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 non existant pages
Hi I have 100's of URL's appearing in Search Console for example: ?p=1_1 These go to on to 5_200 etc.. I have tried to do htaccess and the mod rewrite is on as I can redirect directories to the root i.e RewriteRule ^web_example(.*)$ /$1 [R=301,N,L] However I have tried all kinds of variations to redirect ?p= and either it doesn't work at all or it crashes the website. Can anyone point me in the right direction to fix this.

Sudden drop in Rankings after 301 redirect
Greetings to Moz Community. Couple of months back, I have redirected my old blog to a new URL with 301 redirect because of spammy links pointed to my old blog. I have transfer all the posts manually, changed the permalink structure and 301 redirected every individual URL. All the ranking were boosted within couple of weeks and regained the traffic. After a month I have observed, the links pointed to old site are showing up in Webmaster Tools for the new domain. I was shocked (no previous experience) and again Disavowed all links. Today, all the positions went down for new domain. My questions are: 1. Did the Disavow tool worked this time with new domain? All the links pointed to old domain were devaluated? Is this the reason for ranking drop? Or 2. 301 Old domain with Unnatural links causes the issue? 3. Removing 301 will help to regain few keyword positions? I'm taking this as a case study. Already removed the 301 redirect. Looking for solid discussion.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
