# of words in text Link Description- more or less?

[Alphawolf]

Hey folks,

In AEBN they have the hosted galleries and allow you to select the # of words for the description from a dropdown.

3,4 or 5 word descriptions.

Does anyone have any data that shows a shorter or longer description is more likely to get people to click?

I sort of like the 5 word description for link text because without an image I feel the more descriptive the better.

But there must be a reason they have the drop down and the choice for just 3 word descriptions.

What do you pick and have ya played around between 3 vs 5 word descriptions? What tends to be the common thought on which is better in this case?
