Make sure Google can crawl and index all your pages and content easily, and that you're not using any tech, awkward (or missing) internal link structures, or content practices (e.g. video/animations with no parse-able text, interactive content w/ no parse-able text, etc) that stops Googlebot from accessing your work.
Create content that...
a) Addresses real problems that people are searching Google for.
b) Truly solves the searcher's problem, and takes them all the way through the solution (i.e. it can't just be "marketing" for your product).
c) Intelligently employs the words and phrases searchers actually type into Google (so do your keyword research and match your topics + headlines to the words + phrases they use).
d) Doesn't annoy or piss off users such that they click the back button and choose someone else's link instead of yours.
e) Earns links and amplification (see point below).
Have a great answer to the question: "Who will help amplify/link to this and WHY?" If you can nail that, and then get what you create in front of those right people/organizations, your ability to earn amplification, engagement, and links will be vastly better than simply trying to make stuff, then put it in front of likely linkers. Craft content the way Amazon crafts products - write the press release first. List the people who will want to share it/tweet it/post about it/write about it/link to it/etc. and then explain their motivations. Now you've got content that has the potential to earn the ranking signals you need.
