4 Campaigns · Product + Geo Segmented

The catalogue spans hardware, cement, paints, roofing, plumbing and structural steel — too broad to advertise as one thing. So instead of one generic campaign, the account became four narrow, trackable bets.

A Construction Materials Retailer

A construction-materials retailer operating across Kerala, positioned around a wide multi-category catalogue rather than a single product line. Cladding and fencing ran as its two core product-led campaigns, alongside a small local-market test.

What Trelis Focused On

Ran cladding and fencing as two separate lead-generation campaigns instead of one blended "construction materials" campaign.

Tested a named local market as its own standalone geography to see whether demand held up outside the core region before committing more spend.

Paired a lead form with a WhatsApp option in that local-market test, giving lower-intent prospects a lighter way to start a conversation.

Tracked cost per result at the individual campaign level throughout, so budget could shift toward whichever product line was actually converting.

Kept this account focused on the retailer’s own core catalogue — a related but separately-run sister brand’s product line is reported on its own.

Used campaign-level reporting, not account averages, as the basis for every optimisation decision.

Selected Campaign Proof Points

Four campaigns, four cost curves

Splitting a broad catalogue into narrow campaigns is the only way to see that one product line is meaningfully more efficient than another at similar spend levels.

Cladding Leads
405 leads at ₹40.06 — the most efficient line in the account, and its largest campaign by volume.
Fencing Leads
238 leads at ₹67.80 — a separate acquisition path for a distinct product category.
Test-Market Leads
79 leads at ₹90.25 — a smaller local market tested on its own budget.
Test-Market WhatsApp
21 conversations at ₹65.41 — a lighter-touch option alongside the lead form in that same market.
Why This Matters

Splitting a broad catalogue into narrow campaigns costs more setup effort up front, but it’s the only way to see that cladding is meaningfully more efficient than fencing — a signal that’s invisible inside one blended account number.

How We Approached The Challenge

Five operating principles behind the numbers

Split the catalogue, not the budget

Cladding and fencing each got a dedicated campaign so cost per result could be compared honestly.

Test new geography on its own line

The local market ran as a standalone campaign rather than folding into the core Kerala budget.

Offer more than one conversion path

A lead form captured structured enquiries; WhatsApp gave a lighter option to less-ready prospects in the test market.

Judge every campaign on its own number

No campaign was compared against a blended account average — each stood on its own cost per result.

Keep the account to this brand’s own catalogue

A sister brand’s specialised product line is reported as its own separate case, not blended in here.

Let the data pick the next investment

Cladding’s efficiency over fencing is a budget-reallocation signal, not a one-off observation.

Where This Can Compound Next

Shift incremental budget toward cladding — it’s outperforming fencing on cost per lead at similar spend.

Expand the test market to a full campaign if early efficiency holds.

Add a third product-specific line for another high-catalogue-share category.

Test WhatsApp as a parallel option on the core Kerala campaigns, not just the test market.

"A broad catalogue is not one campaign waiting to happen — it’s several. The account only got useful once each product and market got its own number to be judged by."
