Duplicate Content Errors new website. How do you know which page to put the rel canonical tag on?
-
I am having problems with duplicate content. This is a new website and all the pages have the same page and domain rank, the following is an example of the homepage. How do you know which page to use the canonical tag on?
http://medresourcesupply.com/index.php
Would this be the correct way to use this?
Here is another example where Moz says these are duplicates. I can't figure out why because they have different url's and content.

Thanks for the response Ruth, that was very helpful.

It looks like for that second link, there is no text content on the page - only one big image with the specifications of the item. That brings the unique text content on the page down to almost 0. The picture of the man clutching his throat is also just a page with one image on it, and no text. Since neither the Moz Crawl Test tool nor Googlebot can see pictures, they are left with the impression that these pages are almost identical.
It's important to remember that the canonical tag is only one way to address duplicate content concerns - "duplicate content" doesn't always mean "canonical tag." Sometimes, when pages have very little content, they appear to be identical or near-identical even if their intents are different. In that case, I recommend seeing what you could do to make the pages more unique. With image pages, I wouldn't worry too much about adding content, but for pages like http://medresourcesupply.com/index.php?src=gendocs&ref=detailed_specfications &category=Main, where there is content, but it's contained within an image, I would recommend recreating the text contained in that image, but in HTML text. You could also expand upon the specs to make them more detailed, which will add to the unique content of the page and help users figure out if this is the item they really want.

Thanks for the response. So I would want to put the canonical tag on all other versions of the homepage except the /index.php one?
"for e.g., this page
http://medresourcesupply.com/index.php?src=gendocs&ref=detailed_specfications &category=Main
should have this rel canonical tag
"
The first link is a different page from the homepage. Why would I want to place the canonical tag for the hompage on this one?

[E-commerce] Duplicate content due to color variations (canonical/indexing)
Hello, We currently have a lot of color variations on multiple products with almost the same content. Even with our canonicals being set, Moz's crawling tool seems to flag them as duplicate content. What we have done so far: Choosing the best-selling color variation (our "master product") Adding a rel="canonical" to every variation (with our "master product" as the canonical URL) In my opinion, it should be enough to address this issue. However, being given the fact that it's flagged as duplicate by Moz, I was wondering if there is something else we should do? Should we add a "noindex,follow" to our child products and "index,follow" to our master product? (sounds to me like such a heavy change) Thank you in advance

Need help with huge spike in duplicate content and page title errors.
Hi Mozzers, I come asking for help. I've had a client who's reported a staggering increase in errors of over 18,000! The errors include duplicate content and page titles. I think I've found the culprit and it's the News & Events calender on the following page: http://www.newmanshs.wa.edu.au/news-events/events/07-2013 Essentially each day of the week is an individual link, and events stretching over a few days get reported as duplicate content. Do you have any ideas how to fix this issue? Any help is much appreciated. Cheers

Rel canonical on every page, pointing to home page
I've just started working with a client and have been surprised to find that every page of their site (using Concrete5 CMS) has a rel=canonical pointing to their home page. I'm feeling really dumb, because this seems like a fatal flaw which would keep Google from ranking any page other than the home page... but when I look at Google Analytics, Content > Site Content > Landing Pages, using Secondary Dimension = Source, it seems that Google is delivering users to numerous pages on their site. Can anyone help me out?! Thanks very much!!

Duplicate content from development website
Hi all - I've been trawling for duplicate content and then I stumbled across a development URL, set up by a previous web developer, which nearly mirrors current site (few content and structure changes since then, but otherwise it's all virtually the same). The developer didn't take it down when the site was launched. I'm guessing the best thing to do is tell him to take down the development URL (which is specific to the pizza joint btw, immediately. Is there anything else I should ask him to do? Thanks, Luke

Duplicate page content and Duplicate page title errors
Hi, I'm new to SeoMoz and to this forum. I've started a new campaign on my site and got back loads of error. Most of them are Duplicate page content and Duplicate page title errors. I know I have some duplicate titles but I don't have any duplicate content. I'm not a web developer and not so expert but I have the impression that the crawler is following all my internal links (Infact I have also plenty of warnings saying "Too many on-page links". Do you think this is the cause of my errors? Should I implement the nofollow on all internal links? I'm working with Joomla. Thanks a lot for your help Marco

Mobile Site - Same Content, Same subdomain, Different URL - Duplicate Content?
I'm trying to determine the best way to handle my mobile commerce site. I have a desktop version and a mobile version using a 3rd party product called CS-Cart. Let's say I have a product page. The URLs are... mobile:
Intermediate & Advanced SEO | | grayloon
store.domain.com/index.php?dispatch=categories.catalog#products.view&product_id=857 desktop:
store.domain.com/two-toned-tee.html I've been trying to get information regarding how to handle mobile sites with different URLs in regards to duplicate content. However, most of these results have the assumption that the different URL means m.domain.com rather than the same subdomain with a different address. I am leaning towards using a canonical URL, if possible, on the mobile store pages. I see quite a few suggesting to not do this, but again, I believe it's because they assume we are just talking about m.domain.com vs www.domain.com. Any additional thoughts on this would be great!0 -
Fixing Duplicate Content Errors
SEOMOZ Pro is showing some duplicate content errors and wondered the best way to fix them other than re-writing the content. Should I just remove the pages found or should I set up permanent re-directs through to the home page in case there is any link value or visitors on these duplicate pages? Thanks.
