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 redirect syntax for htaccess
I'm working on some htaccess redirects for a few stray pages and have come across a few different varieties of 301s that are confusing me a bit....Most sources suggest: Redirect 301 /pageA.html http://www.site.com/pageB.html or using some combination of: RewriteRule + RewriteCond + RegEx I've also found examples of: RedirectPermanent /pageA.html http://www.site.com/pageB.html I'm confused because our current htaccess file has quite a few (working) redirects that look like this: Redirect permanent /pageA.html http://www.site.com/pageB.html This syntax seems to work, but I'm yet to find another Redirect permanent in the wild, only examples of Redirect 301 or RedirectPermanent Is there any difference between these? Would I benefit at all from replacing Redirect permanent with Redirect 301?

Proper 301 redirect code for http to https
I see lots of suggestions on the web for forwarding http to https. I've got several existing sites that want to take advantage of the SSL boost for SEO (however slight) and I don't want to lose SEO placements in the process. I can force all pages to be viewed through the SSL - that's no problem. But for SEO reasons, do I need to do a 301 redirect line of code for every page in the site to the new "https" version? Or is there a way to catch all with one line of code that Google, etc. will recognize & honor?

301 redirects delay in picking up
Hi I have been involved in the redesign/development of a website which has up until now had a lot of international traffic. On day of migration I uploaded all the 301 redirects to the website (wordpress) using Simple 301 redirect plugin. I tested a number of them and they appeared to be working. I also submitted the new sitemaps to Search Console. Since migration international traffic - particularly from countries such as india, Phillipines, Sri Lanka etc have significantly dropped off whereas the local traffic and some of the international traffic such as USA has remained fairly consistent. Looking at Analytics and entrances recently it appears as though search results are/were showing a number of pages with 404's (one in particular which received significant traffic and for which I had created a 301 redirection) - I have checked this page using the old url and it re-directs correctly for me and today asked a colleague in India to also check - he is getting the redirection fine. Does Google.in take a significantly longer time to pick these up in search results? Or am I missing something?

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 -
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?

301 Redirect "wildcard" question
I have been looking at the SEOmoz redirect guide for some advice but I can't seem to find the answer : http://www.seomoz.org/learn-seo/redirection I have lots of URLs from a previous version of a site that look like the following: sitename.com/-c-25.html?sort=2d&page=1 sitename.com/-c-25.html?sort=3a&page=1 etc etc. I want to write a redirect so whenever a URL with the terms "-c-25.html" is requested it redirects to a specified page, regardless of what comes after the question mark. These URLs were created by our previous ecommerce software. The 'c' is for category, and each page of the cateogry created a different URL. I want to do these so I can rediect all of these URLs to the appropraite new cateogry page in a single redirect. Thanks for any help.
