A typical 'beautiful' website rebuild ships with: heavy hero video that tanks Largest Contentful Paint, parallax animations that break Cumulative Layout Shift, custom fonts blocking render, marketing pixels firing client-side and slowing time-to-interactive, and a checkout or contact form designed by the brand team instead of the conversion team. Six months after launch, conversion rate is 15% lower than the old site.
Three patterns show up in nearly every site rebuild we audit. One: Core Web Vitals failing on mobile, dragging down both SEO rankings and paid landing page Quality Score. Two: tracking architecture bolted on after the design was finalised — GA4 events misfiring, conversion duplicating, attribution broken from launch. Three: CMS choices made by the marketing team (Webflow! WordPress! Squarespace!) without consultation on what the content team actually needs to maintain it long-term.
Performance marketing and web development are the same conversation. The site is where every dollar of ad spend lands. The site is what every SEO ranking points to. The site is where conversions either happen or don't. Building it without treating performance, conversion, and measurement as primary requirements is how you spend $80k on a rebuild that loses you revenue.
That's what we don't do.
