The Trade Desk scores 5.3 here: it covers multiple channels and offers useful measurement options, but its pricing is too unclear to judge value. The Reddit discussion raises concerns about competition from Amazon and whether TTD has a distinct audience advantage; commenters also push back on the evidence. Those are debated investor claims, not proof that advertisers are leaving. For a switch, start with the job you need done, then ask each vendor for pricing and service terms in writing.

Audience differentiation is questioned
One Reddit thread calls TTD a DSP without an audience, while commenters dispute whether the criticism is supported by evidence.
Amazon competition is debated
A Reddit post argues Amazon is taking share, but commenters cite TTD growth and say the thread offers insufficient evidence.

Is Amazon taking advertisers from The Trade Desk?
