Writing documentation that ranks and converts
Good documentation answers the questions people search for, and shows them how to get started. How to structure docs so they are found, read and acted on.
Documentation is a search page
People rarely search for a product's name. They search for the task they are stuck on. Documentation that names the task in its title and answers it in the first paragraph is often the most visited part of a technical site.
Structure for scanning
- One task per page. "Connect to the API with a key" rather than "Authentication".
- Answer first. The first paragraph should say what to do; the rest explains why and how.
- Show the code. A complete, copyable example beats three paragraphs of description.
- Link forward. End each page with the next likely task.
Make it readable by machines too
Agents read documentation to decide whether a tool can do a job. Clear headings, stable URLs, a Markdown version of each page and an index of pages help them find the right one. Describe limits and errors plainly; an agent that hits an undocumented error will often give up.
From reading to trying
Conversion in documentation is not a sales pitch. It is the moment a reader tries the thing. Make that easy: a free tier, a sandbox, or a single command that works. Put the getting-started page in the main navigation and keep it short.
Keep it current
Out-of-date documentation costs trust faster than missing documentation. Date your pages, review the most visited ones regularly, and remove pages for features that no longer exist.
A simple test
Pick the five questions customers ask most. Search for each. If your docs do not answer it on the first page you land on, start there.
