We build them as all three at once — fast, measured, and conversion-led. ## What modern website development actually is Website development for marketing has evolved through several distinct eras: the brochure-site era (1995-2008); the CMS era (2008-2018) dominated by WordPress and early ecommerce platforms; the Shopify + headless commerce era (2015-2024); and the AI-and-Core-Web-Vitals era (2020-2026) where Core Web Vitals became ranking signals, AI Overviews changed search behavior, and conversion infrastructure (server-side GTM, conversion APIs, attribution) became as important as the front-end. By 2026, the dominant platforms for marketing-driven sites are Shopify (commerce), Webflow (marketing sites), Framer (design-led sites), and headless setups with Next.js/Astro/Remix for performance-driven brands. The short answer first. For Montana companies, RGM delivers Website development the same way it does everywhere: diagnose the current state, set a testable plan, execute directly, and report plainly on results. ## Where website development sits in the marketing stack FIG. 01 — Website development across the marketing funnel The website is the convergence point of every marketing channel. SEO sends organic traffic to it; paid acquisition sends paid traffic to it; lifecycle CRM funnels traffic back to it; ABM and content programs drive consideration-stage traffic; the site has to convert each of these audiences at different stages. The mistake we routinely fix: sites built primarily for one audience (usually the marketing team that approved them) without explicit conversion-rate optimization for the actual incoming traffic mix. The brands compounding build sites that serve SEO-driven research traffic, paid-driven DR traffic, and lifecycle-driven repeat traffic with appropriate experiences for each. ## How modern marketing website mechanically works Mechanics: fast load times (LCP under 2.5s, INP under 200ms, CLS under 0.1) for Core Web Vitals ranking signals; structured data (Schema.org) for SEO and AI Overview citation; clean conversion infrastructure (server-side GTM, conversion APIs to every paid platform, Customer Match audience uploads); A/B testing platform (Statsig, GrowthBook, Optimizely, VWO); analytics (GA4 + warehouse export); accessibility (WCAG 2.1 AA minimum); responsive design across all viewport sizes; conversion-rate-optimized templates for landing pages, product pages, blog pages, and category pages. ## Conversion infrastructure and the modern measurement layer FIG. 02 — Website conversion infrastructure signal flow Modern marketing sites are measurement infrastructure as much as they are user experience. The build has to include: server-side [GTM](/learn/gtm/server-side-container/) container with conversion APIs to Meta + TikTok + Google + LinkedIn + Pinterest + Amazon; Customer Match audience upload integration; first-party data capture with email + SMS opt-ins; clean event taxonomy mirroring GA4 and product analytics; cookie consent management compliant with state and international privacy law; offline conversion upload pipelines tied to CRM and warehouse data. Without this infrastructure, every other marketing investment compounds suboptimally. #### RGM Experts Say Most marketing websites we audit have broken or absent conversion infrastructure. Pixel-only conversion tracking with no CAPI fallback; no Customer Match audience uploads; no server-side GTM; no event-id deduplication. The brand spends $200K-$2M/month on paid acquisition with broken plumbing. Building the conversion infrastructure during the website build — not after — is the single highest-leverage decision a marketing team makes during a site refresh. The cost of retrofit is 2-3x the cost of build-it-right. ## Website performance data and user behavior Modern website performance data: median ecommerce site CVR runs 2.5-4.5%; mobile-only sites typically 30-50% lower CVR than desktop; Core Web Vitals LCP impact on bounce — every 100ms of LCP improvement correlates with 1-2% conversion-rate lift; mobile-page weight in 2026 averages 2.5MB but top-performing sites stay under 1MB; modern users abandon at 3+ seconds page load. Accessibility lawsuits in the US grew 25% YoY 2020-2024; WCAG 2.1 AA compliance is now a legal requirement, not optional. ## Performance benchmarks by vertical FIG. 03 — Site CVR by Core Web Vitals tier Typical 2026 website benchmarks: ecommerce CVR 2.5-4.5%; lead-gen CVR 1.5-4.0%; B2B SaaS demo-request CVR 0.8-2.5%; LCP under 2.5s for top-quartile sites; INP under 200ms; CLS under 0.1; mobile traffic share 60-75%; mobile CVR typically 30-50% below desktop CVR. ## Top-performing verticals Website development is foundational across every digital business. Particularly high-stakes for: ecommerce (Shopify-based), B2B SaaS (Webflow / custom Next.js), content-driven SEO businesses (Webflow / WordPress / Astro), high-design brands (Framer / custom), local services (WordPress / Webflow with location pages), and headless commerce at scale. ## Modern website build components FIG. 04 — Modern website operating system Components: front-end platform (Shopify, Webflow, Framer, or headless Next.js/Astro/Remix); design system + component library; SEO foundation (structured data, internal linking, canonical tags, meta titles/descriptions); Core Web Vitals optimization; accessibility (WCAG 2.1 AA); conversion infrastructure (server-side GTM, CAPI, Customer Match, offline conversion uploads); analytics (GA4 + product analytics + warehouse export); A/B testing platform; cookie consent management; CDN and caching. ## Website development patterns that defined the era Notable modern website patterns: **Shopify**'s template ecosystem and theme architecture defined ecommerce site economics. **Webflow**'s visual development platform demonstrated marketing-team-owned site infrastructure. **Framer**'s design-led builder showed brand-first site design. **Vercel** + Next.js demonstrated headless commerce at performance scale. **Allbirds**'s mobile-first Shopify experience. **Glossier**'s editorial-led ecommerce design. **Notion**'s site as product experience. **Linear**'s industrial-design B2B site standard. ## Our process Days 1-30: site audit covering Core Web Vitals, accessibility, structured data, conversion infrastructure, A/B testing platform integration, design system status. Days 31-90: rebuild conversion infrastructure (server-side GTM + CAPI + Customer Match), fix Core Web Vitals issues, install structured data across all templates, accessibility remediation, A/B testing platform integration. Days 91-180: scale CRO program with weekly experiments, monthly Core Web Vitals reviews, quarterly accessibility audits. ## Funnel design and behavioral triggers Funnel architecture: homepage for brand + value-prop introduction; category and product pages for ecommerce conversion; landing pages for paid traffic conversion; blog and content pages for SEO traffic; about/team pages for trust and B2B research traffic; checkout and post-purchase pages for transactional flow. Each template optimized for its specific traffic mix. ## Creative and execution moves that lift performance - Server-side GTM + CAPI built during the rebuild — not after. - Core Web Vitals under benchmark thresholds. LCP under 2.5s, INP under 200ms, CLS under 0.1. - Structured data on every template — Article, Product, BreadcrumbList, FAQPage, Organization. - Mobile-first design and testing. 60-75% of traffic is mobile. - A/B testing platform integration before launch. Build CRO into the foundation. - Accessibility (WCAG 2.1 AA) as a baseline, not a retrofit. #### RGM Experts Say Most website rebuilds we inherit produced beautiful sites with broken measurement infrastructure. The marketing team approved the visual design; nobody approved the conversion plumbing. Six months later the team realizes paid social attribution is broken, Customer Match audiences aren't populated, and the cookie consent banner is breaking GA4 tracking. The fix is 6-12 months of retrofit work. Build the measurement infrastructure during the build, not after — this is the single most important decision in a marketing site project. ## When we scale a campaign Site investment compounds when: Core Web Vitals stay green, conversion-rate trends up via CRO program, paid acquisition CAC improves with cleaner attribution, SEO organic share-of-voice grows, and accessibility compliance holds. ## When we kill a campaign Site investments deprecate when: Core Web Vitals regress past green thresholds, conversion infrastructure breaks, accessibility violations accumulate, or design-system drift breaks template consistency. ## Tracking, data feeds, and tools Tracking stack: GA4 + product analytics, server-side GTM, CAPI / Events API to every paid platform, BigQuery warehouse export, Looker reporting, A/B testing platform with statistical rigor, Core Web Vitals monitoring (CrUX + RUM). Tools: Shopify / Webflow / Framer / Next.js / Astro for front-end; server-side GTM via Stape or self-hosted; Statsig / GrowthBook / Optimizely / VWO for A/B testing; Lighthouse / WebPageTest / SpeedCurve for performance monitoring; axe / Lighthouse accessibility audits. ## The KPIs that drive ad-ops decisions Daily: Core Web Vitals trends, conversion-rate by template, A/B test queue health. Weekly: experiment cadence, design-system compliance. Monthly: accessibility audit, structured-data validation. ## The KPIs we report to clients Total conversion rate by template, organic search traffic and ranking, paid-attributable conversions via clean CAPI, A/B test win rate, Core Web Vitals scores, accessibility compliance. #### RGM Experts Say The marketing websites compounding in 2026 are the ones built as conversion-and-measurement infrastructure first, design second. The brands struggling are the ones who treated the site rebuild as a brand-refresh project and inherited broken plumbing. The cost of doing it right the first time is 10-20% of doing it wrong and fixing it later. Marketing leadership has to own the technical scope of the build, not delegate it to whoever picked the designer. ## How we work with Montana businesses We work with businesses headquartered in Montana and across Helena and across the state.
