Cross Domain Duplicate Content
-
Hi
My client has a series of websies, one main website and several mini websites, articles are created and published daily and weekly, one will go on a the main website and the others on one, two, or three of the mini sites.
To combat duplication, i only ever allow one article to be indexed (apply noindex to articles that i don't wanted indexed by google, so, if 3 sites have same article, 2 sites will have noindex tag added to head).
I am not completely sure if this is ok, and whether there are any negative affects, apart from the articles tagged as noindex not being indexed. Are there any obvious issues?
I am aware of the canonical link rel tag, and know that this can be used on the same domain, but can it be used cross domain, in place of the noindex tag?
If so, is it exactly the same in structure as the 'same domain' canonical link rel tag?
Thanks
Matt

Thanks Adam
Is there a problem with using noindex as noted in my original post?
Having read a bit about canonical now and watched matt cutts video, the advice is to use other forms of redirect, e.g. 301, first, 'rel=”canonical” link element is seen as a hint and not an absolute directive' However, is not feasible that client can manually upload an ediited .htacess file with new 301 redirect each time and article is uploaed, acorss different domains.
So, what i am trying to say is, what would be the best method in my situation?

Yes, the canonical tag will work across domains: http://searchengineland.com/google-supports-cross-domain-canonical-tag-32044

Duplicate content in Shopify reported by Moz
According to Moz crawl report, there are hundreds of duplicate pages in our Shopify store ewatchsale.com. The main duplicate pages are:
On-Page Optimization | | ycnetpro101
https://ewatchsale.com/collections/seiko-watches?page=2
https://ewatchsale.com/collections/all/brand_seiko
(the canonical page should be https://ewatchsale.com/collections/seiko-watches) https://ewatchsale.com/collections/seiko-watches/gender_mens
(the canonical page should be https://ewatchsale.com/collections/seiko-watches/mens-watches) Also, I want to exclude indexing of pages URLs with "filter parameters" like https://ewatchsale.com/collections/seiko-watches/color_black+mens-watches+price_us-100-200 Shopify advised we can't access our robots.txt file. How can we exclude SE crawling of the page URLs with filter names?
How can we access the robots.txt file?
How can we add canonical code to the preferred collection pages? Which templates and what codes to add? Thanks for your advice in advance!0 -
Potential duplicate content issue?
We have a category on our website for PVC rolls to buy as standard 50m rolls (this includes 15 products in the category). We're also releasing PVC rolls to buy per metre (10m roll/25m roll etc...), again with 15 products, which we are adding as a separate category as it makes more sense for our customers and removes the risk of having too many options. Would using the same description be bad practice for SEO? The product is exactly the same just available in different roll sizes, but we definitely do not want to combine categories as it doesn't work for our customers. Any help or suggestions would be appreciated, thanks.

Effecting Domain Authority
I've taking an old brochure website and done 61 Pages and 10 Post pages On-page SEO and my Domain Authority is still a '1.' I've used Low Difficulty Keywords and gotten Grade A in On-page Moz reports. We've even keyworded 400 images - Alt text. My competitors have done nothing and they have domain authority at least in the 40s...... Am I doing anything wrong?

Duplicate Content aka 301 redirect from .com to .com/index.html
Moz reports are telling me that I have duplicate content on the home page because .com and .com/index.html are being seen as two pages. I have implemented 301 redirect using various codes I found online, but nothing seems to work. Currently I'm using this code. RewriteEngine On
On-Page Optimization | | omakad
RewriteBase /
RewriteCond %{HTTP_HOST} ^jacksonvilleacservice.com
RewriteRule ^index.html$ http://www.jacksonvilleacservice.com/ [L,R=301] Nothing is changing. What am I doing wrong? I have given it several weeks but report stays the same. Also according to webmasters tools they can't see this as duplicate content. What am I doing wrong?0 -
Does this site have a duplicate content issue?
Google WMT is showing me only 2 short meta descriptions under "HTML Improvements" but I believe http://www.customgia.com may have a content duplication issue. Numerous keywords are used repeatedly across many product descriptions. To make matters worse, every product page has a "Design It!" button that sends the user to a flash-based jewelry designer in which they can edit the product's appearance. I'm not sure if these "designer pages" are adding unnecessary and potentially damaging duplicate content but it's certainly a possibility. There are many items on this site that are similar to one another but not the same. The product description tend to use the same phrases over and over again - words like crystal, Swarovski, beaded, design it, customize, change, pearl, glass beads, iridescent, pearl, drop earrings are used a lot. What I'm stuck on is whether or not I should be focusing on a content duplication issue as the primary SEO problem or if there is something bigger. Thank you for any assistance you can provide!

Is duplicate content harmful? Example from on my site
I'm not talking about content copied from another site but content unique to a site being used on several pages. I have a delivery tab that has precisely the same content as another product page. This content is on four product pages and the dedicated delivery page. Thanks
