Use an LLM to turn a clear website brief into a proposed sitemap, page layouts, draft copy, and visual direction—then review and test the result before launch. Start with structure, not styling: the model can help you plan and iterate, but its output is a draft that needs human checks for accessibility, functionality, security-sensitive behavior, and search basics.
What an LLM can—and cannot—do for website design
An LLM can help translate a plain-language description into a first pass at site structure, page content, and design ideas. Depending on the platform, it may generate editable pages or help revise an existing project. For example, Microsoft Power Pages documents a workflow that generates a sitemap, homepage layout variations, and suggested pages from a description. It also notes that generated pages do not automatically create forms or lists; those may need to be added separately in its design studio. That is a product-specific capability, not a guarantee for every AI website builder. Microsoft Power Pages documentation
Think of the model as a drafting and iteration aid, not a substitute for design judgment or quality assurance. A polished preview does not prove that links work, forms submit correctly, layouts hold up on mobile, or sensitive features are secure. The amount of control and automation depends on the product and the way it is connected to your site.
Prepare a brief the model can use
Vague requests tend to produce generic sites. Before prompting, collect the information the model needs to make meaningful choices. Include what you know; ask it to identify gaps instead of silently inventing facts.

- It can be a gift option
- Purpose: What should the site help visitors understand or do?
- Audience: Who will use it, and what questions or needs bring them there?
- Pages: List required pages and any content that must appear on each.
- Visitor actions: Note actions such as contacting your team, booking, signing up, or purchasing.
- Brand direction: Supply brand assets and describe the desired tone, visual references, colors, and typography constraints.
- Accuracy requirements: Identify facts, policies, product details, and copy that must not be changed or made up.
- Technical constraints: State the platform, existing design system, integrations, publishing needs, and any required functionality.
Do not put passwords, API keys, private customer information, or other secrets into prompts. If you need the model to work with sensitive configuration, use a safe placeholder and handle the real value through your platform’s secure settings.
Start with the sitemap prompt
Ask for structure before requesting a finished design. For example:
“Plan a website for [business or project]. The audience is [audience], and the main goal is [goal]. Propose a sitemap and, for each page, list its purpose, main sections, key visitor action, and information it needs. The site must include [required pages and functions]. The brand should feel [visual and tone direction]. Do not invent company facts; flag anything you need me to supply. Show the sitemap first, then wait for approval before drafting page copy.”
Review the proposed navigation and page list. Ask for missing pages or elements explicitly before moving on. A missing privacy page, an unclear service path, or a buried primary action is easier to correct at the structure stage than after styling multiple pages.

Once the sitemap is sound, ask for page sections and draft content. Specify the audience, purpose, desired hierarchy, and any factual boundaries again where needed. Have the model label assumptions or unanswered questions rather than filling gaps with plausible-sounding details.
Refine one category at a time. A focused request makes it easier to judge whether a change helped and to undo it if it did not. Useful passes include:
- Structure: Reorder sections, add missing content, or clarify the path to a key action.
- Visual hierarchy: Make the primary action, headings, and supporting information easier to distinguish.
- Typography and color: Adjust the type scale or palette while respecting brand constraints.
- Responsive behavior: Describe what should change at narrow widths and inspect the result in the actual preview.
- Content tone: Make copy clearer or more consistent without altering approved facts.
- Accessibility: Request semantic headings, meaningful link text, keyboard usability, and text alternatives for informative images, then verify them.
After each meaningful change, inspect the live preview rather than relying only on the model’s description. Keep a known-good version or use your platform’s version history so you can recover from a revision that breaks a layout or removes content. The plain-language brief, preview, and iterative workflow is also described in TechRadar’s general workflow guide; it is practical secondary reporting, not a controlled comparison of every tool.
Choose a workflow that matches the project
There is no universally best way to use an LLM for a website. Choose based on how much source-code control you need, whether a site already exists, your comfort reviewing implementation, and how publishing and hosting will work.
Use an integrated visual builder for a new site
A visual platform is a natural fit if you want generation and page editing in one environment. Check what the platform actually generates and what you must add yourself. Power Pages, for instance, documents sitemap and page-layout generation while separately noting that forms and lists are not created automatically. Confirm the workflow for your selected product before relying on generated pages to cover all required functionality. Power Pages site-generation documentation
Connect an AI tool to an existing site carefully
If you already use a platform or design system, an integration may let an AI tool work with project elements instead of starting from scratch. Elementor describes an MCP workflow that uses external AI tools with Elementor and WordPress. Webflow describes its MCP server as exposing project elements, styles, components, collections, assets, and related site data to AI tools. These are vendor descriptions of their own capabilities, not independent evaluations. Before connecting an agent, check what it can access, which actions it can perform, and what review or approval controls are available.

Use a coding assistant when implementation control matters
A coding assistant can help draft or revise code when you need direct control over implementation or an existing codebase. You remain responsible for checking how changes fit the project, whether behavior is correct, and whether accessibility and security requirements have been addressed. If you cannot confidently review a security-sensitive feature, get a competent review before publishing it.
Review the site before launch
Generated pages can look finished while important details remain broken or incomplete. Test the actual site and its critical visitor paths, not just the content of a prompt or a static preview.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitches- Pages and navigation: Open every page, follow each navigation item, and check that links lead where their labels promise.
- Forms: Submit each form with valid and invalid input. Check confirmation messages and where submissions are delivered.
- Responsive layouts: Inspect narrow and wide viewports. Look for clipped content, overlapping controls, unreadable text, and awkward navigation.
- Accessibility: Check keyboard access, visible focus, meaningful link text, heading order, and useful descriptions for informative images. Ask people who rely on assistive technology to test where feasible; a request to an LLM is not verification.
- Accounts and payments: Test the exact expected behavior, including relevant error and confirmation states, before making these flows available to visitors.
- Code and security: Review generated code and configuration, especially anything handling accounts, payments, permissions, or user data. Keep secrets out of prompts and client-side code.
- Content: Verify names, prices, policies, claims, and other important facts against authoritative material. Remove unsupported claims and generic filler.
Do not infer a universal defect rate from warnings about AI output. The practical point is that generated work needs verification, and both accessibility capabilities and coding workflows vary. W3C’s Web Accessibility Initiative provides accessibility guidance and resources for checking web content.
Make the site findable without chasing AI-search tricks
Google says existing SEO fundamentals remain relevant to its AI search features. Its guidance emphasizes content that can be crawled and found, useful information presented in text, relevant supporting media where it helps, a good page experience, and structured data that matches what visitors can see. Google says special AI markup or a separate machine-readable file is not required for a page to appear in AI Overviews or AI Mode. Search features and guidance can change, so check Google’s current documentation when planning a launch.
Write for people who need the information, not for a supposed ranking shortcut. Google’s guidance warns against producing many pages with little added value under its scaled content abuse policy. Do not publish large batches of thin, unverified prompt-generated pages or rely on claims that a special AI-optimization trick replaces useful content and sound SEO fundamentals.

The generated site looks generic
The prompt may not distinguish your audience, purpose, brand constraints, or required content from a generic website brief. Supply those details, include examples of the desired direction, and ask the model to list missing information rather than inventing it. Review the sitemap before asking for polished styling.
A page or feature is missing
Do not assume page generation creates every feature. Compare the result with your approved sitemap and test the required functions. In Power Pages, for example, generated pages do not automatically create forms or lists; add those separately in its design studio when needed.
A revision breaks something that previously worked
Give the model a narrower change request, inspect the affected page and related flows in the preview, and restore a known-good version if necessary. Avoid asking for several unrelated changes in one pass.
Recommended Free Tools
The design appears accessible but is difficult to use
A prompt asking for accessibility does not verify the result. Test keyboard navigation, focus visibility, headings, link text, and image descriptions in the actual page. If your workflow does not provide a reliable way to evaluate accessibility, arrange a competent review rather than treating visual polish as proof.
The preview passes, but the live site does not
Test the published site and its real forms, links, account flows, and payment flows. A convincing preview is not proof that production behavior or security is correct; review the deployed configuration and integration behavior before launch.
Frequently asked questions
Can ChatGPT design a website?
An LLM can help plan pages, draft copy, and suggest visual direction. Whether it can generate editable pages or change a live project depends on the platform and integrations you use. You still need to inspect and test the result.
Do I need special markup to appear in Google AI Overviews?
Google says no special AI markup or machine-readable file is required for AI Overviews or AI Mode. Its guidance points site owners back to existing SEO fundamentals.
