About the Client

Rajendhra Prasath is a Chennai-based AI Marketing Coach helping entrepreneurs, business owners, and marketing professionals leverage the power of Artificial Intelligence to streamline their marketing, supercharge content creation, and build scalable digital systems.

Active across YouTube, Instagram, Facebook, X, and Threads, Rajendhra has built a growing personal brand based on delivering daily, actionable AI and marketing insights to his community. His digital products include online courses, coaching programs, and live workshops designed to upskill marketers in leveraging AI tools.

When he engaged us, his organic content was performing well in terms of engagement but wasn't converting into consistent course sales. He needed a paid advertising engine that could predictably fill his programs with qualified buyers โ€” not just random clicks.

"I was generating engagement on social media but it wasn't translating to sales. I needed a paid ads strategy that could finally connect my content audience to my paid offers at scale."

The Challenge

The personal brand and online coaching space is one of the most competitive paid advertising environments available. Rajendhra's specific challenges included:

  • Unproven ad account: No previous advertising history, meaning Meta and Google's algorithms had no data to optimize from on day one.
  • High CPL in coaching niche: The AI & marketing education space attracts high ad costs due to big-budget competitors like major EdTech platforms.
  • Fragmented audience across platforms: His audience was spread across five different platforms with varying levels of intent and purchase readiness.
  • Landing page not conversion-optimized: The existing sales page for his course had a low conversion rate, making even quality traffic unprofitable.
  • No retargeting system: Warm leads โ€” people who had watched his videos or visited his site โ€” were being lost with zero follow-up mechanism in place.

The Strategy

We designed a full-funnel paid advertising strategy across Meta (Facebook & Instagram) and Google Ads, structured around his existing content assets and audience data.

Phase 1 โ€” Foundation & Audience Research (Week 1โ€“2)

  • Installed Meta Pixel and Google Tag Manager correctly โ€” including micro-conversion events (video views, lead magnet downloads, time-on-page) to build rich audience signals from day one.
  • Analysed Rajendhra's existing Instagram and YouTube audiences to extract demographic and interest data used to build precise lookalike audiences.
  • Conducted competitor ad analysis using Meta Ad Library to identify what creatives and angles were already working in the AI marketing coaching niche.
  • Collaborated with Rajendhra to produce a free lead magnet (an AI Tools Cheat Sheet) to use as a low-friction top-of-funnel entry point into the paid ads funnel.

Phase 2 โ€” Campaign Launch & Creative Testing (Week 3โ€“6)

  • Launched a Meta Ads campaign with 8 unique ad creatives across 3 formats โ€” video testimonials, carousel breakdowns, and static quote cards โ€” to rapidly identify the top performers.
  • Ran Google Search ads targeting high-intent queries like "AI marketing course India," "how to use AI for marketing," and "AI tools for digital marketers."
  • Built a dedicated, high-converting landing page for the lead magnet โ€” achieving a 42% opt-in rate against an industry average of 25โ€“30%.
  • Set up a 5-step email nurture sequence to warm up leads from the free offer before presenting the paid course.

Phase 3 โ€” Scaling & Retargeting (Month 2โ€“3)

  • Identified the top 2 creatives from Phase 2 and scaled their budgets by 3ร— while maintaining a profitable ROAS above 3.0.
  • Deployed a retargeting campaign to segment and re-engage three warm audiences: lead magnet downloaders, course page visitors, and YouTube video viewers (via Google Ads).
  • Implemented dynamic retargeting ads on Meta showing specific course modules to users who had abandoned the checkout, recovering an estimated 18% of lost sales.
  • A/B tested landing page headlines and CTAs โ€” the winning variant improved the course sales conversion rate by 34%.

The Results

Over 3 months of continuous optimization, the campaigns delivered outstanding, measurable results:

330% ROAS
Combined return on ad spend across Meta + Google โ€” for every โ‚น1 invested, โ‚น3.30 came back in course revenue.
-48% CPL
Cost Per Lead dropped from โ‚น320 in week one to โ‚น165 by month three through continuous creative and audience optimisation.
5ร— Sales
Monthly course enrollments grew by 5ร— compared to pre-campaign organic-only period.
3.8% CTR
Average click-through rate across all Meta ad creatives โ€” more than double the industry benchmark of 1.5%.
42%
Lead magnet landing page opt-in rate โ€” significantly above the 25โ€“28% niche average.
+34%
Course sales page conversion rate improvement via A/B testing of headlines and CTAs during Phase 3.

"The results were beyond what I expected. Not only did the ROAS exceed our targets, but the quality of students joining the program improved โ€” they were already pre-sold before they even clicked 'Enroll'. The strategy was clearly thought through."

Key Takeaways

This campaign proved that personal brand paid advertising can be highly profitable when built on the right strategic foundations. The defining factors behind the 330% ROAS were:

  • Using the client's existing content and community as a free source of high-quality audience data before spending a single rupee on ads.
  • Leading with a free, high-value lead magnet rather than cold-selling the paid course โ€” dramatically reducing entry resistance.
  • Building a proper retargeting machine to ensure every warm lead received multiple, relevant touchpoints before a purchase decision.
  • Continuously testing creatives and landing page elements rather than "setting and forgetting" โ€” the optimization never stops.
