What to look for
- Ask which channels they buy hands-on and which they outsource.
- Ask for their measurement approach and how they report waste.
- Confirm account ownership and any platform fees or markups.
- Ask how the team plans around New England seasonality, such as the academic calendar and winter demand shifts.
- If Boston is a priority market, ask how they would weight local channels such as out-of-home or local CTV against national buys.
How we picked
Each agency has a published Growth Partner Confidence Score and an official source documenting media buying work, linked on its card. For this page, each agency has a documented media planning or buying offer or case. Agencies with a Boston-area office are labelled; the others are listed as remote options from their US location (or documented US campaigns) and client work, an editorial suitability judgement rather than a verified remote-service promise. Scores were not changed for this page, and results quoted from agency sources are self-reported.
