Build a high-converting agency site with Next.js and Formgrid for $15K impact

Launching a professional agency landing page doesn’t require a five-figure budget or a month of development time. With the right stack—Next.js for performance, Formgrid for lead capture, and Google Sheets for real-time tracking—you can build a high-converting site that turns visitors into clients from day one.

This guide walks you through creating a multi-section agency landing page that not only looks premium but also includes a seamless lead capture and tracking system. No backend, no CRM, and no Zapier subscriptions are needed. By the end, you’ll have a page ready to deploy for your agency or clients, complete with a dashboard that shows every enquiry’s status and source.

Why your agency landing page isn’t converting (and how to fix it)

Most agency websites fail to convert because they treat the contact form as an afterthought. It’s often hidden on a separate Contact page, forcing visitors to take an extra step before they can enquire. Even if they land on the homepage, a lack of clear next steps leaves them unsure how to proceed.

Another common issue is the absence of a lead management system. When enquiries arrive via email, they risk getting buried under inbox noise. Agencies struggle to track which leads were followed up, which went cold, and which marketing channels brought in paying clients. This lack of visibility makes it impossible to refine your strategy.

Finally, many sites fail to build trust fast enough. Visitors need to see concrete results—specific revenue figures, client names, and measurable outcomes—within seconds of landing. Vague claims about passion for design won’t cut it. This tutorial addresses all three problems by combining a polished design with an integrated lead tracking system.

What you’ll build: a tracked, conversion-ready agency page

By following this tutorial, you’ll create a multi-section landing page with:

• A hero section that highlights measurable results and a clear value proposition
• A services overview that showcases your offerings
• Social proof with client testimonials or case studies
• Transparent pricing packages
• A contact and quote request form at the bottom

Every form submission is captured by Formgrid, which automatically creates a tracked lead with a status of New. The lead appears in your Formgrid dashboard and syncs to a shared Google Sheet in real time. Your team can mark leads as Contacted, add notes, set follow-up reminders, and track conversions—all without writing a single line of backend code.

Prerequisites and setup

Before you start, ensure you have the following:

• Node.js 18 or higher installed on your system
• A Formgrid account (free tier available at formgrid.dev)
• A Google account for Google Sheets integration
• Familiarity with Next.js and React components

To initialize your project, run:

npx create-next-app@latest agency-landing \
  --typescript --tailwind --app
cd agency-landing
npm run dev

Verify the setup by opening ` in your browser. You should see the default Next.js starter page.

Step 1: Configure Formgrid for lead capture

Before writing any code, set up your Formgrid form to generate the endpoint you’ll need for submissions.

Log in to formgrid.dev and create a new form named Agency Enquiries or Proposal Request Form. Once created, navigate to the Overview tab and copy the endpoint URL. It will look similar to:

Save this URL—you’ll use it in your form component later. This endpoint will automatically capture and track every submission, converting it into a lead with a status of New.

Step 2: Structure the landing page with modular components

Replace the contents of app/page.tsx with a modular structure that separates each section into reusable components:

import Hero from '@/components/Hero'
import Services from '@/components/Services'
import SocialProof from '@/components/SocialProof'
import Pricing from '@/components/Pricing'
import ContactForm from '@/components/ContactForm'

export default function Home() {
  return (
    <main>
      <Navbar />
      <Hero />
      <Services />
      <SocialProof />
      <Pricing />
      <ContactForm />
    </main>
  )
}

Create a components directory inside your app folder and build each section as a standalone component. This modular approach keeps your code organized and makes future updates easier.

Step 3: Design the hero section with trust-building metrics

Create app/components/Hero.tsx and add a hero section that immediately establishes credibility with concrete results:

import Image from 'next/image'

const metrics = [
  { label: 'Revenue generated for clients', value: '$6.8M' },
  { label: 'Average increase in qualified leads', value: '214%' },
  { label: 'Projects shipped with measurable growth', value: '92' },
]

export default function Hero() {
  return (
    <section className="relative overflow-hidden bg-[#06070b] px-6 pt-28 pb-20 text-white md:pt-36">
      <div className="absolute inset-0 bg-[radial-gradient(circle_at_20%_20%,rgba(250,204,21,0.2),transparent_35%),radial-gradient(circle_at_80%_20%,rgba(56,189,248,0.15),transparent_30%)]" />
      <div className="relative mx-auto grid w-full max-w-6xl items-center gap-14 lg:grid-cols-[1fr_1fr]">
        <div>
          <p className="mb-5 text-xs font-semibold uppercase tracking-[0.32em] text-amber-300">
            Precision web design for serious growth
          </p>
          <h1 className="font-display max-w-3xl text-4xl font-black leading-[0.92] tracking-[-0.02em] text-white md:text-5xl lg:text-6xl">
            Your next website should feel premium and perform like a sales team
          </h1>
          <p className="mt-7 max-w-xl text-base leading-7 text-slate-300 md:text-lg">
            We design fast conversion-ready websites for agencies and software brands that need more demand from the same traffic.
          </p>
          <div className="mt-10 flex flex-wrap gap-4">
            <a href="#contact" className="rounded-full bg-amber-300 px-7 py-3 text-sm font-semibold text-black hover:bg-amber-200 transition-colors">
              Get a proposal
            </a>
            <a href="#services" className="rounded-full border border-slate-600 px-7 py-3 text-sm font-semibold text-white hover:bg-slate-800 transition-colors">
              How we work
            </a>
          </div>
        </div>
        <div className="relative h-96 w-full">
          <Image
            src="/hero-image.jpg"
            alt="Premium agency website mockup"
            fill
            className="object-cover rounded-lg"
            priority
          />
        </div>
      </div>
      <div className="mx-auto mt-16 grid max-w-6xl grid-cols-1 gap-8 sm:grid-cols-3">
        {metrics.map((metric, index) => (
          <div key={index} className="bg-slate-800/50 p-6 rounded-lg border border-slate-700">
            <p className="text-2xl font-bold text-white">{metric.value}</p>
            <p className="mt-2 text-sm text-slate-400">{metric.label}</p>
          </div>
        ))}
      </div>
    </section>
  )
}

This hero section combines a compelling headline, supporting copy, and quantifiable results to build instant trust. The gradient background and responsive layout ensure it looks polished across all devices.

Next steps: expand and deploy

With the hero in place, proceed to build the remaining components—Services, SocialProof, Pricing, and ContactForm—using the same modular approach. Each should reinforce the value proposition and guide visitors toward conversion.

Once all sections are complete, deploy your site using your preferred hosting provider. The lead capture system will start working immediately, with every enquiry tracked in Formgrid and synced to Google Sheets. This setup eliminates manual follow-ups and provides the data needed to optimize your marketing spend.

The result is a landing page that doesn’t just look professional—it performs like one, turning visitors into paying clients from the moment it goes live.
