Web Design Services Built on Data, Not Guesswork

At a Glance: LDA Interactive designs and builds websites — WordPress, Shopify, and custom web applications — using real user behavior data instead of design trends. A typical project runs $3,500–$50,000+ depending on platform and complexity, and takes 4–12 weeks on average from kickoff to launch. Every site we build starts with an audit of how real users actually navigate (heat maps, click-stream analysis), not assumptions about what looks good. We've delivered 750+ projects over 25+ years for businesses from local retailers to national e-commerce brands.

On this page: our process, what's included, how much it costs and why, which platform is right for you, a real client result, and answers to the questions we hear most often before someone hires us.

Why Most Web Design Advice Is Wrong

Most agencies talk about web design in terms of “beautiful” and “modern.” Those words don’t mean anything measurable, and they’re not what actually determines whether a website works.

What determines whether a website works is whether real visitors can find what they need, understand what to do next, and do it without friction — measured, not assumed. A site can be visually stunning and still convert poorly if the checkout button is in the wrong place, the mobile menu is confusing, or the page takes four seconds to load. We’ve seen this pattern across 750+ projects: the sites that underperform almost never fail on aesthetics. They fail on the invisible mechanics nobody notices until they measure them.

That’s why our process starts with data collection, not mood boards.

Our Process: From Insight to Impact

1. Discovery & Behavioral Audit

If you have an existing site, we start by auditing how real visitors actually use it — heat maps, click-stream data, and session recordings reveal where people get stuck or drop off. If you’re starting fresh, we study your industry’s user behavior patterns and your specific business goals before a single wireframe is drawn.

2. Data-Informed Design

Wireframes and visual design decisions are made based on what the behavioral data shows, not on trend-chasing. Every layout choice — navigation structure, button placement, page hierarchy — is a hypothesis we can defend with evidence, not a preference.

3. Development

We build for speed, security, and mobile responsiveness from the first line of code — not as a post-launch fix. Every site is built to pass Google’s Core Web Vitals (loading speed, interactivity, visual stability), since these are confirmed ranking factors and directly affect conversion rates.

4. Launch & Continuous Optimization

Launch is the start of the data set, not the end of the project. We monitor real user behavior after launch and make evidence-based refinements — because a website’s first version is a hypothesis, not a finished product.

What’s Included

Every LDA web design project includes:

  • Custom design based on behavioral data analysis (not a template)
  • Full mobile responsiveness, tested across real devices
  • Core Web Vitals-optimized development (speed, interactivity, stability)
  • On-page technical SEO foundation (URL structure, heading hierarchy, image alt text, schema markup)
  • Cross-browser testing before launch
  • 3 rounds of design revisions
  • Post-launch support window: 45 days
  • Basic analytics setup (Google Analytics 4, Google Tag Manager)

Not included by default (available as add-ons): copywriting, professional photography, ongoing SEO/content marketing, paid advertising management.

How Much Does a Website Cost?

Pricing depends on platform and complexity, not a flat rate:

Project Type Typical Range Typical Timeline
Standard WordPress or Shopify business site $3,500–$8,500 4–8 weeks
E-commerce site (Shopify/WooCommerce) $8,000–$20,000 6–10 weeks
Custom web application $10,000–$50,000+ 8–16 weeks

Three things move the price within these ranges: number of unique page templates, depth of custom functionality (integrations, membership systems, custom databases), and content volume you’re providing versus what we need to create. We give a fixed quote after a discovery call — not an estimate that grows once the project starts.

Which Platform Is Right for You?

Platform Best for Avoid if
WordPress Content-heavy sites, blogs, service businesses, sites needing highly custom functionality You need a simple store with minimal content and want the lowest possible maintenance
Shopify Businesses primarily selling physical products online You need extensive content management beyond a standard storefront
Custom Web Application Client portals, booking systems, internal tools, workflows no off-the-shelf platform handles Your needs fit a standard website — custom development is the highest-cost, highest-complexity option

We recommend a specific platform after understanding your business model and goals during discovery — not before.

Real Result: Agraria San Francisco

Agraria San Francisco, America’s oldest luxury home fragrance brand — founded in 1970 and sold in Bergdorf Goodman, Neiman Marcus, Saks Fifth Avenue, and other top retailers worldwide — came to LDA Interactive running on Magento 2, a platform that had become expensive to maintain, unpredictable across updates, and slow to load. For a brand built on premium positioning, a sluggish, dated e-commerce experience worked against the brand itself.

We migrated Agraria’s store from Magento 2 to Shopify Plus, then installed heat mapping and behavioral analytics to identify exactly where visitors were losing interest or abandoning their carts — replacing assumptions with evidence. Design and UX changes were made based on what that data showed, not on general best practices alone.

Results:

  • 70% reduction in page load time
  • 18% increase in conversion rate
  • 22% reduction in cart abandonment
  • 34% increase in mobile conversion rate

The migration was completed in 2022, and the platform and conversion improvements have held up over multiple years of continued growth — a Shopify Plus foundation that’s scaled with the brand rather than needing another costly migration.

Signs You Need a New Website (or a Redesign)

You likely need a new site or redesign if:

  • Your site takes more than 3 seconds to load on mobile
  • Your bounce rate is high relative to your traffic, or you don’t know your bounce rate
  • The site hasn’t been updated in 3+ years
  • You’re manually doing something (bookings, quotes, inventory) that should be automated
  • Your competitors’ sites look and function noticeably better
  • You’re not sure what action you want a visitor to take when they land on your homepage

If none of these apply, a full redesign may not be necessary — a targeted optimization pass might solve the actual problem for less.
