The website blueprint for a product-led SaaS.

Product in the first viewport, proof immediately after, pricing on the page. The full architecture and a master prompt to build it.

Free, no email gate, no watermark · assembled from a curated matrix, so nothing here is invented

Where this combination usually goes wrong.

Product-led sites describe features and hide pricing. Both are conversion taxes: the buyer who never starts the trial was lost at the claim, and hidden pricing filters out exactly the buyers you want.

The pack below assumes the most common starting problem for this pairing: people visit, then leave without doing anything. Change it on the live generator.

01 · The positioning brief

SaaS buyers punish vagueness. The best software sites shorten the distance from interest to understanding to action: the hero names the job your product does, the first viewport shows the real interface, and proof (logos plus one hard number) lands before the visitor has to think.

Traffic without action is almost always a message problem wearing a design costume. The brief: one singular promise per page, one primary action repeated, proof placed exactly where doubt lives. Shorter pages with a single clear message reliably beat longer ones, so everything that does not serve the promise gets cut.

02 · The site architecture
  1. 01Hero: the job, named

    Headline states the outcome, subline states who it is for, one CTA.

  2. 02Product in the first viewport

    Real interface, moving if possible. A 60 to 90 second product film beats a feature grid.

  3. 03Proof strip

    Logos plus one hard number, immediately after the hero.

  4. 04Three outcome blocks

    What changes for the buyer, not what the software has. Three, never nine.

  5. 05Case proof

    One customer, named, with the before and after in numbers.

  6. 06Pricing, transparent

    Tiers on the page. Hidden pricing filters out the buyers you want.

  7. 07Final CTA, repeated

    Same action as the hero. One conversion verb per site.

Conversion path Hero promise → see the product → believe the proof → check the price → act. Every section either moves that sequence forward or gets cut.

  • Performance: largest contentful paint under 2.5 seconds, layout shift at zero, below-fold media lazy-loaded, modern image formats. Past three seconds the bounce cliff starts.
  • Mobile first: most visits arrive on a phone and mobile-optimised pages convert measurably higher. Design at 390 pixels, then widen.
  • Accessibility: WCAG 2.2 AA. Semantic landmarks, visible focus, 4.5:1 contrast, reduced-motion respected. It is also the cheap route to better speed scores.
  • Motion: one signature idea, executed with restraint. Reveals resolve and hold. Never hijack the scroll.
  • One primary conversion action per page, repeated. Everything else is secondary styling.

CONTEXT
Industry: SaaS & AI. Revenue arrives through self-serve signups: trials and demos, so the product itself must be visible in the first viewport.
The current failure is conversion: visitors arrive and leave. Enforce one singular promise per page, one primary CTA repeated, and place proof directly beside every claim and price.
Scope: the full site. Build the homepage from the sections below, then derive interior pages from the same component system.

PAGE ARCHITECTURE (build in this exact order)
1. Hero: the job, named: Headline states the outcome, subline states who it is for, one CTA.
2. Product in the first viewport: Real interface, moving if possible. A 60 to 90 second product film beats a feature grid.
3. Proof strip: Logos plus one hard number, immediately after the hero.
4. Three outcome blocks: What changes for the buyer, not what the software has. Three, never nine.
5. Case proof: One customer, named, with the before and after in numbers.
6. Pricing, transparent: Tiers on the page. Hidden pricing filters out the buyers you want.
7. Final CTA, repeated: Same action as the hero. One conversion verb per site.

CONVERSION PATH
Hero promise → see the product → believe the proof → check the price → act. Every section either moves that sequence forward or gets cut.

NON-NEGOTIABLE STANDARDS
- Largest contentful paint under 2.5 seconds. Zero layout shift. Lazy-load all below-fold media. Modern image formats (WebP or AVIF).
- Mobile first: design at 390px wide, then scale up. Test every section at that width.
- WCAG 2.2 AA: semantic HTML landmarks, visible focus states, 4.5:1 text contrast minimum, honour prefers-reduced-motion.
- One primary call to action per page, repeated. Do not add secondary CTAs that compete with it.
- Motion: at most one signature animation idea, subtle, resolving into a held state. Never animate on scroll in a way that hijacks scrolling.
- Typography: one display face, one text face, maximum. Real hierarchy through size and weight, not colour.
- No stock-photo cliches, no carousels in the hero, no autoplaying sound.

COPY RULES
- Plain English. Short sentences. Name the buyer and the outcome in the first headline.
- Every claim sits next to its proof. If there is no proof, cut the claim.
- Write placeholder proof slots as [PROOF: description] for me to fill with real numbers and names. Do not invent statistics, testimonials or client names.

DELIVERY
Build it as a fast static site (or the framework of your choice with static output). Show me the homepage first for approval before building further. List any assumptions you made.
04 · The operating plan · how to run it after it ships
01

The Prototyper

Ideates and tests before anything is built properly. Rough pages, quick copy variants, throwaway experiments. Their job is to be wrong fast and cheap so the Builder is right the first time.

Your focus Prototype the homepage and the one money page first. The rest of the site inherits what those two prove.

02

The Builder

Ships the real thing to the standard: the architecture above, the performance budget, the accessibility bar. Takes the winning prototype and makes it production-grade, then stops. Builders who keep building past done create the mess the Sweeper inherits.

Your focus Build from a component system, not page by page. Every page assembles from known blocks so future changes take minutes.

03

The Sweeper

Prunes. Kills the sections nobody scrolls to, the pages nobody visits, the copy that hedges. Most sites fail by addition; the Sweeper is the discipline that keeps the singular message singular.

Your focus Audit quarterly: any page below meaningful traffic gets merged or killed. Fewer, stronger pages rank and convert better.

04

The Grower

Finds product-market fit for the site itself: which messages pull, which channels feed it, which pages earn traffic. Reads the numbers the Builder instrumented, feeds winners back to the Prototyper.

Your focus Map every page to a buyer question and check monthly that each page is winning its question. Gaps become the content plan.

05

The Maintainer

Keeps the ship seaworthy as it scales: dependencies, uptime, performance budgets, broken links, stale proof. Unglamorous, and the reason the site still converts in year three. Every claim on the site has an expiry date; the Maintainer enforces it.

Your focus A standing checklist run monthly: performance budget held, no broken paths, testimonials and numbers still true.

Five archetypes, not five hires. In a small business one person spans all five; the point is knowing which hat is on. Sites rot when the same person builds, grows and prunes in the same sitting without noticing the mode switch.
