As I mentioned above, SEO is always changing. Tom Demers used to come in early every morning and spend an hour or so just reading. Keeping up with the industry is crucial both to stay current on news and various Google updates as well as to get new strategic ideas and tips for increasing efficiency. So I ask job candidates to tell me what SEO blogs and sites they read. But anyone can list out a few blogs. I'm looking for something beyond the bare-minimum basics (like Search Engine Land). I then follow up with another question: What's an interesting article you've recently read on one of those blogs and why did you find it interesting? This tells me whether they actually read any blogs, how often, as well as why they read.
