I've done a lot of posts filled with advice. Some of them are rather old. Most were written after I noticed trends from a contest. All are completely buried and hard to find unless you use the editing label. But all are still relevant.
So I thought I'd repeat this general list of the different blurbs on writing and querying advice.
I highly recommend the posts on filtering and hyphens. Also the post on punctuation for a tag or beat. Those are problems I see on entries every year.
