Each case study shows the exact issue found, how Adnexusone surfaced it, and the before/after performance impact.
Situation
Running 22 active creatives across 6 ad sets. Frequency hit 6.3× on their primary retargeting audience. CTR had dropped 38% over 3 weeks but the team attributed it to seasonality.
What Adnexusone found
Adnexusone flagged frequency saturation on the retargeting ad set and identified 4 specific creatives with CTR below 0.8%. The AI brief recommended a UGC-led angle targeting review objections rather than benefits.
Before
After
Situation
The brand had a blended Shopping ROAS of 4.1× and was happy. When Adnexusone segmented branded vs. non-branded, the picture changed entirely — non-brand ROAS was 1.4×.
What Adnexusone found
Adnexusone detected that brand-name search terms were grouped in the same campaign as generic product terms, masking the true non-brand performance. Separating campaigns exposed the waste.
Before
After
Situation
Six auto campaigns running for 14+ months. ACOS at 44%. The team had never reviewed search term reports. ₹2.3L/month was running through terms with zero sales history.
What Adnexusone found
Adnexusone identified 127 unique search terms with 30+ days of spend and zero conversions. It also flagged 3 zero-sale ASINs receiving ₹40K/month in sponsored spend.
Before
After
Situation
Managing 18 client accounts. With one weekly audit cycle, budget exhaustion, pixel failures, and ROAS drops were often discovered 5–7 days after they began — sometimes after client escalation.
What Adnexusone found
Adnexusone ran continuous diagnostics and surfaced 3 critical issues in the first week: a pixel failure on a ₹80K/month account, a budget exhaustion pattern on a peak-season client, and keyword cannibalization inflating CPCs by 22%.
