Do I need a separate agency or sub-account for each niche I target?

No. You do not need a different agency for each niche, and often you do not need a different sub-account either. Work in your main agency account, create a snapshot for each solution or niche, and pass the snapshots down to your clients' sub-accounts. Keep the account organized with folders by niche (agents, forms, phone numbers), and build one agent per industry or trade, since for example hail restoration is different from plumbing.

A separate sub-account is optional if you want to keep things apart, but each one means duplicate work: separate social accounts, duplicate assets and everything built again. We still recommend focusing on one niche.
