The problem

Most of your buyers are on a phone. Your site was built for a desk.

Built for the office monitor

Your website looks right on the office monitor, but on a phone the menu misbehaves, the text crowds, and the contact form takes three attempts.

Visits without enquiries

You pay for traffic and post for reach, yet the enquiries never match the visits, and most of those visits are mobile.

Responsive in name only

You were told you have a responsive website, but nobody has shown you how it actually performs on the phone in a buyer's hand.

The solution

Do It Digital builds mobile-first websites that adapt to any screen, pass Google's Core Web Vitals, and carry conversion tracking from day one, so you can see the enquiries each page produces.

One site, one build, working properly on the phone in your buyer's hand and on the laptop on their desk.

Fit

Is this for you?

This is for you if

  • Most of your visits are mobile, and the enquiries never match the traffic.
  • You run a professional services firm, restaurant, retail or trades business, and the website has to produce enquiries.
  • You were told your site is responsive, but nobody has shown you how it performs on the phone in a buyer's hand.

It is not for you if

  • A simple brochure site on an off-the-shelf responsive website builder genuinely covers it, and we will say so.
  • You want a design award more than enquiries you can count.
  • You are after a quick template shrink rather than a mobile-first build.

We audit your current site first, including speed and Core Web Vitals, then recommend the smaller of the two jobs that actually fixes the problem. If we are not the right fit, we will tell you on the call.

The build

Responsive web design services, standard in every build

As a responsive website design company we treat the phone as the first screen, not the shrunken afterthought. Here is what that means in a build.

Mobile-first build

The smallest screen first

Every page is designed for the smallest screen first, so the phone version is the real site, not a compromise.

Core Web Vitals, passed and proven

Google's thresholds, passed

We set speed budgets during the build and test against Google's thresholds before launch, because slow pages lose rankings and buyers alike.

Phone to widescreen

Grids, breakpoints and image sizes that adapt to any device, so nothing cracks between a phone and a widescreen.

Outcomes

What you get out of it

A site that reads well and converts on the phone, where your buyers already are.

Pages that pass Core Web Vitals, so speed feeds your rankings instead of eating them.

Enquiries you can count, with tracking that shows which pages produce them.

One website that works on every screen, with no separate mobile version to maintain.

Process

How we work

  1. 01

    Audit and strategy

    We map who buys from you, which devices they use, and what they search, then test your current site's speed and mobile behaviour.

    Outcome

    You sign off a brief and sitemap before anything is designed.

  2. 02

    Design, phone first

    Pages are designed for the small screen first and you review them at real sizes, not just a desktop mock-up.

    Outcome

    You approve the design before we build.

  3. 03

    Build and test

    A fast, mobile-first build with disciplined web development underneath: fluid layouts, flexible images, Core Web Vitals checked on real devices.

    Outcome

    A finished site, tested and ready for your sign-off.

  4. 04

    Launch and report

    We launch, monitor, and send a monthly report covering traffic, enquiries and speed, so you can see what the site produces. You own everything we ship. The care plan is optional, never a lock-in.

    Outcome

    A live site and numbers you can act on.

The difference

The usual way vs the did way

Without did.

  • Responsive claimed as a checkbox
  • A separate mobile site to maintain
  • Speed checked once at launch
  • Forms that fight thumbs
  • Traffic reported, enquiries guessed

With did.

  • Designed for the phone first
  • Core Web Vitals passed and shown
  • One build, every screen
  • Speed budgeted and reported monthly
  • Tap-sized buttons and short forms
  • Conversion tracking from day one

The stakes

Why mobile performance decides your rankings.

Responsive web design stopped being a differentiator years ago; what separates sites now is how well the responsive build performs.

Speed, stability and mobile usability feed the rankings that decide whether you are seen at all. For the professional services firms, restaurants, retailers and trades businesses we work with, that gap is the difference between a full calendar and a quiet week.

A mobile-first build that passes Core Web Vitals is not a technical nicety. It is how the phone in your buyer's pocket becomes the front door of your business.

Your buyers did not lower their standards when they picked up the phone.

FAQ

Questions.

What is responsive web designing?

Responsive web designing is the practice of building one website that adapts its layout, images and navigation to whatever screen it is viewed on, from a phone to a widescreen monitor. Instead of a separate mobile site, a single build uses fluid grids, flexible images and breakpoints to rearrange itself, so buttons stay tappable and text stays readable everywhere. Google indexes the mobile version of a site first, which makes responsive design a ranking matter as well as a usability one. Every website we build is responsive as standard, designed for the phone first and then scaled up, with speed and layout tested against Core Web Vitals before launch.

What are the 9 principles of responsive web design?

The nine principles most often cited are fluid grids, flexible images and media, breakpoints, mobile-first thinking, content priority, scalable typography, touch-friendly targets, performance, and testing on real devices. In practice they reduce to one idea: design for the smallest screen first, then let the layout earn its extra space as the screen grows. The principles that most affect your enquiries are the unglamorous ones, performance and touch targets, because a slow page or a button too small for a thumb loses the visitor no matter how gracefully the layout flexes. We apply all nine on every build and measure the outcome against Google's Core Web Vitals rather than calling it done at launch.

Is responsive design still a thing?

Responsive design for websites is very much still a thing, but it has shifted from a selling point into a baseline. Google indexes the mobile version of your site first, and its Core Web Vitals measure how fast and stable pages feel on real devices, so a site that behaves badly on a phone is quietly fighting its own rankings. The bar has also risen: passing on a phone is no longer about a layout that squeezes down, it is about speed, stable loading and forms a thumb can complete. Responsive design should never be a paid extra; it is simply what a properly built website is.

How much does a responsive website cost?

A responsive website should not cost extra, because responsiveness is a property of a properly built site rather than a bolt-on. What you pay for is the build itself: our Starter Web Kit is a fixed project from $1,999 for an AI-accelerated five-page build, Business Web Pro is $4,999 for a bespoke Figma design of around ten pages, and Growth Site starts from $9,999 with keyword-mapped SEO architecture included. All three are mobile-first as standard and priced as fixed projects, so the number is agreed before any work starts and never moves after the fact. The packages on this page show how we structure it as a responsive website design company, and on a call we map your scope to the right tier.

Can you make my existing website responsive?

Yes, in most cases an existing site can be rebuilt to a mobile-first standard without starting your brand from scratch. The right route depends on what is underneath: a reasonably modern site can often be refitted on its existing platform, while an ageing build is usually faster and cheaper to rebuild properly than to patch page by page. We audit the current site first, including speed and Core Web Vitals, then recommend the smaller of the two jobs that actually fixes the problem. That audit happens on the strategy call, so you know which route you are in before spending anything.

Do you use a responsive website builder or build custom?

A responsive website builder can be the right answer for a simple brochure site, and when it is, we say so rather than sell a bigger build. For most B2B businesses we build custom, often on WordPress, because owned code gives you control over speed, structure and Core Web Vitals that template builders make difficult. The practical test is whether your website needs to win rankings and produce enquiries. If it does, a custom mobile-first build earns its keep many times over; if it genuinely does not, a builder will do for now, and we will tell you that on the call rather than after an invoice.
