      I have an interesting situation.

      Current URLs Example1:

      www.domain.com/red-widgets-cid-1234.html
      www.domain.com/red-widgets-cid-1234-1.html
      www.domain.com/red-widgets-cid-1234-1-1.html

      Canonical on All Above URLs:
      www.domain.com/red-widgets-cid-1234.html

      New URL:
      www.domain.com/red-widgets-cid-4567.html

      Current URLs Example2:

      www.domain.com/red-widgets-cid-1234+10.html
      www.domain.com/red-widgets-cid-1234+10-1.html
      www.domain.com/red-widgets-cid-1234+10-1-1.html

      Canonical on All Above URLs:
      www.domain.com/red-widgets-cid-1234+10.html

      New URL:
      www.domain.com/red-widgets-cid-6789.html

      Current URLs Example3:

      www.domain.com/red-widgets-cid-1234+10+5.html
      www.domain.com/red-widgets-cid-1234+10+5-1.html
      www.domain.com/red-widgets-cid-1234+10+5-1-1.html

      Canonical on All Above URLs:
      www.domain.com/red-widgets-cid-1234+10+5.html

      New URL:
      www.domain.com/american-red-widgets-cid-6789+5.html

      I want to make sure all variations of the above URL redirect to the new URLs.  However, as you see in Example 3, we are dealing with variables that are passed on. (+5 in this case).

      Question 1: What wildcard 301 redirect / regular expression can I use to tackle these ?

      Question 2: If we redirect www.domain.com/red-widgets-cid-1234+10+5.html to www.domain.com/red-widgets-cid-6789+5.html and www.domain.com/red-widgets-cid-6789+5.html contains the canonical tag www.domain.com/american-red-widgets-cid-6789+5.html, any concerns or red flags here ?

        Hi Nakul

        Here is my stab at question 1, my methodology is trial and error so if any guru's want to take another shot at it please do so. Here is a nice 301 reference page lots of examples

        RewriteEngine On
        RewriteRule ^(.)_red-widgets-cid-1234.html$ www.domain.com/red-widgets-cid-4567.html [R=301]
        #Example 2
        RewriteRule ^(.
        )_red-widgets-cid-1234+10.html$ www.domain.com/red-widgets-cid-6789.html [R=301]
        #Example 3
        RewriteRule ^(.*)_red-widgets-cid-1234+10+5.html$ www.domain.com/american-red-widgets-cid-6789+5.html [R=301,L]

        We use ^ to denote start of string

        We use $ to denote end of string

        We use (.*)_ to look for a keyword. In the examples above we are looking for what each page name has in common

        We use [R=301,L] for the Last rewrite, previous rules just use [R=301]

        One thing that (maybe) needed is escaping the +signs in the string so like example 3 would be

        ^(.*)_red-widgets-cid-1234+10+5.html$ www.domain.com/american-red-widgets-cid-6789+5.html

        Also I may missed a wildcard on some of these....

        ^(.)_red-widgets-cid-1234+10+5(.).html$ www.domain.com/american-red-widgets-cid-6789+5.html

        Question 2:

        Canonical to self canonical tag is okay.
        This = That and That = That ..........Okay
        This = That and That = The ..........Not Okay

        Hope that puts you on track

          Canonical and Alternate Advice

          At the moment for most of our sites, we have both a desktop and mobile version of our sites. They both show the same content and use the same URL structure as each other. The server determines whether if you're visiting from either device and displays the relevant version of the site. We are in a predicament of how to properly use the canonical and alternate rel tags. Currently we have a canonical on mobile and alternate on desktop, both of which have the same URL because both mobile and desktop use the same as explained in the first paragraph. Would the way of us doing it at the moment be correct?

          Move to new domain using Canonical Tag

          At the moment, I am moving from olddomain.com (niche site) to the newdomain.com (multi-niche site). Due to some reasons, I do not want to use 301 right now and planning to use the canonical pointing to the new domain instead. Would Google rank the new site instead of the old site? From what I have learnt, the canonical tag lets Google know that which is the main source of the contents. Thank you very much!

          Googlebot being redirected but not users?

          Hi, We seem to have a slightly odd issue. We noticed that a number of our location category pages were slipping off 1 page, and onto page 2 in our niche. On inspection, we noticed that our Arizona page had started ranking in place of a number of other location pages - Cali, Idaho, NJ etc. Weirdly, the pages they had replaced were no longer indexed, and would remain so, despite being fetched, tweeted etc. One test was to see when the dropped out pages had been last crawled, or at least cached. When conducting the 'cache:domain.com/category/location' on these pages, we were getting 301 redirected to, you guessed it, the Arizona page. Very odd. However, the dropped out pages were serving 200 OK when run through header checker tools, screaming frog etc. On the face of it, it would seem Googlebot is getting redirected when it is hitting a number of our key location pages, but users are not. Has anyone experienced anything like this? The theming of the pages are quite different in terms of content, meta etc. Thanks.

          Canonical tag + HREFLANG vs NOINDEX: Redundant?

          Hi, We launched our new site back in Sept 2013 and to control indexation and traffic, etc we only allowed the search engines to index single dimension pages such as just category, brand or collection but never both like category + brand, brand + collection or collection + catergory We are now opening indexing to double faceted page like category + brand and the new tag structure would be: For any other facet we're including a "noindex, follow" meta tag. 1. My question is if we're including a "noindex, follow" tag to select pages do we need to include a canonical or hreflang tag afterall? Should we include it either way for when we want to remove the "noindex"? 2. Is the x-default redundant? Thanks for any input. Cheers WMCA

For example, my site as at www.site.com , but the non cannocail is at site.com is their any way to set thet up without actually edting it at site.com ? Thanks for your help

          Multiple 301 Redirects for the Same Page

          Hi Mozzers, What happens if I have a trail of 301 redirects for the same page? For example,
          SiteA.com/10 --> SiteA.com/11 --> SiteA.com/13 --> SiteA.com/14 I know I lose a little bit of link juice by 301 redirecting.
          The question is, would the link juice look like this for the example above? 100% --> 90% --> 81% -->72.9%
          Or just 100% -----------------------------------------> 90% Does this link juice refer to juice from inbound links or links between internal pages on my site? Thanks!

          Canonical VS Rel=Next & Rel=Prev for Paginated Pages

          I run an ecommerce site that paginates product pages within Categories/Sub-Categories. Currently, products are not displayed in multiple categories but this will most likely happen as time goes on (in Clearance and Manufacturer Categories). I am unclear as to the proper implementation of Canonical tags and Rel=Next & Rel=Prev tags on paginated pages. I do not have a View All page to use as the Canonical URL so that is not an option. I want to avoid duplicate content issues down the road when products are displayed in multiple categories of the site and have Search Engines index paginated pages. My question is, should I use the Rel=Next & Rel=Prev tags on paginated pages as well as using Page One as the Canonical URL? Also, should I implement the Canonical tag on pages that are not yet paginated (only one page)?

          Canonical & noindex? Use together

          For duplicate pages created by the "print" function, seomoz says its better to use noindex (http://www.seomoz.org/blog/complete-guide-to-rel-canonical-how-to-and-why-not) and JohnMu says its better to use canonical http://www.google.com/support/forum/p/Webmasters/thread?tid=6c18b666a552585d&hl=en What do you think?
