Wikipedia is a good example. Google considers it a high value website (less so than before but still) while it only has a single article about each topic. Other projects have entire websites dedicated to the single topic, products, experts on staff, live support. I presented as an example to some google engineers the wp page on suicide that explains popular ways of doing it vs dedicated prevention projects. Today (for me) it ranks the topic: 1-3) news articles, 4) world health organization statistics, 5) wikipedia, 6) Suicide prevention.

ABC news, the NYT, WP and the WHO are considered high profile but the topic is not their area of expertise. Non of them would consider themselves the go-to place for people searching for it.
