Using a canonical tag to eliminate ID variables?
-
My research on seomoz has resulted in conflicting ideas regarding the canonical tag. One article says avoid it, the other says embrace it.
We have fixed a majority of our architecture problems using redirects for duplicate content, however, when we send out newsletters we still have these pesky tracking ids. I figured out how to remove them from analytics, but am unsure of how this affects our SEO. An example of one of our links is: https://www.quicklearn.com/transcript/?utm_source=news101011&utm_medium=e&utm_campaign=newclass&nlid=news101011&UID=2287
The original url being www.quicklearn.com/transcript/ the custom (non-Google) variables being nlid and uid.
Is this a problem? Do I need rel cononical tags on each and every page?

Are these links on your web site or are they in a newsletter sent out via email?
anyhow, there is nothing wrong with the canonical tag, if its used for the right reasons, but often a 301 redirect is better.
Not understanding your situation fuilly, my advice is.
first, will a 301 do the job?
if not can i use a canonical

Shopify Canonicals for Tagged Filters
I've been researching this topic endlessly and thought I had arrived at a solution but Screaming Frog indicates my solution was not successful. Problem: I used tags to filter my collections pages. The result, I discovered, was the creation of dozens and dozens, maybe hundreds, of additional collection URLs for each possible permutation of tag filters. I would like to make the collection page URL, with no tag filters, the canonical. Proposed Solution: I found the following code described somewhere as the solution: {% if template contains 'collection' and current_tags %} {% else %} {% endif %} However, I crawled my site with Screaming Frog and found that the canonical link element is still listed as the URL with the tags included. The crawler does recognizes the "noindex" instruction. Any ideas on what the best move is here?

301 redirect: canonical or non canonical?
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.

Is it appropriate to use canonical for a yearly post with similar content?
I've begun writing an annual review of local business directories. Post from 2012 is here: http://web.servicecrowd.com.au/blog/top-10-australian-business-directories-in-2012/ New 2014 post is here: http://web.servicecrowd.com.au/blog/top-10-australian-business-directories-2014/ Is this appropriate use? Next year the post will be similar, but different metrics reported and slightly different review. Side note: For some reason the post hasn't been indexed by Google yet. Usually new posts are indexed as soon as they are shared on social media.

Is it a good idea to use the rel canonical tag to refer to the original source?
Sometimes we place our blog post also on a external site. In this case this post is duplicated. Via the post we link to the original source but is it also possible to use the rel canonical tag on the external site? For example: The original blogpost is published on http://www.original.com/post The same blogpost is published on http:///www.duplicate.com/post. In this case is it wise to put a rel canonical on http://www.duplicate.com/post like this: ? What do you think? Thanks for help! Robert

Duplicate canonical URLs in WordPress
Hi everyone, I'm driving myself insane trying to figure this one out and am hoping someone has more technical chops than I do. Here's the situation... I'm getting duplicate canonical tags on my pages and posts, one is inside of the WordPress SEO (plugin) commented section, and the other is elsewhere in the header. I am running the latest version of WordPress 3.1.3 and the Genesis framework. After doing some testing and adding the following filters to my functions.php: <code>remove_action('wp_head', 'genesis_canonical'); remove_action('wp_head', 'rel_canonical');</code> ... what I get is this: With the plugin active + NO "remove action" - duplicate canonical tags

With the plugin disabled + NO "remove action" - a single canonical tag
With the plugin disabled + A "remove action" - no canonical tag I have tried using only one of these remove_actions at a time, and then combining them both. Regardless, as long as I have the plugin active I get duplicate canonical tags. Is this a bug in the plugin, perhaps somehow enabling the canonical functionality of WordPress? Thanks for your help everyone. Robert Dempsey0
