What is a landing page? When you need one and what it costs
Written by Temei · Updated · 5 min read
TL;DR
- A landing page is one page that serves exactly one action: leave your details, sign up, or buy now. Everything on the page exists to lead to that action.
- A website serves several audiences and several purposes at once. A landing page removes every side path, including the navigation menu, so there is only one way forward.
- At Temei a landing page starts from 1,888,000₫ and is delivered in 3–5 business days once the copy and images are in.
The one-sentence definition
A landing page is a destination page built for a single objective, tied to one specific traffic source, and measured by the share of visitors who take the action you asked for.
The word "destination" is where people get confused. A landing page is not just any page someone happens to arrive on; it is a page you deliberately build as the end point of a known traffic source — an ad, a message, a QR code on a flyer. Because you know where the visitor came from, the copy can speak directly to the thing they were just interested in.
How a landing page differs from a website
| Landing page | Website | |
|---|---|---|
| Goal | One action | Several: profile, hiring, news, contact |
| Navigation | No menu, to avoid distraction | Full menu so visitors can explore |
| Audience | One specific campaign segment | Many different groups |
| Lifespan | Lives with the campaign, rewritten when the message changes | Long-lived, updated gradually |
| How it is measured | Completion rate of the target action | Many metrics, page by page |
The two neither replace nor exclude each other: the website is your authoritative place to look things up, the landing page is the destination of one specific campaign.
The five parts it must have
A headline that matches what the visitor just clicked. If the ad promised "interior design for small apartments", the page headline has to repeat that idea. Put the ad headline next to the page headline and read both: if they do not say the same thing, you are asking the visitor to bridge the gap themselves, after you have already paid for the click.
A concrete offer. "Contact us" is a wish, not an offer. "Get a quote based on your apartment size within 24 hours" is concrete: the visitor knows what they get, in what form, and when.
Evidence. Real product photos, your working process, a list of what gets delivered, an FAQ. If you do not have customer reviews yet, do not invent them — replace them with something verifiable, such as a precise description of what the client receives.
A short form. Every required field you add is one more thing the visitor has to do before you hear from them at all. Ask only for what your sales team needs in order to call back — a name and one contact channel — and leave the rest to the conversation that follows.
Speed, and a page that works on a phone. Open the device report in your own ad account to see what share of your clicks arrive from phones, then load the page on that kind of handset yourself. A page weighed down with unoptimised images can lose the visitor before the headline is read — and you paid for that click either way.
When to build one
Build one when you have a campaign with its own message and you want to measure it separately from the rest of your website. Build one when you are launching a new product and do not want to disturb the existing site structure yet. And build one when you need a clean destination for a QR code, a flyer or an event.
Hold off when the sales message itself is not settled, or when what you are actually missing is a proper company profile site. A landing page will not rescue an offer nobody wants; it will only tell you early that nobody wants it, which is useful but is a different job. In that second case, a company website with a CMS is the better fit.
Cost and timeline
At Temei a landing page starts from 1,888,000₫ and is delivered in 3–5 business days from the moment the copy and images arrive. The price excludes VAT, the domain and hosting. That starting price covers a custom-designed page, optimised for speed and mobile, with a form wired to Zalo, email or Google Sheets, plus a guide so you can update the content yourself after handover.
The number of sections and the number of forms are what Temei uses to settle the final price. If the copy has to be written from scratch, that is a separate line item and should appear in the quote as one.
Frequently asked questions
Does a landing page need its own domain?
Not necessarily. It can live on a sub-path of your existing site, for example yourdomain.com/september-offer. That keeps the authority of your main domain and saves a cost. A dedicated domain only really earns its keep when the campaign needs a short name that people will read off printed material.
How long does a landing page stay useful?
Until the campaign message changes. When the next round comes, try rewriting the headline and the offer first, before deciding you need a new page. Ask for a handover that includes editing instructions, so you are not going back to the studio every time a sentence changes. Keeping the original page and copying it for the next campaign also lets you compare the two versions against each other rather than guessing which wording did better.
Do I need analytics in place from the start?
Yes, and before the first advertising money is spent. Without form-submission tracking you will know how many people reached the page but not how many actually left their details — which is the only thing the page exists to produce.
If your message is already settled and you just need a destination page to point ads at, the landing page design service explains what the package from 1,888,000₫ covers: message and structure, a custom design, a connected form, and instructions so you can keep the page current yourself.
