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 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?

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 with index.asp
I am very new to all of this so forgive the newbie questions I will get better. Ok so after starting a campaign I see that I have many issues including where some pages are being deemed as duplicate content. 1. The report says the http://lucid8.com has duplicate content on 2 other pages 2. When I look at them it shows that http://lucid8.com/index.asp and http://www.lucid8.com are duplicates. 3. Really these are the exactly the same page because the default page that is opened for www.lucid8.com http://www.lucid8.com etc always opens the index.asp page. 4. Now I read that I should do permanent redirects and how to do this via IIS and I tried to do a redirect from index.asp to www.lucid8.com but that does not work because www.lucid8.com is pointing to index.asp and so we end up in a circle. So the question is how do I get rid of these duplicate page references without causing problems. Thanks

301 redirect not working
Hi there! I have recently moved a domain that has been indexed by google and setup redirects so that it forwards to the new domain. It seems like the only redirect that actually is working is the canonical and main domain but every other page and or page nested within a folder are not working. Here is an example of some of the redirects. Am I doing this wrong? It seems to be going to the new domain but can't find the actual pages.... RewriteEngine On

301 Redirect How Long until the juice passes through to new site
Hi Guys, Following on from a question i asked last week in regard to a 301 http://www.seomoz.org/q/301-redirect-have-no-ranking I was thinking that i had some kind of issue on the site, although i have gone over it with a fine tooth comb i cannot find any issue's and from the amount of reads the thread has had im sure if there was something obvious it would have been pointed out. So i am quite confident the 301 from site A to site B is fine and working as intended, so my question is how long should it take until the juice is passed From site A to Site B as its 9 weeks now and still down 85% on traffic and even text for my home page if copied into the search bar don't bring up my site Bing is fine and did not see any real traffic drops but Google is not giving me back the rankings i had prior Whenever i have done a 301 before the rankings pretty steady and i see no real loss in rankings but this time ... painful all changes in WMT made

301 redirects & merging two sites into one
We have a client that has two sites that rank well for different searches in their market. The main pages ranking are things like advice articles and news pieces. For various reasons, they just want one site. I believe they need to duplicate the content from the outgoing site and place it on the main site, with a 301 redirect from each old page to each new one. What happens when they eventually want to redirect the entire domain? Would these smaller, internal redirects become obsolete, therefore removing any link value they once had? I am not sure how this works or if there is a best practice way to do this. Thanks Gareth

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
