Content gap
A content gap is a question users ask that your documentation does not answer, often discovered through unanswered chatbot queries or failed searches.
Traditionally, content gaps were found through keyword research or support ticket reviews. Docs AI chatbots surface them directly: unanswered questions show where readers needed help. Some indicate missing content; others reveal retrieval or configuration problems.
Review the questions, group recurring topics, and check them against the published documentation. Frequency helps prioritize work, alongside the importance of the topic and the effort needed to fix it.
A grounded chatbot is a prerequisite. An assistant that guesses instead of saying "I don't know" hides the gaps it should be reporting. Biel.ai logs unanswered questions as content gaps for exactly this reason.
Frequently asked questions
How do I find content gaps in my docs?
Review unanswered chatbot questions, searches with no useful result, and recurring support tickets. Compare them with your existing docs to see whether the answer is missing or hard to find.
Are content gaps always missing pages?
No. A gap can be an existing page that is unfindable, outdated, or written so a retrieval system cannot match it to the question. The fix may be a rewrite, not a new page.
