Marketing Sites & Conversion

We build the ones that pay for themselves.

Most agencies deliver design. We deliver pipeline. Critonyx builds marketing sites for founders and operators who need the site to do real commercial work — capture qualified leads, qualify them automatically, and feed the sales team people who are already ready to buy.

You hired a designer. The site looks beautiful. The launch was celebrated on LinkedIn. Six months later, you check the analytics — and the bounce rate is 80%, the conversion rate is rounding to zero, and the sales team is still complaining that they don't have enough leads.

Nobody got fired. The site looks great. But it isn't producing anything.

That's the silent failure mode of most marketing sites — they're built to satisfy the people who made them, not the people who were supposed to use them. They get critiqued on aesthetics in design reviews and never on outcomes in board meetings.

Our commitments

01

"We design backwards from the lead."

Most sites are designed forwards — hero, about, services, contact. We design backwards — starting from what a qualified lead in your CRM looks like, then engineering every page, headline, and form field to produce more of that.

02

"We treat copy as the infrastructure."

The single biggest reason marketing sites underperform is bad writing. Strategy and writing happen together, before the design starts — because no amount of beautiful UI can rescue a sentence that says nothing.

03

"We instrument the site to learn."

We ship with conversion tracking, scroll depth, heatmapping, and event tagging built in — and we tune the site post-launch based on what the data shows. Most agencies hand over and walk away. We hand over and stay.

Founder-led brand sites that close enterprise deals.

When the buyer is sophisticated, the cycle is long, and the site is the silent salesperson that runs while you sleep.

High-intent landing pages for paid campaigns.

When the cost of a click is rising and your conversion rate is the only thing that decides whether the campaign returns.

Multi-page conversion architectures for B2B SaaS.

Feature pages, pricing pages, comparison pages, case studies, integrations. Built so each page does its job in the buyer's journey.

Sales-enablement microsites.

A dedicated, password-protected mini-site for a specific account, with their problem named and your fit demonstrated. The asset that closes the last 10% of enterprise deals.

Conversion-rate rebuilds for sites that underperform.

We audit the funnel, identify the friction, rewrite the copy, redesign the high-leverage pages, and re-tune the forms.

Free

The offer

Before we build — the Conversion Call.

A free 30-minute call. You bring the current site URL and your conversion goals. We come prepared — we've already screen-captured your site, read the copy, and run a basic funnel analysis before we hop on. Within 48 hours of the call, you receive a written page-by-page memo with three things changeable today and one thing changeable strategically.

You walk out with (in writing):

  • The three messaging friction points costing you the most pipeline
  • Specific copy rewrites for your hero and primary CTA
  • A rewrite-vs-redesign-vs-rebuild recommendation
  • Permission to never speak to us again if the answer is "keep what you have"
"They rewrote three pages and our inbound qualified leads doubled the next quarter. Same traffic. Different site."

Ready to talk

The best marketing site you can buy is the one that closes deals while you sleep.
