You need a website if people will look you up. You need a landing page if you are paying to send people somewhere.
Most businesses end up with both, and they do different jobs. The confusion costs money in one direction: companies buy ads and point them at their homepage.
The difference in one table
| Website | Landing page | |
|---|---|---|
| Pages | Many | One |
| Navigation | Yes | Usually none |
| Purpose | Explain the company | Get one action |
| Lifespan | Years | One campaign |
| Traffic | Search, direct, referral | Ads, email, social posts |
| Success measure | Sessions, engagement | Conversion rate |
| Exits | Many | One |
The row that matters is the last one. A website gives a visitor somewhere to wander: pricing, about, blog, careers. That is the point of a website. A landing page removes the wandering, because you paid for that click and you want one specific thing from it.
Why sending ads to your homepage costs you
Your homepage serves everyone. A returning customer looking for the login, a job applicant, an investor, a journalist, and the stranger who clicked your ad. It cannot be sharp for the stranger without failing the others.
Three things go wrong.
Message match breaks. Your ad promised a specific thing. Your homepage talks about the company. The visitor has to translate, and some of them will not.
The action multiplies. Unbounce, working from around 41,000 landing pages, found pages with a single call-to-action link converted at 13.5%, pages with two to four at 11.9%, and pages with five or more at 10.5%. A homepage has a nav bar, which puts you in the last group before you write a word.
You cannot read the result. One homepage receiving traffic from six campaigns tells you your homepage converts at some blended number. It does not tell you which campaign worked.
What a website is for
Keep the website. It does work a landing page cannot.
People who hear about you will search your name and look for evidence you are real. They want an about page, a pricing page, a blog with a recent post, and a way to contact a human. Search engines index it. AI assistants read it when someone asks about your category.
Build it once, on whatever tool suits you. Webflow, Framer, WordPress and Squarespace all do this well, and we have compared several of them.
What a landing page is for
One campaign. One audience. One action.
- A product launch, where the page dies when the launch ends
- An event or webinar, with the date and one registration form
- A lead magnet, gated behind one email field
- A waitlist, before the product exists
- One page per ad set, so each one matches its ad
- One page per client, if you run an agency
Spin it up, send traffic, read the number, and archive it. A landing page is closer to a poster than a building.
The trust problem both share
Ziakis and colleagues surveyed 184 people on what shapes their decisions on a landing page. Trust ranked first among the five dimensions they tested, with user reviews, guarantees and detailed descriptions all scoring above 78%. Personalization ranked last. Their sample was recruited over social media and is a convenience sample, so read it as evidence about what people say rather than what they do.
We measured the other side. Across 675 live B2B SaaS pages we crawled in July 2026, 42.2% showed any social proof at all, and 11.6% placed it before the first call to action. So most of these pages ask a stranger to act before giving them a reason to believe.
Whichever you are building, that gap is the cheapest thing to fix.
How to decide today
Answer one question: are you about to spend money driving traffic somewhere?
If yes, build the landing page first. It is one page, it can be live this afternoon, and it will tell you whether the offer works before you invest in a full site.
If no, and people are finding you by searching your name, build the website.
If you are doing both, keep them separate. Your site stays where it is. Each campaign gets its own page, and each page reports its own number.
