Have a URL that addresses the issue as clearly as possible.
Every time I see help documents that has something like: Menu → Settings → Advanced Settings → Network → Add, I cringe.
The URL should be something like https://example.com/settings/network/add. Plain and simple. Firefox is terrible at this and Chrome's are much better with items like chrome://settings/certificates, but many of them are inconsistent and not used from their own awful accordion style documentation, which goes on to break Rule 2.
Other times, I have a particular question and I can only find an answer perhaps on an outdated forum. The service I am dealing with, should have the canonical answer on a FAQ that does not suck. E.g. Does Webconverger support touch screens? Here have a look at: http://webconverger.com/faq/#does-webconverger-support-touch-screens.
Make the site Ctrl+F-able
One of my learnings about how people use http://greptweet.com/ is that people prefer Ctrl+F instead of actually using the search box.
Chrome's Ctrl+F is fast, gives great highlight indicators to matched word, number of matches and where they are in the document by markers on the scrollbar.
