Rel=canonical for similar (not exact) content?
-
Hi all,
We have a software product and SEOMOZ tools are currently reporting duplicate content issues in the support section of the website.
This is because we keep several versions of our documentation covering the current version and previous 3-4 versions as well.
There is a fair amount of overlap in the documentation. When a new version comes out, we simply copy the documentation over, edit it as necessary to address changes and create new pages for the new functionality.
This means there is probably an 80% or so overlap from one version to the next. We were previously blocking Google (using robots.txt) from accessing previous versions of the sofware documentation, but this is obviously not ideal from an SEO perspective.
We're in the process of linking up all the old versions of the documenation to the newest version so we can use rel=canonical to point to the current version.
However, the content isn't all exact duplicates. Will we be penalized by Google because we're using rel=canonical on pages that aren't actually exact duplicates?
Thanks,
Darren.

Darren, nopes. You should be good doing this. You are essentially doing a 301 redirect and you are trying to tell that (current) page is the most important / most relevant page and that's the information/directive that Google is seeking from the Webmaster.
Just do it.

Set Canonical for Paginated Content
Hi Guys, This is a follow up on this thread: http://moz.com/community/q/dynamic-url-parameters-woocommerce-create-404-errors# I would like to know how I can set a canonical link in Wordpress/Woocommerce which points to "View All" on category pages on our webshop.
Technical SEO | | jeeyer
The categories on my website can be viewed as 24/48 or All products but because the quanity constantly changes viewing 24 or 48 products isn't always possible. To point Google in the right direction I want to let them know that "View All" is the best way to go.
I've read that Google's crawler tries to do this automatically but not sure if this is the case on on my website. Here is some more info on the issue: https://support.google.com/webmasters/answer/1663744?hl=en

Content relaunch without content duplication
We write great Content for blog and websites (or at least we try), especially blogs. Sometimes few of them may NOT get good responses/reach. It could be the content which is not interesting, or the title, or bad timing or even the language used. My question for the discussion is, what will you do if you find the content worth audience's attention missed it during its original launch. Is that fine to make the text and context better and relaunch it ? For example: 1. Rechristening the blog - Change Title to make it attractive

2. Add images
3. Check spelling
4. Do necessary rewrite, spell check
5. Change the timeline by adding more recent statistics, references to recent writeups (external and internal blogs for example), change anything that seems outdated Also, change title and set rel=cannoical / 301 permanent URLs. Will the above make the blog new? Any ideas and tips to do? Basically we like to refurbish (:-)) content that didn't succeed in the past and relaunch it to try again. If we do so will there be any issues with Google bots? (I hope redirection would solve this, But still I want to make sure) Thanks,0 -
Is this an ideal rel=canonical situation?
Hey Moz community, Thanks for taking time to answer my question. I'm working directly with a hospital that has several locations across the country. They've copied the same content over to each of their websites. Could I point the search engines back to a singular location (URL) using the rel=canonical tag? In addition, does the rel=canonical tag affect the search engine rankings of the URLs (about 13 of them) that use the rel=canonical tag? If I'm on track, is there an ideal URL (location) to decide has the original content? This is actually the first time I've ever needed to use rel=canonical (if applicable). Thanks so much. Cole

Duplication, pagination and the canonical
Hi all, and thank you in advance for your assistance. We have an issue of paginated pages being seen as duplicates by pro.moz crawlers. The paginated pages do have duplicated by content, but are not duplicates of each other. Rather they pull through a summary of the product descriptions from other landing pages on the site. I was planing to use rel=canonical to deal with them, however I am concerned as the paginated pages are not identical to each other, but do feature their own set of duplicate content! We have a similar issue with pages that are not paginated but feature tabs that alter the URL parameters like so: ?st=BlueWidgets ?st=RedSocks ?st=Offers These are being seen as duplicates of the main URL, and again all feature duplicate content pulled from elsewhere in the site, but are not duplicates of each other. Would a canonical tag be suitable here? Many Thanks

Canonical and 301
Hi We have recently restructured our site and 301 redirected some pages. Unfortunately the new page which we 301 to, still had the canonical tags pointing to the old pages. Would this cause google not to index the new pages....?????

The Bible and Duplicate Content
We have our complete set of scriptures online, including the Bible at http://lds.org/scriptures. Users can browse to any of the volumes of scriptures. We've improved the user experience by allowing users to link to specific verses in context which will scroll to and highlight the linked verse. However, this creates a significant amount of duplicate content. For example, these links: http://lds.org/scriptures/nt/james/1.5 http://lds.org/scriptures/nt/james/1.5-10 http://lds.org/scriptures/nt/james/1 All of those will link to the same chapter in the book of James, yet the first two will highlight the verse 5 and verses 5-10 respectively. This is a good user experience because in other sections of our site and on blogs throughout the world webmasters link to specific verses so the reader can see the verse in context of the rest of the chapter. Another bible site has separate html pages for each verse individually and tends to outrank us because of this (and possibly some other reasons) for long tail chapter/verse queries. However, our tests indicated that the current version is preferred by users. We have a sitemap ready to publish which includes a URL for every chapter/verse. We hope this will improve indexing of some of the more popular verses. However, Googlebot is going to see some duplicate content as it crawls that sitemap! So the question is: is the sitemap a good idea realizing that we can't revert back to including each chapter/verse on its own unique page? We are also going to recommend that we create unique titles for each of the verses and pass a portion of the text from the verse into the meta description. Will this perhaps be enough to satisfy Googlebot that the pages are in fact unique? They certainly are from a user perspective. Thanks all for taking the time!

Canonical pagination content
Hello We have a large ecommerce site, as you are aware that ecommerce sites has canonical issues, I have read various sources on how best to practice canonical on ecommerce site but I am not sure yet.. My concert is pagination where I am on category product listing page.. the pagination will have all different product not same however the meta data will be same so should I make let's say page 2 or 3 to main category page or keep them as is to index those pages? Another issue is using filters, where I am on any page and I filter by price or manufacturer basically the page will be same so here It seems issue of duplicate content, so should I canonical to category page only for those result types? So basically If I let google crawl my pagination content and I only canonical those coming with filter search result that would be best practice? and would google webmaster parameter handling case would be helpful in this scenario ? Please feel free to ask in case you have any queries regards
