Does turning website content into PDFs for document sharing sites cause duplicate content?
-
Website content is 9 tutorials published to unique urls with a contents page linking to each lesson. If I make a PDF version for distribution of document sharing websites, will it create a duplicate content issue? The objective is to get a half decent link, traffic to supplementary opt-in downloads.
-
.pdf documents are indexed and will compete in the search results along with web pages. They accumulate pagerank and any links on them are followed and credited the same as a web page.
So, if you have copies of your webpages in pdf format then you should expect them to attract at least some of the traffic that would have gone to your webpage. It is possible for them to rank higher than your webpages - especially if you optimize them by giving them document titles.
I believe that they can lead to duplicate content problems. I have lots of pdfs on my sites. To prevent duplicate content problems I have used htaccess to rel=canonical them to the corresponding webpage.

As far as I know, it can't. But "if" you turned that PDF into a webpage, then yes. I don't think it's something to even worry about.

Purchasing duplicate content
Morning all, I have a client who is planning to expand their product range (online dictionary sites) to new markets and are considering the acquisition of data sets from low ranked competitors to supplement their own original data. They are quite large content sets and would mean a very high percentage of the site (hosted on a new sub domain) would be made up of duplicate content. Just to clarify, the competitor's content would stay online as well. I need to lay out the pros and cons of taking this approach so that they can move forward knowing the full facts. As I see it, this approach would mean forgoing ranking for most of the site and would need a heavy dose of original content as well as supplementing the data on page to build around the data. My main concern would be that launching with this level of duplicate data would end up damaging the authority of the site and subsequently the overall domain. I'd love to hear your thoughts!

Avoiding duplicate content on internal pages
Lets say I'm working on a decorators website and they offer a list of residential and commercial services, some of which fall into both categories. For example "Internal Decorating" would have a page under both Residential and Commercial, and probably even a 3rd general category of Services too. The content inside the multiple instances of a given page (i.e. Internal Decorating) at best is going to be very similar if not identical in some instances. I'm just a bit concerned that having 3 "Internal Decorating" pages could be detrimental to the website's overall SEO?

Techniques for diagnosing duplicate content
Buonjourno from Wetherby UK 🙂 Diagnosing duplicate content is a classic SEO skill but I'm curious to know what techniques other people use. Personally i use webmaster tools as illustrated here: http://i216.photobucket.com/albums/cc53/zymurgy_bucket/webmaster-tools-duplicate.jpg but what other techniques are effective? Thanks,

Duplicate Content on SEO Pages
I'm trying to create a bunch of content pages, and I want to know if the shortcut I took is going to penalize me for duplicate content. Some background: we are an airport ground transportation search engine(www.mozio.com), and we constructed several airport transportation pages with the providers in a particular area listed. However, the problem is, sometimes in a certain region multiple of the same providers serve the same places. For instance, NYAS serves both JFK and LGA, and obviously SuperShuttle serves ~200 airports. So this means for every airport's page, they have the super shuttle box. All the provider info is stored in a database with tags for the airports they serve, and then we dynamically create the page. A good example follows: http://www.mozio.com/lga_airport_transportation/ http://www.mozio.com/jfk_airport_transportation/ http://www.mozio.com/ewr_airport_transportation/ All 3 of those pages have a lot in common. Now, I'm not sure, but they started out working decently, but as I added more and more pages the efficacy of them went down on the whole. Is what I've done qualify as "duplicate content", and would I be better off getting rid of some of the pages or somehow consolidating the info into a master page? Thanks!

Duplicate content
I'm getting an error showing that two separate pages have duplicate content. The pages are: | Help System: Domain Registration Agreement - Registrar Register4Less, Inc. http://register4less.com/faq/cache/11.html 1 27 1 Help System: Domain Registration Agreement - Register4Less Reseller (Tucows) http://register4less.com/faq/cache/7.html | These are both registration agreements, one for us (Register4Less, Inc.) as the registrar, and one for Tucows as the registrar. The pages are largely the same, but are in fact different. Is there a way to flag these pages as not being duplicate content? Thanks, Doug.

Does 'framing' a website create duplicate content?
Something I have not come across before, but hope others here are able offer advice based on experience: A client has independently created a series of mini-sites, aimed at targeting specific locations. The tactic has worked very well and they have achieved a large amount of well targeted traffic as a result. Each mini-site is different but then in the nav, if you want to view prices or go to the booking page, that then links to what at first appears to be their main site. However, you then notice that the URL is actually situated on the mini-site. What they have done is 'framed' the main site so that it appears exactly the same even when navigating through this exact replica site. Checking the code, there is almost nothing there - in fact there is actually no content at all. Below the head, there is a piece of code: <frameset rows="*" framespacing=0 frameborder=0> <frame src="[http://www.example.com](view-source:http://www.yellowskips.com/)" frameborder=0 marginwidth=0 marginheight=0> <noframes>Your browser does not support frames. Click [here](http://www.example.com) to view.noframes> frameset> Given that main site content does not appear to show in the source code, do we have an issue with duplicate content? This issue is that these 'referrals' are showing in Analytics, despite the fact that the code does not appear in the source, which is slightly confusing for me. They have done this without consultation and I'm very concerned that this could potentially be creating duplicate content of their ENTIRE main site on dozens of mini-sites. I should also add that there are no links to the mini-sites from the main site, so if you guys advise that this is creating duplicate content, I would not be worried about creating a link-wheel if I advise them to link directly to the main site rather than the framed pages. Thanks!
