neel Not a stupid question, and no. The only account you actually need is a Facebook Page tied to a company. A personal social profile has nothing to do with it.
Step 1, barebones: get admin access to your company's existing ad account and spend an hour just reading it. Last 90 days, look at what campaigns ran, what objective each one used, and cost per result.

Step 3: Meta Blueprint is free and gets you what you need in a few hours. Skip the paid cert unless someone's making you get it.
