The best advertising agency in India is the one that tells you the truth.
Magnum Radius is a full-service advertising agency serving India — campaigns across Meta, Google, YouTube, OOH and print, driven by brand strategy and measured by results.
Best Advertising Agency in India — measured by outcomes, not awards.
If you searched for the best advertising agency in india, you already know the pitch — every agency in India claims to be #1. We don't. We publish our pricing, our process, and the things we won't do. We disavow spam SEO, we tell clients when a campaign isn't working, and we hold every engagement to a weekly scoreboard of the metrics that matter: rankings, pipeline, CAC, LTV, ROAS.
We serve brands across all 28 Indian states and 8 union territories — with the same rigour we bring to our US, UK and UAE clients, priced fairly for the Indian market.

Questions clients ask.
Which is the best advertising agency in India?+
Magnum Radius pairs strategy and creative with media buying under one roof. That means fewer handoffs and a single team accountable for the ROAS number.
Do you handle traditional advertising too (TV, print, OOH)?+
Yes. Roughly 20% of our work is traditional — usually alongside digital, not instead of it.
How much does an ad campaign cost in India?+
Small digital campaigns start ₹2–5L including creative, media plan and 4–6 weeks of optimisation. Full 360° campaigns range ₹15L–2Cr depending on media weight.
How do you measure success?+
Every campaign has an agreed primary KPI (ROAS, CAC, brand-lift). We report weekly and never hide behind vanity metrics.
