Short Answer: When to Use CM360 vs AI Ad Builders

If you’re running large, multi-market display campaigns, you need two different layers:

• Campaign Manager 360 (CM360): Best for ad management, trafficking, verification, and reporting. It’s where creatives go to be served, targeted, and measured, not where they’re made.

• AI ad builders like Viewst: Best for creative production — resizing, animating, versioning, localization, and approvals at scale.

CM360 is your ad operations backbone. Viewst is your HTML5-native production studio that sits between design tools (Figma, Adobe) and ad servers (CM360, DV360, other DSPs).

You get the most value when they work together: CM360 handles trafficking and reporting; Viewst handles banner production at scale.

The Criteria That Actually Decide the Choice

Before comparing CM360 and AI ad builders, it helps to define the criteria that matter for high-volume campaigns:

1. Core job of the platform – Is it built for trafficking or for creative production?

2. HTML5 creative capabilities – Can you design, animate, and edit HTML5 banners natively?

3. Scaling and versioning – How quickly can you go from one master to dozens of sizes and variants?

4. Brand governance and risk control – How well are brandbooks, typography, and colors enforced?

5. Collaboration and approvals – Where does feedback live, and how structured is the review flow?

6. Integration with ad servers and DSPs – How clean is the handoff into CM360, DV360, and other media platforms?

7. AI approach and ethics – Is AI used to replace creative judgment or remove mechanical work?

8. Best-fit use cases – Which teams and scenarios each platform truly serves.

We’ll compare CM360, Viewst, and the broader AI ad builder category across these criteria, then close with use-case-specific recommendations.

Comparison Table: CM360 vs Viewst vs AI Ad Builders

1. Core Job of the Platform

CM360: Trafficking and Ad Operations, Not Production

Google’s own documentation is clear: Campaign Manager 360 is a web-based ad management system for advertisers and agencies.

It is built to:

• Upload creatives as ZIP/ADZ files

• Set targeting, frequency capping, and placements

• Manage campaigns and flights

• Verify tags and viewability

• Report on impressions, clicks, and conversions

It is not built to:

• Design creatives

• Animate HTML5 banners

• Manage production workflows

Historically, the old DoubleClick stack separated these jobs:

• DoubleClick Digital Marketing Manager (now CM360) handled trafficking/reporting.

• DoubleClick Studio handled rich media production and workflow.

CM360 inherited the trafficking side, not the studio side. That matters when you’re deciding what tool to use for creative work.

Viewst and AI Ad Builders: Production Studios, Not Ad Servers

Platforms like Viewst, Celtra, Bannerflow, Storyteq, and Hunch are positioned as creative production and automation environments:

• They assume your ad server or campaign manager is somewhere else.

• Their job is to turn creative ideas into scalable, ready-to-traffic assets.

Viewst in particular frames itself as “production infrastructure for creative and advertising teams” — explicitly not an ad serving platform.

If you try to use CM360 as a creative studio, you’ll hit walls immediately. If you try to use an AI ad builder as your trafficking system, you’ll miss the depth of CM360’s ad operations.

You need both layers, not one.

2. HTML5 Creative Capabilities

What CM360 Can and Cannot Do with HTML5

For HTML5 display creatives, CM360 expects:

• ZIP/ADZ packages with up to 100 files

• Max creative size around 9.5 MB per asset

• Assets built in Google Web Designer or another HTML5 editor

CM360:

• Validates that the creative meets file size and format requirements

• Hosts the creative and serves it in placements

But CM360 does not let you:

• Edit HTML5 layers

• Adjust animation timelines

• Change copy or layout

• Build new versions and sizes directly inside the platform

It is upload-oriented, not creation-oriented.

Viewst: HTML5-Native, WYSIWYG Production Environment

Viewst is built around native editable HTML5:

• True WYSIWYG editor — what you see in the studio is what ships in the ad.

• AI Designer — prompts into structured HTML5 banner sets.

• AI Instant Animator — one-click motion across layers, not canned templates.

• AI Image Deflatening — turns flat assets (e.g., PNG exports, older banners) into editable designs.

You can:

• Import from Figma and Adobe

• Work in layers, timelines, and reusable components

• Export HTML5/GIF/MP4 ad-ready files

Other AI ad builders offer HTML5 support, but many are:

• More template-driven, especially for social formats

• Less focused on deep HTML5 layer editing

If your team cares about craft-level control in HTML5 — not just templates — CM360 is not the place for that. Viewst is.

3. Scaling, Resizing, and Versioning

The Scale Problem: Designers Drowning in Repetitive Work

Recent research shows how big the production burden has become:

• Adobe’s 2024 State of Creativity: creative teams spend 21+ hours/week on repetitive design tasks; 71% have project management challenges.

• Monotype’s 2025 report: 57% of creative professionals spend more than 25% of their time on non-creative tasks.

• A 2023 survey of 350+ designers: 85% struggle with resizing graphics, and 76% of those spend at least 20 hours/week on resizing.

At the same time:

• Adobe’s 2025 marketer research: 96% of marketers saw content demand at least 2x higher in two years, 62% saw 5x+ growth, and 71% expect it to increase 5x+ again by 2027.

Without automation, high-volume banner sets turn into production bottlenecks and designer burnout.

CM360’s Role: Zero Help on Scaling

CM360 doesn’t touch resizing or versioning.

All of this happens before files are uploaded:

• Designers create sizes in Figma/Adobe.

• They export and package each size as HTML5.

• They send ZIPs to operations for trafficking.

Every new size, language, or offer means starting over.

Viewst: Master-Creative-Driven Scaling

Viewst is built for exactly this problem:

• AI Smart Resize — generate all required sizes from one master creative.

• Master creative acts as single source of truth; updates sync across all sizes.

• Versioning built in for offers, audiences, markets, and tests.

This matters for:

• Programmatic display with dozens of placements per campaign.

• Retail media environments with many retailer-specific specs.

• Performance campaigns that need frequent creative iteration and A/B testing.

Other AI ad builders (Celtra, Bannerflow, Storyteq):

• Also focus on creative automation and dynamic variation.

• Often extend beyond display into video and social.

They may be a better fit if you need end-to-end cross-channel variation. Viewst is strongest where HTML5 display sets are the core friction.

4. Brand Governance and Risk Control

What CM360 Enforces

CM360 enforces ad-serving rules, not creative rules:

• Placement restrictions

• Geo and audience targeting

• Frequency capping

• Verification tags and brand safety controls at placement level

It does not:

• Validate brand fonts and colors

• Lock layout or logo usage

• Govern local market adaptations inside the creative itself

Brand risk inside the creative layer still depends on how and where creatives are produced.

Viewst: Brandbooks Inside the Production Layer

Viewst treats brand control as non-negotiable:

• Brandbooks define locked typography, color systems, spacing, and logo usage.

• Styles propagate across:

  • All sizes generated from the master creative

  • All markets, languages, and versions

  • All team members working in the platform

Automation reinforces the brand, rather than undermining it.

Other AI ad builders:

• Many offer brand libraries, templates, and locked elements, especially at enterprise tier.

• The depth and rigor of enforcement varies significantly.

If you’re concerned about local teams editing banners off-template or freelancers introducing visual drift, CM360 alone won’t help. A production layer with brand governance (like Viewst) will.

5. Collaboration and Approvals

The Reality Today: Feedback Everywhere, Not Anywhere Useful

Most teams still manage creative feedback via:

• Screenshots in email

• Links in Slack or Teams

• PDF decks and PowerPoints

• Comment threads in Figma outside the ad-ready context

Adobe’s 2024 research found 71% of creative teams report project-management challenges — scattered approvals are a major part of that.

CM360’s Collaboration Model

CM360’s collaboration is designed for traffickers and media ops, not creative review:

• Users can see which creatives are attached to which placements.

• Ops teams can check status, QA, and trafficking details.

But creative stakeholders rarely do visual review inside CM360. By the time a creative is in CM360, it’s usually considered final.

Viewst: Review Inside the Banner Set

Viewst embeds collaboration directly in the production environment:

• Stakeholders comment on specific banners and sizes.

• Previews are shareable without exporting screenshots.

• Approvals can be captured and tracked inside the production set.

This keeps:

• Feedback where creatives are actually made

• A single source of truth for which version is approved

Other AI ad builders:

• Many include online proofing, comments, and approval workflows.

• Some tie approvals into activation (publishing creatives straight to channels).

The key distinction: CM360 is a destination for approved creatives; Viewst and peers are where the approvals happen.

6. Integration with Ad Servers and DSPs

CM360: The Ad Management Hub

CM360 is usually the central hub for:

• Ad tags and placements

• Cross-channel reporting

• Verification and attribution

For Google-centric stacks, it sits alongside:

• DV360 for programmatic buying

• Google Ads for search, YouTube, and some display

Creatives come into CM360 from external production tools, then flow out to media platforms.

Viewst: Sitting Between Design and Media

Viewst is built to slot cleanly into this ecosystem:

• Imports from Figma and Adobe so designers work where they’re comfortable.

• Exports production-ready HTML5, GIF, and MP4.

• Files are packaged in formats CM360 expects (e.g., ZIP/ADZ for HTML5).

The result:

• Creative teams own design and production.

• Ad operations teams own trafficking in CM360.

• Hand-off is structured and predictable, not a patchwork of files and folders.

Other AI ad builders:

• Often integrate directly with social APIs, ad servers, and DCO platforms.

• Some promise “build and publish” flows — useful for performance teams but sometimes less aligned with enterprise separation of duties.

For large organizations where media ops and creative ops are distinct, Viewst’s “between design and CM360” positioning is often more comfortable.

7. AI Approach and Ethics

How AI Is Actually Used in Creative Operations

Across Adobe’s 2024 and 2026 research:

• 83% of creative professionals already use generative AI at work.

• 66% say it helps them make better content; 58% say they create more.

• 87% of creators say creative AI accelerates business or audience growth.

• 85% believe the final creative decision should remain theirs.

The emerging consensus: AI should remove monotonous tasks and amplify human creativity, not replace creative judgment.

CM360: Little to No AI in Production

CM360’s AI is focused on:

• Optimization and attribution

• Viewability and fraud detection

It does not offer AI tools for:

• Designing creatives

• Resizing or animating banners

Viewst: AI for Production, Not Replacement

Viewst’s AI features are explicitly aimed at non-creative suffering:

• AI Smart Resize – avoids manual resizing.

• AI Image Deflatening – turns flat assets into editable layers.

• AI Designer – turns prompts into structured HTML5, which designers can refine.

• AI Instant Animator – builds motion from existing layers.

The final decisions — layouts, message hierarchy, visual nuance — stay with designers. AI handles the mechanical work at scale.

Other AI ad builders:

• Mix generative AI (image/video generation from prompts) with templated automation.

• Some skew heavily towards performance marketing teams who value speed over nuance.

If you want AI that respects brand standards and creative expertise, Viewst — and similar infrastructure-focused platforms — fit better than generic AI image generators.

8. Best-Fit Use Cases

When CM360 Is the Right Tool

Use CM360 when your primary job is:

• Trafficking large, complex campaigns with many placements.

• Managing ad tags across publishers and platforms.

• Ensuring QA, viewability, and compliance.

• Reporting across channels and campaigns.

CM360 is a must-have ad operations system, especially for:

• Enterprise advertisers

• Agencies running multi-client campaigns

It is not a creative production studio.

When Viewst Is the Right Tool

Use Viewst when your primary job is:

• Building and maintaining large sets of HTML5 display ads.

• Scaling one master concept into dozens of sizes and dozens of variants.

• Keeping brandbooks locked while still enabling local adaptations.

• Shortening creative iteration loops for performance and growth teams.

Viewst is particularly strong for:

• Digital, performance, and media agencies.

• Mid-market to enterprise brands with 20+ person marketing/creative teams.

• Businesses where programmatic display and retail media are core channels.

When Other AI Ad Builders Make Sense

Consider tools like Celtra, Bannerflow, Storyteq, or Hunch when:

• You need cross-channel asset automation (display, social, video, DOOH).

• You want activation plus production in one platform.

• You run dynamic creative optimization (DCO) at scale.

Vendor-reported proof points (not independently audited) include:

• Celtra: teams generating ads 5x faster, with one Nike case citing 19.5% higher production efficiency.

• Storyteq: Heineken reporting 40% lower content production costs while scaling to 160 countries.

These platforms can be excellent for omnichannel creative automation. Viewst is more targeted: deep HTML5 production between design and CM360.

Result:

• Specialized tools for each layer, stitched together via clear workflows.

FAQ: Buying Questions Creative and Operations Leads Ask

1. Can CM360 replace a creative production platform?

No. CM360 is designed for ad management, trafficking, verification, and reporting. It expects creatives to arrive as packaged files (ZIP/ADZ for HTML5) built elsewhere. It doesn’t provide tools for designing, animating, or versioning creatives.

2. Do we still need Figma or Adobe if we use Viewst?

Yes. Viewst is not a replacement for core design tools. Designers still use Figma or Adobe to create master concepts and visual systems. Viewst sits after those tools, turning master designs into scalable, animated, ad-ready HTML5 sets.

3. How does Viewst integrate with CM360 in practice?

Viewst outputs production-ready HTML5, GIF, and MP4 files that align with CM360’s creative specifications. Teams:

• Import assets from Figma/Adobe into Viewst.

• Build and scale banners in Viewst.

• Export packaged creatives (e.g., ZIPs) to upload into CM360 for trafficking and reporting.

4. What about brand safety and compliance — CM360 or Viewst?

Both, at different layers:

• CM360 handles placement-level brand safety (verification tags, viewability, fraud checks).

• Viewst enforces creative-level brand control (fonts, colors, logos, layouts) via brandbooks and locked styles.

You need both to manage risk end-to-end.

5. How do AI ad builders affect designer roles and burnout?

Research from Adobe and Monotype shows creative teams spend a large share of time on non-creative, repetitive tasks, and that AI/automation can significantly improve efficiency:

• 62% of teams using AI report boosts in efficiency and creativity.

Platforms like Viewst are designed to:

• Remove mechanical work (resizing, exports, basic animation).

• Leave creative judgment and final decisions with designers.

The goal is not to replace designers, but to reduce non-creative suffering so they can focus on higher-value work.

By treating CM360 as your ad operations layer and Viewst as your HTML5 production infrastructure, you get a workflow that respects creative craft, scales output, and keeps brand and operational risk under control.
