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!

Robots txt. in page with 301 redirect
We currently have a a series of help pages that we would like to disallow from our robots txt. The thing is that these help pages are located in our old website, which now has a 301 redirect to current site. Which is the proper way to go around? 1- Add the pages we want to disallow to the robots.txt of the new website? 2- Break the redirect momentarily and add the pages to the robots.txt of the old one? 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

Changing title tags, do we need 301 redirects
I found many duplicate title tags and I'm in the process of changing it Do I need 301 redirects in place when I switch it? I am only changing the title tag. Also, we are switching over to a new site very soon, I am worried that we might be using too many 301 redirect "hops" because we are doing a lot of optimization as well. (video from matt cutts describing 301 redirects and hops: http://www.youtube.com/watch?v=r1lVPrYoBkA. Does anyone have any experience in doing too many redirect hops that it affected your rankings? Any good ideas to avoid this?

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

Can I remove 301 redirects after some time?
Hello, We have an very large number of 301 redirects on our site and would like to find a way to remove some of them. Is there a time frame after which Google does not need a 301 any more? For example if A is 301 redirected to B, does Google know after a while not to serve A any more, and replaces any requests for A with B? How about any links that go to A? Or: Is the only option to have all links that pointed to A point to B and then the 301 can be removed after some time? Thank you for you you help!

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?

Where does Wordpress store the 301 redirects?
Hi, I've just created a campaign for my new wordpress blog and found 11 301 redirects which I was not aware of. It looks like wordpress has created them automatically. Does any one know how wordpress handles this issues or where are they stored so I can delete them? They are of no use for me. 9 of these redirects point to the same url with an added '/' and are in pages 1 is on a post. I've been changing the permalink and some urls several times and maybe one of these times the Wordpress has automatically created the 301 redirect. But why? I do not want to keep the old url. the last redirect is very strange it goes from http://www.mydomain.com/folder to http://www.mydomain.com where folder is the folder where I installed wordpress. But again, I want no one to type the url with the folder name or even know this folder exists. Any comment on this would be greatly appreciated. Thanks a lot, David
