From a recent project run for Masters in Digital Marketing students at Hult in conjunction with Greenlight, the SEO specialists, one of the key learnings for students was how to build links and the importance of link equity for SEO.

It is, therefore, always nice to see learning in practice - and this embeddable widget from OnlinePhD.org is a fine example of how to do it.  Their simple graphic was on Mashable and shared from Mashable's pages over 1000 times - and each embedded copy of the widget will include (if not explicitly deleted) a link to OnlinePhD - thereby making the site more popular in the eyes of the great Google and, therefore, more likely to increase its Google rank.

So, since it is useful, and to remind myself in the future how to get better results from Google, I have also embedded it here. Kudos to OnlinePhD (or their SEO advisers).

UPDATE: In January 2013 OnlinePhD.org contacted me asking me to remove the links in this blog to their site as they are accused of Google of 'over-optimising'.  Hmm... strange...but always one to oblige...the links have been removed...
