Hi, due to political and compliance concerns at our client's organization, we've decided not to use Google Display Network for our advertising campaigns. We have a monthly budget of around $10,000 and are looking to run display ads targeting a very specific audience—IT professionals and decision-makers interested in data center technology and infrastructure solutions. Ideally, we'd like to manually select website placements or at least target relevant categories or contexts with precision. We've explored AdRoll, but unfortunately, its site-level targeting and placement controls are quite limited for our needs. We're now actively looking for alternative self-serve ad platforms that offer more robust control over audience targeting and placement strategy. Any recommendations for platforms that fit this use case would be greatly appreciated.
