Website vs Landing Page vs Microsite: What to Use When

The difference between a website and a landing page comes down to purpose, breadth and lifespan. Your website is your permanent digital foundation that serves multiple audiences and goals at once. A landing page is a single page with exactly one goal, usually tied to a campaign. A microsite sits in between: a small, temporary site around one theme, separate from your main site. In this article you get a clear decision framework that weighs the three formats against your goal, your campaign and how long it needs to last, so you don’t needlessly build what you don’t need.

What is the difference between a website, a landing page and a microsite?

In short: a website serves many goals and lasts for years, a landing page serves one goal and lives as long as the campaign runs, and a microsite serves one theme for a defined period.

• Website: your full company site with a homepage, service pages, case studies, an about page and a blog. It has to serve multiple audiences, rank in search engines and last for years. It’s your permanent foundation.
• Landing page: a single page with one message and one action, for example requesting a demo or downloading a whitepaper. Often the endpoint of an ad, an email or a search term. Read in detail how to build one in our guide on the landing page.
• Microsite: a small, standalone site of a few pages around one topic, product or event. Bigger than a landing page, smaller than your main site, and usually temporary.

The distinction isn’t a matter of pretty or ugly, but of function. Anyone who mixes up the three quickly builds too much or sends traffic to the wrong place. And if you’re wondering whether your own site is even still needed, read our take on whether you still need your own website in the AI era.

When do you choose a full website?

You choose a full website when you need a permanent foundation that serves multiple audiences, multiple services and the long term.

Your website is the starting point for almost everything. It has to be findable in Google, build trust with those who see your brand for the first time, and help visitors with very different questions move forward. A prospect typing your name, a customer looking for documentation and a job applicant who wants a feel for your culture all land on the same foundation. That breadth is exactly why a website never converts as sharply as a landing page: it has to do many things at once.

Yet that’s not a weakness, it’s the intention. A well-thought-out website architecture ensures every audience quickly finds the right follow-up page. And because a website lasts for years, it’s the place where you build your SEO, accumulate authority and turn your B2B website into a real lead machine. If you want to understand how all the parts fit together, you’ll find the full overview in our guide to having a B2B website built.

So choose a full website if the basic infrastructure is missing or outdated, if you want to be found structurally, or if multiple audiences must be able to find something with you permanently. If you doubt whether your current site is still enough, run through the 7 signs your B2B website needs replacing.

When do you choose a landing page?

You choose a landing page when you want to steer targeted traffic toward one specific action, away from the noise of your broader site.

The tipping point is almost always a campaign. Are you running ads on a specific search term, sending an email to a defined list, or promoting a single offer? Then you don’t want that traffic on your homepage, because it offers too many choices and distracts. A landing page connects seamlessly to the ad’s promise, repeats one message and asks for one action. That focus is what pushes conversion up.

A few signals that a landing page is the right format:

• You have a paid or targeted traffic source that matches a single message.
• You want to measure the effect and optimize or A/B test the page separately.
• Your offer or audience is too specific for an existing page on your site.

Landing pages live as long as the campaign behind them. You can have many side by side, each for a different segment or ad, while your website stays untouched. Strip away all distraction and make sure the call-to-action is crystal clear: every extra choice costs you leads. In practice, a strong website plus a handful of sharp landing pages already solve most B2B needs.

When do you choose a microsite?

You choose a microsite when one theme, launch or audience is too big for a single page, but doesn’t belong in your permanent site.

Think of a product launch with its own story, a large event, an annual report in web form, or a campaign with its own brand name that deliberately stands apart from your main brand. In those cases you want multiple pages, a distinct look and sometimes a separate domain, without bloating or cluttering your main site.

A microsite does come with a cost that people underestimate. It’s a separate site that you build, host, maintain and eventually have to wind down. It doesn’t automatically share your main domain’s authority, so SEO often starts from scratch. And once the campaign is over, an orphaned site sometimes stays online that no one manages anymore. If you do want to use a separate domain, think ahead about what happens afterward, because a later migration without losing rankings takes extra work.

Often a section or campaign hub within your existing website is a cheaper and more durable alternative: you reuse your domain authority and don’t have to maintain anything twice. Only choose a real microsite when standing apart is a deliberate choice, for example because the brand, the audience or the temporary nature genuinely calls for it.

How do you decide with three questions?

Ask yourself three questions, in this order, and the right format usually falls out on its own.

1. What is the goal? One very specific action for one audience points to a landing page. Multiple goals for multiple audiences point to a website. One defined theme with multiple pages points to a microsite or campaign hub.
2. Is it part of a campaign? Traffic from ads or a targeted mailing belongs on a landing page, not on your broad homepage. Permanent, organic traffic belongs on your website.
3. How long does it need to last? Years and as a foundation: website. As long as the campaign runs: landing page. A defined period around one launch or event: microsite.

A common mistake is building from the format instead of from the goal. People ask for “a microsite” when they actually need a single landing page, or build ten separate pages when their website structure could already do the job. Honestly, the answer in B2B is more often “a better page on your existing site” than “a new site”. So always start with the goal and the lifespan, not with the type.

The short summary

A website is your permanent foundation for multiple audiences and the long term. A landing page is a single page with one goal, tied to a campaign and living as long as that campaign. A microsite is a temporary mini-site around one theme, separate from your main site but bigger than a single page, and only worth it when standing apart is a deliberate choice. Decide with three questions: what is the goal, is it part of a campaign, and how long does it need to last? In most cases a strong website with targeted landing pages is enough.

Not sure which format best serves your goal, or do you want to have your website built or revamped with conversion as the starting point? Plan your free intake and we’ll think along honestly with you, even if the answer is “you don’t need a new site”.
