What counts as a work search for weekly certification? - 17 weeks in

The certification asks how many work-search activities I did and I do not know what qualifies. This is my first time dealing with any of this. Some days I only network by email or attend a job fair. What do you record?

Keep everything in writing and save the confirmation numbers. It saved me later.

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.
