Websites Built to Convert Traffic Into Leads, Customers, and Revenue

Your website is where every other marketing channel lands. If it’s slow, hard to navigate, or doesn’t convert, every dollar you spend on SEO, paid, and content underperforms. THAT Agency builds websites designed to do what your marketing needs them to do — fast, accessible, SEO-ready, and conversion-optimized from day one.

How Web Design Drives Conversions and Multiplies Marketing ROI

A website’s job isn’t to look good — it’s to convert. A visitor who finds your site through organic search, a paid ad, or a social post has already shown intent. The website’s job is to make the next step obvious, frictionless, and fast enough that they don’t leave before they take it. Most websites fail at one or more of those three things, and the cost shows up in every channel’s performance metrics, not just direct website analytics.

At THAT Agency, web design means strategy, UX, visual design, development, and performance optimization working together toward one outcome: a site that turns more of its traffic into leads and customers. We build on WordPress, HubSpot, Shopify, and Webflow. We optimize for Core Web Vitals, mobile performance, and WCAG 2.1 Level AA accessibility. We implement schema markup and AI-search-ready content structure from the build rather than retrofitting them after launch. And we set up conversion tracking and analytics correctly so you can see what the site is actually producing.

Every website we build is also the foundation for everything else — the landing pages that paid campaigns need, the content architecture that SEO depends on, the forms and flows that email automation uses. Getting the website right makes every other marketing investment work harder.

What Our Web Design Services Include

Seven areas of work built to create websites that convert traffic and support your entire marketing strategy.

THAT Agency handles every part of building a high-converting website, from strategy and UX through visual design, development, conversion optimization, performance, and accessibility.

Web Design Strategy & Planning

Every project starts with understanding your business goals, target audience, and competitive landscape before a single wireframe gets drawn. We define KPIs tied to business outcomes rather than design preferences, map out the conversion funnel your site needs to support, develop the information architecture and sitemap, and establish the content strategy and messaging framework. This work determines whether a redesign improves performance or just updates the visual treatment — most redesigns that fail do so because this step was skipped.

Goal:Build a strategy that gives every design and development decision a reason to exist, and gives the launched site a clear job.

User Experience Design

UX design is the work of making the right action obvious and the wrong action difficult. We map user journeys from entry point to conversion, wireframe and prototype before committing to visual design, structure navigation for clarity rather than internal logic, and design forms and conversion flows that minimize friction. Accessibility is built into the UX layer — keyboard navigation, screen reader compatibility, and WCAG 2.1 Level AA compliance — rather than addressed as a compliance checkbox at the end of the project.

Goal:Design layouts that move users through pages efficiently, and convert them at every meaningful step.

Visual Design & Branding

We create modern, on-brand visual designs that establish credibility and guide attention toward conversion rather than away from it. Custom design tailored to your brand, style guide and design system development for consistency across the site, typography and color decisions made for readability and hierarchy rather than aesthetics alone, and responsive design that holds up cleanly across every device size. The visual design serves the conversion goal — it doesn’t compete with it.

Goal:Build a visual identity that earns trust in the first three seconds, and reinforces it across every page.

Web Development & CMS

We build clean, fast, secure, and standards-compliant websites. CMS integration on WordPress, HubSpot, Shopify, or Webflow based on your team’s capabilities and your marketing stack’s requirements. Core Web Vitals optimization built into development rather than patched after launch. Mobile responsiveness and cross-browser compatibility tested before delivery. Schema markup and structured data implemented from the build. Security best practices and SSL as standard.

Goal:Pick the right platform for the actual project, and build it cleanly enough that the team can maintain it after we hand it off.

Conversion Optimization (CRO)

CRO is ongoing work, not a one-time decision made at launch. We analyze conversion funnels to identify where visitors are dropping off and why, run A/B tests on design variations, content, and CTAs with enough traffic to produce statistically meaningful results, use heat mapping and session recording to understand actual user behavior rather than assumed behavior, and optimize forms and landing pages continuously based on what the data shows.

Goal:Stop guessing about what works, and continuously improve conversion rates with data.

Website Performance & Core Web Vitals

Site speed is a conversion factor, an SEO factor, and a Core Web Vitals factor simultaneously. We optimize Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) to meet Google’s “Good” thresholds — LCP under 2.5 seconds, INP under 200ms, CLS under 0.1. That means image compression and WebP conversion, code minification, lazy loading, deferred script loading, CDN implementation, and caching strategy built in from the start.

Goal:Hit Google’s “Good” Core Web Vitals thresholds, and protect rankings, conversion rate, and the user experience all at once.

Website Accessibility

WCAG 2.1 Level AA compliance reduces legal exposure, improves SEO through better semantic structure, and makes your site usable by the full range of people who visit it. We build keyboard navigation support, screen reader compatibility, proper color contrast ratios at a minimum of 4.5:1, alternative text for images, and accessible form labels and error messages into every project — not as an afterthought but as a design and development standard.

Goal:Build a website everyone can use, and that doesn’t expose your business to accessibility lawsuits.

Who Our Web Design Services Are Built For

Web design at THAT Agency is built for businesses that need their website to function as a genuine marketing asset — not a digital brochure that sits unchanged for four years.

We regularly work with local businesses establishing a professional online presence and generating leads from local search; B2B service providers converting qualified traffic into consultation requests and pipeline; eCommerce brands optimizing product pages and checkout flows for conversion rate and average order value; multi-location companies managing consistent brand presence across multiple market-specific sites; and businesses in competitive categories like legal, healthcare, and professional services where website credibility is a direct factor in whether a prospect makes contact.

If your current site is underperforming the traffic it receives — visitors arriving but not converting — that’s the problem we’re built to solve.

Start Building a Website That Works as Hard as Your Marketing

We’ll start with a straightforward conversation about your current site, what it’s producing, and what a website built around your actual conversion goals and marketing stack would look like. No pitch deck. No pressure.

How Our Web Design Process Works

Step 1. Discovery and Strategy

We start with stakeholder interviews, business goal definition, audience research, competitive analysis, and a content audit of your existing site where applicable. Platform selection, technical requirements, and conversion goals are all defined before design begins. This phase determines the architecture and strategy that everything else is built on.

Step 2. Design and Development

We move from information architecture and wireframes through visual design and prototyping, with client review built into the process at each stage. Development follows approved designs with performance optimization, accessibility, and SEO implementation built in throughout. Quality assurance and cross-device testing happen before anything goes to launch review.

Step 3. Launch and Optimization

Pre-launch testing covers performance, functionality, cross-browser compatibility, and accessibility. Analytics and conversion tracking are implemented and verified before go-live. Post-launch monitoring identifies early performance issues. Ongoing CRO work — A/B testing, heat mapping, form optimization — continues after launch because a website’s conversion rate at launch is a starting point, not a ceiling.

Why Choose THAT Agency for Web Design

Most web design agencies fall into one of two patterns we’ve watched fail. The design shops build gorgeous sites that win awards and tank rankings, slow load times, no schema, ignored Core Web Vitals, accessibility violations, content that doesn’t structure for AI. Or the dev shops build technically clean sites that nobody wants to use, flat design, generic templates, no conversion thinking, brand voice nowhere. We’ve watched businesses pay six and seven figures for both outcomes.

Three things set us apart:

We design for conversion, not awards. Every layout decision is tied to what we know about how real users move through pages. User testing, heat mapping, conversion analysis, the boring work that determines whether the site actually performs.
We build for performance, accessibility, and AI search from day one. Core Web Vitals targets are part of the spec. WCAG 2.1 Level AA is the baseline. Schema markup and AI-search-ready content structure are in the build, not the wishlist.
We don’t disappear after launch. The highest-ROI work happens post-launch, A/B testing, landing page refinement, content additions, performance tuning. Most agencies hand over a site and walk away. We treat launch as the start of optimization.

The result: a website that looks current, performs fast, ranks well, and earns its place as where everything else lives or dies.

Web Design FAQs

Your Questions Answered

Common questions businesses ask before partnering with a website design company.

What does a web design company actually do?

A web design company plans, designs, builds, and optimizes websites. The work spans strategy (business goals, audience research, information architecture), UX design (wireframes, prototypes, user journeys), visual design (branding, typography, custom graphics), development (clean HTML/CSS/JS, CMS integration, performance), conversion optimization (A/B testing, form refinement, CRO), and ongoing maintenance. At THAT Agency, we deliver the full stack, from discovery through launch and continuous post-launch optimization.

How long does it take to design and build a website?

Timeline depends on scope and complexity. Simple marketing sites typically take 8–12 weeks from kickoff to launch. Mid-complexity sites with custom design, CMS integration, and meaningful content development usually take 12–16 weeks. Enterprise sites, ecommerce platforms, and custom applications take 16–24+ weeks. The biggest variable is content readiness, projects accelerate when copy, images, and approvals move quickly. We provide a detailed project plan with milestones upfront so timelines stay predictable.

What platforms do you build on?

Every major platform, and we recommend the one that actually fits the project. WordPress for content-heavy marketing sites. HubSpot CMS for B2B teams running inbound in HubSpot. Shopify and Shopify Plus for ecommerce. Webflow for design-heavy sites with modest CMS complexity. Custom builds on Next.js, Astro, or React when requirements demand it. Platform recommendation is part of every discovery, we don’t push you onto the platform we want to bill on.

Are your websites mobile-responsive?

Yes, every site we build is mobile-first by default. Over 60% of web traffic comes from mobile devices (StatCounter, 2024), and Google indexes the mobile version of your site first. We design and test on real devices across iPhone, Android, and tablet, not just dev-tool simulations. Mobile performance, touch targets, navigation, and form completion are tested as carefully as desktop.

Do you optimize websites for SEO?

Yes, SEO is built into every site from day one, not bolted on after launch. That includes semantic HTML, optimized title tags and meta descriptions, header hierarchy, schema markup (Service, FAQPage, LocalBusiness, Organization, BreadcrumbList), internal linking, XML sitemaps, robots.txt configuration, Core Web Vitals optimization, and mobile usability. We also build sites to be cited by AI search engines (ChatGPT, Perplexity, Google AI Overviews) through structured Q&A formatting and entity-rich content.

Can you redesign my existing website?

Yes. Redesigns are one of our most common projects. The process starts with a full audit of your current site, performance, SEO equity, content gaps, conversion paths, and analytics history. We then plan the redesign to preserve everything that’s working (high-value URLs, ranking pages, conversion paths) and fix what isn’t. Critical: a poorly executed redesign can destroy SEO rankings overnight. We protect rankings through detailed 301 redirect mapping, content preservation, and post-launch monitoring.

How much does a website cost?

Website costs vary significantly based on scope, complexity, custom design, integrations, and content requirements. A focused marketing site for a small business is a smaller investment than a multi-location, multi-language ecommerce platform with custom integrations. Every proposal includes a clear scope of work, timeline, and deliverables. Request a proposal and we’ll send a customized recommendation based on your specific goals and requirements.

Do you provide hosting and ongoing maintenance?

Yes. We offer managed hosting on enterprise-grade infrastructure (WP Engine, Kinsta, Vercel, Shopify) and ongoing maintenance plans. Maintenance includes security updates, plugin and core updates, backups, performance monitoring, uptime monitoring, broken link checks, and minor content updates. Many clients also retain us for continuous conversion optimization, A/B testing, landing page refinement, and ongoing improvements that keep paying off.

Are your websites accessible (ADA-compliant)?

Yes, accessibility is built into every site by default. We target WCAG 2.1 Level AA, which is the standard most U.S. courts reference for ADA compliance. That includes proper semantic HTML, keyboard navigation, screen reader compatibility, color contrast (minimum 4.5:1), alt text on images, accessible forms, and ARIA attributes where needed. Accessibility is a baseline, not a feature. It’s also a legal requirement and a meaningful SEO signal.

How is THAT Agency different from other web design companies?

Three things. We design for outcomes, not aesthetics, every decision is tied to a conversion metric, not personal preference. Every site we build is written to rank, SEO, accessibility, and AI search visibility are baseline requirements, not upsells. And we don’t disappear after launch, the highest-ROI work happens in the months after through continuous CRO, content additions, and performance tuning. Most agencies hand over a site and walk away. We treat launch as the starting line.
