Pretty basic I know, but I'm looking to find out whether or not the applicant has updated what he or she knows about on-site optimisation. Keyword research, title tags, urls, content, alt tags, site structure, navigation, internal linking, site maps, subdomains are all part of what I'm expecting to hear. However, what I don't what to hear is:

☛ Google can't crawl javaScript

☛ Google can't follow JavaScript links

☛ Keyword density must be X percent

☛ Google can't read Ajax

☛ Meta keywords are very important and should spend time including them

☛ Meta descriptions are not so important

If I'm still hearing this kind of things in 2012 it is most likely they may not be right for the top job.
