301 redirect: canonical or non canonical?
-
Hi,
Newbie alert!
I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly.
The current site uses canonical header tags. The new site will also use canonical tags.
Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new?
Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case?
Thx in anticipation.

The most accurate way is to do it manually. Doing a site:YOURDOMAIN.com in Google will alert you to most of the ugly URLs you want to get rid of.

Thanks for that David . . . makes sense.
Can you recommend any tools to help with this job or is it still mostly a manual process?
Cheers.

"Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new?"
Any URL's that are indexed should be redirected to the correct version. For example if you have both a database URL and a canonical URL both indexed in search results, then they both should be sent to the correct version.
Also, having only canonical URLs in your submitted sitemaps will help to remove a lot of these, even without redirects.

Ok, here is my understanding regarding canonicals and how it works with redirect. 301 redirect means the old URL is shifting its all value and user to the new domain (unlike 302 that only derives traffic but contain the URL value to itself only).
Whereas Canonicals indicates Google the preferred version of the domain so theoretically if you use the canonicals on every page Google should pick the redirected page as 301 will take Google to the final destination anyways…
What will I do?
If Possible, I will map all the redirected URLs and remove canonicals from there just to be on the safe side but I don’t think having there will be much of a difference as Google as at least that smart.
Hope this helps!

301 Redirects Relating to Your XML Sitemap
Lets say you've got a website and it had quite a few pages that for lack of a better term were like an infomercial, 6-8 pages of slightly different topics all essentially saying the same thing. You could all but call it spam. www.site.com/page-1 www.site.com/page-2 www.site.com/page-3 www.site.com/page-4 www.site.com/page-5 www.site.com/page-6 Now you decided to consolidate all of that information into one well written page, and while the previous pages may have been a bit spammy they did indeed have SOME juice to pass through. Your new page is: www.site.com/not-spammy-page You then 301 redirect the previous 'spammy' pages to the new page. Now the question, do I immediately re-submit an updated xml sitemap to Google, which would NOT contain all of the old URL's, thus making me assume Google would miss the 301 redirect/seo juice. Or do I wait a week or two, allow Google to re-crawl the site and see the existing 301's and once they've taken notice of the changes submit an updated sitemap? Probably a stupid question I understand, but I want to ensure I'm following the best practices given the situation, thanks guys and girls!

Simple 301 redirect a subfolder to another subfolder
Hi, I have a number of sub-folders that I have to move, each of which contains a number of files. subfolder A has files a, b & c subfolder B has files d, e & f
Technical SEO | | aactive
subfolder C has files g, h & i A, B & C folders need to be X, Y & Z Will the following work? RewriteRule ^subfolder-A/* http://www.domain.com/subfolder-X/ [R=301,L]
RewriteRule ^subfolder-B/* http://www.domain.com/subfolder-Y/ [R=301,L]
RewriteRule ^subfolder-C/* http://www.domain.com/subfolder-Z/ [R=301,L] will this result in visitors to http://www.domain.com/subfolder-B/f.html being redirected to http://www.domain.com/subfolder-Y/f.html? All on the same domain. in reality we are talking hundreds of sub folders and thousands of files so we don't want to have to reference every file individually in the htaccess. Thanks0 -
Switching from a .org to .io (301 domain redirect)
I'm considering switching my main site from a .org to .io address; the .org is an exact match domain which helped to kickstart it a few years ago and now has about 50% repeat visitors, but was thrown off the Apple affiliation program for trademark infringement. I've found and purchased a nice (non-infringing) .io domain, and I've read the advice here on how to properly 301 the old domain; but my question is - does it matter that it's .io? Is this going to significantly hurt my rankings, even when everything has been 301'd properly? Another thought I had is that I may actually come out better off in the long run, what with Google penalties being applied to exact match domains. Is this a ranking suicide? If so, I'm tempted to leave it as is; even without the affiliation, it's making a good amount every month in ad fees that I don't want to disrupt. Thanks all!

A script to automatically write 301 redirect rules to htaccess?
I was wondering if anyone could help provide some resources on how to automatically write 301 redirect rules to htaccess. Allow me to explain... I'm building a new website and the primary users are businesses. They have their own profile pages on the site. The URL is based off of their Company Name. In the event that they decided to change their name... reasons being, perhaps they mispelled it the first time, or they're removing LLC or adding Inc, I want to also change the URL and redirect the old URL to the new URL. Since the URL is based off of their Company Name, making a change to the company name would make a change to the URL. I know it doesn't have to work this way, but for our purpose this works best. In case the old URL had any links to it, I wanted to see if there was an way to automatically update an htaccess file with a 301 redirect from the old URL to the new one. Could anyone point me in the right direction of how to do this? Perhaps a sample script. I've done a lot of searches on Google and can't seem to find anything. e.g. Original:
Technical SEO | | bimmer540
Name: XYZ Widgets
URL: website.com/xyz-widgets New - business changes their company name in their profile:
Name: XYZ Widgets, Inc.
URL: website.com/xyz-widgets-inc Upon the user saving the changes in their profile, I'd like to write a 301 redirect to an htaccess file:
Redirect 301 /xyz-widgets http://www.website.com/xyz-widgets-inc I know how to manually write redirects and I've got a pretty smart web developer. We've just never triggered a script to automatically write to an htaccess file before. Is this possible? Any resources are appreciated. Any security risks? Thanks!0 -
Will bad things happen if I cancel 301 site redirect?
Hi, please someone help! We have two identical websites, say A & B. Because of the not so good SEO establishment, site B was built and site A was 301 redirected to site B weeks ago. For some reasons, we have to reuse site A, which means we have to cancel the 301 redirection. (Sound a little crazy) So the question are: 1. Can we conduct the action? 2. If we cant, what's the reason? 3. If we can, what would be the best practice? Thanks for help in advance! Plus: we also CARE what would happen to site B if the 301 is cancelled? Will it grow healthy like a new site?

What tools produce a complete list of all URLs for 301 redirects?
I am project managing the rebuild of a major corporate website and need to set up 301 redirects from the old pages to the new ones. The problem is that the old site sits on multiple CMS platforms so there is no way I can get a list of pages from the old CMS. Is there a good tool out there that will crawl through all the sites and produce a nice spreadsheet with all the URLs on it? Somebody mentioned Xenu but I have never used it. Any recommendations? Thanks -Adrian

301 Redirect vs Domain Alias
We have hundreds of domains which are either alternate spelling of our primary domain or close keyword names we didn't want our competitor to get before us. The primary domain is running on a dedicated Windows server running IIS6 and set to a static IP. Since it is a static IP and not using host headers any domain pointed to the static IP will immediately show the contents of the site, however the domain will be whatever was typed. Which could be the primary domain or an alias. Two concerns. First, is it possible that Google would penalize us for the alias domains or dilute our primary domain "juice"? Second, we need to properly track traffic from the alias domains. We could make unique content for those performing well and sell or let expire those that are sending no traffic. It's not my goal to use the alias domains to artificially pump up our primary domain. We have them for spelling errors and direct traffic. What is the best practice for handling one or both of these issues?
