Landing-page development costs depend on what is included: planning, copy, imagery, design, implementation, forms and measurement. This guide concerns a dedicated promotional page. In analytics, landing page can mean any page where a visit starts; that is a broader definition.
Define the reader and intended action
For an enquiry page, establish whose questions it should answer and what qualifies as a useful enquiry. Visits and clicks are not the same as purchases or qualified leads. Commissioning a page does not establish that the supplier can guarantee business results.
Separate the quotation into workstreams
Workstream | Possible scope | Client input |
|---|---|---|
Planning | Audience, structure and proposition | Objective and approval owner |
Copy and assets | Writing, photography and diagrams | Facts, evidence and permissions |
Design | Mobile and desktop layouts | Brand requirements |
Implementation | Build, CMS and deployment | Hosting and domain responsibilities |
Forms | Input, submission, completion and notification | Fields, recipients and data handling |
Measurement and handover | Agreed actions and instructions | Account owner and operating plan |
A supplied-copy build is not equivalent to a project requiring interviews and original writing. Align revisions, imagery, post-launch work, tax and recurring fees before comparing totals.
An illustrative Japanese-project budget
Item | JPY example |
|---|---|
Planning | 20,000 |
Copy and asset preparation | 40,000 |
Design | 70,000 |
Build and forms | 70,000 |
Measurement checks and handover | 20,000 |
Total | 220,000 |
This is a worked example, not a market benchmark. It excludes tax, photography, media spend and recurring hosting charges. A ¥160,000 quote with ¥60,000 of required missing work has the same aligned total as an inclusive ¥220,000 quote. Price bands alone do not establish quality or conversion performance.
A landing-page brief
Objective and measured action: [ ]
Audience, traffic source and questions: [ ]
Offer, price, conditions and evidence: [ ]
Call to action and form fields: [ ]
Copy, assets and rights-check owners: [ ]
Devices, publishing environment and integrations: [ ]
Approver, dates and revisions: [ ]
Measurement, maintenance and update owner: [ ]
Consolidate feedback through an accountable approver. Review structure, then design, then implementation. A structural change after the build is not the same as correcting a typo.
Acceptance should test actual behavior
Test | Expected result |
|---|---|
Mobile | Readable copy and controls without unwanted overflow |
Call to action | Correct form or destination |
Input errors | Clear feedback and a usable correction path |
Successful submission | Completion shown and recipient-side receipt confirmed |
Failed submission | No false success message |
Reloads and repeated clicks | Duplicate handling and measurement understood |
Handover | Required access, updates and support routes available |
Counting a button click as a completed enquiry may include failed attempts. Agree what confirms success with the measurement owner. Coordinate test submissions so they are distinguished from genuine enquiries.
Read the path from entry to a useful outcome
Hypothetical example: 200 visits produce 40 CTA clicks, 30 form arrivals, 10 successful submissions and six qualified enquiries. Submission rate is 5%; qualified-enquiry rate is 3%. These are not industry averages. Preserve the denominator and outcome definition instead of reporting an unexplained conversion rate.
- Few CTA clicks: examine audience fit and clarity.
- Few form arrivals: inspect links and transitions.
- Few completions: investigate errors and input requirements.
- Few useful enquiries: clarify eligibility and offer conditions.
Do not infer a dependable improvement from a small sample. Record changes in period, traffic, advertising and follow-up. Define production acceptance separately from ongoing optimization and agree who performs each.
