The type of content they do/don’t accept. This will often be common sense (e.g. they don’t want plagiarized content or posts you’ve already published somewhere else), but the guidelines may also cover the topics they’re particularly interested in, or topics that they don’t want right now.

Whether they want you to send them an idea and outline, or a full draft. It’s best to stick to what the blog asks for here (though most won’t reject you just because you sent the wrong thing).

Who to send your pitch (or draft) to. This may be an editor, assistant or even a submission form rather than the blog owner.
