Hmmm, now this is a bit more complicated. But thanks for the input, Don. I kind of get what you mean. Are you saying that a short domain is only worthwhile if it contains a good keyword, and a slightly longer one with a better keyword is better? If I haven't missed the point, then what about those 4Ls that are really only possible acronyms, not keywords on their own? I've always understood those to be valuable.
i elaborated, because domains or the understanding of value as applied to domains, is rarely based on a single premise.
as for 4Ls, their value began to surge, as the pool of "available to register" began to shrink.
the exceptions were those 4Ls which are actual words and following that are 4Ls which can be made into words/names of actual/potential websites... aka "the pronouncebles"
acronyms and their value would fit somewhere between "actual words and made-up" words, depending on who owns the domain and their ability/resoucefulness to market to end-user
the last group would be those 4Ls that are not words and the acronym potential is not as obvious or potential acronym usage is too low for speculation.
again, to go back to the point about "direct navigation"...
if the acronym chosen, can be substituted and accepted by the masses, in place of a domain with more characters, then it will become the shortest domain for that subject.
my view is, that the best domain is always the one that brings the most traffic...regardless to the number of characters therein.
note: when i speak of traffic, i'm referring to "converting traffic"
imo...
