Last year, Google finally gave confirmation that .edu links are no more valuable than .com links. However, that doesn’t mean we should just forget them, because the academic world is yet another target audience, and a link from a .edu or .ac.uk site will bring your website and its content to the attention of yet more people.
There is a great article on how to get .edu links which is worth a read to think out of the box a little for link building ideas anyway.
Your link building strategy should seek high quality links at all times, but in order to get academic links you will need to provide quality content. because of course CONTENT IS KING!
