The Problem
Marketplace advertising is no longer optional — it's the cost of visibility. But managing PPC across Amazon Sponsored Products, Walmart Connect, and eBay Promoted Listings means juggling separate dashboards, different bidding strategies, and fragmented performance data. Amazon's suggested bids optimize for their auction, not your margins. Manual bid adjustments can't keep pace with hourly market shifts. And when your ACOS spikes, you can't tell whether the problem is your bids, your keywords, or the listing behind the ad.
