I plan on writing a PDF e-book. The goal is to acquire links from a wide variety of governmental websites, as I've noticed they often use PDF's here in my home country (Denmark).
I see a lot of different ways to acquire the links, so I am just wondering, how you see the SEO benefit from each of them.
...Below are the 3 ways of linking I see. If you see any other, please let me know! :-)
1) They take my PDF and upload to to their website. I get a link back because I included a link in the PDF itself
- Pro: Should be the easiest way to convince them of linking, as I don't have to ask specifically for a link
- Con: The link is coming from the PDF = exact same content spread across many websites. Would Google even give value to this link? What are your thoughts?
2) They link to the PDF file on my domain
- Pro: Still relatively easy to convince them to do, as I just send them a link to the PDF.
- Con: I am unsure as to how much links to a PDF benefits my domain, but it's more or less treated the same as links to any other pages, isn't it?
3) They do 2 or 3 and in addition to this I ask for a link citing me as the source right after where they link to the pdf ("Source: [LINK TO MY WEBSITE]")
- Pro: Seems like this would definitely be the strongest type of links, as the links I get would be very varied in nature and go back to a html page.
- Con: People might be a bit more on the fence about linking.
What are your thoughts? What is the best strategy for PDF linkbuilding in your opinion?
