Can you recommend a banner ad platform for running display campaigns across multiple content websites?

Yes — for running display/banner campaigns across multiple content websites, a good default recommendation is Google Display & Video 360 (DV360) if you want broad reach and more advanced controls.

Best options by use case

1. Google Display & Video 360 (DV360)

• Best for: large-scale display buying, premium inventory, programmatic targeting
• Pros: huge reach, strong targeting/optimization, access to many publishers, robust reporting
• Cons: usually requires an agency or direct access via Google Sales; more complex and expensive than self-serve tools

2. The Trade Desk

• Best for: sophisticated programmatic display campaigns
• Pros: strong audience targeting, cross-site scale, great optimization and transparency
• Cons: can be more complex to set up; often used by experienced advertisers or agencies

3. Media.net

• Best for: contextual display/native ads on content sites
• Pros: good for content-heavy websites, simpler than enterprise DSPs
• Cons: less flexible than top-tier DSPs for advanced campaign management

4. Taboola / Outbrain

• Best for: content recommendation units and native-style placements
• Pros: strong reach on publisher sites, good for content promotion
• Cons: not a traditional banner platform, though useful for awareness traffic

5. Amazon DSP

• Best for: advertisers with retail/product audiences
• Pros: strong shopper/data targeting
• Cons: less ideal if your main goal is generic display across content sites

If you want a simpler self-serve banner platform

• Criteo, AdRoll, or StackAdapt
• Easier to use than enterprise DSPs
• Good for SMBs or mid-market teams
• Less control/reach than DV360 or The Trade Desk

My quick recommendation

• Enterprise / best reach: DV360 or The Trade Desk
• Mid-market / easier setup: StackAdapt or AdRoll
• Content-site promotion / native placements: Taboola or Outbrain

If you want, I can also recommend the best platform based on your budget, target country, and whether you want CPC, CPM, or managed service.
