1. You have nothing retrievable to cite
The most common cause by far. Answer engines cite pages that answer a specific question factually. Most sites have only marketing pages and a blog, neither of which is shaped to be extracted from. A landing page argues that you are good. It does not state what something is, what it costs, how it works, or what its limits are. There is nothing for a model to lift. Fix: publish factual, narrow pages — one topic each, definition in the first sentence. Documentation and help-centre content is consistently the most-cited vendor page type.2. Your pages are not crawlable or not renderable
If body text requires JavaScript execution, many retrieval crawlers will not see it. Content behind auth, behind a cookie wall, or blocked inrobots.txt is invisible.
Fix: confirm body content is present in the served HTML. Check robots.txt does not block the pages you want cited. Do not gate documentation behind a login.
3. Your pages are too broad
A page covering ten topics competes for none of them. Models retrieve to answer a specific question, and a narrow page that answers it precisely beats a comprehensive guide that mentions it. Fix: split. One page, one thing.what-is-x outperforms the-complete-guide-to-x.
