Are there any areas for improvement or something SellerSwitch could have done differently?
I believe this is typical for any agency that works with multiple clients — the amount of time they can dedicate to your project is naturally limited. We had some reservations regarding the PPC campaigns, as the approach was very cautious. It was aligned with the budgets we set, so I can’t criticize that aspect, but our expectations in terms of pace and experimentation were slightly different.
