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!

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?

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?

Does it really matter to maintain 301 redirect after de-indexing of old URLs?
Today, I was reading latest blog post on SEOmoz blog about. Uncrawled 301s - A Quick Fix for When Relaunches Go Too Well This is very interesting study about 301 & How it useful to maintain traffic. I'm working on eCommerce website and I have done similar stuff on my website. I have big confusion to manage 301 redirect. My website generates new URLs due to following actions. Re-write dynamic URLs. Re-launch entire website on different eCommerce platform. [osCommerce to Magento Commerce] Re-name category. Trasfer one product from one category to another category. I'm managing my 301 redirect with old practice. Excel sheet data from Google webmaster tools and set specific new URLs for redirect. Hoooo... Now, I have 8.5K redirect in htaccess... And, I'm thinking it's too much. Can we remove old 301 redirect from htaccess or not? This is big question for me. Because, all pages are not hyperlink on external website. Google have just de-indexed old URLs and indexed new URLs. So, Is it require to maintain 301 redirect after Google process?

Is it worth setting up 301 redirects from old products to new products?
This year we are using a new supplier and they have provided us a product database of approx. 5k products. About 80% of these products were in our existing database but once we have installed the new database all the URLs will have changed. There is no quick way to match the old products with the new products so we would have to manually match all 5k products if we were were to setup 301 rules for the old products pointing to the new products. Of course this would take a lot of time. So the options are: 1. Is it worth putting in this effort to make the 301 rules? 2. Or are we okay just to delete the old product pages, let the SE see the 404 and just wait for it to index the new pages? 3. Or, as a compromise, should we 301 the old product page to the new category page as this is a lot quicker for us do do than redirecting to the new product page?

Trailing Slashes In Url use Canonical Url or 301 Redirect?
I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?
