      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!

                Proper 301 redirect code for http to https

                I see lots of suggestions on the web for forwarding http to https.  I've got several existing sites that want to take advantage of the SSL boost for SEO (however slight) and I don't want to lose SEO placements in the process.  I can force all pages to be viewed through the SSL - that's no problem.  But for SEO reasons, do I need to do a 301 redirect line of code for every page in the site to the new "https" version?  Or is there a way to catch all with one line of code that Google, etc. will recognize & honor?

                How to redirect 302 status to 301 status code using wordpress

                I just ran the link opportunity option within site explorer and it shows that 31 pages are currently in a 302 status.  Should I try to convert the 302's to 301's?  And what is the easiest way to do this? I see several wordpress plugins that claim to do 301 redirects but I don't know which to choose. Any help would be greatly appreciated!

                301 Redirects Relating to Your XML Sitemap

                Lets say you've got a website and it had quite a few pages that for lack of a better term were like an infomercial, 6-8 pages of slightly different topics all essentially saying the same thing.  You could all but call it spam. www.site.com/page-1 www.site.com/page-2 www.site.com/page-3 www.site.com/page-4 www.site.com/page-5 www.site.com/page-6 Now you decided to consolidate all of that information into one well written page, and while the previous pages may have been a bit spammy they did indeed have SOME juice to pass through. Your new page is: www.site.com/not-spammy-page You then 301 redirect the previous 'spammy' pages to the new page.  Now the question, do I immediately re-submit an updated xml sitemap to Google, which would NOT contain all of the old URL's, thus making me assume Google would miss the 301 redirect/seo juice.  Or do I wait a week or two, allow Google to re-crawl the site and see the existing 301's and once they've taken notice of the changes submit an updated sitemap? Probably a stupid question I understand, but I want to ensure I'm following the best practices given the situation, thanks guys and girls!

                301 redirect relative or absolute path?

                Hello everyone, Recently we've changed the URL structure on our website, and of course we had to 301 redirect the old urls to the coresponding new ones. The way the technical guys did this is: "http://www.domain.com/old-url.html" 301 redirect to "/new-url.html"
                meaning as a relative redirect path, not an absolute one like this:
                "http://www.domain.com/old-url.html" 301 redirect to "http://www.domain.com/new-url.html" This happened for few thousands urls, and the fact is the organic traffic dropped for those pages after this change. (no other changes were made on these pages and the new urls are as seo friendly as possible, A grade on On-Page Grader). The question is: does the relative redirect negatively affects seo, or it counts the same as an absolute path redirect? Thanks,
                S.

                Switching from a .org to .io (301 domain redirect)

                I'm considering switching my main site from a .org to .io address; the .org is an exact match domain which helped to kickstart it a few years ago and now has about 50% repeat visitors, but was thrown off the Apple affiliation program for trademark infringement. I've found and purchased a nice (non-infringing) .io domain, and I've read the advice here on how to properly 301 the old domain; but my question is - does it matter that it's .io? Is this going to significantly hurt my rankings, even when everything has been 301'd properly? Another thought I had is that I may actually come out better off in the long run, what with Google penalties being applied to exact match domains. Is this a ranking suicide? If so, I'm tempted to leave it as is; even without the affiliation, it's making a good amount every month in ad fees that I don't want to disrupt. Thanks all!

                Delete 301 redirected pages from server after redirect is in place?

                Should I remove the redirected old pages from my site after the redirects are in place? Google is hating the redirects and we have tanked. I did over 50 redirects this week, consolidating content and making one great page our of 3-10 pages with very little content per page. But the old pages are still visible to google's bot. Also, I have not put a rel canonical to itself on the new pages. Is that necessary? Thanks! Jean

                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?

                Redirect non-www if using canonical url?

                I have setup my website to use canonical urls on each page to point to the page i wish Google to refer to. At the moment, my non-www domain name is not redirected to www domain. Is this required if i have setup the canonical urls? This is the tag i have on my index.php page rel="canonical" href="http://www.mydomain.com.au" /> If i browse to http://mydomain.com.au should the link juice pass to http://www.armourbackups.com.au? Will this solve duplicate content problems? Thanks
