₹62 lakh in revenue from about ₹2.04 lakh of ads, for a specialised course in a little-known category

A specialised course is hard to sell when few people know the subject exists. That was the position of a niche edtech brand selling in Tamil Nadu and Kerala. It could not simply wait for people to search for it, because hardly anyone was searching.

We paired high-reach awareness creatives with a separate local lead funnel in each state. In total, roughly ₹2.04 lakh of ads in the two states produced 3,965 leads and ₹62 lakh in revenue. In Tamil Nadu alone, the return came to about 44.7 times the ad spend.

At a glance

The client

The client is an edtech brand in South India built around one offer: a specialised course in a category that few people had heard of. That single fact shaped everything about how it needed to advertise.

Think about how most people buy a course. They notice a gap in their skills or their career. They search, compare a handful of options and enrol. The provider's job is to show up during that comparison and make the strongest case.

A niche course does not follow that path. The buyer has to discover the subject before they can want the course. Many of the people who would gain the most from it never think to look for it, because they do not know it is an option. So the journey has an extra first step: someone has to explain why the subject matters at all.

The brand also sold in two states. Tamil Nadu and Kerala sit side by side on the map, but each has its own language, its own audience and its own habits. For a marketer, that makes them two markets, not one.

The challenge

Most course advertising is built to catch demand that already exists. The ads ask for a sign-up from people who are already in the market. That works well when the market is large. In a niche category, the pool of people ready to enrol is small. Ads that do nothing but request a sign-up quickly exhaust the few people willing to give one.

The brand needed to do two jobs at once. It had to introduce the subject to people for whom it had never been on the radar, and then convert the curious ones into enquiries. Doing only the first would build familiarity without sales. Doing only the second would keep asking strangers to act on something they did not yet understand.

On top of that, both jobs had to work in two states. A single campaign written once and copied across the border would treat two different audiences as if they were the same.

What we did

Making the subject familiar, not just the name

In Tamil Nadu and Kerala alike, we ran wide-reaching creatives built for awareness and for the brand. Their purpose was to make the subject itself familiar, so that by the time someone was asked to enquire, the course already made sense to them.

This matters because people rarely enquire about something they cannot picture. In a new category, awareness work is not decoration. It is the part of the sale that answers the first question every stranger has: what is this, and why would I need it? The same idea of building recognition first sits behind our work for a college with specialised programmes in South India.

A local lead funnel in each state

Running next to that awareness activity, each state got its own local lead funnel, designed to convert. We did not build one funnel and copy it into the other state.

A local funnel can speak directly to the people it is meant for. What persuades one audience may fall flat with the other, and keeping the funnels separate let each one be shaped around its own market.

Awareness and leads working as a pair

In both states, the awareness creatives and the lead funnels ran together. At no point did the brand depend on lead ads by themselves to sell an unfamiliar subject. The awareness side created the interest, and the lead side gave that interest somewhere to go.

The results

Tamil Nadu was the standout. Ads costing ₹84,978 there led to ₹38 lakh in revenue, a return of about 44.7 times the spend. Kerala added ₹24 lakh in revenue from ₹1,19,000 of ads. Taken together, about ₹2.04 lakh of advertising led to 3,965 leads and ₹62 lakh in revenue.

What makes these numbers worth studying is where they came from. They were not earned in a crowded category full of ready buyers. They came from a course that few people knew about when the work began, which means the campaigns had to create much of their own demand.

Why it worked

Awareness was treated as part of the sale

In a new category, people need to understand the subject before they will ask about the course. Lead ads on their own ask for action too early. The brand-building creatives did the explaining, which gave the lead funnels warmer people to work with.

Each state had its own funnel

Separate, localised funnels respected the fact that Tamil Nadu and Kerala are different audiences. Each funnel could be shaped around its own audience, instead of forcing one message on both.

Lead volume came with real value

Volume alone can mislead. A long list of names means little if nobody buys. Here, Tamil Nadu alone produced 2,222 leads and ₹38 lakh in revenue, which shows the leads were genuine prospects, not just entries on a spreadsheet.

No one signs up for a course they have never heard of.

How to apply this to your business

• Ask honestly whether people already search for what you sell. If they do not, plan for awareness as part of your marketing from the first day, not as an extra.
• Give your awareness ads one clear job: explain the problem your product solves, in words a stranger would understand.
• Run lead ads alongside awareness, not instead of it, so new interest always has a clear next step.
• If you sell in more than one region or language, build a separate funnel for each one rather than copying a single campaign everywhere.
• Judge each region on revenue as well as lead count, and compare them side by side.
• Track which leads go on to pay, so you know whether volume is turning into value. Our career training institute case shows why admissions, not lead counts, are the number to watch.

Questions business owners ask

How do you advertise a course people have never heard of?

Start by explaining the subject, not by asking for a sign-up. For this brand, we paired high-reach awareness creatives with lead funnels, so people met the category first and were asked to enquire once it made sense to them.

Should an edtech brand run separate campaigns for each state?

When the states have different languages and audiences, it usually helps. We built a localised funnel for Tamil Nadu and another for Kerala instead of one copied funnel. Ad spend in Tamil Nadu came back about 44.7 times over, and Kerala brought in ₹24 lakh in revenue.

Is brand awareness worth paying for when what you need is leads?

In a niche category, often yes, because awareness creates the people your lead ads will later convert. Here, awareness and lead funnels ran as a pair, and together they produced 3,965 leads and ₹62 lakh in revenue from about ₹2.04 lakh of ads.

What is a good cost per lead for an online course?

It depends on the course price and how many leads go on to enrol, so revenue per rupee spent is a better guide than cost per lead alone. In Tamil Nadu, leads cost about ₹38.24 each, and ₹84,978 of ads led to ₹38 lakh in revenue.
