Matt Ambrose of copywriterscrucible.com shares his list of 15 tips to give your copywriting some punch.  This list includes some seriously good advice from an experienced copywriter.  You could use these tips as a checklist when writing copy for ads to make sure your writing will be as effective as possible. My favorite part of this list is rather than just addressing the mechanics of advertising copywriting, he covers the type of language and tone you want to use as well.
