What this service does

Designed Mobile-First.
Engineered to Compound.

Mobile devices generate more than half of global web traffic and Google moved to mobile-first indexing in 2019. Most agencies still design at 1440 pixels first and patch the breakpoints at the end. That order is backwards. We start on the phone, prove the layout works there, and scale up.

Outcome 01

+25 to 45% mobile conversion gain.

Median range across active responsive rebuild engagements. The cause is usually page speed, not creative.

Outcome 02

Sub-1.8s mobile LCP.

Largest Contentful Paint under 1.8 seconds on a throttled 4G profile. INP under 200ms. CLS under 0.05. Launch criteria, not stretch goals.

Outcome 03

WCAG 2.1 AA on day one.

Accessibility baked into the design system. Colour contrast, focus order, keyboard navigation, and screen-reader landmarks tested before launch.

Why teams pick us

Three Reasons This
Beats the Alternatives.

Most options sit in four buckets: the freelance designer, the template platform, the big agency, the internal team. We sit between them with the strengths of each and the weaknesses of none.

One strategist from sales call to launch.
Reason 01

One strategist from sales call to launch.

No junior account managers. The strategist on the sales call is the strategist on the project, same person every week, every demo, across SaaS, healthcare, manufacturing, and ecommerce.

Fixed-price pricing published on the page.
Reason 02

Fixed-price pricing published on the page.

Fixed scope, fixed timeline, pricing right above the fold. Change requests get scoped and quoted separately. What you sign is what you pay.

You own the work end to end.
Reason 03

You own the work end to end.

Code, design system, documentation, vendor accounts, all transferred to you on day one. Every asset in your name. Open-source CMS you can hire developers to maintain.

Who this is for

The Fit Below Tells You
in 60 Seconds Whether the Call Is Worth Booking.

Most responsive web design services pitch every business that walks in the door. We do not. Three profiles below are where the work moves the number most.

Service businesses, 5 to 200 employees.
Segment 01

Service businesses, 5 to 200 employees.

The current site embarrasses you in sales calls. New hires cannot update it. Phone bounce rate is north of 60 percent. A stakeholder in your org has been through one bad agency engagement and is allergic to surprises. This is the right fit for a responsive website design agency built around fixed scope.

Multi-location or multi-service businesses.
Segment 02

Multi-location or multi-service businesses.

Dental groups, optometry chains, regional accounting firms, multi-state law practices. You need location pages that rank locally and a CMS workflow your team can keep updated week to week.

Regulated industry firms.
Segment 03

Regulated industry firms.

Legal, healthcare, financial advisory, manufacturing with ITAR. The site clears bar advertising rules, HIPAA, or FINRA disclosure before a visitor sees it. Compliance review is built into discovery, not bolted on at launch.

Responsive web design FAQ

Web Design
Questions Answered.

If your question is not here, book the 30-minute call. A web design strategist answers directly on the call.

What do responsive web design services actually include?+

Responsive web design services at Redefine Web include a mobile-first design system, cross-device testing, accessibility conformance, Core Web Vitals tuning, and a full CMS build. Every site launches responsive across mobile, tablet, and desktop, tested on real hardware.

  • Mobile-first design system (component library, style guide).
  • Responsive breakpoints at 360, 414, 480, 768, 1024, 1280, 1440, 1920px.
  • CMS build on WordPress, Webflow, Framer, or Next.js.
  • WCAG 2.1 AA accessibility conformance.
  • Core Web Vitals tuned for LCP under 1.8s and CLS under 0.05.
  • Schema markup, sitemap, 301 redirect map on launch.
How many devices does a responsive website design agency test on?+

Redefine Web tests responsive builds across 8 defined breakpoints plus real-hardware validation. Mobile at 360px, 414px, and 480px. Tablet at 768px and 1024px. Desktop at 1280px, 1440px, and 1920px.

Real hardware tested pre-launch:

  • Current iPhone (iOS Safari).
  • Current Android (Chrome and Samsung Internet).
  • Current iPad (Safari).
  • Windows laptop (Chrome, Firefox, Edge).
  • Mac (Safari and Chrome).

BrowserStack sweep across the last two versions of every major browser. Pre-launch QA covers real thumbs on real screens, not just DevTools emulation.

How much does a mobile-friendly responsive web design cost?+

Mobile-friendly responsive web design at Redefine Web starts at $2,900 fixed for a small-business Essential tier and scales up to $85,000 for a custom enterprise build. All pricing is flat, no hourly billing, no scope creep.

Rough guide by scope:

  • Essential (up to 5 pages, WordPress): $2,900 to $6,900.
  • Growth (up to 12 pages, WordPress or Webflow): $6,900 to $14,900.
  • Custom Build (25+ pages, integrations, CRM wiring): $18,000 to $45,000.
  • Enterprise (Next.js headless, ecommerce, multi-region): $45,000 to $85,000.

Every tier includes accessibility conformance, Core Web Vitals passing, and full ownership on handoff.

What CMS does the responsive web design company recommend?+

Redefine Web recommends WordPress by default for content-heavy sites, Webflow for design-driven brands with small content footprints, Framer for marketing sites, and Next.js with a headless CMS for enterprise and headless commerce. Recommendation is based on your team and stack, not on what we want to build.

Decision matrix:

  • WordPress. Content team edits daily, blog-heavy, plugin ecosystem needed.
  • Webflow. Design-driven brand, small team, marketing edits only.
  • Framer. Interactive marketing site, motion-heavy hero, no e-commerce.
  • Next.js + Sanity or Contentful. Enterprise scale, headless commerce, custom app integrations.
  • Sitecore or Adobe Experience Manager. Enterprise CMS lock-in already in place.
Do you migrate content from our old site?+

Yes. Content migration is in-scope on Custom Build and Enterprise tiers of Redefine Web's responsive web design services. Content gets audited first. About 1 in 3 pages typically gets retired during migration because it was not earning its keep.

What migration covers:

  • Full content audit (traffic, ranking, conversion data per URL).
  • Content cleanup and rewrites where needed.
  • 1:1 or many-to-1 URL mapping for 301 redirects.
  • Image optimization and WebP conversion.
  • Schema markup migration and expansion.
  • Internal link rebuild around the new site map.

Content freeze is 2 weeks before launch. Post-launch monitoring runs 90 days to catch any organic dips.

What about SEO during the responsive website transition?+

SEO on a responsive website design transition is protected by a full 301 redirect plan, schema migration, and Search Console monitoring for 90 days post-launch. Most clients see a 2-week organic dip, recovery to baseline by week 6, then growth above baseline by month 3.

SEO-preserving deliverables on every migration:

  • Full 301 redirect map (every old URL to a new URL, no 404s).
  • Schema markup ported and expanded.
  • Internal linking rebuilt around the new sitemap.
  • XML sitemap regenerated and submitted.
  • Search Console monitoring for 90 days.
  • Weekly reporting on Search Console coverage, indexing, and impression movement.

If organic dips longer than 30 days below baseline, we escalate and diagnose.

Will the responsive site be accessible?+

WCAG 2.1 AA accessibility conformance is the baseline on every Redefine Web responsive build. Contrast, focus order, keyboard navigation, screen-reader landmarks, alt text, accessible forms. Axe scans plus manual audit plus NVDA and VoiceOver testing.

Accessibility coverage:

  • Color contrast tested against 4.5:1 minimum (7:1 target).
  • Keyboard-only navigation across every interactive element.
  • Screen-reader landmarks and heading hierarchy validated.
  • Focus order matches visual reading order.
  • Form fields labeled, error states announced.
  • Alt text on every image, empty alt on decorative.

NVDA on Windows and VoiceOver on Mac and iOS run pre-launch. Documentation lives with the project so your team can defend the work if a demand letter arrives.

Can we keep our current hosting?+

Probably. Redefine Web reviews your host during discovery. If it is a managed WordPress host like WP Engine, Kinsta, or Pantheon, we migrate inside the same account. If it is shared GoDaddy or Bluehost, we recommend moving.

Hosting recommendations:

  • WP Engine ($30 to $290/mo, best all-round managed WP).
  • Kinsta ($35 to $325/mo, best performance).
  • Cloudways ($14 to $180/mo, developer-flexible).
  • Pantheon ($50 to $400/mo, enterprise + staging).
  • Vercel (Next.js, from $20/mo).
  • Netlify (JAMstack, from $19/mo).

Hosting cost lives with you and stays separate from the project fee. If your host bill is under $30/mo, you are probably on shared hosting that will slow the responsive build down.

How fast does the responsive website need to load?+

Redefine Web launches responsive builds with Core Web Vitals in the Google Good band as a launch criterion, not a stretch goal. Largest Contentful Paint under 1.8 seconds on a throttled 4G mobile profile. Interaction to Next Paint under 200 milliseconds. Cumulative Layout Shift under 0.05.

Performance targets tuned pre-launch:

  • LCP under 1.8s (Good band).
  • INP under 200ms (Good band).
  • CLS under 0.05 (Good band).
  • TTFB under 500ms on managed hosting.
  • Total page weight under 800KB above the fold.
  • Hero image served as WebP with sizes attribute and fetchpriority high.
  • JavaScript deferred where possible, no render-blocking scripts.
What if I want changes after the responsive website design launches?+

Two paths. Monthly maintenance retainer from $299/mo covers ongoing edits, security updates, and small new features. Or project-by-project work quoted as needed. Redefine Web does not bill hourly for either.

Maintenance retainer tiers:

  • Essential ($299/mo): monthly security updates, plugin updates, up to 4 edit tickets.
  • Growth ($599/mo): weekly updates, unlimited small edits, monthly performance report.
  • Scale ($1,299/mo): 24/7 uptime monitoring, hardened WAF, staging environment, dedicated engineer.

All maintenance runs on the client dashboard so ticket status is transparent. Larger new-feature scopes are quoted as a fixed-price statement of work with a written timeline.

Which industries have you built responsive web design services for?+

Redefine Web has launched responsive web design services for B2B SaaS, professional services, healthcare, dental, med spa, manufacturing, real estate, ecommerce, home services, beauty and skincare, food and beverage, apparel and fashion, and pet products.

Verticals we ship responsive builds for regularly:

  • Local practices (dental, chiropractor, optometry, med spa).
  • B2B (SaaS, professional services, manufacturing).
  • Consumer (beauty, food and beverage, apparel, pet, home services).
  • Ecommerce (DTC across every consumer vertical).
  • Real estate (single agent to multi-location brokerage).

If your industry has unusual compliance requirements (HIPAA, PCI, FINRA, SOC 2), we say so on the first call and either scope for it or point you to a specialist.

How long does a responsive web design project take?+

Responsive web design projects at Redefine Web launch in 4 to 16 weeks depending on tier. Essential in 4 to 6 weeks. Growth in 6 to 8 weeks. Custom Build in 8 to 12 weeks. Enterprise in 12 to 16 weeks. Every project runs on a signed timeline with no open-ended discovery.

Standard project phases:

  • Weeks 1 to 2, discovery and information architecture.
  • Weeks 3 to 5, design system and page templates.
  • Weeks 5 to 8, development and CMS build.
  • Weeks 8 to 10, content migration, integrations, QA.
  • Weeks 10 to 12, accessibility audit, performance tuning, launch.

Enterprise adds a design QA sprint, load testing, and multi-region launch. Timeline dependencies (content approvals, third-party integrations) are called out weekly so nothing hides.

What we will not do

Five Commitments
Most Agencies Refuse to Make.
