When adding hyperlinks to the markup in paragraph-sized runs of text, how much of the text relevant to each link should be included?
So I know links that just say "here" or "this" are bad, but what about links that just pick one word to include and leave all the surrounding text out of the link? This seems to make it harder to spot the link and harder to click on it. On the other hand can including whole sentences in links be too much?
I was thinking that linking phrases, possibly noun phrases might be best, but I'm not an expert so I ask the experts here at UX.
Assume for the purposes of answering this question that we have control over the text as well as the placement of links, so rewording is also OK.
(I'm asking for editing posts here on Stack Exchange sites, but it seems to be a question relevant to user experience everywhere where hyperlinks are embedded in text.)
