What counts as a work search for weekly certification? - 9 months and counting

The certification asks how many work-search activities I did and I do not know what qualifies. I do not usually post, so bear with me. Some days I only network by email or attend a job fair. Has anyone been audited?

Thanks for writing this out. I went through something close to it 9 months ago, and it got easier once I kept a simple log of every call and form.

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.
