          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!

                    What to do with old content after 301 redirect

                    I'm going through all our blog and FAQ pages to see which ones are performing well and which ones are competing with one another. Basically doing an SEO content clean up. Is there any SEO benefit to keeping the page published vs trashing it after you apply a 301 redirect to a better performing page?

                    Help Setting Up 301 Redirects from Coldfusion Site to Wordpress Site.

                    I have created a new website and need to redirect all of the previous pages to the new one. The old website was built in coldfusion and the new site is built in wordpress. One of the pages I'm trying to redirect is www.norriseal.com/products.cfm to http://norrisealwellmark.com/products/. This is what I have in my .htaccess file <ifmodule mod_rewrite.c="">Options +FollowSymlinks
                    RewriteEngine On
                    RewriteBase /
                    Redirect 301 /products.cfm http://norrisealwellmark.com/products/</ifmodule> The result of this redirect is http://norrisealwellmark.com/products.cfm How do I prevent the .cfm from appending to the destination URL?

                    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

                    CNAME vs 301 redirect

                    Hi all, Recently I created a website for a new client and my next job is trying to get them higher in Google. I added them in OSE and noticed some strange backlinks. To my surprise the client has about 20 domain names. All automatically poiting to (showing) the same new mainsite now. www.maindomain.nl www.maindomain.be
                    www.maindomain.eu
                    www.maindomain.com
                    www.otherdomain.nl
                    www.otherdomain.com
                    ... Some of these domains have backlinks too (but not so much). I suggested to 301 redirect them all to the main site. Just to avoid duplicate content. But now the webhoster comes into play: "It's a problem, client has only 1 hosting account, blablabla...". They told me they could CNAME the 20 domains to the main domain. Or A-record them to an IP address. This is too technical stuff for me. So my concrete questions are: Is it smart to do anything at all or am I just harming my client? The main site is ranking pretty well now. And some backlinks are from their copy sites (probably because everywhere the logo links to the full mainsite url). Does the CNAME or A-record solution has the same effect as a 301 redirect, from SEO perspective? Many thanks,
                    Hans

                    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

                    Hreflang on non-canonical pages

                    Hi! I've been trying to figure out what is the best way to solve this dilemma with duplicate content and multiple languages across domains. 1 product info page 2 same product but GREEN
                    3 same product but RED
                    4 same product but YELLOW **Question: ** Since pages 2,3,4 just varies slightly I use the canonical tag to indicate they are duplicates of page 1. Now I also want to indicate there are other language versions with the_ rel="alternate" hreflang="x" _element. Should I place the _rel="alternate" hreflang="x" _on the canonical page only pointing to the canonical page with "x" language. Should I place the _rel="alternate" hreflang="x" _on all pages pointing to the canonical page with the "x" language? Should I place the _rel="alternate" hreflang="x"  _on all pages and then point it to the translated page (even if it is not a canonical page) ? /Lars

                    Drupal URL Aliases vs 301 Redirects + Do URL Aliases create duplicates?

                    Hi all! I have just begun work on a Drupal site which heavily uses the URL Aliases feature. I fear that it is creating duplicate links. For example:: we have http://www.URL.com/index.php and http://www.URL.com/ In addition we are about to switch a lot of links and want to keep the search engine benefit. Am I right in thinking URL aliases change the URL, while leaving the old URL live and without creating search engine friendly redirects such as 301s? Thanks for any help! Christian

                    301 Redirect vs Domain Alias

                    We have hundreds of domains which are either alternate spelling of our primary domain or close keyword names we didn't want our competitor to get before us. The primary domain is running on a dedicated Windows server running IIS6 and set to a static IP. Since it is a static IP and not using host headers any domain pointed to the static IP will immediately show the contents of the site, however the domain will be whatever was typed. Which could be the primary domain or an alias. Two concerns. First, is it possible that Google would penalize us for the alias domains or dilute our primary domain "juice"? Second, we need to properly track traffic from the alias domains. We could make unique content for those performing well and sell or let expire those that are sending no traffic. It's not my goal to use the alias domains to artificially pump up our primary domain. We have them for spelling errors and direct traffic. What is the best practice for handling one or both of these issues?
