228,000 Leads at ₹26.27 CPL: How I Beat India’s EdTech Industry Benchmark With Precision Google Ads
| Industry / Client | EdTech — Chegg India Pvt. Ltd. (India’s leading online tutoring & exam-prep platform) |
| Role | Team Lead — Digital Acquisition |
| Timeline | ₹60 Lakhs/year (₹5 Lakhs / month) across Search, Display & Remarketing |
| Budget Managed | ₹60 Lakhs/year (₹5 Lakhs/month) across Search, and Display |
PROBLEM STATEMENT
Chegg India was spending heavily on Google Ads but bleeding budget. Cost-per-lead (CPL) had crept up to ₹52, while the industry benchmark sat between ₹150–200. On the surface, performance looked acceptable — but internally, Quality Scores were mediocre (5–6/10), campaigns were broad-matched and poorly segmented, and a significant portion of spend was being wasted on irrelevant searches. The business needed a step-change: not just marginal improvements, but a structural overhaul that could halve CPL, double impression share on target keywords, and directly contribute to lead-volume growth targets.
CLIENT CHALLENGE & CONSTRAINTS
- CPL was ₹52 — already below the industry average, but leadership wanted a further 40–50% reduction without slashing volume.
- Campaign architecture was flat: broad-themed ad groups mixed high-intent and low-intent queries, diluting Quality Scores.
- No structured remarketing in place — visitors who dropped off the sign-up funnel were not being recaptured.
- Attribution was last-click only, causing Display and Remarketing channels to appear unprofitable and receive under-investment.
- Manual reporting consumed 6+ hours/week, limiting time for strategic optimisation.
APPROACH & EXECUTION
Phase 1 — Campaign Restructuring (Months 1–3)
- Rebuilt the entire Google Ads account into Single Keyword Ad Groups (SKAGs) — tightly themed sets of 1–3 keywords per ad group, matching ad copy exactly to search intent.
- Eliminated broad-match waste through aggressive negative keyword pruning, removing 300+ irrelevant search terms and reducing wasted spend by ~22%.
- Lifted Google Quality Score from 5–6/10 to 7–9/10, which directly lowered CPCs by 18–22% on high-volume terms.
Phase 2 — A/B Testing & CTR Optimisation (Months 3–6)
- Ran systematic A/B tests on ad copy — testing urgency triggers, social proof (e.g. ‘30L+ students enrolled’), feature highlights, and price anchoring.
- Lifted Google Search CTR from ~3.1% to ~5.2% (vs. industry average of 2.5–3.5%), compounding the Quality Score gains.
- Built dedicated, high-converting landing pages per ad group segment (exam-prep, homework help, textbook rental) — tailoring messaging to search intent.
Phase 3 — Remarketing Framework (Months 6–9)
- Engineered a 3-segment remarketing architecture: (1) Content visitors, (2) Sign-up drop-offs, and (3) Quiz completers — each with distinct bids, creatives, and urgency messaging.
- Remarketing contributed ~20% of monthly leads at a CPL 30% lower than cold traffic, adding significant incremental volume at minimal marginal cost.
Phase 4 — Attribution Modelling & Budget Reallocation (Months 9–12)
- Shifted from last-click to data-driven attribution modelling. Analysis revealed Display and Remarketing contributed 28% more pipeline value than last-click reported.
- Reallocated budget toward high-assist channels, increasing ROAS efficiency across the account to an estimated 3.8–4.2x.
- Achieved 68%+ impression share on primary target keywords — dominating the competitive EdTech search space.

| Cost-per-Lead (CPL) | ₹52 | ₹26.27 | 50% reduction YoY |
| CPL vs. Industry Avg | 74% below (₹52) | ₹26.27 | 83% below ₹150–200 avg |
| Google Quality Score | 5–6 / 10 | 7–9 / 10 | +2–3 point uplift |

RESULTS & BUSINESS IMPACT
- 228,000+ leads generated at a blended CPL of ₹26.27 — on a ₹60L annual budget, delivering an estimated ROAS of 3.8–4.2x.
- Revenue attribution: 228K leads × ~5% paid-to-subscriber conversion × ₹2,000 avg LTV ≈ ₹2.28 Crore in attributed revenue on ₹60L ad spend.
- Remarketing framework alone contributed ~20% of monthly leads at 30% lower CPL vs. cold traffic — high-efficiency incremental volume.
- Multi-channel attribution revealed 28% more pipeline value from Display and Remarketing, directly enabling smarter budget reallocation.
- Saved ~₹13L+ in wasted ad spend annually through negative keyword management and match-type optimisation.
KEY LEARNINGS & TAKEAWAYS
- SKAG architecture is not just a best practice — it is a Quality Score multiplier. Tighter ad groups directly reduce CPCs and improve ad rank without increasing bids.
- A/B testing ad copy is continuous, not a one-time task. The biggest CTR gains came from iterating 20+ variants over 12 months, not from a single winning test.
- Remarketing is the most overlooked lever in EdTech paid media. A structured 3-segment funnel can contribute 20% of leads at 30% lower CPL — it is essentially ‘free efficiency’.
- Last-click attribution lies. Switching to data-driven attribution fundamentally changed how budget was allocated and improved overall account ROAS by ~15%.
- Quality Score improvement is a compounding flywheel: higher QS → lower CPC → more budget efficiency → more impressions → more clicks → more conversions.
| “Rajeev’s systematic approach to restructuring our Google Ads campaigns was transformational. The combination of SKAG architecture, Quality Score focus, and a proper remarketing funnel drove results we hadn’t seen in five years of running paid campaigns. The CPL reduction paid for his entire year’s remuneration in the first quarter alone.” — Senior Marketing Director, Chegg India |
