Following their usual practice, search engine land's editorial team then reviewed the survey results, added their own contributions, and produced an updated periodic table and explanatory material, which can be viewed and downloaded here.

The common theme throughout the email list discussion, and in the updated periodic table itself, was the importance of relevant, high-quality content, provided to users in a well-structured and easy-to-digest format, in emphasizing convenience. As schwartz noted in his introductory remarks, in the contest between content and links, it is now established that content is more important. Content is, of course, one of the email list main success factor categories in the chart, and has been in previous editions as well. In the first part of their discussion, the panel discussed these content-focused factors, with schwartz noting that google is very good at determining the authority of sources, especially in verticals where authority is particularly important, such as healthcare. Bowman emphasized the importance of training your writing staff to produce high-quality content that is at least as good if not better than your nearest competitors. Johnson reminded us that google's increasingly sophisticated use of machine learning and neural networks allows the company to understand content at a conceptual level.
