Every AI landing page builder demo looks incredible. Then you point a Google Ads campaign at one and the leads go nowhere.
I know because I tested it this morning. In April we moved Flock, a UK hen party planner, off Wix with Claude Code in 5 days: 794 messages, 87 deploys, 130 pages. So today I gave Claude Code one real ad brief for Flock, four different ways, and measured every page it built.
Three of the four quote forms sent the lead nowhere. None fired a conversion. One put the form eight phone screens down. The fourth run fixed all of it in 86 seconds, and the only change was a 26-line file.
Below is that test, the 11 builders I would look at for a paid page (priced on 10 October 2026), and the brief to copy.
👉 The short version
The builder matters less than the brief. Claude Code built the best page of the lot, but only once I told it where the form goes, where the lead is sent and which conversion fires.
If you can’t write that brief, Lovable or Framer get you a live page fastest. If you need A/B tests, Unbounce or Swipe Pages. If you already have a page that’s losing paid clicks, start with an audit. The rebuild can wait.
The 11 builders, in the order I would try them for a paid page:
- Claude Code, from £18 a month, the best page if you write the brief
- Postclick, your first page free, audits it then builds the fix
- Lovable, free to start, Pro £22, prompt to a live page
- Framer, free to start, Basic £8, the best-looking pages
- Unbounce, from $29, A/B testing from $149
- Swipe Pages, from $29 billed yearly, fast pages for ads
- Leadpages, from $29, publishes from Claude or ChatGPT
- v0, free to start, Plus $30, for a team on Vercel
- Bolt, free to start, Pro $25
- Base44, from $16 billed yearly, in the only AI vs human test I found
- Landingsite, Durable and Mixo, from $10, a whole small-business site in a minute
And the 3 mistakes: a form wired to nothing, proof the AI made up, and a portfolio page with the form at the bottom.
The test: one ad, four prompts
The ad was real-shaped. Keyword “bath hen party”, headline “Bath Hen Party Weekends | Planned For You”, goal: the visitor asks for a quote. I ran each prompt in a fresh Claude Code session on Opus and changed only what the session was given.
- One line. Just the brief.
- Plus a design skill. The same brief, with Anthropic’s frontend-design skill switched on.
- Plus the real business. Flock’s facts, its brand colours and fonts, and six real photos from its Bath page, with “do not invent prices, reviews or numbers”.
- Plus a page contract. Everything in run 3, plus a 26-line CLAUDE.md that says where the form goes, where it posts, and which conversion fires.
Then I opened every page at 1440 px and 390 px and measured it.
| Run | Build time | Real photos | Invented claims | Form posts the lead | Conversion tag | Form on a phone |
|---|---|---|---|---|---|---|
| 1. One line | 73 sec | 0 | None, and no offer either | No | No | Starts on screen 1 |
| 2. Design skill | 163 sec | 0 | ”No payment now” | No | No | Starts on screen 1 |
| 3. Real business | 101 sec | 6 | None | No | No | Screen 8 |
| 4. Page contract | 86 sec | 6 | None | Yes | Yes, with the gclid | Screen 1 |
Runs 1 and 2 built the same skeleton in different clothes: form in the hero, why Bath, how it works in three steps, an FAQ and a dark call to action at the end. Run 2 looked better and took more than twice as long, and it made up a payment policy Flock doesn’t have. Flock takes a £50 deposit per guest.
Run 3 was the nicest page and the worst landing page. More on that below.
Run 4 is the one I would put money behind. Same facts, same photos, and the form is on the first phone screen with four fields. It posts to the endpoint, keeps the gclid from the ad click and fires the Google Ads conversion before it sends. The only claim on it is the real £50.
1. Claude Code, what we rebuilt Flock with
Claude Code comes with every paid Claude plan. Pro was £18 a month on the UK page today, or £15 billed yearly, and Max starts at £90. It shares your plan’s usage, so a big build eats the same allowance as your chats.
It’s not a page builder. It’s an engineer in your terminal that will build a page, a site or the tracking behind both. That is why it won my test, and also why run 3 went wrong: it builds what you describe, and “a landing page” to a model mostly means a portfolio.
Flock is the proof it works at full size. We moved 130 pages and 128 Wix URLs, migrated 156 images in a single prompt, and wired the full tracking stack: Google Ads with the gclid, GTM, Notion and a Gmail alert. The old Wix homepage had one button and no tracking. The new one asks for a quote twice on the first screen.
The whole build, with every before and after, is on the Flock case study page.
Pick it if you or someone on your team will write a proper brief and read what comes back. Skip it if you want to click around a visual editor.
2. Postclick, for the page you already pay for
I built this one, so weigh this section accordingly.
Most people searching for an AI landing page builder already have a page. It’s just losing paid clicks. Rebuilding from a blank prompt throws away the one thing you know, which is how that page performs.
Postclick starts from your current page instead. It audits the page your ads send people to and ranks every leak by what it costs. Then it designs two better versions in your brand and builds the one you pick as a complete HTML page you own and can host anywhere, including on any builder on this list.
An audit is 18 credits, two designs 20 and a build 60. The free plan is 98 credits for 30 days, which covers one page all the way: the audit, two designs and the build. Paid plans are $9, $29 and $99 a month.
The audit runs on what I learned reading 2,201 landing pages by hand across 54 industries, every one behind a real Google Ads campaign.
Pick it if you have a live page and want to know what to change before you rebuild. Skip it if you are starting a brand-new offer with no page yet.
3. Lovable, the fastest prompt-to-live page
Lovable is free to start with no card. Pro was £22 a month for 100 credits, with custom domains and the Lovable badge removed. Business is £44.
You describe the page, it builds it, and it’s live on a URL in minutes. For someone who has never opened a terminal, this is the closest thing to Claude Code’s result without the setup.
Give it the same page contract as run 4 below. Lovable builds what you describe as well, so if you don’t name the form endpoint and the conversion event, nobody will.
4. Framer, for a page that has to look designed
Framer is free to start with 500 AI credits. Basic was £8 a month billed yearly on the UK page, with a custom domain.
Framer’s AI gives you a first draft, then you’re in a proper design canvas. Of everything here it’s the one where a designer won’t wince. It’s built for sites more than ad pages, so check the form and the tracking yourself before you spend.
5. Unbounce, when you need A/B tests
Unbounce starts at $29 a month, or $22 billed yearly. A/B testing starts on Experiment at $149, or $112 billed yearly.
It’s the most capable builder made for paid traffic, and the AI is a helper inside it rather than the whole product. Before you pay for testing, check your traffic can finish a test: I worked through the sum in the CRO tools post, and at $10,000 a month a small change takes about seven months to prove.
6. Swipe Pages, the cheapest builder made for ads
Swipe Pages was $29 a month billed yearly for Startup, $69 for Marketer and $149 for Agency. It’s built for fast mobile pages behind ads, and it’s what I’d pick on a tight budget when the page needs to be in a builder a client can edit.
7. Leadpages, publish straight from Claude or ChatGPT
Leadpages says plans start at $29 a month, with testing from $99. The UK cards showed Pro at £25 and Grow at £85.
The interesting part is on Pro: an MCP connector and “Publish from Claude / ChatGPT”. So you can write the page with Claude and push it straight into a builder that hosts it and collects the leads. Grow adds manual A/B tests and dynamic text replacement, which swaps the headline to match the search.
8. v0, if your developer lives on Vercel
v0 is free with $5 of one-time credits and 7 messages a day. Plus is $30 per user a month. It writes React and deploys to Vercel, and the home page now lets you sign in with your ChatGPT plan. If your developer already runs your site on Vercel, a v0 page slots straight in.
9. Bolt, the cheapest way to try prompting a page
Bolt is free for 1 million tokens a month, with Bolt branding on the site. Pro is $25 a month from 10 million tokens, with a custom domain and no branding. It’s a cheap way to see what prompting a page feels like before you commit to anything.
10. Base44, the one in the only A/B test I found
Base44 starts at $16 a month billed yearly for 100 message credits. Builder is $40.
It’s here because of Crazy Egg’s test. Claude wrote the brief and copy, Base44 built the page, and it beat their human-designed page 80.65% to 55.68% on signups, a 44.83% lift at 99% confidence.
Read the small print before you quote it, though. Just under 55,000 people per variant entered the test, but only 176 reached the human page and 124 reached the AI one. That’s a real result on about 300 visitors, and Crazy Egg says the sample is small itself. It’s a good reason to test an AI page, not proof one will win.
11. Landingsite, Durable and Mixo, a one-page site in a minute
These three build a whole small-business website from a couple of answers. Landingsite is $10 a month per website billed yearly for one page. Durable is free to start and $22 a month for Launch. Mixo is free with its badge and $20 a month for a business site.
They suit a plumber or a café that needs to exist online by tonight. For a paid campaign they’re the wrong shape: you get a site, not one page built around one ad, and you can’t see much of what happens after the click.
What builders are showing off on X
The most impressive AI landing pages right now are on X, and they’re worth a look before you pick a tool.
Peter Wang built a Claude Code skill on Higgsfield that turns a prompt into a scrolling 3D world. The post says the three sites in the video were one-shot results at about $10-15 each. 3,800 people liked it.
Erfan spent 45 minutes with Claude Code on a fintech site with micro-interactions, no Figma and no custom JavaScript. Look at the badge above the headline, though: “Trusted by 80M+ Users”, on a brand that is a demo. That’s mistake two below, in a demo built to impress.
The people who build pages for clients are less excited. A developer on Hacker News tested the circulating prompt and skill setups for client work, and put it bluntly: “changing anything afterwards is brutal”. Another said the blue and purple gradients make them close the tab.
Both are right for a paid page. A demo is judged on the first scroll. Your page is judged on the form, the week after, by someone who clicked an ad.
3 mistakes that waste the click
1. A form wired to nothing
All three of my first runs built a quote form with no action, no endpoint and no conversion tag. They looked finished. Every lead would have vanished, and Google Ads would have learned that the campaign converts at zero.
Before a single click goes to an AI-built page, submit the form yourself and check the lead arrives and the conversion fires. Here’s how I check conversion tracking. The fix is to name the endpoint and the tag in the brief, which is what run 4 did.
2. Proof the AI made up
Run 2 invented “No payment now. You only book if you like the plan.” Erfan’s demo invented 80 million users. Give a model no facts and it fills the gap with plausible ones, and a buyer who catches one stops believing the rest.
The look can give it away too. Anthropic’s own frontend-design skill lists a cream background with a serif headline and a terracotta accent as a tell of a generated page. Run 2, with that skill on, came out cream and serif anyway.
3. A portfolio page with the form at the bottom
This is the one that surprised me. Run 3 had the real facts, the real photos and the right brand, and it was the best-looking page. Then I cut it into phone screens.
The form started 6,361 pixels down, on screen 8 of 10. There was a quote button at the top, but the form itself sat below a gallery, an activity list and a story. Most paid visitors on a phone never get that far.
Elevarus, a paid traffic agency, describes the same thing: give Claude a beautiful landing page brief and it builds a portfolio. Their fix is a page contract in CLAUDE.md, and it’s the one I used for run 4.
The page contract to paste into Claude Code
Save this as CLAUDE.md in the folder where Claude Code builds the page. Fill in the blanks. It’s the 26-line file from run 4 with Flock’s details taken out.
CLAUDE.md for a paid landing page. Fill in the blanks
# Page contract: ________ landing page
This page exists to turn one ad click into one ________ (quote / call / signup).
## The ad
- Keyword: ________
- Ad headline: ________
- The H1 repeats the ad's promise in plain words, using the keyword.
## The offer
- Only what is in facts.md: the price, the terms, what is included.
- Do not invent prices, reviews, star ratings, customer counts, guarantees or "free".
## The one action
- The form itself starts on the first screen on a 390 px phone and on desktop.
- ___ fields at most before the button: ________
- The form POSTs to ________ (action and method set in the HTML).
- A hidden field named gclid is filled from the ?gclid= URL parameter.
- Load gtag.js for AW-________. On submit, fire the conversion
('AW-________/________') before the post.
## The proof
- Use the real photos in images/. Only claims from facts.md.
## The shape
- 5 sections at most below the hero.
- Use brand.css for colours and fonts. No navigation links that leave the page. Then put three things next to it: facts.md with your real offer, brand.css with your real colours and fonts, and an images folder with real photos. In my test those three moved the page from a template to a real business. The contract moved it from a nice page to one that collects leads.

Prices are what each pricing page showed me from the UK on 10 October 2026, so a few are in pounds. They change often, so check before you buy.
If you’d rather compare builders on what your clicks need instead of what the AI does, the best landing page builder for Google Ads prices seven of them that way.

- What is the best AI landing page builder?
- For a page behind paid ads, Claude Code built the best page in my test of four prompts on 10 October 2026, but only once the brief named the form, its endpoint and the conversion tag. Without that, three of four pages sent the lead nowhere. If you won't write a brief, Lovable or Framer get you a live page fastest, and Unbounce or Swipe Pages are the builders made for ads.
- Can AI make me a landing page?
- Yes, in about one to three minutes. My four Claude Code runs took 73, 163, 101 and 86 seconds. The page is the easy part. Check three things before you send paid traffic: the form posts the lead somewhere real, the conversion tag fires, and the form is on the first phone screen.
- Can ChatGPT build a landing page?
- It can write one, and two builders now connect to it directly. Leadpages' Pro plan lists Publish from Claude / ChatGPT through an MCP connector, and v0 lets you sign in with your ChatGPT plan. For a full build with tracking, a coding agent such as Claude Code does more, because it can edit the files and wire the form.
- Is there a free AI landing page builder?
- Several start free: Lovable, Framer, Bolt (1 million tokens a month), v0 ($5 of one-time credits), Durable and Mixo. Postclick gives 98 free credits for 30 days, enough to audit, design and build one page. Free plans usually carry the builder's branding and no custom domain.
- Do AI landing pages convert better than human ones?
- The only public test I found is Crazy Egg's: a Claude-written, Base44-built page beat their human page 80.65% to 55.68% on signups, a 44.83% lift at 99% confidence. But only 124 and 176 visitors reached the two pages, so treat it as a reason to test an AI page, not proof it will win.
- Why does my AI landing page have fake reviews?
- Because the model had no real ones. In my test, the run with no facts invented a payment policy, and a popular Claude Code demo on X shows Trusted by 80M+ Users on a demo brand. Give the model a facts file and tell it not to invent prices, reviews, ratings or customer counts.
