What counts as a work search for weekly certification? (update)

I have been applying to about 4 jobs a week as a school bus driver, but I am unsure what my state wants in the log. Some days I only network by email or attend a job fair. What do you record?

Screenshots of the submitted application are handy backup when a posting disappears.

I was asked for my log once, after six months. Having it in a spreadsheet made it painless.
