The verdict

BidX wins, 6.9 to 6.0

BidX and Sellozo both run Amazon ads with dayparting, a rule builder and automatic negative keyword exclusion. BidX also covers Amazon DSP, which Sellozo does not, but its price is in euros, scales with ad spend and needs an annual commitment, with a paid proof of concept instead of a free trial. Sellozo charges a flat rate from $250 a month with a 30 day trial and no minimum term.

Pick BidX if you need Amazon DSP and accept euro pricing and an annual term.

Pick Sellozo if you want a flat rate, a free trial and no annual lock-in.
