Balance the workspace and explanation
A tool page should not force users through a long article before they reach the input. At the same time, a blank app shell with only client-side content can be hard for crawlers and preview systems to understand. The best pattern is simple: tool first, useful explanation after.
What should be visible
- Specific H1 and short purpose text.
- Clear input and action labels.
- Empty result state before the user runs the tool.
- Data handling and processing notes.
- Limitations and FAQs written for that tool.
- Related tools and guides that match the task.
What to avoid
Do not render reconnect, debug, sample failure, or internal status messages in public HTML. Do not show fake output as if the user already ran the tool. And do not rely on hover-only explanations for important content.
FAQ
Should the app be a single page or many pages?
The interface can feel single-page, but important tools and guides should keep canonical URLs for search, sharing, and direct navigation.
Can content go below the tool?
Yes. That is often the cleanest arrangement for user experience.
