Getting rid of duplicate content with rel=canonical
-
This may sound like a stupid question, however it's important that I get this 100% straight.
A new client has nearly 6k duplicate page titles / descriptions. To cut a long story short, this is mostly the same page (or rather a set of pages), however every time Google visits these pages they get a different URL. Hence the astronomical number of duplicate page titles and descriptions.
Now the easiest way to fix this looks like canonical linking. However, I want to be absolutely 100% sure that Google will then recognise that there is no duplicate content on the site. Ideally I'd like to 301 but the developers say this isn't possible, so I'm really hoping the canonical will do the job.
Thanks.

Thank you both, much appreciated. Their rankings have suffered in the last two weeks and this coincides with their developers creating all this duplicate content - let's see if this fixes that issue!
Thanks again.

Hi mj1984,
The canonical tag is your only option here. The problem with duplicate content is really about control:
(i) Controlling Link Juice (past + future)
(ii) Controlling the targeted landing page within your campaign
Google will devalue certain identical pages, but they will always favour one. They do not, as far as I am aware, devalue all content that is duplicated (including the original) - So your concern isn't that your site is being devalued, simpliciter (often an immediate unwarranted concern). It is that Google will select one duplicate page and favour that above the others.
The canonical tag exists for you to control this.
So, will Google recognise there is no duplicate content?. It should, it might not, but I wouldn't worry about this. For the canonical tags that it does pick up (& eventually) - you can be confident that the page you want to rank, will be the one ranking.

To me this sounds like a clear-cut case of a need for the canonical tag.

HI There, Hoping someone can help me - before i damage my desk banging my head. Getting notifications from ahrefs and Moz for duplicate content. I have no idea where these weird urls have came from , but they do take us to the correct page (but it seems a duplicate of this page). correct url http://www.acsilver.co.uk/shop/pc/Antique-Vintage-Rings-c152.htm Incorrect url http://www.acsilver.co.uk/shop/pc/vintage-Vintage-Rings- c152.htm This is showing for most of our store categories 😞 Desperate for help as to what could be causing these issues. I have a technical member of the ecommerce software go through the large sitemap files and they assured me it wasn't linked to the sitemap files. Gemma

Handling of Duplicate Content
I just recently signed and joined the moz.com system. During the initial report for our web site it shows we have lots of duplicate content. The web site is real estate based and we are loading IDX listings from other brokerages into our site. If though these listings look alike, they are not. Each has their own photos, description and addresses. So why are they appear as duplicates – I would assume that they are all too closely related. Lots for Sale primarily – and it looks like lazy agents have 4 or 5 lots and input the description the same. Unfortunately for us, part of the IDX agreement is that you cannot pick and choose which listings to load and you cannot change the content. You are either all in or you cannot use the system. How should one manage duplicate content like this? Or should we ignore it? Out of 1500+ listings on our web site it shows 40 of them are duplicates.

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

Need help with rel canonical!
I have a client who's MOZ crawl is coming back with 62 "notices" about rel canonical. Is this bad? On the report, it lists the url, then "Tag Value" as the home page.....what does this mean exactly? Are they pointing all the pages to the home page? I think I have 301 and rel can confused....

Avoiding Cannibalism and Duplication with content
Hi, For the example I will use a computers e-commerce store... I'm working on creating guides for the store -
Technical SEO | | BeytzNet
How to choose a laptop
How to choose a desktop I believe that each guide will be great on its own and that it answers a specific question (meaning that someone looking for a laptop will search specifically laptop info and the same goes for desktop). This is why I didn't creating a "How to choose a computer" guide. I also want each guide to have all information and not to start sending the user to secondary pages in order to fill in missing info. However, even though there are several details that are different between the laptops and desktops, like importance of weight, screen size etc., a lot of things the checklist (like deciding on how much memory is needed, graphic card, core etc.) are the same. Please advise on how to pursue it. Should I just write two guides and make sure that the same duplicated content ideas are simply written in a different way?0 -
Duplicate content in Magento
Hi all We got some serious issues with duplicate content on a Magento site that we are marketing. For example: http://www.citcop.se/varmepumpar-luft-luft/panasonic/panasonic-nordic-ce9nke-5-0kw http://www.citcop.se/panasonic/panasonic-nordic-ce9nke-5-0kw http://www.citcop.se/panasonic-nordic-ce9nke-5-0kw All of the above seem to work just fine as it is now but since they are excatly the same product they should ofcourse do a 301 redirect to the main page. Any ideas on how to sort this out in Magnto without having to resort to manual work in .htaccess? Have a great day Fredrik

Duplicate content handling.
Hi all, I have a site that has a great deal of duplicate content because my clients list the same content on a few of my competitors sites. You can see an example of the page here: http://tinyurl.com/62wghs5 As you can see the search results are on the right. A majority of these results will also appear on my competitors sites. My homepage does not seem to want to pass link juice to these pages. Is it because of the high level of Dup Content or is it because of the large amount of links on the page? Would it be better to hide the content from the results in a nofollowed iframe to reduce duplicate contents visibilty while at the same time increasing unique content with articles, guides etc? or can the two exist together on a page and still allow link juice to be passed to the site. My PR is 3 but I can't seem to get any of my internal pages(except a couple of pages that appear in my navigation menu) to budge of the PR0 mark even if they are only one click from the homepage.
