Short answer: Landing page optimization services in the US are priced three ways. Agencies publish $3,000 to $15,000 per project or $1,500 to $5,000 and up a month on retainer, freelance specialists charge $50 to $200 an hour with projects from $500 to $4,000 for basic work, and self-serve software runs $50 to $100 a month. Which one you should buy depends on one number: how many visitors the page gets. Below roughly 30,000 to 80,000 visitors per variation, no service can run a valid A/B test on your page, so what you are really buying is the audit and the rewrite. A tool does that part for $49 a month billed yearly; the rest of the fee buys judgment and a test program you may not have the traffic to use.
Price ranges are published asking prices from one US agency's pricing guide (Clicks Geek, April 2026) and from service pages read in September 2026. No neutral body audits what optimization services charge, so treat every figure as a quote, not a benchmark. Sample sizes use the standard two-proportion formula at 95 percent confidence and 80 percent power.
How much do landing page optimization services cost?
Nobody tracks this market, so what exists is agencies publishing their own ranges. One US agency's 2026 guide is unusually specific, and its numbers line up with the service pages of its competitors, so it makes a workable planning table. Here is the full ladder, with what each tier usually includes.
| Route | Published price | What you usually get | Turnaround |
|---|---|---|---|
| Agency, project | $3,000 to $15,000 per project; the guide puts "basic optimization of a simple page" at $1,500 | Analytics and recordings review, heuristic audit, hypotheses, wireframes and copy, a rebuilt page, sometimes a first test | Weeks to a couple of months |
| Agency, retainer | $1,500 to $5,000 and up a month; $500 a month for "basic monitoring and quarterly tests" | Ongoing test program: backlog, variant builds, A/B setup, monthly readout | First variant typically inside the first month; one agency says the cadence after that "depends on your traffic" |
| Freelance CRO specialist | $50 to $200 an hour; $500 to $4,000 for basic projects, $2,000 to $16,000 for comprehensive ones | A written review and a call, often a redesign of one page | Days to weeks |
| Specialist one-off audit | CRO practitioners have quoted $2,500 to $4,000 for a one-off audit; one US copywriter publishes a $900 live-page critique | A document, sometimes a video walkthrough, no implementation | About 10 business days |
| Self-serve software | The guide puts DIY tools at $50 to $100 a month; Converto is $49 a month billed yearly for 25 audits | Scored audit of copy, calls to action, layout, speed and AI-readability, ranked fixes, rewritten copy, repeatable | Minutes per page |
Two things the table hides. The agency figures scale with page count and traffic, so a quote for five paid landing pages is not five times a one-page quote but it is not one times it either. And "free audit" offers, which most agencies lead with, are a sales step: one agency promises "a written read within 48 hours", and what arrives is a short list of observations plus a proposal. That is fine, as long as you know that is what it is.
What a landing page optimization service actually does
The scope is broader than the name suggests. One agency lists its deliverables as a tracking audit, click and scroll maps, session recordings, a message-match review, a hypothesis backlog, wireframes and copy, variant builds, A/B test setup, before-and-after measurement, form analytics and a monthly readout. That list is honest about where the money goes: only three of those eleven items are about the page itself. The rest are about instrumenting your traffic and running experiments on it.
That split matters because the two halves have different requirements. The page half (message match, copy, calls to action, form depth, speed) can be done on any page today, from the public URL. The experiment half needs traffic, and a great deal more of it than most buyers expect. If your page does not have it, you are paying for the page half at the experiment half's price.
The traffic test: can a service run a test on your page at all?
Before you read another proposal, run this arithmetic on the page in question. An A/B test that can detect a 10 percent relative lift on a page converting at 2 percent needs about 81,000 visitors per variation, so about 162,000 in total, at 95 percent confidence and 80 percent power. At a 5 percent conversion rate it needs about 31,000 per variation. At 10 percent, about 14,800. A cruder rule of thumb is about 1,500 conversions per variation. The full table is in our guide to A/B test sample size.
Now take a typical paid landing page: 5,000 visitors a month, converting at 3 percent. Detecting a 10 percent lift needs about 53,000 visitors per variation, which is 21 months of traffic for one test. A retainer at $2,500 a month would cost $52,500 before that single test could read. Even a 20 percent lift, which is a large change to detect, needs about 14,000 per variation and five to six months. Below that traffic, the test program in the proposal is not a program, it is a line item.
This is not an argument against services. It is an argument for buying the right half. A page with 5,000 visitors a month still has copy that does not match the ad, a form with eight fields and a button that says "Submit", and all of that can be found and fixed without a test. It is the part a landing page audit does in minutes, with the measurement behind each finding, and the part you can re-run after every change for the same subscription.
Which landing page optimization service should I choose?
Decide by traffic and by what you spend to buy it, in that order.
| Your page | What to buy | Rough cost | Why |
|---|---|---|---|
| Under 10,000 visitors a month, under $5,000 a month in ad spend | An audit tool, plus your own designer or page builder for the changes | $49 to $99 a month | No test can read at this traffic; the audit and rewrite are the whole job |
| 10,000 to 50,000 visitors, $5,000 to $20,000 a month in spend | An audit tool for the findings, a freelancer or specialist for the redesign of the two or three pages that matter | $49 a month plus $500 to $4,000 per page | Large lifts are testable at the top of this range; most changes still are not |
| Over 50,000 visitors, over $20,000 a month in spend | An agency retainer, with the audit run first so the first month's backlog is already written | $1,500 to $5,000 and up a month | Tests can read within a quarter, and the fee is small against the spend it protects |
The middle row is where the most money is wasted, in both directions. Teams there sign retainers that cannot test, or they do nothing because a retainer feels too big. The cheap answer is to buy the audit, fix what it names, and pay a specialist by the page for the rebuild. If you go the freelance route, a vetted freelance specialist whose past page work you can inspect is worth the search; the $50 to $200 hourly range is wide because the market has no floor.
The same decision on a whole account, rather than one page, is worked through in CRO agency vs CRO tool, and the full price ladder including enterprise programs is in how much CRO costs.
Is landing page optimization worth it?
Work it out from the click price, not from a promised lift. A page receiving $5,000 a month of paid traffic at $2 a click gets 2,500 visitors. At 2 percent it produces 50 leads at $100 each. If fixing the message match and the form takes it to 2.5 percent, the same $5,000 produces 62 leads at $80 each, and that saving repeats every month the traffic runs. Whether the fix produces that half a point is something only your numbers can show afterward, which is exactly why you should run the audit before the retainer: it is the only step in the process whose cost does not depend on the outcome.
For a page that is the destination of every campaign, such as a B2B demo request page, the arithmetic is sharper still, because the visitor has already decided to talk to you and every field and script between them and the form is a cost you can count. For paid search pages, the PPC landing page optimization guide covers what Google itself measures on the page your ads land on.
What to check before you sign a landing page optimization contract
Five questions separate the proposals worth paying for from the ones that will bill you for a test that never reads.
What is your traffic threshold? A good agency will tell you the page cannot support a test and quote the page work alone. A bad one will sell the retainer anyway.
Who owns the variants and the data? Wireframes, copy and test results should be yours at the end, in files you can open without their tools.
Does the fee scale with pages, traffic or tests? All three are common, and a quote for one page can double when the second page is added.
What does month one contain? If the answer is "research", ask what they would do with an audit that already lists the findings. Bringing that list to the first meeting shortens month one, and the agency landing page audits page shows how agencies use the same report on the client side.
What happens when a test loses? Most do. The honest answer describes what they learn from it; the dishonest one promises the next test will win.
What no service will fix
The page is not the whole funnel. If the offer is wrong, the best copy on earth makes the wrong offer clearer. If the traffic is wrong, a better page converts more of the wrong people. If the price is wrong, the form field count does not matter. A service, and a tool, can only tell you what is on the page and what to change about it. The offer, the audience and the price are decisions, and they are yours before they are anyone's to optimize.
Paste your page and see what is leaking
Drop in any live URL and Converto audits the copy, layout, CTAs, speed, and AI-readability of the page you already have, then hands you ready-to-ship variants to lift signups and sales. Suggestions are data-informed, not guarantees.
