Why We Chose React over Vanilla JS for Marketing Sites
There is a popular argument that marketing sites should be built with vanilla HTML and JavaScript to keep bundles small. We disagree. After shipping dozens of high-conversion sites, we keep coming back to React. Here is why.
Components beat partials
A landing page is not one page — it is a hero, a marquee, three feature blocks, a testimonial slider, a pricing table, and a footer. With React, each of these is a single source of truth that we can drop onto any page with confidence.
Trying to keep ten near-identical hero variants in sync across plain HTML files is where bugs and visual drift live. Components kill that whole class of problem.
Modern tooling is not the bottleneck
Vite, code-splitting, and tree-shaking mean a well-built React marketing site routinely scores 95+ on Lighthouse. The bundle a visitor actually downloads is small because most of the work happens at build time.
Combine that with image optimization, prefetching links, and font-display: swap, and the user experience is indistinguishable from a static HTML site.
Animation and interactivity are first-class
Marketing sites today are not just text. They have scroll-driven animations, marquees, hover micro-interactions, and embedded product previews. Framer Motion, GSAP, and React Three Fiber make these trivial to wire up — and easy to maintain.
Doing the same in vanilla JS turns into a sprawl of one-off scripts that nobody wants to touch six months later.
When we don't reach for React
If a project is one static page with no shared components and no interactive elements, plain HTML is fine. We have shipped those too. The moment a second page or a second hero variant appears, React pays for itself.
Frequently asked questions
- Why use React for a marketing site instead of plain HTML?
- Marketing pages are made of repeated components — heroes, feature blocks, testimonials, pricing tables. React makes each a single source of truth, killing the visual drift and bug class that comes from copy-pasting partials across HTML files.
- Doesn't React make marketing sites slow?
- No. With Vite, code-splitting, tree-shaking, and image optimization, a well-built React marketing site routinely scores 95+ on Lighthouse. Most heavy work happens at build time and the runtime bundle a visitor downloads is small.
- What about animations and interactivity?
- Modern marketing sites need scroll-driven animation, marquees, micro-interactions, and embedded product previews. Framer Motion, GSAP, and React Three Fiber make these trivial in React; in vanilla JS they become a sprawl of one-off scripts.
- When does Aqib Ops not use React for a site?
- If a project is a single static page with no shared components or interactive behavior, plain HTML is fine and we ship it that way. The moment a second page or a second hero variant appears, React pays for itself.
- Does React hurt SEO for marketing sites?
- Not when the site is prerendered. Aqib Ops React sites are statically prerendered at build, so crawlers and AI engines receive fully rendered HTML, full schema, and per-route metadata without executing JavaScript.
