Who is ITESKUL?

ITESKUL is one of Pune's leading schools for foreign language education. They offer structured, certification-linked courses in French, German, Dutch, Japanese, and Spanish — attracting students, working professionals, children, and anyone pursuing language skills for career advancement, study abroad, or personal enrichment.

With courses priced Rs.15,000–Rs.22,000 per programme, ITESKUL operates in a considered-purchase market where students research and compare before enrolling. Brand Aura manages their complete Google Ads presence — capturing that high-intent search moment for all five languages.

02 · The Starting Point

Starting from zero

  • 📭Zero Google Ads presence — no campaigns, no conversion tracking, no account structure when Brand Aura began in 2019
  • 🎯Five entirely different learner audiences — each language course targets a distinct demographic requiring separate messaging, keywords, and bid strategies
  • 📍Single-city dependency — all enrolments coming from Pune word-of-mouth with no structured digital lead generation
  • 📊No performance benchmarks — zero historical CPC, CTR, or conversion data to build campaign strategy from
  • 🗓️Seasonal enrolment peaks — concentrated around summer and exam seasons with no year-round lead flow between periods

Google Ads: built from nothing, scaled to 5,599 form leads across five languages

Brand Aura architected ITESKUL's complete Google Ads infrastructure — from account setup and keyword architecture to Display creative, bid strategy, conversion tracking, and geographic expansion across Pune and Bangalore over seven years. All lead figures are form fill submissions only.

For Pune language courses priced Rs.15,000–Rs.22,000 per programme, generating 5,599 qualified form fill leads over seven years represents a consistent and growing lead generation engine. At a 20% lead-to-enrolment rate, this translates to approximately 1,100 course enrolments driven directly by Brand Aura's campaigns.

French and German deliver the best blended CPCs across all campaign types. Japanese Display at Rs.0.97 CPC is the standout data point in the entire account — clicks cost less than one rupee, making awareness and form lead generation at scale achievable at negligible cost.

Display is 18x cheaper per click than Search and produced the best CPL in 7 years of account history (Rs.48). Yet Display has only ever received 2.9% of total budget. The three new Display campaigns launched in March 2026 are already producing the three best active CPLs in the account.

06 · Language-Level Performance

Five languages. Five different stories.

Each language at ITESKUL serves a different learner profile — and the data tells a distinct story for each. All figures are form fill submissions only, based on real spend and lead data across all 51 campaigns.

🇯🇵 Japanese

Total Form Leads1,520
Total SpendRs.12,37,591
Est. Revenue (20% conv)Rs.60,80,000
+391% ROI — highest estimated revenue of any language. Japanese generates the most revenue (Rs.60.8L) with the best active Search CPL (Rs.333) and the lowest CPC in the entire account (Rs.0.97 Display). Japanese learners show exceptional search intent — the campaign data points to a highly motivated, high-conversion audience that is significantly underinvested relative to its potential.

🇩🇪 German

Total Form Leads1,503
Total SpendRs.10,24,714
Est. Revenue (20% conv)Rs.54,10,800
+428% ROI — highest ROI and most leads. German leads the account in both total form leads (1,503) and ROI (428%). Active across Pune and Bangalore with Search and Display formats running, German is ITESKUL's most commercially productive language across every metric. Budget for German should be the highest priority of any language in 2026.

🇫🇷 French

Total Form Leads1,295
Total SpendRs.10,47,567
Est. Revenue (20% conv)Rs.46,62,000
+345% ROI — anchor language, efficiency gap visible. French is ITESKUL's original flagship with the highest single-campaign lead count (594 from French Search). However, the active Search CPL (Rs.1,232) is 6.5x the new French Display CPL (Rs.189) — a gap that a budget rebalance toward Display can close significantly.

🇳🇱 Dutch

Total Form Leads669
Total SpendRs.7,05,552
Est. Revenue (20% conv)Rs.29,43,600
+317% ROI — Display pivot already working. Dutch Search active CPL is Rs.1,417 — the highest active CPL in the account. But the new Dutch Display campaign (Rs.71 CPL) launched in March 2026 is 20x more efficient. The demand exists; the format was wrong. Scaling Display while cutting Search budget is the clear 2026 action for Dutch.

🇪🇸 Spanish

Total Form Leads508
Total SpendRs.6,63,798
Est. Revenue (20% conv)Rs.15,24,000
+130% ROI — Search retired, Display is the answer. Spanish Search historically ran at Rs.1,621 CPL — the worst in account history. The new Spanish Display campaign (March 2026) generates form fills at Rs.65 CPL — the best active CPL in the entire account. Spanish should never return to Search. Display is the format, and scaling it aggressively in 2026 is the priority.

08 · What Brand Aura Built

The strategy behind the numbers

Brand Aura didn't just run ads for ITESKUL — we built the complete Google Ads infrastructure, campaign architecture, and language-market intelligence system from zero across seven years and 51 campaigns.

01

Full Account Architecture from Zero

When Brand Aura started in 2019, there were no Google Ads campaigns for ITESKUL. We built everything: account structure, keyword research across five languages, ad copy frameworks, form fill conversion tracking, and bid strategies calibrated to the language education market in Pune.

  • 5 language-specific keyword sets built from ground up
  • Form fill conversion tracking set up across all campaigns
  • Separate campaign structures per language for clean data
02

Language-by-Language Market Discovery

Seven years of campaign data across five languages revealed market behaviours impossible to see without sustained management. Japanese has the best active Search CPL (Rs.333) and lowest Display CPC (Rs.0.97). German leads in total form leads. French has the largest volume. Each required a completely different strategic approach.

  • German: 1,503 form leads — most of any language, best ROI
  • Japanese: Rs.0.97 Display CPC — 20x cheaper than Search
  • French: 594 active form leads — highest single-campaign count
03

The Display Efficiency Discovery

The best CPL in 7 years of account history — Rs.48 — came from a Display campaign, not Search. Display campaigns average Rs.1.08 CPC vs Rs.19.11 for Search — an 18x difference. The three Display campaigns launched in March 2026 are already producing the three best active CPLs in the account: Rs.65, Rs.71, and Rs.189.

  • Multi-language Display: Rs.48 CPL — 7-year all-time record
  • Spanish Display: Rs.65 CPL vs Search: Rs.1,621 (25x cheaper)
  • Dutch Display: Rs.71 CPL vs Search: Rs.1,417 (20x cheaper)
04

Geographic Expansion — Bangalore Proven

Brand Aura identified Bangalore as a viable second market for German and Japanese — both with strong demand from IT professionals and students. Both Bangalore campaigns are active and validated, opening a growth vector independent of Pune market conditions.

  • German Bangalore: 156 active form leads at Rs.477 CPL
  • Japanese Bangalore: 148 active form leads at Rs.375 CPL
  • City-expansion model proven — Mumbai next
05

Campaign Consolidation & Hygiene

From 51 historical campaigns, Brand Aura consolidated to 12 high-performing active campaigns. Underperforming campaigns — Spanish Search (Rs.1,621 CPL), Dutch Search (Rs.1,417 CPL) — were identified, paused, and replaced with Display alternatives at 20-25x better efficiency.

  • 51 campaigns built and tested → 12 optimised, active today
  • High-CPL Search campaigns retired, replaced with Display
  • Each active campaign has a clear language, geo, and format rationale
06

Full-History Audit & 2026 Roadmap

Brand Aura produced the first-ever full Google Ads historical audit for ITESKUL — mapping all 51 campaigns, 7 years of form fill data, every language CPL, and the Search vs Display efficiency gap. The roadmap targets Rs.2+ crore in annual course revenue with the same or lower ad spend.

  • 51 campaigns analysed — form fills only basis throughout
  • Display vs Search gap identified and quantified per language
  • Budget reallocation plan built to maximise ROI without increasing spend
Brand Aura didn't just bring us more enquiries — they brought the right enquiries, consistently, across every language we teach. Seven years later, Google Ads is the backbone of how students find ITESKUL.
