Test which social platform brings you work, with a 4-week tracking sheet

Help me find out which social platform is worth my time.

My business: [what you do and where]
My customers: [e.g. local homeowners aged 35 to 60]
Where I post now and how often: [e.g. Facebook twice a week, Instagram now and then, TikTok never]
Where my last 10 customers came from, if I know: [e.g. 4 word of mouth, 3 Google, 2 Facebook, 1 don't know]
Time I can give a week: [e.g. 1 hour]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. The two platforms to test and why, based on my customers and what I've told you, not general popularity.
2. A 4-week plan with the same number of posts and the same type of content on each, adapted to each platform.
3. A tracking sheet as a table, one row per week per platform: posts, messages, enquiries, bookings and "how did you hear about us?" answers.
4. What counts as a winner after 4 weeks, decided now so I can't fudge it.
5. What to do with the loser: pause it, keep a profile with contact details, or stop.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or results. UK English.
