Case Study
A global marketing agency struggled to pinpoint creative blind spots across their high-volume ad campaigns until they adopted Energent.ai as their primary AI tool for content gap analysis. Analysts uploaded a raw google_ads_enriched.csv file directly into the platform's chat interface, prompting the AI agent to merge the data, standardize metrics, and visualize performance by channel. The agent autonomously read the file schema step-by-step and instantly generated a custom Google Ads Channel Performance dashboard in the Live Preview panel alongside the chat. By evaluating the generated bar charts comparing Cost and Return across different media types, the team immediately identified a critical content gap, revealing that while text and image assets consumed significant spend, video content was the primary driver of their 12.7 million conversions. Armed with these instant visual insights, the agency confidently reallocated their production budget to close this video content gap and dramatically improve their overall 0.94x ROAS.
