ECommerce Site, URL's, Canonical and Tracking Referral Traffic
-
I'm very, very new to eCommerce websites that employ many different URL's to track referral traffic. I have a client that has 18 different URL's that land on the Home Page in order to track traffic from different referral sources. For example:
http://erasedisease.com/?ref=abot - Tracks traffic from an affiliate source
http://erasedisease.com/?ref=FB01 - Tracks traffic from a FB Ad
http://erasedisease.com/?ref=sas&SSAID=289169 - Tracks more affiliate traffic
...and the list goes on and on.
My first question is do you think this could hinder our Google rankings? SEOMoz Crawl doesn't show any Duplicate Content Errors, so I guess that's good. I've just been reading a lot about Canonical Url's and eCommerce sites, but I'm not sure if this is a situation where I'd want to use some kind of canonical plugin for this Wordpress website or not.
Any advice would be greatly appreciated. Thanks so much!!

Thank you so much guys! This information is incredibly helpful, and easy to transfer over to the client being that it's coming from experts. Thanks again!

To answer your 1st question: Yes you are going to have duplicate content issues. SEOmoz won't catch everything especially if you don't put those URLs in a sitemap where they can access it.
Your client is doing it ALL WRONG!
Install Google Analytics. Use the Google Anaytics URL Builder : http://support.google.com/googleanalytics/bin/answer.py?hl=en&answer=55578
Log in to GA and go to Traffic Sources > Campaigns.
I just created one for you: http://www.erasedisease.com/?utm_source=SEOmoz&utm_medium=QandA&utm_campaign=Francisco_Meza_affiliate . Click it and you'll see it populate in GA in a day or two. It'll make sense once you see it in action. Basically you are creating URLs to track campaigns from affiliates. Now you will NEVER have duplicate content issues.

You definitely need to use a canonical tag to handle tracking URLs. If you're on WordPress I highly recommend using Yoast's SEO Plugin - not only for canonicals, but everything.
You can also handle tracking URLs within Google Webmaster Tools.

What could cause Google to not honor canonical URLs?
I have a strange situation on a website, when I do a Google query of site:example.com all the top indexed results appear to be queries that users can perform on the website. So any random term the user searches for on the website for some reason is causing the search result page to get indexed - like example.com/search/query/random-keywords However, the search results page has a canonical tag on it that points to example.com/search, but that doesn't seem to be doing anything. Any thoughts or ideas why this could be happening?

Community Discussion - What's been your experience with accessibility?
When Laura Lippay came to me with the idea to write a series of posts on the Moz blog about SEO and accessibility, it really got my gears turning. As the blog manager, I realized I'd been thinking about all sorts of ways to make the blog the best it can be, but accessibility was one place I had yet to explore in-depth. While I have my own goals and projects around this topic churning along in the background, I'd love to hear what the community's done to be inclusive to all users of the Internet. What've you struggled with in terms of making sites you've worked on accessible -- both technically and as an initiative in general? What's often missing that you've become passionate about including? Do you have any big wins you're especially proud of and want to share? Looking forward to reading your thoughts and stories, folks! 🙂

Why can't I redirect 302 errors to 301's?
I've been advised by IT that due to the structure of our website (they don't use sub-folders) it's not possible to change 302's to 301's. Is this correct, or am I being fobbed off?

How to Remove /feed URLs from Google's Index
Hey everyone, I have an issue with RSS /feed URLs being indexed by Google for some of our Wordpress sites. Have a look at this Google query, and click to show omitted search results. You'll see we have 500+ /feed URLs indexed by Google, for our many category pages/etc. Here is one of the example URLs: http://www.howdesign.com/design-creativity/fonts-typography/letterforms/attachment/gilhelveticatrade/feed/. Based on this content/code of the XML page, it looks like Wordpress is generating these: <generator>http://wordpress.org/?v=3.5.2</generator> Any idea how to get them out of Google's index without 301 redirecting them? We need the Wordpress-generated RSS feeds to work for various uses. My first two thoughts are trying to work with our Development team to see if we can get a "noindex" meta robots tag on the pages, by they are dynamically-generated pages...so I'm not sure if that will be possible. Or, perhaps we can add a "feed" paramater to GWT "URL Parameters" section...but I don't want to limit Google from crawling these again...I figure I need Google to crawl them and see some code that says to get the pages out of their index...and THEN not crawl the pages anymore. I don't think the "Remove URL" feature in GWT will work, since that tool only removes URLs from the search results, not the actual Google index. FWIW, this site is using the Yoast plugin. We set every page type to "noindex" except for the homepage, Posts, Pages and Categories. We have other sites on Yoast that do not have any /feed URLs indexed by Google at all. Side note, the /robots.txt file was previously blocking crawling of the /feed URLs on this site, which is why you'll see that note in the Google SERPs when you click on the query link given in the first paragraph.

What if I point my canonicals to a URL version that is not used in internal links
My web developer has pointed the "good" URLs that I use in my internal link structure (top-nav/footer) to another duplicate version of my pages. Now the URLs that receive all the canonical link value are not the ones I use on my website. is this a problem and why??? In theory the implementation is good because both have equal content. But does it harm my link equity if it directs to a URL which is not included in my internal link architecture.

'No Follow' and 'Do Follow' links when using WordPress plugins
Hi all I hope someone can help me out with the following question in regards to 'no follow' and 'do follow' links in combination with WordPress plugins. Some plugins that deal with links i.e. link masking or SEO plugins do give you the option to 'not follow' links. Can someone speak from experience that this does actually work?? It's really quite stupid, but only occurred to me that when using the FireFox add on 'NoDoFollow' as well as looking at the SEOmoz link profile of course, 95% of my links are actually marked as FOLLOW, while the opposite should be the case. For example I mark about 90% of outgoing links as no follow within a link masking plugin. Well, why would WordPress plugins give you the option to mark links as no follow in the first place when they do in fact appear as follow for search engines and SEOmoz? Is this a WordPress thing or whatnot? Maybe they are in fact no follow, and the information supplied by SEO tools comes from the basic HTML structure analysis. I don't know... This really got me worried. Hope someone can shed a light. All the best and many thanks for your answers!

Canonical on ecommerce pages
I have seen some competitors using the nofollow tag as well as canonical on all refinements and sorts on their ecommerce pages. Example being if you went to their hard drive category page and refined by 500gb hard drives then that page would have a canonical element to send it back to hard drives page without the refinement. I see how this could be good for control indexation and the amount pages Google crawls, but do you see problems in using the canonical tag this way? Also I have seen competitors have category page descriptions (describing what that type of product is) on all pagenation and refinements (the exact same block of text on all of the pages). Would this be a duplicate content problem or is it not that big of a deal since the content is only on their site so they are only competiting with themselves. Thanks for your help

Rel=Canonical to Rewrite or original URL?
Working with a large number of duplicate pages due to different views of products. Rewriting URLs for the most linked page. Should rel=canonical point to the rewritten URL or the actual URL? Is there a way to see what the rewritten URL is within the crawl data? I was taking the approach of rewriting only the base version of each page and then using a rel=canonical on the duplicate pages. Can anyone recommend a better or cleaner approach? Haven't seen too many articles on retail SEO when faced with a less than optimized CMS. Thanks!
