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!

Redirection chain and Javascript Redirect
Hi, A redirection chain is usually defined as a page redirecting to another page which itself is another redirection. URL1 ---(301/302)---> URL2 ---(301/302)---> URL3 But what about Javascript redirect? They seem to be a different beast: URL1 ---(301/302)---> URL2 ---(200 then Javascript redirect)---> URL3 From what I know if the javascript redirect is instant Google counts it as a 301 permanent redirection, but I'm still not sure about if this counts as a redirection chain. Most of the tools (such as moz) only see the first redirection. So is that scenario a redirection chain or no?

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?

Rel=Canonical, WWW vs non WWW and SEO
Okay so I'm a bit of a loss here. For what ever reason just about every single Wordpress site I has will turn www.mysite.com into mysite.com in the browser bar. I assume this is the rel=canonical tag at work, there are no 301s on my site. When I use the Open Site Explorer and type in www.mysite.com it shows a domain authority of around 40 and a few hundred backlinks... and then I get the message. Oh Hey! It looks like that URL redirects to XXXXXX. Would you like to see data for <a class="clickable redirects">that URL instead</a>? So if I click to see this data instead I have less than half of that domain authority and about 2 backlinks. *** Does this make a difference SEO wise? Should my non WWW be redirecting to my WWW instead because that's where the domain authority and backlinks are? Why am I getting two different domain authority and backlink counts if they are essentially the same? Or am I wrong and all that link juice and authority passes just the same?

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?

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.
