One domain, one funnel, no handoff
There is a standard shape to B2B demand gen: the marketing site lives on one domain, the campaign landing pages live on a marketing automation subdomain, and prospects cross between them at the exact moment they are most likely to convert. It is an architecture chosen for the marketing team's convenience, and the visitor pays for it.
Challenge
The conversion path crossed a domain boundary. Sending prospects from the marketing site to a separate landing page system split the funnel in two: tracking continuity broke at the handoff, the visual experience changed underneath the visitor, and the pages that earned the most intent lived off the domain accruing the SEO value.
Solution
Rather than run a separate demand gen subdomain, I embedded custom Marketo forms directly into native Webflow pages and component symbols, so the form was part of the page instead of a destination the visitor was sent to. Marketo email templates were rebuilt to match the brand system, so what arrived in the inbox after a submission looked like the page that produced it. Marketing kept its native Marketo data; the visitor never left the site.
Outcome
The funnel stayed on one domain end to end. Tracking held together across the whole path instead of resetting at a handoff, the pages carrying the most intent kept contributing to the domain's SEO position, and marketing lost nothing on the data side because the forms were Marketo forms.
The build
At Carrot we went the other way. Instead of standing up a separate landing page system, I embedded custom Marketo forms directly into the native Webflow site — into pages and into reusable component symbols, so a form could be dropped into any layout and behave the same way. From the visitor's side there is no transition: the form is part of the page they were already reading, in the same type, on the same domain, at the same speed.
Keeping the funnel on one domain fixes three problems at once, and they are usually treated as three separate teams' problems. Tracking stops resetting at a boundary, so the path from first touch to submission is one continuous story rather than two fragments someone has to stitch together. The visual experience never breaks, so the trust built by the page carries into the moment of conversion. And the pages that attract the most intent keep contributing their authority to the domain instead of donating it to a subdomain.
None of that would have been acceptable if it cost the marketing team their data. The forms are real Marketo forms, not a custom collector that syncs later, so lead records, programs, and campaign attribution behave exactly as marketing ops expects. The integration was engineered so the marketing automation platform still owns the record — the only thing that changed is where the form is rendered.
I extended the same logic downstream by rebuilding the Marketo email templates against the brand system. A submission that produces a confirmation email in a different visual language undoes some of what the page just built. Matching the templates to the site made the whole sequence — page, form, inbox — read as one experience rather than as three systems introducing themselves in turn.
The general principle: the seams between marketing systems are where conversion, measurement, and trust leak out. Most of the engineering value on a marketing site is in removing seams the visitor should never have been asked to cross.
