I worked in E-Business as part of placement year and I was tasked with project managing the launch of a global online digital asset manager.
So basically a CMS which housed images and marketing collateral and which needed to be easily accessible.
This introduced me into the broad idea of information retrieval and more practically optimising data for search.
Although you had to login to search and it was restricted to employees only, anyone could visit the site.
As you can undoubtedly know, most people don’t actually type urls in but search Google, and hence the “oh shit why can’t people find it” SEO epiphany…
