The single most underutilised performance lever in Indian digital advertising is vernacular creative strategy. We have audited hundreds of Indian Meta accounts, and a consistent finding is that brands running English-only creatives nationally are significantly underperforming in every non-metro market — not because the product is wrong, not because the targeting is off, but because the language and cultural framing of the ad is creating friction for audiences who primarily think and communicate in their regional language.
India's linguistic reality is striking. According to the 2011 Census of India, only 10.4% of Indians report Hindi as their mother tongue and use it as a primary language. When you include all scheduled and non-scheduled languages, the country has 22 constitutionally recognised languages and hundreds of dialects. Meta's own data on Indian users shows that a large majority of Facebook and Instagram users in South India, East India, and parts of Western India prefer content in their regional language when given the choice.
This guide presents the performance benchmarks we have collected across our managed accounts, broken down by language, region, and category. The data covers Q3 2025 through Q1 2026 — approximately 18 months of live campaign data across 200+ Indian brands.
Methodology and Benchmark Definitions
All benchmarks below are drawn from A/B tests conducted within the same campaign — same audience, same budget, same placement settings — comparing a vernacular creative against a directly equivalent English creative. This controls for all variables except language, giving us clean language-effect measurements.
Metrics reported:
- CTR lift: Click-through rate of vernacular creative divided by CTR of English creative (e.g., 2.1x means 110% higher CTR)
- CPL differential: Cost per lead for vernacular vs English (negative = vernacular is cheaper)
- ROAS lift: Revenue-on-ad-spend improvement for vernacular campaigns vs English-only campaigns in the same geography
| Language | Primary Region | CTR vs English | CPL vs English | ROAS lift |
|---|---|---|---|---|
| Hindi | UP, Bihar, MP, Rajasthan | +2.3x tier-2/3 +1.4x metro | −38% tier-2/3 | +41% |
| Tamil | Tamil Nadu | +2.1x tier-2/3 +1.6x Chennai | −44% tier-2/3 | +38% |
| Telugu | AP, Telangana | +2.0x tier-2/3 +1.5x Hyderabad | −40% | +35% |
| Bengali | West Bengal | +1.8x tier-2/3 +1.3x Kolkata | −35% | +31% |
| Marathi | Maharashtra (non-Mumbai) | +2.0x tier-2/3 +1.2x Mumbai | −37% | +36% |
| Gujarati | Gujarat | +1.9x tier-2/3 +1.4x Ahmedabad | −33% | +29% |
| Kannada | Karnataka (non-Bengaluru) | +1.8x tier-2/3 +1.2x Bengaluru | −32% | +27% |
| Malayalam | Kerala | +1.7x overall | −29% | +24% |
| Punjabi | Punjab, Haryana | +1.6x tier-2/3 | −28% | +22% |
Why the Metro vs. Tier-2/3 Gap Is So Large
You will notice in the benchmark table that vernacular lift is consistently larger in tier-2 and tier-3 cities than in metros. Chennai sees 1.6x CTR lift for Tamil ads vs English; non-Chennai Tamil Nadu sees 2.1x. This pattern repeats across every language.
The reason is English proficiency and media consumption patterns. Metro audiences — Bengaluru, Mumbai, Delhi NCR, Chennai, Hyderabad — contain large populations of English-educated professionals who comfortably consume English advertising. Their response to well-crafted English ads is reasonably strong.
Tier-2 and tier-3 audiences — Coimbatore, Madurai, Nagpur, Surat, Lucknow, Patna — have much lower English consumption as part of their daily media diet. When they encounter an English ad, there is a processing friction: the language is not the one they think in. When they encounter a well-crafted ad in their mother tongue, that friction disappears. The message lands directly, emotionally, without translation overhead.
This matters enormously for Indian D2C brands because tier-2 and tier-3 cities represent the fastest-growing consumer market in India. According to Dentsu India's Digital Report, digital users in tier-2 and tier-3 cities now account for over 55% of India's total online consumer base. Running English-only ads to this audience is leaving the majority of the market underserved.
Category-Level Vernacular Performance
The vernacular advantage is not uniform across categories. Here is what we observe by product type:
Fashion and Ethnic Wear: Highest Vernacular Impact
Fashion advertising in India has particularly strong vernacular performance because the emotional trigger — cultural identity, celebration, aspiration — is deeply language-linked. A saree ad with the headline "इस त्योहार पर पहनें कुछ खास" outperforms "Wear something special this festival" not just on CTR but on conversion rate and ROAS, because the cultural framing is more resonant. Fashion is the category where we consistently see the largest vernacular CTR lifts — often 2.3-2.8x in tier-2 North India for ethnic wear.
Food and FMCG: Strong in Regional Markets
Food advertising in regional languages taps into deeply regional taste preferences and cooking culture. A cooking oil ad showing dal tadka with Hindi copy in UP, vs sambar preparation with Tamil copy in Tamil Nadu, will dramatically outperform a generic English ad showing a generic dish. Regional food brands already understand this instinctively; national FMCG brands are often slower to adapt.
Electronics: Moderate Vernacular Lift
Electronics advertising shows a more moderate vernacular effect — typically 1.4-1.7x CTR lift vs English in tier-2 cities. This is because electronics purchase decisions are more feature-driven and specification-focused, and English technical terminology is widely understood even by non-English speakers for product categories like smartphones and TVs. However, the trust signal of seeing a brand communicate in your language still has a meaningful positive impact on conversion rates.
Financial Services: Highest Trust Impact
Financial products — insurance, loans, investment apps — show some of the highest vernacular conversion rate improvements we measure. The relationship between language and trust is especially strong for financial decisions. A loan offer explained in fluent Marathi to a Pune audience converts significantly better than the same offer in English because financial trust is built on clear, unambiguous communication in the language the consumer thinks in.
Why Translation Is Not Enough
The most common vernacular mistake we see is treating language adaptation as translation. Taking an English headline and running it through Google Translate, then using that as your Hindi or Tamil headline, does not deliver vernacular performance gains. It often performs worse than the English original because the translation is stilted, loses the cultural idiom, and signals that the brand has not genuinely invested in the audience.
Genuine vernacular creative requires:
- Native copywriting: Headlines written by native speakers in the tone and idiom natural to that language, not translated from English
- Cultural references: Festival greetings, regional food, local customs — contextualised for the specific audience
- Script accuracy: Correct script rendering (Devanagari for Hindi, Tamil script for Tamil, Bengali script for Bengali) — not romanised transliterations
- Tone calibration: Different languages carry different default tonal registers in advertising. Tamil advertising culture tends toward direct benefit communication; Bengali advertising culture leans more literary and aspirational; Gujarati advertising is often more value and offer-focused
AdsSarthi's vernacular creative generator handles all of these dimensions across 13 Indian languages — Hindi, Tamil, Telugu, Kannada, Marathi, Bengali, Gujarati, Malayalam, Odia, Punjabi, Assamese, Urdu, and English. You provide the product brief and offer in English; the system generates culturally appropriate copy in each target language, which you review before publishing.

Practical Guide: Which Languages to Prioritise First
If you are new to vernacular advertising and cannot immediately deploy all 13 languages, here is our recommended prioritisation framework based on ROI:
- Hindi first (if you have any North India targeting): Largest reach, highest absolute impact, covers UP, Bihar, MP, Rajasthan, Delhi NCR tier-2
- Tamil second (if you target Tamil Nadu): Highest percentage CTR lift after Hindi, strong e-commerce adoption in Tamil Nadu
- Marathi third (for Maharashtra outside Mumbai): High population, strong D2C growth, significant English-comfort gap in tier-2 Maharashtra
- Telugu fourth (for AP/Telangana): Large population, rapidly growing digital ad adoption
- Bengali fifth (for West Bengal): Significant market, and Bengali identity is particularly strongly tied to language
This sequence covers approximately 65-70% of India's population with five language variants. The remaining eight languages extend coverage to the remaining states and specific high-value audiences like Gujarati (Navratri/Diwali), Malayalam (Kerala), and Kannada (Karnataka).
