The short version
Marketers run on cadence. The campaign launches Friday, the ad creative is approved Tuesday, the landing page needs to ship Wednesday. The engineering team has a sprint backlog and 'one more landing page' is not in it. Most marketers know this dance — and end up either filing a ticket and waiting two weeks, or hand-building a landing page in an old tool that doesn't match the brand.
Website Killer breaks the dependency. You describe the campaign — the offer, the audience, the ad creative, the CTA — and the AI generates a landing page that matches the ad in 10 minutes. Form submissions route to your CRM via webhook. A/B variants happen by cloning the project and pointing different campaigns at each. Custom subdomains per campaign for clean attribution.
The compounding pattern: you build a library of landing-page prompts over time. The first campaign takes 10 minutes; the tenth takes 2 minutes because you've already iterated to the prompt patterns that work for your category.
The job to be done
I have a paid campaign launching Friday. I need a dedicated landing page that matches the ad creative, captures leads, and tracks conversions — without waiting on engineering.
Why other AI builders fall short for this job
- A visual canvas + your engineering team = weeks of dependency
- Most landing-page tools have ugly templates that hurt conversion
- A/B testing usually requires another tool stack
- Your CMS makes every page look the same
- Unbounce / Instapage charge per visitor — punishes successful campaigns

- Self-serve forms wired to your CRM webhook (HubSpot, Salesforce, Customer.io)
- Open Graph + Twitter Card metadata for retargeting traffic
- Clone projects to spin up A/B variants in seconds
- Custom subdomains per campaign for clean attribution
- UTM preservation through form submission
- Sub-1.5s LCP — paid-ads quality score stays high
Where this fits
Real-world scenarios
Friday campaign launch
Ad creative gets approved Tuesday. The landing page needs to match the ad's promise and visual style by Wednesday for QA, Friday for launch. Generate the page Wednesday morning, iterate by Wednesday afternoon, ship Thursday.
Lead-magnet test
You're testing whether a free 'pricing-page audit' lead magnet beats your current 'free demo' offer. Generate both landing pages, split paid traffic 50/50, read the CPL after $500 of spend. Pick the winner, kill the loser.
Webinar registration
A webinar with a partner is happening in 3 weeks. You need a co-branded registration page, a confirmation email, and a calendar reminder flow. Generate the page Monday, wire the form to your webinar tool, ship Tuesday.
Account-based microsite
Sales is running an ABM campaign for 30 named accounts. Each prospect gets a personalized microsite with their logo, named pain point, and a Cal.com booking link. Generate the template once, clone + customize per account, ship in 30 minutes total.
Worked examples
Prompts that work
Three prompts you can adapt for your work. The more concrete the prompt, the less editing afterward.
Paid-ads landing page
Landing page for a Google Ads campaign targeting 'AI website builder'. Audience: non-technical founders comparing tools. Hero: 'Build a working website in 10 minutes — type a prompt, hit generate.' Three feature blocks: AI generation, custom domain, free-forever plan. Form: email only. Thank-you page: 'Check your inbox.' UTM preservation. Posts to HubSpot.
Why this works · Paid-ads prompts include the upstream traffic source. The AI uses it to bias the layout (comparison-shoppers need pricing visibility, brand-search visitors don't).
Lead-magnet page
Lead-magnet page for The B2B SaaS Pricing-Page Conversion Checklist (23-item free PDF). Audience: heads of growth at $1M–$30M ARR SaaS. Hero: '23 things to fix on your pricing page this week.' Form: email only. Preview: page-1 screenshot. FAQ: 4 questions. Posts to ConvertKit.
Why this works · Lead-magnet prompts should name the page count + the audience tier — those filter the right downloaders in.
ABM microsite for a named account
Account-based landing page for {company-name}. Personalized hero: '{company-name}, see how we'd cut your billing-page friction.' Three sections: their specific pain (long form description), our case study with a similar customer, a Cal.com booking link. Style: clean, professional. Form: just 'book a call'.Why this works · ABM microsites convert on personalization. The prompt uses template variables — marketers clone the project and chat-edit the variables per account.

FAQ
Frequently asked questions
Does Website Killer integrate with my CRM?
Forms post to a webhook URL of your choice (HubSpot, Salesforce, Customer.io, Marketo, Pardot, etc.). Native integrations are on the roadmap — for now the webhook covers most stacks. UTM parameters are preserved through form submission for clean attribution.
Can I use my own analytics like GA4, PostHog, or Plausible?
Yes. Drop your tracking snippet in project settings or via a custom HTML embed in the page. Server-side conversion tracking (Meta CAPI, Google Enhanced Conversions) is on the roadmap.
Can I run A/B tests across landing-page variants?
Yes — clone the project to create variants, then split traffic via your ad platform (Google Ads, Meta) using different campaign URLs. Native A/B testing inside Website Killer is on the roadmap; for now the ad-platform-split pattern is what most marketers use.
What about Unbounce / Instapage — is this the same?
Different model. Unbounce / Instapage charge per visitor and per published page, which punishes successful campaigns. Website Killer charges flat per month ($14 Pro, $29 Premium). Output also looks materially better — most marketers who switch don't go back.
Can I use subdomains per campaign for attribution?
Yes — Pro and above support custom subdomains. Most marketers use {campaign-name}.yourbrand.com for paid ads, which gives clean per-campaign attribution in GSC and ad platforms.
How fast can I turn around a landing page when ad creative changes?
Chat-edit. Describe the new headline / image / CTA in the composer and the AI updates the live page. Most marketers update landing pages 2–4 times during a campaign as creative tests develop.
