Canonical Vs No Follow for Duplicate Products
-
I am in the process of migrating a site from Volusion to BigCommerce. There is a limitation on the ability to display one product in 2 different ways.
Here is the situation. One of the manufacturers will not allow us to display products to customers who are not logged in. We have convinced them to let us display the products with no prices. Then we created an Exclusive Contractor section that will allow users to see the price and be able to purchase the products online. Originally we were going to just direct users to call to make purchases like our competitors are doing. Because we have a large amount of purchasers online we wanted to manipulate the system to be able to allow online purchases.
Since these products will have duplicates with no pricing I was thinking that Canonical tags would be kind of best practice. However, everything will be behind a firewall with a message directing people to log in. Since this will undoubtedly create a high bounce rate I feel like I need to no follow those links. This is a rather large site, over 5000 pages. The 250 no follow URLs most likely won't have a large impact on the overall performance of the site. Or so I hope anyway. My gut tells me if these products are going to technically be hidden from the searcher they should also be hidden from the engines.
Does Disallowing these URLs seem like a better way to do this than simply using the Canonical tags? Any thoughts or suggestions would be really helpful!

They are different things for used for different reasons. By using the robots to block any page behind a log in you will not have to worry about them trying to access that information at all. You should also have canonical tags pointing to themselves on all pages especially product pages and landing pages.

I didn't think the engines could see the information. So if I understand you correctly you are saying that blocking the URLs in the .txt file is better than using a canonical tag right?

If your duplicate pages are behind a log-in you will be fine as content behind it cannot be seen by search engines. You should also block your logged in pages using your robots.txt.

Duplicating content from manufacturer for client site and using canonical reference.
We manage content for many clients in the same industry, and many of them wish to keep their customers on their individualized websites (understandably). In order to do this, we have duplicated content in part from the manufacturers' pages for several "models" on the client's sites. We have put in a Canonical reference at the start of the content directing back to the manufacturer's page where we duplicated some of the content. We have only done a handful of pages while we figure out the canonical reference potential issue. So, my questions are: Is this necessary? Does this hurt, help or not do anything SEO-wise for our ranking of the site? Thanks!

How would you handle this duplicate content - noindex or canonical?
Hello Just trying look at how best to deal with this duplicated content. On our Canada holidays page we have a number of holidays listed (PAGE A)
Intermediate & Advanced SEO | | KateWaite
http://www.naturalworldsafaris.com/destinations/north-america/canada/suggested-holidays.aspx We also have a more specific Arctic Canada holidays page with different listings (PAGE B)
http://www.naturalworldsafaris.com/destinations/arctic-and-antarctica/arctic-canada/suggested-holidays.aspx Of the two, the Arctic Canada page (PAGE B) receives a far higher number of visitors from organic search. From a user perspective, people expect to see all holidays in Canada (PAGE A), including the Arctic based ones. We can tag these to appear on both, however it will mean that the PAGE B content will be duplicated on PAGE A. Would it be the best idea to set up a canonical link tag to stop this duplicate content causing an issue. Alternatively would it be best to no index PAGE A? Interested to see others thoughts. I've used this (Jan 2011 so quite old) article for reference in case anyone else enters this topic in search of information on a similar thing: Duplicate Content: Block, Redirect or Canonical - SEO Tips0 -
Canonical Help (this is a nightmare)
Hi, We're new to SEO and trying to fix our domain canonical issue. A while back we were misusing the "link canonical" tag such that Google was tracking params (e.g. session ids, tagging ) all as different unique urls. This created a nightmare as now Google thinks there's millions of pages associated with our domain when the reality is really a couple thousand unique links. Since then, we've tried to fix this by: 1) specifying params to ignore via SEO webmasters 2) properly using the canonical tag. However, I'm still recognizing there's a bunch of outsanding search results that resulted from this mess. Any idea on expectation on when we'd see this cleaned up? I'm also recognizing that google is looking at http://domain.com and https://domain.com as 2 different pages even though we specify to only look at "http://domain.com" via the link canonical tag. Again, is this just a matter of waiting for Google to update its results? We submitted a site map but it seems like it's taking forever for the results of our site to clear up... Any help or insight would greatly be appreciated!

Duplicate content within sections of a page but not full page duplicate content
Hi, I am working on a website redesign and the client offers several services and within those services some elements of the services crossover with one another. For example, they offer a service called Modelling and when you click onto that page several elements that build up that service are featured, so in this case 'mentoring'. Now mentoring is common to other services therefore will feature on other service pages. The page will feature a mixture of unique content to that service and small sections of duplicate content and I'm not sure how to treat this. One thing we have come up with is take the user through to a unique page to host all the content however some features do not warrant a page being created for this. Another idea is to have the feature pop up with inline content. Any thoughts/experience on this would be much appreciated.

Canonical Tags?
I read that Google will "honor" these tags if your website has two url's with duplicate content. The duplicate content does not show up in my SEOmoz crawls report but they do in the search engines and many of "non authoritative links" that are generated from my search feature j(ugly url's with % ...not real user friendly) are ranking higher than the "good URL" links. So if I do the canonical tags I guess my higher ranking bad urls will drop. I even read that google might even completely overlook the links. I read somewhere that the best way to do this is with a 301 redirect...is that correct? I m ranking pretty good with my main keyword terms so I am afraid to make changes not knowing the effect. Any suggestions? Thanks, Boo
