PDF on financial site that duplicates ~50% of site content
-
I have a financial advisor client who has a downloadable PDF on his site that contains about 9 pages of good info. Problem is much of the content can also be found on individual pages of his site.
Is it best to noindex/follow the pdf? It would be great to let the few pages of original content be crawlable, but I'm concerned about the duplicate content aspect.
Thanks --

This is what we have done with pdfs. Assign rel="canonical" in .htaccess.
We did this with a few hundred files and it took google a LONG time to find and credit them.

You could set the header to noindex rather than rel=canonical
-
Personally I think it would be better not to index, it but if necessary, the index folder root seems like a good option
-
Thanks. Anybody want to weigh in on where to rel=canonical to? Home page?

If you are using apache, you should put it on your .htaccess with this form
<filesmatch “my-file.pdf”="">Header set Link ‘<http: misite="" my-file.html="">; rel=”canonical”‘</http:></filesmatch>
-
I think the right way here is to put the rel canonical in PDF header http://googlewebmastercentral.blogspot.com/2011/06/supporting-relcanonical-http-headers.html

I thought the idea was to put rel=canonical on the duplicated page, to signal that "hey, this page may look like duplicate content, but please refer to this canonical URL"?
Looks like there is a pdf option for rel=canonical, I guess the question is, what page on the site to make canonical?
http://support.google.com/webmasters/bin/answer.py?hl=en&answer=139394
Indicate the canonical version of a URL by responding with the
Link rel="canonical"HTTP header. Addingrel="canonical"to theheadsection of a page is useful for HTML content, but it can't be used for PDFs and other file types indexed by Google Web Search. In these cases you can indicate a canonical URL by responding with theLink rel="canonical"HTTP header, like this (note that to use this option, you'll need to be able to configure your server):Link: <http: www.example.com="" downloads="" white-paper.pdf="">; rel="canonical"</http:>

Hi Keith,
I'm sorry, I should have clarified. The rel=canonical tags would be on your Web pages, not the PDF (they are irrelevant in a PDF document). Then Google will attribute your Web page as the original source of the content and will understand that the PDF just contains bits of content from those pages. In this instance I would include a rel=canonical tag on every page of your site, just to cover your bases. Hope that helps!

Not sure which page I would mark as being canonical, since the pdf contains content from several different pages on the site. I don't think it's possible to assign different rel=canonical tags to separate portions of a pdf, is it?
-
As long as you have rel=canonical tags properly in place, you don't need to worry about the PDF causing duplicate content problems. That way, any original content should be picked up and any duplicate can be attributed to your existing Web pages. Hope that's helpful!

Backup Server causing duplicate content flag?
Hi, Google is indexing pages from our backup server. Is this a duplicate content issue? There are essentially two versions of our entire domain indexed by Google. How do people typically handle this? Any thoughts are appreciated. Thanks, Yael

Duplicate Content through 'Gclid'
Hello, We've had the known problem of duplicate content through the gclid parameter caused by Google Adwords. As per Google's recommendation - we added the canonical tag to every page on our site so when the bot came to each page they would go 'Ah-ha, this is the original page'. We also added the paramter to the URL parameters in Google Wemaster Tools. However, now it seems as though a canonical is automatically been given to these newly created gclid pages; below https://www.google.com.au/search?espv=2&q=site%3Awww.mypetwarehouse.com.au+inurl%3Agclid&oq=site%3A&gs_l=serp.3.0.35i39l2j0i67l4j0i10j0i67j0j0i131.58677.61871.0.63823.11.8.3.0.0.0.208.930.0j3j2.5.0....0...1c.1.64.serp..8.3.419.nUJod6dYZmI Therefore these new pages are now being indexed, causing duplicate content. Does anyone have any idea about what to do in this situation? Thanks, Stephen.

Duplicate content when changing a site's URL due to algorithm penalty
Greetings A client was hit by penguin 2.1, my guess is that this was due to linkbuilding using directories. Google webmaster tools has detected about 117 links to the site and they are all from directories. Furthermore, the anchor texts are a bit too "perfect" to be natural, so I guess this two factors have earned the client's site an algorithm penalty (no manual penalty warning has been received in GWT). I have started to clean some of the backlinks, on Oct the 11th. Some of the webmasters I asked complied with my request to eliminate backlinks, some didn´t, I disavowed the links from the later. I saw some improvements on mid october for the most important KW (see graph) but ever since then the rankings have been falling steadily. I'm thinking about giving up on the domain name and just migrating the site to a new URL. So FINALLY MY QUESTION IS: if I migrate this 6-page site to a new URL, should I change the content completely ? I mean, if I just copy paste the content of the curent site into a new URL I will incur in dpolicate content, correct?. Is there some of the content I can copy ? or should I just start from scratch? Cheers hRggeNE

Opinion on Duplicate Content Scenario
So there are 2 pest control companies owned by the same person - Sovereign and Southern. (The two companies serve different markets) They have two different website URLs, but the website code is actually all the same....the code is hosted in one place....it just uses an if/else structure with dynamic php which determines whether the user sees the Sovereign site or the Southern site....know what I am saying? Here are the two sites: www.sovereignpestcontrol.com and www.southernpestcontrol.com. This is a duplicate content SEO nightmare, right?

Does duplicate content penalize the whole site or just the pages affected?
I am trying to assess the impact of duplicate content on our e-commerce site and I need to know if the duplicate content is affecting only the pages that contain the dupe content or does it affect the whole site? In Google that is. But of course. Lol

Duplicate content
I run about 10 sites and most of them seemed to fall foul of the penguin update and even though I have never sought inorganic links I have been frantically searching for a link based answer since April. However since asking a question here I have been pointed in another direction by one of your contributors. It seems At least 6 of my sites have duplicate content issues. If you search Google for "We have selected nearly 200 pictures of short haircuts and hair styles in 16 galleries" which is the first bit of text from the site short-hairstyles.com about 30000 results appear. I don't know where they're from nor why anyone would want to do this. I presume its automated since there is so much of it. I have decided to redo the content. So I guess (hope) at some point in the future the duplicate nature will be flushed from Google's index? But how do I prevent it happening again? It's impractical to redo the content every month or so. For example if you search for "This facility is written in Flash® to use it you need to have Flash® installed." from another of my sites that I coincidently uploaded a new page to a couple of days ago, only the duplicate content shows up not my original site. So whoever is doing this is finding new stuff on my site and getting it indexed on google before even google sees it on my site! Thanks, Ian

Load balancing - duplicate content?
Our site switches between www1 and www2 depending on the server load, so (the way I understand it at least) we have two versions of the site. My question is whether the search engines will consider this as duplicate content, and if so, what sort of impact can this have on our SEO efforts? I don't think we've been penalised, (we're still ranking) but our rankings probably aren't as strong as they should be. The SERPs show a mixture of www1 and www2 content when I do a branded search. Also, when I try to use any SEO tools that involve a site crawl I usually encounter problems. Any help is much appreciated!
