## What agencies should check

1. **Seats.** Per-seat prices grow with every strategist, editor and client login.
2. **Client separation.** Can one client's boards and data stay apart from another's?
3. **Sharing.** Can you share a board or report with a client without a paid seat?
4. **Coverage.** Test with your clients' markets, especially India and the Gulf.
5. **Own-account data.** Pitches land better when competitor ads sit next to the client's own results.

## BigSpy

## FAQ

### Do agencies need a paid tool?

Small agencies can start with free ad libraries. Paid tools pay off when tracking many brands for many clients takes hours each week.

### Can I share boards with clients?

Most tools allow sharing links. Check whether the client needs a paid seat to view.
