Celtra

What it does

Celtra is a Creative Management Platform (CMP) used by creative and media teams to design, scale and activate digital ad formats without constant file round trips. Teams use it to build reusable templates, automate catalog-driven creatives, and deliver assets to ad servers and DSPs. Creative authoring and templates Celtra provides a browser-based creative builder and reusable templates for HTML5, video and rich-media formats so teams can create a master creative and produce many on‑brand variants. The in-platform editor reduces dependence on native source files by enabling edits and versioning inside the CMP. Creative automation and dynamic product ads The platform supports data-driven templates and catalog-fed workflows for dynamic creative optimization (DCO) and catalog/retail ads. Users can map product feeds, apply business rules or logic, and generate large numbers of adapted creatives for markets, languages and formats. Activation, tags and integrations Celtra can generate platform-ready tags and supports pushing creatives to ad servers and DSPs; the vendor documents a tag generator and a supplier/certification list for integrations such as Google Campaign Manager and other certified partners. Integration capabilities vary by certified publisher. Analytics, testing and creative insights Built-in reporting, variant testing workflows and creative performance scoring help connect creative output to media performance. Celtra also publishes Creative Insights reports and provides in-platform metrics to compare creative variants and inform iteration. Technical constraints and integration notes Product documentation specifies accepted asset types, encoding and file-size limits for video and other assets, and notes that some publisher integrations require explicit certification.
