The short version
An agency website is a sales tool, full stop. Prospects land from an inbound email, an outbound LinkedIn message, or a referral; they spend 90 seconds deciding whether to take the discovery call. The site has to do three jobs in those 90 seconds: prove the work is good (case studies with metrics), prove the agency ships (recent dates, real client logos), and route the prospect to a discovery call (one CTA, repeated).
Most agency sites fail at the first job. They show a wall of logos with no case studies, or case studies without metrics, or metrics so vague ('increased engagement') they read as marketing-speak. A great agency site shows 5–7 case studies with named clients, named outcomes, and named metrics — and that's it.
Website Killer generates the agency site from a prompt that names the work. You describe 5 case studies (client name, problem solved, deliverable, metric, year) and the AI generates the layout with each one rendered as a scrollable case-study card or, optionally, its own /case-studies/[slug] page. Add the services you offer, the team, the contact flow — and the site is ready to send to a prospect this afternoon.
The problem
Pitching new clients with an outdated agency site costs you the deal in the first 5 seconds. Ship a new one this afternoon.
Website Killer for agency website
What you get out of the box
- Bold hero with services pitch (one of 12 agency-grade design systems)

- Services grid with deliverable + timeline + price-band per service
- Team section (optional) with photos, roles, and brief bios
- Testimonials with structured data (Review schema where applicable)

- Source-code export so you can hand off the codebase or host it yourself
- Per-month pricing instead of per-site fees (Pro $14/mo for 5 sites)
What great looks like
Agency sites that win pitches share five traits. Every one of them is a deliberate choice, not a template default.
- Case studies with named clients and named metrics — 'For Linear: redesigned the changelog, 34% increase in newsletter signups'
- A point of view in the hero — 'We build the marketing site engineering hates building' beats 'A full-service digital agency'
- Pricing transparency in services — even price bands ('Marketing sites start at $25K') reduce sales friction by half
- Team page with real people — agency buyers buy people, not brand; faces convert
- A recent case study — anything older than 12 months reads as 'they stopped winning work'
Worked examples
Prompts that work
Three real prompts you can adapt. The more concrete the prompt, the less editing you do after.
Boutique design agency
Website for Field Studio, a 4-person product design agency in Portland that builds marketing sites and brand systems for SaaS companies. Hero: 'We build the marketing site your engineering team hates building.' Five case studies: (1) Linear — redesigned the changelog, 34% increase in newsletter signups; (2) Vercel Ship — full conference site in 3 weeks; (3) Resend — pricing page rebuild, 22% increase in self-serve conversion; (4) Cal.com — full marketing redesign, brand system; (5) Default — series-A pre-launch site. Services: marketing sites, brand systems, conversion audits. Pricing bands: marketing site $25K–$60K, brand system $40K–$80K. Team: 4 people, photos + brief bios. CTA: book a 30-minute project call.
Why this works · Boutique agencies convert on case-study clarity. The prompt names every client, problem, and metric so the AI features them as data points.
Performance marketing agency
Website for Cardinal, a performance marketing agency for DTC e-commerce brands ($1M–$30M ARR). Hero: 'We turn ad spend into profitable growth.' Services: paid social, paid search, lifecycle, CRO. Five case studies: a skincare brand (3.2x ROAS in 90 days), a coffee subscription (cut CAC 38%), a footwear brand (scaled paid spend from $40K/mo to $400K/mo profitably), a CPG launch (sold out in 4 weeks), a wellness brand (lifecycle revenue 4x). Team: 8 people. CTA: book a free 30-min audit.
Why this works · Performance marketing agencies convert on ROAS / CAC / CPA metrics. The prompt foregrounds the numbers because that's what the buyer is comparing on.
Dev shop / engineering agency
Website for Twinscroll, an engineering shop that builds custom internal tools and dashboards for series-A through series-C SaaS companies. Hero: 'We build the internal tools your eng team can't get to.' Five case studies: a fintech ops dashboard (cut weekly ops time 60%), a healthcare CRM (replaced 3 legacy tools), a multi-tenant admin panel for a vertical SaaS, a logistics scheduling tool, an HR onboarding portal. Stack: Next.js, Postgres, Prisma, Vercel. Services: internal tools, dashboards, integrations, technical due diligence. Pricing: $30K–$200K per project. CTA: scope a project.
Why this works · Dev shops convert on technical credibility. The prompt asks the AI to include the stack on the home page — engineering buyers want to know what you ship in before the call.
Avoid these
Common mistakes
- Case studies without metrics — 'we built a website for X' is invisible; '38% increase in self-serve signups' is bookable
- Wall of logos with no context — 30 client logos in a row reads as 'they did some unspecified work for these companies'
- No pricing or price bands — discovery calls eat hours; a $25K–$60K band filters the 60% who can't afford you
- Stale case studies — anything older than 18 months reads as 'they stopped winning notable work'
- Hidden 'book a call' CTA — agency sites convert on the call booking, every section should route to it

FAQ
Frequently asked questions
Can my agency white-label sites built with Website Killer?
Yes — projects export to clean source code, so you can hand off the codebase to your client or host it on your own infrastructure (Vercel, Netlify, your own VPS). The client never sees a Website Killer login or branding.
Does the Business plan support multiple client projects?
Business gives you 10 projects and 10 domain slots. For agencies running more than 10 active client sites at once, reach out to sales@killerwebsite.ai for a custom plan — most multi-client agencies sit at 5–8 active projects after factoring deliveries and hand-offs.
Can I generate a site in the discovery call to show, not pitch?
Yes — this is the agency-specific power move. Start the call with your standard discovery questions, then generate the client's site in the prompt composer during the conversation. The 10-minute generation turns a 'we'll send a proposal' deal into a 'when can we start' deal.
How do I handle the client hand-off — do they get a login to Website Killer?
You have two options. Option A: export the code and host it on the client's infrastructure — they own the deliverable, you walk away. Option B: keep the project on your Website Killer account and bill the client monthly for ongoing edits — the agency model most retention-focused shops prefer.
Can I bring my own design system or brand tokens?
Right now Website Killer applies one of its 52 tuned design systems per project, picked from your prompt. You can override colors, typography, and spacing via chat-edit. For agencies with strict brand systems per client, exporting and customizing the code is the path — the export is clean enough to drop tokens into.
What's the typical agency workflow with Website Killer?
Most agencies use it like this: (1) discovery call, capture the brief; (2) generate the site live in the chat composer; (3) iterate via chat-edit with the client present or async; (4) deliver via export or by transferring the project to the client's domain; (5) invoice for the work, optionally retain the project for ongoing edits. End-to-end delivery is days, not weeks.
Can my testimonials show up as star ratings in Google?
Yes — Review schema is supported. Per Google's policy, the review must be from a real customer of a service or business (not 'reviews of the agency by the agency owner'). For real agency case studies with named clients, Review schema applies cleanly and yields rich-result stars.
