Lack of Campaign Structure

Naming of campaigns was inconsistent, and there was no unified strategy at play. Hence, tracking performance and optimizing the campaigns was extremely difficult.

Poor Targeting Accuracy

The campaigns were not built around precise audience signals. As a result, ads reached broad, unqualified users, resulting in higher costs and fewer conversions.

BrandLoom addressed creative fatigue in Ashley Stewart’s ads by implementing a creative refresh loop and compliance-focused redesigns

Creative Fatigue

Ads got flagged frequently, and there was a slim selection of creatives to recycle through. So, the campaigns couldn’t adapt or sustain momentum over time.

Our Step-by-Step Strategy

Once we uncovered these gaps, we got to work building an AI-led system. The entire campaign ecosystem needed restructuring, and we were on it.

Revamped Performance Max with Enriched Signals

Rather than using PMax as-is, we added layers of behavioral insights, in-market interests, and purchase data. This empowered Google’s AI to locate high-value users across multiple touchpoints—from Search and Shopping to YouTube.

Ensured Creative Compliance with AI

We used AI insights to identify which elements in lingerie ads triggered disapprovals. Based on these signals, we redesigned creatives (e.g., stylized product shots without human models) to stay compliant without losing appeal..

Built an Always-On Creative Refresh Loop

We regularly replaced underperforming assets to keep engagement high and performance steady throughout the campaign lifecycle.

Boosted CTR with Smarter Ad Extensions

We implemented AI-recommended sitelinks and CTAs. This increased click-through rates, improved Ad Quality Scores, and brought acquisition costs down.
