Rel=canonical tag on original page?
-
Afternoon All,
We are using Concrete5 as our CMS system, we are due to change but for the moment we have to play with what we have got. Part of the C5 system allows us to attribute our main page into other categories, via a page alaiser add-on. But what it also does is create several url paths and duplicate pages depending on how many times we take the original page and reference it in other categories. We have tried C5 canonical/SEO add-on's but they all seem to fall short.We have tried to address this issue in the most efficient way possible by using the rel=canonical tag. The only issue is the limitations of our cms system. We add the canonical tag to the original page header and this will automatically place this tag on all the duplicate pages and in turn fix the problem of duplicate content. The only problem is the canonical tag is on the original page as well, but it is referencing itself, effectively creating a tagging circle. Does anyone foresee a problem with the canonical tag being on the original page but in turn referencing itself?
What we have done is try to simplify our duplicate content issues. We have over 2500 duplicate page issues because of this aliasing add-on and want to automate the canonical tag addition, rather than go to each individual page and manually add this tag, so the original reference page can remain the original.
We have implemented this tag on one page at the moment with 9 duplicate pages/url's and are monitoring, but was curious if people had experienced this before or had any thoughts?

My experience matches Nakul's. Technically, Bing claims you shouldn't have canonicals on the canonical page itself, but I've never seen evidence that they actually do anything about that or don't honor the tags. I think they just don't like processing the extra tags. Google originally suggested the same thing, but then softened their stance. I've NEVER seen a practical issue with it on Google.
So, by the book, Bing would rather you only put it on non-canonical URLs. Practically, though, it seems to work absolutely fine. I wouldn't lose sleep over it. So many big sites are doing this now that I don't think the engines can devalue the tactic. It's not spammy - it's just mildly inconvenient for them (some extra processing).

I implemented the canonical tag last year in a similar situation and yes, it's on the original page as well. No issues. Look at eBay.com, they also have canonical tags on all pages including the original page.
I have not seen/encountered any issues. Now when I go check the cache for http://www.example.com/duplicate-url-3.html which has a canonical tag referring to the original-url, Google shows me the canonical URL. The duplicate pages literally disappear from the SERPS, because essentially its like a 301 redirect.

Landing pages for paid traffic and the use of noindex vs canonical
A client of mine has a lot of differentiated landing pages with only a few changes on each, but with the same intent and goal as the generic version. The generic version of the landing page is included in navigation, sitemap and is indexed on Google. The purpose of the differentiated landing pages is to include the city and some minor changes in the text/imagery to best fit the Adwords text. Other than that, the intent and purpose of the pages are the same as the main / generic page. They are not to be indexed, nor am I trying to have hidden pages linking to the generic and indexed one (I'm not going the blackhat way). So – I want to avoid that the duplicate landing pages are being indexed (obviously), but I'm not sure if I should use noindex (nofollow as well?) or rel=canonical, since these landing pages are localized campaign versions of the generic page with more or less only paid traffic to them. I don't want to be accidentally penalized, but I still need the generic / main page to rank as high as possible... What would be your recommendation on this issue?

Redirecting homepage to internal page (2nd Tier page)
We are planning to experiment redirecting our homepage to one of the 2nd tier page. I mean....example.com to example.com/page. We need this page to rank well, but it doesn't have much internal links or external back-links, so we opt for this redirect. Advantage with this page is, it has "keyword" we want to rank for in URL. "page" in example.com/page. Will this help or hurt us in SEO? I think we are missing keyword in our root domain, so interested to highlight this page. Thanks, Satish

Fast/Easy Way to Implement Canonical tags in Bulk in Magento CMS?
Hello Amazing SEO Community! Quick Q for a client with a TON of duplicate content. (yikes!) My client is currently undertaking a large SEO project around canonical tagging for their thousands of duplicate pages. Currently, one product sits on multiple URLs and they are being indexed as different pages (with the same content). The issue is found across all products and other pages, and across their international sites as well. One core challenge they face now is lack of time/resources from their developer side. The solution we see to the duplicate content is to manually add a canonical tag to each of our tens of thousands of pages. Their content management system is Magento. Has anyone ever tackled canonicalization for a large site that uses Magento? Any more efficient solutions to manual tagging is ideal. Thanks in advance for your input. -Bonnie

Canonical tag - but Title and Description are slightly different
I am building a new SEO site with a "Silo" / Themed architecture. I have a travel website selling hotel reservations. I list a hotel page under a city page - example, www.abc.com/Dallas/Hilton.html Then I use that same property under a segment within the city - example www.abc.com/Dallas/Downtown/Hilton.html, so there are two URLs with the same content Both pages are identical, except I want to customize the Title and Description. I want to customize the title and description to build a consistent theme - for example the /Downtown/Hilton page will have the words "Near Downtown" in the Title and Description, while the primary city Hilton page will not. So I have two questions about this. First, is it okay to use a canonical tag if the Title and Description are slightly different? Everything else is identical. If so, will Google crawl and comprehend the unique Title and Description on the "Downtown" silo? I want Google to see that I have several "supporting" pages to my main landing page(s). I want to present to Google 5 supporting pages in each silo that each has a supporting keyword theme. But I'm not sure if Google will consider content of pages that point to a different page using the canonical tag. Please see this supporting example: http://d.pr/i/aQPv Thanks for your insights. Rob

Yoast & rel canonical for paginated Wordpress URLs
Hello, our Wordpress blog at http://www.jobs.ca/career-resources has a rel canonical issue since we added pagination to the front page and category-pages. We're using Yoast and it's incorrectly applying a rel-canonical meta tag referencing page 1 on page 2, 3, etc. This is a known misuse of the rel-canonical tag (per Google's Webmaster Blog - http://googlewebmastercentral.blogspot.ca/2013/04/5-common-mistakes-with-relcanonical.html, which says rel-canonical should be replaced with rel-prev and rel-next for page 2, 3, etc.). We don't see a way to specify anywhere in Yoast's options to correct this behaviour for page 2, 3, etc. Yoast allows you to override a page's canonical URL, otherwise it automatically uses the Wordpress permalink. My question is, does anyone know how to configure Yoast to properly replace rel-canonical tags with rel-prev and rel-next for paginated URLs, or do I need to look at another plugin or customize the behavior directly in my child theme code? This issue was brought up here as well: http://moz.com/community/q/canonical-help, but the only response did not relate to Yoast. (We're using Wordpress 3.6.1 and Yoast "Wordpress SEO" 1.4.18)

Dynamic pages - ecommerce product pages
Hi guys, Before I dive into my question, let me give you some background.. I manage an ecommerce site and we're got thousands of product pages. The pages contain dynamic blocks and information in these blocks are fed by another system. So in a nutshell, our product team enters the data in a software and boom, the information is generated in these page blocks. But that's not all, these pages then redirect to a duplicate version with a custom URL. This is cached and this is what the end user sees. This was done to speed up load, rather than the system generate a dynamic page on the fly, the cache page is loaded and the user sees it super fast. Another benefit happened as well, after going live with the cached pages, they started getting indexed and ranking in Google. The problem is that, the redirect to the duplicate cached page isn't a permanent one, it's a meta refresh, a 302 that happens in a second. So yeah, I've got 302s kicking about. The development team can set up 301 but then there won't be any caching, pages will just load dynamically. Google records pages that are cached but does it cache a dynamic page though? Without a cached page, I'm wondering if I would drop in traffic. The view source might just show a list of dynamic blocks, no content! How would you tackle this? I've already setup canonical tags on the cached pages but removing cache.. Thanks
