>I submitted two sites at the same time a few months ago, and one was accepted very quickly into the listings. The other was not, and I honestly believed the other to be a better site.
Assuming you are right -- that is not information the editors would have.
Think about it. Say, twenty million websites out there, and all of us editors looking for the best unlisted site, not listing any other sites until we find that one best one. Then, start all over again with the nineteen million, 999 thousand, 999 sites that are left. That's what it would take to list the best sites first. But it can't work that way.
It works this way instead. Editor picks category to develop. Why? Who knows, other than he thinks the category could profit by some work, and as a surfer he'd not mind looking at sites on that subject.
Then editor chooses some way of looking for appropriate sites. That might be unreviewed site pool, Google searches, spidering link lists, pulling URLs out of articles in specialty magazines, looking for websites of local organizations that he knows about, whatever.
Within that category and the potential sites found, editor picks one site to review first. Again, no comparison with all the other unlisted sites, just "does THIS site add something significant to the category? Yes: list; no: don't list."
It's as near random as designed disorder can make it.
So, where, in all of this, is there any way "good" sites have an advantage -- a better chance of being reviewed earlier? There are two ways (and note, both of them are not of the form "you go to the head of the line", they are "you get multiple chances to win a review, multiple lottery tickets".)
One: a "good" site is more likely to be findable by a variety of methods; a "poor" site is more likely to be invisible, or findable only by one way.
So in effect, the "good" site gets into multiple search method "lotteries" within its category, the poor site doesn't. And, so long as the editors do a good job of using many different ways of looking for sites, the good sites have that advantage.
(This is one of the reasons that the "disorganization" of editor site reviews works better than any conceivable method of "organization" -- and why some of us, at least, firmly repudiate attempts to be "organized".)
The second advantage of a "good" site depends on OUR definition of "good", not yours. OUR definition is that it provides unique content. Suppose you, say, wrote a biography of, say, Madonna and a much shorter biography of, say, Robert Shaw. It is obvious that fewer people are going to be looking for the lesser amount of content on the choral director. But that is all irrelevant. OUR question is, which site is more likely to provide information not already available online? The content on the more obscure ("less competitive") subject has an advantage, as it ought to.
Of course, having ten lottery tickets every day, rather than one, doesn't guarantee a quicker win -- as you have seen.
