How to build a landing page for your ads? We analyzed every ad-specific landing page YC companies run
Most companies point paid traffic at their homepage. In the whole Y Combinator portfolio, only 3.6% of ad clicks land on a page built for the ad. We rendered every one of those pages. Here's the playbook they share, and how it changes by business type.
To build a landing page for an ad, send the click to a page made for that one ad instead of your homepage: repeat the ad's promise in the headline, strip the site navigation so there is nothing to click away to, and offer a single clear action. That is the whole idea, and it is backed by real evidence. But almost nobody does it.
We know this because we just measured it. In our study of how all 6,055 Y Combinator companies advertise, we captured the destination of 78,348 live ads. Then we followed the links. Here is where the clicks actually go:
Two in five ad clicks hit a homepage. Another third land on a generic product page. The pink bar, the page that was actually built for the ad, is 3.6%. In the entire portfolio, only 69 companies run ads to a dedicated landing page, across 187 distinct pages. This article is about what those 69 do differently, because they include Gusto, Stripe, Brex, Ironclad and Rippling, and they are not doing it by accident.
The short version
- A landing page is the homepage with every exit removed. The custom pages carry a median of one nav link and six footer links, against roughly eight and thirty on the same company's homepage.
- Match the ad's promise in the headline. The strongest independent evidence for why landing pages work is message match: the page repeating what the ad said.
- One page, one action. Pick "start free" or "book a demo", not both as equals. Only about a third of YC custom pages gate on a demo; most lead self-serve.
- Build for your business type. B2B and fintech pages carry forms and demos; consumer and health pages run quizzes and offers; education pages are pure lead capture.
- Build few, and keep them alive. Most companies that build a custom page build exactly one. 13% of the pages we found already 404 while their ads keep spending.
Almost nobody builds one, and that's the opportunity
Sending paid traffic to your homepage feels safe. It is your best page, the one you polish most. But a homepage has a different job: it is built to let a stranger explore everything you do and pick their own path. An ad already did the picking. Someone clicked because a specific promise caught them, and the homepage makes them find that promise again among ten other things.
The benchmark data says this costs you. Unbounce, measuring purpose-built landing pages, reports a median conversion rate of 6.6%, with SaaS lowest at 3.8%.¹ WordStream, measuring the pages advertisers actually point Google Ads at (mostly homepages and product pages), reports a median of 2.35%.² Those two numbers use different samples and definitions, so the gap is not a clean "landing pages convert 3x better". But every credible source points the same direction: a focused, ad-matched page beats a general-purpose one for campaign traffic.
The honest caveat, which most articles skip: nearly every specific lift number in this field comes from a company that sells landing-page software, and advertisers who bother to build pages also tend to run tighter campaigns. So the benchmarks cannot fully separate the page from the team. What holds up independently is not the headline percentage, it is the mechanism. That is the part worth copying.
What a real landing page is: the homepage with the exits removed
Here is the whole idea in one company. Gusto sells payroll. Its ad sells payroll. Its custom landing page sells payroll and nothing else. Its homepage sells the entire company. Same brand, three very different levels of focus.
The single most reliable signature of a purpose-built page is a stripped navigation bar. A homepage wants you to wander; a landing page wants you to stay. When we compared each custom page to the same company's homepage, the difference was stark and consistent.
This is not decoration. It maps onto real evidence. HubSpot A/B tested five of its own highest-traffic pages with and without navigation, and removing it lifted conversion 16 to 28% on mid-funnel pages.⁴ The closer someone is to converting, the more an exit link costs you. The custom pages in our data are doing exactly this on purpose.
The five-step playbook
Strip away the industry differences and every good ad landing page does the same five things. This is the part to copy directly.
- Match the ad's promise in the headline. If the ad said "Free pentest, pay if critical", the page opens with that, not with your generic tagline. Message match is the most-cited driver of landing-page performance, and it is grounded in real theory (information scent, from Pirolli and Card). The strongest independent evidence is Ghose and Yang's econometric study in Management Science: higher landing-page quality tracks both higher conversion and lower cost per click.³
- Strip the navigation. Keep the logo, drop the menu. Give people one path forward and no path sideways. 77% of the YC custom pages do this.
- Offer one primary action. Unbounce's analysis of 18,639 pages found a single call to action converts higher (13.5%) than pages with two or three (11.9% and 10.5%).⁵ Pick your one action and repeat it; don't dilute it.
- Make it fast, especially on mobile. The best-designed study in the space, Google and Deloitte's "Milliseconds Make Millions", analyzed 30 million-plus mobile sessions and found a 0.1-second load improvement lifted retail conversions by 8.4%.⁶ A one-purpose page is simply easier to keep fast than a template-heavy homepage. Most ad traffic is mobile, so this is where the money is.
- Keep it short, and set form length by intent. The rare vendor-independent field experiment here, Gafni and Dvir's test on 27,083 randomized visitors, found a short 42-word page beat a long 278-word one decisively (42% versus 29% conversion).⁷ Fewer choices, more conversions. If you need a form, its length should match the ask, not a universal "three fields" rule.
There is a sixth reason that has nothing to do with conversion rate, and it is under-appreciated: a better landing page lowers your cost per click. Google confirms that landing-page experience feeds Quality Score, which affects how much you pay at auction.⁸ So a dedicated page can pay for itself on the media side even if it never moves your conversion rate.
Don't build a page per keyword. Build a page per promise. If two ads make the same promise to the same audience, they can share a page. If they make different promises, splitting them is what message match means in practice.
Build it for your business type
The playbook is universal; the shape of the page is not. The single biggest predictor of what a YC landing page looks like is what the company sells. Here is how the 155 pages we could render break down, and the pattern inside each segment is remarkably consistent.
| Business type | Pages | Uses "book a demo" | Has a form | Strips nav | Dominant shape |
|---|---|---|---|---|---|
| B2B / SaaS | 91 | 42% | 58% | 42% | Demo request or free trial |
| Fintech | 22 | 41% | 68% | 41% | Application form, trust-heavy |
| Healthcare | 17 | 12% | 6% | 0% | Eligibility quiz |
| Consumer / ecommerce | 12 | 8% | 33% | 50% | Offer or first-purchase |
| Education | 9 | 0% | 100% | 89% | Course lead capture |
B2B and SaaS is the biggest group and the most mixed. Ironclad runs the textbook demo page: the headline is literally "Schedule Your Contract Management Demo", the navigation is stripped to nothing, one email field, one "Request Demo" button, then G2 badges, named testimonials and an FAQ. Nothing else.
But the demo page is not the default even in B2B. CodeAnt AI, a code-security startup, matched its "Free pentest, pay if critical" ad with a page that opens on "Find the breach before the attacker does" and ends on "pricing your CFO will actually approve". Self-serve, priced, no sales gate. Both are B2B; they made opposite calls about how the product is bought.
Fintech looks like B2B but carries more form (68%) and more trust signals, because the ask is an account or an application, and the buyer needs to feel safe. Brex and Alaan both cut their whole platform down to a single product on the ad page (a card, a business account) rather than pitching the suite.
Healthcare breaks the mold entirely: 12% demos, 6% forms, and 0% keep a normal nav. These are consumer-health companies, and the dominant shape is the eligibility quiz. Probably Genetic turns its ad question ("Autism and cognitive delays. One genetic explanation?") straight into the page headline and a "See if my child qualifies" button. The quiz is the conversion mechanism; the form comes later, once you're invested.
Consumer and ecommerce lean self-serve (67% of consumer pages) and revolve around a first purchase or an offer: Tovala's "Dinner is handled", Inito's "$40 off your first order". Note the ecommerce nuance, because it cuts against the whole article: when you already have a conversion-optimized product page (reviews, images, cart, trust badges) and the ad is for a specific product, that product page is often the right destination, and a separate landing page just adds a step. The "always build a landing page" rule has real exceptions, and optimized ecommerce is the main one.
Education is the purest lead-capture segment: 100% of the pages carry a form, 89% strip the nav. AgendaPro builds a separate page per vertical (one for psychology clinics, one for medical clinics, one for salons), each in the local language, each a single free-trial form. That is message match taken to its logical end: a different page for each audience the ads target.
Should it say "book a demo"?
This is the question I get most, and the assumption is usually that a B2B page should funnel to a sales call. The data says otherwise. Across all the YC custom pages, only 34% offer a "book a demo" or "talk to sales" path at all. Roughly two thirds lead with self-serve: "start free", "sign up", "get started".
The rule is simple: match the CTA to how your product is actually bought. If someone can get value alone, let them start alone, and put "start free" as the primary action. If buying genuinely requires a conversation (an annual contract, a security review, five stakeholders), a demo CTA is honest and a form is worth it. The mistake is defaulting to "book a demo" because it feels enterprise, when your product is something a person could just try. We wrote a whole piece on choosing between a free trial and a demo, and the short version is that the best pages often offer both: a primary "start free" with a quiet "talk to sales" for the buyers who want hand-holding. If you do run demos, keep an eye on what each one actually costs you before you make it the only door.
Defaulting to "book a demo" because it feels enterprise, when your product is something a person could just try, is the most common self-inflicted wound on a B2B landing page.
What goes in the footer
The footer question has a clean answer: put almost nothing there. A homepage footer is a wall of exits, 30 to 50 links across product, company and resources columns, plus social icons and a newsletter box. The whole point of a landing page is to remove exits, so the footer is the first place to cut.
The YC custom pages cut it to a median of six links. Usually that is just a privacy policy (present on 59% of pages), terms (57%), and a copyright line. Social links survive on only 45%, and the "Backed by Y Combinator" badge, so common on YC homepages, appears in just 6% of these footers. Once a company is spending real money on ads, the YC halo comes off the growth page. Keep the legal links you actually need, drop the sitemap, the careers link, the social icons and the newsletter signup. None of them help the one action you want.
The mistakes to avoid
Two failure modes showed up again and again in the data, and both are avoidable.
The first is building too many pages. More than half the companies that build a custom page build exactly one. The "500 landing pages for 500 keywords" approach that some guides push creates a maintenance burden nobody keeps up with, which leads straight to the second mistake.
The second is letting pages die while the ads run. Of the 187 custom pages we found, 25 (13%) already return a 404. The ad is live, the budget is spending, and the page it points to is gone. Ironclad has ads pointing at expired analyst-report pages; CodeAnt has four dead paths. A landing page exists for a campaign, campaigns end, but the ads keep running unless someone turns them off. If you build a page for a campaign, put a reminder to take the ad down when the campaign ends. It is the cheapest fix on this list and the most ignored.
The uncomfortable read of this whole study: most YC companies, even ones spending heavily, skip all of this and point paid traffic at a homepage. The 69 who don't are the ones who decided the click was worth a page. That decision, more than the design, is the edge.
Frequently asked questions
Should ads go to a landing page or the homepage?
For any campaign with specific intent (paid social, non-branded search, a named offer), send the click to a dedicated landing page, not the homepage. A homepage is built to let people explore your whole company; an ad already made a specific promise, and the page should keep that one promise and remove everything else. The exceptions are branded search, where someone already knows you, and ecommerce product ads, where an optimized product page with reviews and a cart is usually the better destination than a separate page.
What makes a good landing page for ads?
Four things, in order: the headline restates the promise the ad made (message match), the site navigation is stripped so there is nothing to click away to, there is one primary action instead of three competing ones, and the page loads fast on mobile because most ad traffic is mobile. Everything else (social proof, a short form, pricing) supports those four. Across the YC companies that build dedicated pages, 77% strip the navigation and 74% lead with a single clear headline.
Should a B2B landing page say "book a demo" or "start free"?
It depends on how your product is bought, and the honest answer from the data is that most do not gate on a demo. Only about a third of the YC custom pages offer a "book a demo" or "talk to sales" path; roughly two thirds lead with self-serve ("start free", "sign up", "get started"). Use a demo CTA when the product genuinely needs a sales conversation to buy, an annual contract or a multi-stakeholder deal. Use self-serve when someone can get value alone. Many strong pages offer both: a primary "start free" with a secondary "talk to sales" for the buyers who want it.
How many landing pages do I need?
Fewer than the marketing blogs suggest. Build one page per distinct promise or audience, not one per keyword. More than half of the YC companies that build dedicated pages run exactly one. The "500 pages for 500 keywords" approach creates a maintenance burden that ends in dead links: 13% of the YC custom pages we found already return a 404 while their ads are still running and spending. Ten pages you maintain beat fifty you forget.
Do dedicated landing pages actually increase conversion rates?
Usually yes for campaign traffic, but the direction of the effect is far better supported than the specific numbers. Nearly every "landing pages convert 3x better" statistic comes from a company that sells landing-page software, and advertisers who build pages also tend to run tighter campaigns, so benchmarks cannot cleanly separate the page from the team. What holds up independently is the mechanisms: message match, removed navigation, a single call to action, and page speed all have real evidence behind them. Treat every round-number lift claim as directional, and A/B test the page against your current destination before you scale spend.
What should the footer of an ad landing page include?
Almost nothing. A homepage footer carries 30 to 50 links across product, company and resources columns; a good ad landing page cuts that to a median of about six, usually just a privacy policy, terms, and a copyright line. The point of a landing page is to remove exits, and the footer is a wall of exits. Keep the legal links you need (privacy and terms), drop the full sitemap, the careers links, the social icons and the newsletter box. Among YC startups, only 6% keep a "Backed by Y Combinator" badge on these pages.
