GOZOCAB TECHNOLOGIES
gozocabs.com · Local Transport, Kolkata
3x

Gozocab, a Kolkata-based cab aggregator, was spending heavily on broad, untargeted campaigns with a high CPL and no scalable audience strategy. The absence of retargeting meant most traffic was wasted.

Built a complete audience architecture from scratch — custom audiences from website visitors, lookalike audiences from existing customers, and a multi-stage retargeting funnel. Geo-targeted Google Ads covered high-value Kolkata pickup zones. Budget was reallocated weekly based on KPI dashboards.

UK Subsidiary · Multi-Industry
40%+

Managing multi-industry UK client accounts from Kolkata across IST/GMT timezones. Low CTR across campaigns due to generic audience targeting and weak ad creative strategy.

Rebuilt audience segmentation from the ground up for each industry vertical. Developed customer journey mapping frameworks that reduced funnel drop-off. Established a cross-timezone communication workflow with daily updates and weekly video calls.

GOUTAM SHASTRIC
goutamshastric.com · Professional Services
45%

A professional services brand with minimal organic visibility and a Google Ads account generating poor ROAS. No coherent full-funnel strategy connecting paid and organic channels.

Executed a complete digital overhaul — technical SEO audit and fixes, targeted keyword strategy aligned with commercial intent, and content optimisation across all pages. Simultaneously restructured Google Ads campaigns and Meta Ads for consistent pipeline growth, achieving 2.8x average ROAS.

M+

123Greetings.com was one of the earliest and largest online greeting card platforms of the internet era — operating at a time when digital marketing was being invented in real time. Managing internet marketing for a US audience from 1998 to 2004 was pioneering work with no playbook to follow.

Developed and executed early SEM strategies, email marketing campaigns, and web analytics frameworks that grew the platform to millions of monthly visitors. These performance-based user acquisition systems became the foundation of Arun's entire career methodology.
