 status. Should I try to convert the 302's to 301's? And what is the easiest way to do this? I see several wordpress plugins that claim to do 301 redirects but I don't know which to choose. Any help would be greatly appreciated!

Redirect URLS with 301 twice
Hello, I had asked my client to ask her web developer to move to a more simplified URL structure. There was a folder called "home" after the root which served no purpose. I asked for the URLs to be redirected using 301 to the new URLs which did not have this structure. However, the web developer didn't agree and decided to just rename the "home" folder "p". I don't know why he did this. We argued the case and he then created the URL structure we wanted. Initially he had 301 redirected the old URLS (the one with "Home") to his new version (the one with the "p"). When we asked for the more simplified URL after arguing, he just redirected all the "p" URLS to the PAGE NOT FOUND. However, remember, all the original URLs are now being redirected to the PAGE NOT FOUND as a result. The problems I see are these unless he redirects again: The new simplified URLS have to start from scratch to rank 2)We have duplicated content - two URLs with the same content Customers clicking products in the SERPs will currently find that they are being redirect to the 404 page. I understand that redirection has to occur but my questions are these: Is it ok to redirect twice with 301 - so old URL to the "p" version then to final simplified version. Will link juice be lost doing this twice? If he redirects from the original URLS to the final version missing out the "p" version, what should happen to the "p" version - they are currently indexed. Any help would be appreciated. Thanks

301 redirect from Blogger
Hello, I have a client with a Wordpress network of blogs, each blog is owned by a different blogger. Many of them were migrated time ago from Blogger. I have seen that the way used to redirect them is a meta refresh, so no authority is being passed. I cannot find any reliable way of making a 301 from Blogger, There are some plugins, but I'm afraid of using them. Any of you have experience with this situation please? I have even thought about placing a global rel canonical before the meta refresh, but I think that here the problem is the meta refresh itself.... Thank you in advance

How to safely reduce the number of 301 redirects / should we be adding so many?
Hi All, We lost a lot of good rankings over the weekend with no obvious cause. Our top keyword went from p3 to p12, for example. Site speed is pretty bad (slower than 92% of sites!) but it has always been pretty bad. I'm on to the dev team to try and crunch this (beyond image optimisation) but I know that something I can effect is the number of 301 redirects we have in place. We have hundreds of 301s because we've been, perhaps incorrectly, adding one every time we find a new crawl error in GWT and it isn't because of a broken link on our site or on an external site where we can't track down the webmaster to fix the link. Is this bad practice, and should we just ignore 404s caused by external broken URLs? If we wanted to reduce these numbers, should we think about removing ones that are only in place due to external broken URLs? Any other tips for safely reducing the number of 301s? Thanks, all! Chris

200 Redirects for SEO instead of 301
We are working with a company on re-platforming our website. On a call yesterday they outlined a strategy to use 200 redirects for our top keywords instead of 301s. I am not familiar with this type of redirect and was wondering if anyone could provide some more insight.

Multiple Domains, Same IP address, redirecting to preferred domain (301) -site is still indexed under wrong domains
Due to acquisitions over time and the merging of many microsites into one major site, we currently have 20+ TLD's pointing to the same IP address as our "preferred domain:" for our consolidated website http://goo.gl/gH33w. They are all set up as 301 redirects on apache - including both the www and non www versions. When we launched this consolidated website, (April 2010) we accidentally left the settings of our site open to accept any of our domains on the same IP. This was later fixed but unfortunately Google indexed our site under multiple of these URL's (ignoring the redirects) using the same content from our main website but swapping out the domain. We added some additional redirects on apache to redirect these individual pages pages indexed under the wrong domain to the same page under our main domain http://goo.gl/gH33w. This seemed to help resolve the issue and moved hundreds of pages off the index. However, in December of 2010 we made significant changes in our external dns for our ip addresses and now since December, we see pages indexed under these redirecting domains on the rise again. If you do a search query of : site:laboratoryid.com you will see a few hundred examples of pages indexed under the wrong domain. When you click on the link, it does redirect to the same page but under the preferred domain. So the redirect is working and has been confirmed as 301. But for some reason Google continues to crawl our site and index under this incorrect domains. Why is this? Is there a setting we are missing? These domain level and page level redirects should be decreasing the pages being indexed under the wrong domain but it appears it is doing the reverse. All of these old domains currently point to our production IP address where are preferred domain is also pointing. Could this be the issue? None of the pages indexed today are from the old version of these sites. They only seem to be the new content from the new site but not under the preferred domain. Any insight would be much appreciated because we have tried many things without success to get this resolved.
