      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!

                How effective are 301 redirects in passing page rank?

                301 redirect page rank

                I have a blog which is ranking well for certain terms, and would like to repurpose it to better explain these terms it is ranking for, including updating the url to the new term the blog will be about. The plan being to 301 redirect the old url to new. In the past, I've done this with other pages, and have actually lost much of the rankings that I had earned on the original URL. What is your take on this? Maybe repurpose blog, but maintain original URL just to be on the safe side? Thanks

                Soft 404's on a 301 Redirect...Why?

                So we launched a site about a month ago. Our old site had an extensive library of health content that went away with the relaunch. We redirected this entire section of the site to the new education materials, but we've yet to see this reflected in the index or in GWT. In fact, we're getting close to 500 soft 404's in GWT. Our development team confirmed for me that the 301 redirect is configured correctly. Is it just a waiting game at this point or is there something I might be missing? Any help is appreciated. Thanks!

                Updating inbound links vs. 301 redirecting the page they link to

                Hi everyone, I'm preparing myself for a website redesign and finding conflicting information about inbound links and 301 redirects. If I have a URL (we'll say website.com/website) that is linked to by outside sources, should I get those outside sources to update their links when I change the URL to website.com/webpage? Or is it just as effective from a link juice perspective to simply 301 redirect the old page to the new page? Are there any other implications to this choice that I may want to consider? Thanks!

                Redirect URLS with 301 twice

                Hello, I had asked my client to ask her web developer to move to a more simplified URL structure. There was a folder called "home" after the root which served no purpose. I asked for the URLs to be redirected using 301 to the new URLs which did not have this structure. However, the web developer didn't agree and decided to just rename the "home" folder "p". I don't know why he did this. We argued the case and he then created the URL structure we wanted. Initially he had 301 redirected the old URLS (the one with "Home") to his new version (the one with the "p"). When we asked for the more simplified URL after arguing, he just redirected all the "p" URLS to the PAGE NOT FOUND.  However, remember, all the original URLs are now being redirected to the PAGE NOT FOUND as a result. The problems I see are these unless he redirects again: The new simplified URLS  have to start from scratch to rank 2)We have duplicated content - two URLs with the same content Customers clicking products in the SERPs will currently find that they are being redirect to the 404 page. I understand that redirection has to occur but my questions are these: Is it ok to redirect twice with 301 - so old URL to the  "p" version then to final simplified version. Will link juice be lost doing this twice? If he redirects from the original URLS to the final version missing out the "p" version, what should happen to the "p" version - they are currently indexed. Any help would be appreciated. Thanks

                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?

                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?

                301 Redirect & Cloaking

                HEllo~~~~ People. I have a question regarding on cloaking. I will be really greatful if you can help me with question. I have a site www.example.com and it is targeting for multi countries. So I use sub directories for targeting multi countries. e.g. www.example.com/us/ www.example.com/de/ www.example.com/hk/ ....... so on and on. Therefore, when people type www.example.com, I use IP delivery to send users to each coutries. Here is my question. I use 301 redirect for IP delivery, which means when user enter www.example.com, my site read user's IP and send them to right country site by 301 redirect. In this case, is there any possibility that Google considers it as cloaking? Please people.... share me some ideas and thoughs.
