Exercise 0.A - Three real accounts, read cold
Choose three real businesses near you that you have never worked with. A restaurant, a salon, a school, a clothing shop, a bakery, a computer shop or similar. Look at each one's social media without reading any of their marketing material first.
For each, record what it sells, who appears to follow it, what it publishes, and one thing it could improve. Then record something harder: for the three most recent posts on each account, name which of the four jobs each post is doing, or record that it is doing none. Expect a significant proportion to be doing none.
Produce one table of nine rows. Timebox: ninety minutes. It fails if the improvement column contains generic advice that would apply to any account, such as post more often or use better photographs. An improvement that could be written without looking at the account is not an observation.
