Building a Modern Landing Page with Gatsby in 2025

Landing pages are critical for business success. Whether you’re launching a product, promoting a service, or capturing leads, your landing page needs to load instantly, look stunning, and convert visitors effectively. Gatsby, the React-based static site generator, has emerged as one of the best tools for building modern landing pages that check all these boxes.

In this guide, we’ll explore why Gatsby is perfect for landing pages and walk through the essential techniques for building pages that perform exceptionally well.

Why Choose Gatsby for Landing Pages?

Speed is the foundation of effective landing pages. Studies consistently show that even a one-second delay in page load time can reduce conversions by 7%. Gatsby’s static site generation approach means your landing pages are pre-rendered at build time, resulting in near-instantaneous page loads.

Gatsby’s performance advantages go beyond simple static HTML. It automatically optimizes images, implements code splitting, prefetches links, and generates Progressive Web App capabilities out of the box. These optimizations happen automatically, meaning you get exceptional performance without manual configuration.

SEO is another critical factor for landing pages. Gatsby generates static HTML that search engines can crawl easily, unlike client-side rendered applications that may struggle with SEO. Combined with built-in support for meta tags, structured data, and server-side rendering, Gatsby provides everything you need to rank well in search results.

Setting Up Your Gatsby Landing Page Project

Starting a new Gatsby project is straightforward. The Gatsby CLI provides starter templates that include common configurations and best practices. For landing pages, you’ll want a minimal setup that focuses on performance and conversion optimization.

Begin by installing the Gatsby CLI and creating a new project. Choose a starter that matches your needs, or start with a blank template if you prefer complete control. The key is selecting a foundation that won’t weigh down your landing page with unnecessary features.

Once your project is initialized, configure essential plugins for image optimization, SEO, and analytics. The gatsby-plugin-image plugin is crucial for landing pages, as images often constitute the largest portion of page weight. This plugin automatically generates responsive images, lazy loads them, and serves them in modern formats like WebP.

Designing for Conversion

A landing page’s design must guide visitors toward a single, clear action. Whether that’s signing up for a newsletter, requesting a demo, or making a purchase, every element should support this conversion goal.

Start with a compelling hero section. This above-the-fold area needs to immediately communicate your value proposition and include a clear call-to-action. Use large, readable typography and high-quality visuals that load instantly thanks to Gatsby’s image optimization.

Structure your content using the classic landing page formula: problem, solution, features, social proof, and call-to-action. Each section should be concise and focused. Gatsby’s component architecture makes it easy to create reusable sections that maintain consistent design while allowing flexibility for different landing pages.

Performance Optimization Techniques

While Gatsby is fast by default, you can optimize further for landing pages. Critical CSS should be inlined to eliminate render-blocking resources. Gatsby supports CSS-in-JS solutions like styled-components that can automatically extract critical CSS, or you can use traditional CSS with plugins that handle this optimization.

Minimize JavaScript wherever possible. Landing pages often don’t need heavy JavaScript frameworks or libraries. Consider whether each piece of interactivity is necessary, and implement simple features with vanilla JavaScript or CSS instead of large dependencies.

Implement resource hints to prioritize critical resources. The gatsby-plugin-preload-fonts plugin ensures custom fonts load quickly, while link prefetching (built into Gatsby) loads linked pages in the background, creating the illusion of instant navigation.

SEO Best Practices

Gatsby’s React Helmet integration makes managing SEO metadata straightforward. Create a reusable SEO component that accepts props for title, description, and image, then use it on every landing page. This ensures consistent SEO implementation while allowing page-specific customization.

Structured data helps search engines understand your content and can earn rich snippets in search results. Implement JSON-LD structured data for your landing page, including Organization, Product, or Service schema as appropriate. This extra context can improve click-through rates from search results.

Open Graph and Twitter Card meta tags are essential for social sharing. When someone shares your landing page on social media, these tags control how it appears. Include compelling images and descriptions that encourage clicks when shared.

Image Optimization

Images make or break landing page performance. The gatsby-plugin-image provides the GatsbyImage component, which handles responsive images, lazy loading, and modern format delivery automatically. Use it for all your images to ensure optimal performance.

For hero images and above-the-fold content, disable lazy loading to ensure immediate visibility. The loading=“eager” prop tells Gatsby to prioritize these images, preventing the awkward loading delay that can hurt first impressions.

Consider using SVG for icons and simple graphics. SVG files are often smaller than raster images and scale perfectly at any size. Gatsby can inline small SVGs directly in your HTML, eliminating additional HTTP requests.

Form Integration and Lead Capture

Most landing pages need forms for lead capture. Gatsby works seamlessly with form services like Netlify Forms, Formspree, or headless CMS solutions. Choose a service that fits your needs and budget.

Netlify Forms is particularly convenient for Gatsby sites deployed on Netlify. Simply add a data-netlify attribute to your form, and Netlify handles submissions automatically. No backend code required, and you get spam protection and notifications built-in.

For more complex form requirements, consider integrating with a CRM or marketing automation platform. Tools like HubSpot, Mailchimp, or ConvertKit offer APIs that work well with Gatsby. You can submit form data to these services client-side or through serverless functions for added security.

Animation and Interactivity

Subtle animations can make landing pages feel polished and professional, but they must be performant. Use CSS transitions and transforms for simple animations, as these can be GPU-accelerated and won’t impact performance.

For more complex animations, libraries like Framer Motion integrate beautifully with Gatsby. Keep animations purposeful—they should guide attention and enhance understanding, not distract. Entrance animations for sections as users scroll can create engaging experiences without overwhelming visitors.

Respect user preferences by checking for prefers-reduced-motion. Some users find animations disorienting, and respecting this preference shows attention to accessibility. A simple media query can disable animations for these users while preserving them for others.

A/B Testing and Analytics

Understanding how visitors interact with your landing page is crucial for optimization. Integrate analytics from the start to track key metrics like bounce rate, time on page, and conversion rate.

Google Analytics 4 integrates easily with Gatsby through plugins. The gatsby-plugin-google-gtag handles the installation and provides options for configuring events and tracking. Set up conversion goals to measure your landing page’s effectiveness.

For A/B testing, tools like Google Optimize or VWO can run experiments on your Gatsby landing pages. Test different headlines, images, or call-to-action buttons to continuously improve conversion rates. Even small improvements compound over time, significantly impacting your bottom line.

Mobile Optimization

More than half of web traffic comes from mobile devices, making mobile optimization non-negotiable. Gatsby’s responsive image handling helps, but you also need to consider touch targets, font sizes, and navigation patterns.

Use a mobile-first approach when designing your landing page. Start with the mobile layout and enhance it for larger screens, rather than trying to squeeze a desktop design onto small screens. This ensures mobile users get a first-class experience, not an afterthought.

Test on real devices whenever possible. Simulators and browser developer tools are helpful, but nothing replaces testing on actual phones and tablets. Pay attention to form inputs on mobile—they should be large enough to tap easily and should trigger appropriate keyboards.

Content Strategy

Content is the foundation of any landing page. Your copy needs to be clear, concise, and compelling. Use Gatsby’s support for MDX if you want to enhance markdown content with React components, allowing content writers to work in a familiar format while maintaining design consistency.

Focus on benefits over features. Visitors don’t care about what your product does—they care about how it solves their problems. Frame every feature in terms of the value it provides to users.

Social proof builds trust and credibility. Include testimonials, case studies, logos of well-known clients, or statistics that demonstrate your success. Gatsby makes it easy to query this content from various sources and display it effectively.

Deployment and Continuous Improvement

Gatsby sites deploy beautifully to platforms like Netlify, Vercel, or AWS Amplify. These platforms offer continuous deployment from Git, preview deployments for pull requests, and built-in CDN distribution. Your landing pages will load quickly for visitors worldwide.

Set up a deployment preview workflow that lets you review changes before they go live. This prevents broken landing pages and gives you confidence when making updates. Most platforms offer this feature by default with Gatsby projects.

Monitor your landing page’s performance after launch. Use tools like Google PageSpeed Insights or Lighthouse to track core web vitals. Set up alerts for performance regressions so you can address issues quickly.

Advanced Techniques

For landing pages that need personalization, Gatsby’s client-side routing and React hooks enable dynamic content based on URL parameters or browser storage. You can show different content to visitors from different campaigns without duplicating pages.

Implement internationalization if you target multiple languages or regions. The gatsby-plugin-react-intl or gatsby-plugin-i18n plugins make it straightforward to create localized versions of your landing pages, each with appropriate SEO metadata.

Consider implementing a headless CMS for content management. Tools like Contentful, Sanity, or Strapi integrate seamlessly with Gatsby, allowing non-technical team members to update landing page content while maintaining Gatsby’s performance benefits.

Common Pitfalls to Avoid

Don’t overload your landing page with content. Every additional element increases cognitive load and potentially reduces conversions. Be ruthless in cutting anything that doesn’t directly support your conversion goal.

Avoid large dependencies that inflate your JavaScript bundle. Check your bundle size regularly using gatsby-plugin-webpack-bundle-analyser. If a single animation library adds 50KB to your page, consider whether it’s worth the performance cost.

Don’t neglect accessibility. Your landing page should be usable by everyone, including people with disabilities. Use semantic HTML, provide alt text for images, ensure sufficient color contrast, and test with keyboard navigation. Good accessibility often correlates with better SEO.
