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.

Htaccess - Redirecting TAG or Category pages
Hello Fellow Moz's, We have an issue redirecting some /TAG and /Category pages to inner pages. As an example we use: RedirectMatch 301 /category/Sample-Category(.*) https://OurDomain.com.au/New-Page//$1 That works well. The issue is we have other categories and tags that are named similar to /Sample-Category As an example, if we try to redirect /Sample-Category-1 to /New-Page-1 - it will not work, and redirects to /New-Page I assume this is because /Sample-Category is already being redirected, so anything after /Sample-Category like -1 or -2 or -3 etc, will not be recognized. Anyone know of a workaround?

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?

Ecommerce Site homepage , Is it okay to have Links as H2 Tags as that is relevant to the page ?
Hi All, I have a Rental site and I am bit confused with how best do my H Tags on my homepage I know the H1 is the most important, Then H2 Tags and so on.. and that these tags should really be titles for content. However, I have a few categories (links) on my homepage so I am wondering if I could put these as H2 Tags given that it is relevant to the page . H3 Tags will my News and Guides etc , H4 Tags will the whats on the footer. I am attached a made up screenshot of what I propose for my homepage if someone could please give it a quick look , it would be very much appreciated. I have looked at what some competitors do a lot of them don't seem to have h2's etc but I know it's an important factor for rankings etc. Many thanks Pete dJSFQwI

Does rel=canonical fix duplicate page titles?
I implemented rel=canonical on our pages which helped a lot, but my latest Moz crawl is still showing lots of duplicate page titles (2,000+). There are other ways to get to this page (depending on what feature you clicked, it will have a different URL) but will have the same page title. Does having rel=canonical in place fix the duplicate page title problem, or do I need to change something else? I was under the impression that the canonical tag would address this by telling the crawler which URL was the URL and the crawler would only use that one for the page title.

How Rel=Prev & Rel=Next work for me?
I have implemented Rel=Prev & Rel=Next tag on my website. I would like to give example URL to know more about it. http://www.vistapatioumbrellas.com/market-umbrellas?limit=40&p=3 http://www.vistapatioumbrellas.com/market-umbrellas?limit=40&p=4 http://www.vistapatioumbrellas.com/market-umbrellas?limit=40&p=5 Right now, I have blocked paginated pages by Robots.txt by following query. Disallow: /*?p= I have removed disallow syntax from Robots.txt for paginated pages. But, I have confusion with duplicate page title. If you will check all 3 pages so you will find out duplicate page title across all pages. I know that, duplicate page title is harmful for SEO. Will Google crawl + index all paginated pages? If yes so which page will get maximum benefits in organic ranking? Is there any specific way which may help me to solve this issue?

NOINDEX listing pages: Page 2, Page 3... etc?
Would it be beneficial to NOINDEX category listing pages except for the first page. For example on this site: http://flyawaysimulation.com/downloads/101/fsx-missions/ Has lots of pages such as Page 2, Page 3, Page 4... etc: http://www.google.com/search?q=site%3Aflyawaysimulation.com+fsx+missions Would there be any SEO benefit of NOINDEX on these pages? Of course, FOLLOW is default, so links would still be followed and juice applied. Your thoughts and suggestions are much appreciated.

How does a canonical work and is it necessary to also have a no index, follow tag in place?
Across our site, we have canonical tags in place for URLs that contain duplicate content and for URLs without a trailing slash since we are using URLs WITH a trailing slash for all URLs across our site. We also recently added a no index, follow tag to all non-canonical URLs since we noticed a high number of duplicate content URLs in Google Webmaster Tools. The first part of my question is: How does a canonical work? Does the robot read the canonical and immediately go to the canonical URL or does it continue to read past the canonical tag and get to the no index, follow tag if there is one present? The second part of my question is: Is it necessary to have both a canonical tag and no index, follow tag in place? Or should the canonical tag be sufficient to avoid duplicate content? And lastly, if both a canonical tag and no index, follow tag are in place, should they be in a specific order? Canonical tag first then no index, follow tag second or no index, follow tag first then canonical tag second? I would appreciate any insight you can give. Thank you!
