Most real estate loss happens after the click. Build one mobile first landing page per campaign with the project name matching the ad, the price and payment plan visible without scrolling, a unit mix table, proximity in minutes, a trust block and no site navigation. Keep the form to four fields including a country selector and one qualifying question. Treat WhatsApp as a first class path with pre filled messages routed by campaign, but count it as a secondary conversion until the CRM records a reply. Speed to lead decides more than the ad: an automated price list within 60 seconds and a human attempt within five minutes. Capture gclid in the CRM so closed deals can be tied back to keywords.
