1. Be fetchable. The most common reason a page is not cited is that it was not retrieved. Check robots.txt, check that the page is not noindex by accident, check that it is in your sitemap and that the sitemap returns 200.
2. Answer in the first paragraph. If the page exists to answer a question, answer it before the context, the history and the pitch. A passage that needs three paragraphs of setup cannot be lifted.
3. Use headings as questions where that is honest. Not keyword-stuffed H2s — real questions people ask, with the answer directly underneath. Your own Search Console query list is the best source for the phrasing, because those are questions you are already being shown for.
4. Make claims checkable. Say where a number came from and when. This is good practice generally and it happens to be what makes a passage safe for a system to quote.
5. Declare what the page is. Valid JSON-LD for the page type, the author and the date. Not because schema forces a citation, but because a broken or missing declaration leaves it to be inferred.
6. Kill the near-duplicates. Forty pages that differ by a town name are the least quotable content you can publish, and they are a real risk of being treated as low quality in ordinary search too.
7. Then stop. The rest of the advice circulating is untested. Spending a quarter on it instead of on the seven items above is a poor trade.
