Lucy is a content marketer and SEO and works at the great UK agency https://www.evolvedsearch.co.uk/. Lucy talked at Brighton SEO, the Best SEO and marketing conference around. (seriously guys, I can't make his more obvious, you need to invite me as a speaker to Brighton :D)
Content hubs are something that a lot of companies try to do, but also something that is somehow easy to fail at. Lucy has experience in building them and tells that in detail on how you can do it too. Done correctly, content hubs can be a great addition to your content and a big SEO asset.
