Funnel build from ad click to checkout, with the data spine

What decides whether this funnel works is not the page. It is whether a deal closed 40 days after the click can be traced to the click that caused it and posted back to the ad platform. A freight operator with a 30 to 60 day cycle who reports only form submissions is bidding on the wrong signal for the entire window, and no landing page fixes that. We build the pages and the return path as one job, or we pass on the work. The spine of the build: Click identifiers, gclid, gbraid, wbraid and fbclid, are captured server side, written to a first-party cookie and stamped onto the lead record in HubSpot or Pipedrive at creation. Browser events are mirrored server side: GA4 through a container on a first-party subdomain, Meta through the Conversions API with event_id deduplication against the pixel, Google with enhanced conversions for leads on a hashed email. When the deal stage changes, the stored identifier goes back as an offline conversion carrying a value, not a count. The form is part of the pricing conversation: For freight and for trades work the questions that matter are lane or Eircode, weight or pallet count, incoterm, hazardous goods and collection window. Five questions your operations team can price beat twelve generic ones: fewer submissions arrive, and the sales team stops rejecting half of what does. We write the form with whoever quotes the work, not from the marketing brief. Through to checkout: Where the funnel ends in a transaction, wallet buttons sit above the fold on mobile, address entry uses Eircode lookup for Irish delivery, and payment runs through Stripe Payment Element or Shopify checkout extensibility. Purchase events fire server side, so an ad blocker moves your reported revenue by a rounding error rather than by a third. Consent: Consent Mode v2 has been required in the EEA for Google audience and measurement features since March 2024. Consent state is carried honestly through the server container. We will not set a default granted state for European traffic to make a dashboard look healthier, and we will tell you plainly what modelling gap that leaves in the reporting. Not included: Media buying, creative production and audience strategy. CRM licences and the running cost of a server container. Sales process design and training. ERP or transport management system integration beyond a documented API endpoint. Legal review of your consent notice, which your own counsel should sign off. Who this is not for: Companies whose sales team will not mark deals closed or lost inside the reporting window. Without that, offline conversions never post, and the funnel degrades into the guesswork you already have with a better page on top of it. Also not for a business whose only call to action is a demo booking answered in three working days; fix the response time first, then talk to us. What we refuse: We refuse to fire purchase or qualified-lead events from the browser alone. We refuse to build a lead capture whose fields exist to feed a scoring model rather than to price the job. And we do not guarantee a cost per acquisition, because that number belongs to your offer, your margin and your media buyer, and we control none of the three.
