Do mobile and desktop sites that pull content from the same source count as duplicate content?
-
We are about to launch a mobile site that pulls content from the same CMS, including metadata. They both have different top-level domains, however (www.abcd.com and www.m.abcd.com). How will this affect us in terms of search engine ranking?
-
Correct.
-
Thanks Michael. To be clear, this means that the desktop will only have rel= alternate(pointing to mobile) and the mobile will only have rel=canonical(pointing to desktop)?
-
Be sure you follow the best practices outlined here for separate mobile sites. In short, you want the desktop pages to have a rel alternate tag pointing at the mobile equivalent, and the mobile pages having their rel canonical pointing at the desktop equivalents.
-
If you are using a CMS, Content Management System, think of it as a database. When someone hits your website the CMS looks into its files and serves up the information to the browser, which is different than the older static websites. A true CMS will be able to determine what browser/device the individual is viewing from and then serve up the appropriate information.
If you have two separate domains however you may need to tell Google what's going on, i.e rel=”canonical”. Not doing so may run trigger some duplicate content issues. However, having two different websites is perfectly acceptable by Google, just make sure you have the proper rel=”canonical” tags and you should be ok.
This one one of the benefits to Responsive templates within a CMS. It allows you to have one set of content, that alters depending on the browsing device.

Does the www version redirect to the m. version based on device?
In my opinion, it will not have too much of an effect because you are telling the bots that the m. version is the mobile version of your site and it is expected to have the same content as the desktop version.

Does duplicate content not concern Rand?
Hello all, I'm a new SEOer and I'm currently trying to navigate the layman's minefield that is trying to understand duplicate content issues in as best I can. I'm working on a website at the moment where there's a duplicate content issue with blog archives/categories/tags etc. I was planning to beat this by implementing a noindex meta tag on those pages where there are duplicate content issues. Before I go ahead with this I thought: "Hey, these Moz guys seem to know what they're doing! What would Rand do?" Blogs on the website in question appear in full and in date order relating to the tag/category/what-have-you creating the duplicate content problem. Much like Rand's blog here at Moz - I thought I'd have a look at the source code to see how it was dealt with. My amateur eyes could find nothing to help answer this question: E.g. Both the following URLs appear in SERPs (using site:moz,com and very targeted keywords, but they're there): https://moz.com/rand/does-making-a-website-mobile-friendly-have-a-universally-positive-impact-on-mobile-traffic/ https://moz.com/rand/category/moz/ Both pages have a rel="canonical" pointing to themselves. I can understand why he wouldn't be fussed about the category not ranking, but the blog? Is this not having a negative effect? I'm just a little confused as there are so many conflicting "best practice" tips out there - and now after digging around in the source code on Rand's blog I'm more confused than ever! Any help much appreciated, Thanks

Value in Consolidating Similar Sites / Duplicate Content for Different URLs
We have 5 ecommerce sites: one company site with all products, and then four product-specific sites with relevant URL titles and products divided up between them (www.companysite.com, www.product1.com, www.product2.com, etc). We're thinking of consolidating the smaller sites into our most successful site (www.product1.com) in order to save management time and money, even though I hate to lose the product-specific URLs in search results. Is this a wise move? If we proceed, all of the products will be available on both our company site and our most successful site (www.company.com & www.product1.com). This would unfortunately give us two sites of duplicate content, since the products will have the same pictures, descriptions, etc. The only difference would be the URL. Would we face penalties from Google, even though it would make sense to continue to carry our products on our company site?

Partially duplicated content on separate pages
TL;DR: I am writing copy for some web pages. I am duplicating some bits of copy exactly on separate web pages. And in other cases I am using the same bits of copy with slight alterations. Is this bad for SEO? Details: We sell about 10 different courses. Each has a separate page. I'm currently writing copy for those pages. Some of the details identical for each course. So I can duplicate the content and it will be 100% applicable. For example, when we talk about where we can run courses (we go to a company and run it on their premises) – that's applicable to every course. Other bits are applicable with minor alterations. So where we talk about how we'll tailor the course, I will say for example: "We will the tailor the course to the {technical documents|customer letters|reports} your company writes." Or where we have testimonials, the headline reads "Improving {customer writing|reports|technical documents} in every sector and industry". There is original content on each page. The duplicate stuff may seem spammy, but the alternative is me finding alternative re-wordings for exactly the same information. This is tedious and time-consuming and bizarre given that the user won't notice any difference. Do I need to go ahead and re-write these bits ten slightly different ways anyway?

Https Duplicate Content
My previous host was using shared SSL, and my site was also working with https which I didn’t notice previously. Now I am moved to a new server, where I don’t have any SSL and my websites are not working with https version. Problem is that I have found Google have indexed one of my blog http://www.codefear.com with https version too. My blog traffic is continuously dropping I think due to these duplicate content. Now there are two results one with http version and another with https version. I searched over the internet and found 3 possible solutions. 1 No-Index https version

Duplicate content issue with trailing / ?
Hi ,I did a SEOmoz Crawl Test and found most pages show twice, for example: A: www.website.com/index.php/dog/walk B: www.website.com/index.php/dog/walk/ I've checked Google Analytics and 90% of organic search traffic arrives on the URLs with the trailing slash (B). Question 1: Can I assume I've a duplicate content problem? Question 2: Is it best to do 301 redirects from the 'non trailing slash' pages to the 'trailing slash pages'? Question 3: For some reason every web page has a '/index.php' in it (see A&B) above. No idea why. Should it be a SEO concern? Kind regards and thank you in advance Nigel

Duplicate Content Issues - Should I build a new site?
I'm currently working on a site which is built using Zen Cart. The client also has another version which has the same products on it. The product descriptions and the vast majority of the text has been re-written. I've used the duplicate content tool and these are the results: HTML fingerprint: 0000a7ee1f07a131 0000a7ec1f07a931 92.31% Total HTML similarity: 76.33% Standard text similarity: 66.72% Smart text similarity: 45.81% Total text similarity 56.27% I considered using a different eCommerce system like Magento or Volusion. So I had a look at a few templates, chose one and then used the tool again and got the following: HTML fingerprint: 0000a7e41b012111 0000a7ec1f07a931 72.00% Total HTML similarity: 64.65% Standard text similarity: 11.69% Smart text similarity: 17.90% Total text similarity 14.80% Do you think its worth doing this? thanks Dan
