PDF for link building - avoiding duplicate content
-
Hello,
We've got an article that we're turning into a PDF. Both the article and the PDF will be on our site. This PDF is a good, thorough piece of content on how to choose a product.
We're going to strip out all of the links to our in the article and create this PDF so that it will be good for people to reference and even print. Then we're going to do link building through outreach since people will find the article and PDF useful.
My question is, how do I use rel="canonical" to make sure that the article and PDF aren't duplicate content?
Thanks.

Hey Bob
I think you should forget about any kind of perceived conventions and have whatever you think works best for your users and goals.
Again, look at unbounce, that is a custom landing page with a homepage link (to share the love) but not the general site navigation.
They also have a footer to do a bit more link love but really, do what works for you.
Forget conventions - do what works!
Hope that helps

I see, thanks! I think it's important not to have the ecommerce navigation on the page promoting the pdf. What would you say is ideal as far as the graphical and navigation components of the page with the PDF on it - what kind of navigation and graphical header should I have on it?

Yep, check the HTTP headers with webbug or there are a bunch of browser plugins that will let you see the headers for the document.
That said, I would push to drive the links to the page though rather than the document itself and just create a nice page that houses the document and make that the link target.
You could even make the PDF link only available by email once they have singed up or some such as canonical is only a directive and you would still be better getting those links flooding into a real page on the site.
You could even offer up some HTML to make this easier for folks to link to that linked to your main page. If you take a look at any savvy infographics etc folks will try to draw a link into a page rather than the image itself for the very same reasons.
If you look at something like the Noobs Guide to Online Marketing from Unbounce then you will see something like this as the suggested linking code:

[](<strong>http://unbounce.com/noob-guide-to-online-marketing-infographic/</strong>)
Unbounce – The DIY Landing Page Platform
So, the image is there but the link they are pimping is a standard page:
http://unbounce.com/noob-guide-to-online-marketing-infographic/
They also cheekily add an extra homepage link in as well with some keywords and the brand so if folks don't remove that they still get that benefit.
Ultimately, it means that when links flood into the site they benefit the whole site rather than just promote one PDF.
Just my tuppence!

Thanks for the code Marcus.
Actually, the pdf is what people will be linking to. It's a guide for websites. I think the PDF will be much easier to promote than the article.I assume so anyway.
Is there a way to make sure my canonical code in htaccess is working after I insert the code?
Thanks again,
Bob

Hey Bob
There is a much easier way to do this and simply have your PDFs that you don't want indexed in a folder that you block access to in robots.txt. This way you can just drop PDFs into articles and link to them knowing full well these pages will not be indexed.
Assuming you had a PDF called article.pdf in a folder called pdfs/ then the following would prevent indexation.
User-agent: * Disallow: /pdfs/
Or to just block the file itself:
User-agent: *
Disallow: /pdfs/yourfile.pdf Additionally, There is no reason not to add the canonical link as well and if you find people are linking directly to the PDF then having this would ensure that the equity associated with those links was correctly attributed to the parent page (always a good thing).Header add Link '<http: www.url.co.uk="" pdfs="" article.html="">; </http:> rel="canonical"'
Generally, there are better ways to block indexation than with robots.txt but in the case of PDFs, we really don't want these files indexed as they make for such poor landing pages (no navigation) and we certainly want to remove any competition or duplication between the page and the PDF so in this case, it makes for a quick, painless and suitable solution.
Hope that helps!

Thanks ThompsonPaul,
Say the pdf is located at
domain.com/pdfs/white-papers.pdf
and the article that I want to rank is at
domain.com/articles/article.html
do I simply add this to my htaccess file?:
Header add Link "<http: www.domain.com="" articles="" article.html="">; rel="canonical""</http:>
-
You can insert the canonical header link using your site's .htaccess file, Bob. I'm sure Hostgator provides access to the htaccess file through ftp (sometimes you have to turn on "show hidden files") or through the file manager built into your cPanel.
Check tip #2 in this recent SEOMoz blog article for specifics:
seomoz.org/blog/htaccess-file-snippets-for-seosJust remember too - you will want to do the same kind of on-page optimization for the PDF as you do for regular pages.
- Give it a good, descriptive, keyword-appropriate, dash-separated file name. (essential for usability as well, since it will become the title of the icon when saved to someone's desktop)
- Fill out the metadata for the PDF, especially the Title and Description. In Acrobat it's under File -> Properties -> Description tab (to get the meta-description itself, you'll need to click on the Additional Metadata button)
I'd be tempted to build the links to the html page as much as possible as those will directly help ranking, unlike the PDF's inbound links which will have to pass their link juice through the canonical, assuming you're using it. Plus, the visitor will get a preview of the PDF's content and context from the rest of your site which which may increase trust and engender further engagement..
Your comment about links in the PDF got kind of muddled, but you'll definitely want to make certain there are good links and calls to action back to your website within the PDF - preferably on each page. Otherwise there's no clear "next step" for users reading the PDF back to a purchase on your site. Make sure to put Analytics tracking tags on these links so you can assess the value of traffic generated back from the PDF - otherwise the traffic will just appear as Direct in your Analytics.
Hope that all helps;
Paul

Can I just use htaccess?
See here: http://www.seomoz.org/blog/how-to-advanced-relcanonical-http-headers
We only have one pdf like this right now and we plan to have no more than five.
Say the pdf is located at
domain.com/pdfs/white-papers.pdf
and the article that I want to rank is at
domain.com/articles/article.pdf
do I simply add this to my htaccess file?:
Header add Link "<http: www.domain.com="" articles="" article.pdf="">; rel="canonical""</http:>

How do I know if I can do an HTTP header request? I'm using shared hosting through hostgator.

PDF seem to not rank as well as other normal webpages. They still rank do not get me wrong, we have over 100 pdf pages that get traffic for us. The main version is really up to you, what do you want to show in the search results. I think it would be easier to rank for a normal webpage though. If you are doing a rel="canonical" it will pass most of the link juice, not all but most.

Thank you DoRM,
I assume that the PDF is what I want to be the main version since that is what I'll be marketing, but I could be wrong? What if I get backlinks to both pages, will both sets of backlinks count?

Indicate the canonical version of a URL by responding with the
Link rel="canonical"
HTTP header. Addingrel="canonical"
to thehead
section 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:>
Google currently supports these link header elements for Web Search only.

Same site serving multiple countries and duplicated content
Hello! Though I browse MoZ resources every day, I've decided to directly ask you a question despite the numerous questions (and answers!) about this topic as there are few specific variants each time: I've a site serving content (and products) to different countries built using subfolders (1 subfolder per country). Basically, it looks like this:
Intermediate & Advanced SEO | | GhillC
site.com/us/
site.com/gb/
site.com/fr/
site.com/it/
etc. The first problem was fairly easy to solve:
Avoid duplicated content issues across the board considering that both the ecommerce part of the site and the blog bit are being replicated for each subfolders in their own language. Correct me if I'm wrong but using our copywriters to translate the content and adding the right hreflang tags should do. But then comes the second problem: how to deal with duplicated content when it's written in the same language? E.g. /us/, /gb/, /au/ and so on.
Given the following requirements/constraints, I can't see any positive resolution to this issue:
1. Need for such structure to be maintained (it's not possible to consolidate same language within one single subfolders for example),
2. Articles from one subfolder to another can't be canonicalized as it would mess up with our internal tracking tools,
3. The amount of content being published prevents us to get bespoke content for each region of the world with the same spoken language. Given those constraints, I can't see a way to solve that out and it seems that I'm cursed to live with those duplicated content red flags right up my nose.
Am I right or can you think about anything to sort that out? Many thanks,

OSE - How to determine good links to build on...?
Hey Guys, Weather it be OSE, ahrefs, etc. How do you determine if the link is worth using to build a backlink on? I know to look for a higher DA/PA and overall established links. I want very quality sites for external links (as we all do) but I also want to know what to look for and what to bypass when determining if I should build a backlink on the domain. These are a Few examples / questions i have sorry if they are basic: (the below are all specific examples) 1. If a site has an article and that article page is a DA 65 / PA 1 with Zero (0) established links to that article my backlink is on; would it be link building worthy? Should I leave a backlink, why? ex. lots of different blogspot.com blogs pointing back at my site..^^ Same domian, different blog any benefit? 2. If a site is a PR2 DA 30/ PA 32 with 14 root domains, 250 total links.... Would a link like this give me any benefit or should I skip links like this? Why? 3. What main factors do you focus on/look for and know when & when not leave a backlink to your site when using a tool like OSE, Ahrefs? 4. Should I even worry about a sites PR when linkbuilding since PR doesnt play that big of a role anymore opposed to high quality backlinks? Ive seen PR 7 sites outranked by PR1 site with 200 high quality backlinks to it Thanks for any help and any help is GREATLY appreciated. 🙂

Do links to PDF's on my site pass "link juice"?
Hi, I have recently started a project on one of my sites, working with a branch of the U.S. government, where I will be hosting and publishing some of their PDF documents for free for people to use. The great SEO side of this is that they link to my site. The thing is, they are linking directly to the PDF files themselves, not the page with the link to the PDF files. So my question is, does that give me any SEO benefit? While the PDF is hosted on my site, there are no links in it that would allow a spider to start from the PDF and crawl the rest of my site. So do I get any benefit from these great links? If not, does anybody have any suggestions on how I could get credit for them. Keep in mind that editing the PDF's are not allowed by the government. Thanks.

Building High PR Links
Would this technique work well for ranking? Get a relevant guestpost on a relevant site. Then send high PR links to that page to create pr3-5 relevant links to your main site.

Link Building Question
Hey Moz'ers, I have created several blogs on different domains for the purpose of writing good content articles that contain 2-3 links per article that go back to my website. It has been up for about 3-4 weeks. I am not seeing my results/links showing up in OSE, is this because it still needs more time or is there something else I could be advised to look into? In theory these blogs will only contain 2-3 links from each domain to the site. I was also going to make sure the anchor text per link is different (keyword, brand name, random anchor like click here). Side note: How does this system sound as part of one small aspect to link building? red flags? Thanks for all the responses and advice.

Link Building with PRweb press releases
Im looking for tips or best practices when sending out PR for link building. I send out at least 4 press releases per month using prweb’s advanced release which allows anchor text. For the past few months I’ve been rotating branded terms, exact match keywords and full URL’s as the links, but always linking to my home page or to one particular subpage. Most of the releases are to announce upcoming projects or to announce a recent website launch for a client, less often we’re highlighting a service or special we want to promote. Im wondering if I should be linking to more sub pages to spread links around, and if I should be focusing more on branded terms vs. exact match anchors. Due to the cost involved I just want to be sure im getting the most out of it.

Duplicate Content Warning For Pages That Do Not Exist
Hi Guys I am hoping someone can help me out here. I have had a new site built with a unique theme and using wordpress as the CMS. Everything was going fine but after checking webmaster tools today I noticed something that I just cannot get my head around. Basically I am getting warnings of Duplicate page warnings on a couple of things. 1 of which i think i can understand but do not know how to get the warning to go. Firstly I get this warning of duplicate meta desciption url 1: / url 2: /about/who-we-are I understand this as the who-we-are page is set as the homepage through the wordpress reading settings. But is there a way to make the dup meta description warning disappear The second one I am getting is the following: /services/57/ /services/ Both urls lead to the same place although I have never created the services/57/ page the services/57/ page does not show on the xml sitemap but Google obviously see it because it is a warning in webmaster tools. If I press edit on services/57/ page it just goes to edit the /services/ page/ is there a way I can remove the /57/ page safely or a method to ensure Google at least does not see this. Probably a silly question but I cannot find a real comprehensive answer to sorting this. Thanks in advance

Affiliate Site Duplicate Content Question
Hi Guys I have been un-able to find a definite answer to this on various forums, your views on this will be very valuable. I am doing a few Amazon affiliate sites and will be pulling in product data from Amazon via a Wordpress plugin. The plugin pulls in titles, descriptions, images, prices etc, however this presents a duplicate content issue and hence I can not publish the product pages with amazon descriptions. Due to the large number of products, it is not feasible to re-write all descriptions, but I plan re-write descriptions and titles for 50% of the products and publish then with “index, follow” attribute. However, for the other 50%, what would be the best way to handle them? Should I publish them as “noindex,follow”? **- Or is there another solution? Many thanks for your time.**
