Performance Marketing Case Studies & Client Results
First-Party Performance Proof & Verified Case Studies
Performance Marketing Case Studies & Audited Growth Results
Transparent, data-backed breakdowns of paid acquisition campaigns engineered by Subhranil Naskar. Real budgets, audited attribution windows, and verified business outcomes across B2B SaaS, Global EdTech, E-Commerce, and Mobile Apps.
Audited Attribution & Reporting Methodology
Every metric presented below is reconciled directly from primary ad platforms (Google Ads, Meta Ads Manager, Apple Search Ads), server-side conversion telemetry (GA4, Meta CAPI, offline CRM imports), and client e-commerce dashboards (Shopify, Stripe, Zoho CRM). We do not blend ad-attributed revenue with total organic store turnover without explicitly distinguishing the two. Peaks are clearly marked as weekly or cohort maximums alongside blended period averages.
