What counts as a work search for weekly certification? - 10 weeks in

The certification asks how many work-search activities I did and I do not know what qualifies. Some days I only network by email or attend a job fair. What do you record?

I record the date, the company, the job title, how I applied and any contact name. It takes a minute each and it covered me when I was asked for proof.

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