You do not need to specify layouts, frameworks or design systems. Explain the business, the people the website must help, what those people should be able to do and anything you strongly like or dislike. A capable agency should translate that into the technical brief.
Start with the business problem
Say what is difficult today. Customers may not understand the services, bookings may happen through scattered messages, staff may repeat the same explanations, or the current site may no longer match the business.
Describe the important visitor
Who usually arrives, what are they trying to decide and what concern stops them from taking the next step? This is more useful than asking you to choose a homepage layout.
Share references as reactions, not instructions
A reference link does not mean copy the whole site. Say what you like: the calm spacing, the way products are shown, the navigation or the tone. Also say what you do not want.
- Existing logo and brand files
- Two or three useful reference links
- Competitors customers compare you with
- Current service or product information
- Any legal, policy or operational constraints
Let the agency do the translation
The agency should turn your input into goals, content needs, page structure, functions and a visual direction. You should be able to react to something concrete before approving the full implementation.
Related questions
01What if I explain the idea badly?
That is normal. Your words are source material, not a prompt sent straight into a builder. The agency is responsible for asking useful follow-up questions and writing the proper brief.
02Do I need all the website text before we start?
Not always, but the project should clearly assign who drafts, supplies and approves the content.
