Each offer gets its own campaign: a free aircon check for HDB flats, a trial clean for offices, a rental review for condo landlords.
Audiences come in layers: a radius around estates and business districts, past visitors to your area pages, and customer lists you have consent to use. Existing customers are excluded.
Each offer gets three or four versions of the ad, swapped when people start seeing the same one too often, which happens quickly on a compact island. Small decisions go to click-to-WhatsApp or an instant form, and larger ones go to a landing page.
Someone must reply within the hour, or the lead cools.
