Understanding digital footprints is helped by at least a basic understanding of search engine optimization, something I’ve gained from a career in web development. Google’s major innovation was the PageRank algorithm, “a method for rating Web pages objectively and mechanically, effectively measuring the human interest and attention devoted to them.” Dramatically oversimplified, PageRank considers the relative importance of each page and passes that rank through to all the pages that are hyperlinked from that page–simulating the importance that a standard user would give to the links from that page. Since that time, the major search engines have adopted similar search algorithms and built upon that.
What that means for building a digital footprint is that there is, in fact, a way to build a digital presence by focusing on developing and being linked to from highly-ranked sites (like schools and colleges). Social media sites also tend to pass ranking, meaning that an ePortfolio, linked to from academic sites and regular postings from social media, is an excellent way to build a digital identity.
