For many reasons, we came out against the phrase, "Click here." (We being a group of writers and editors.) Click here was inelegant and it lacked in semantics. We noticed a few ways of embedding a link:
- Click here.
- Click Blood-brain barrier to learn more.
- Infections of the brain are rare due in part to the blood-brain barrier.
The second isn't a mortal sin, but it does lack in semantics. It's a little Dick and Jane. A high school English teacher would sigh, hand it back to you, and quietly say, "I think you can do better."
Only the third offers an elegant way to blend hyperlinking with content delivery. Link too often--or to undesirable content--and readers will train themselves to stop clicking. Link to interesting content, and their AD/HD will keep them stuck like fly to paper.
"Sticky-ness" is a term that's used on websites. But don't aim for sticky; aim for good writing, and let sticky take care of itself.
