Keyword research
We need to know and to uncover the words and phrases that searchers are actually using to solve or to get answers to the problem that they are having in your world. Those should be problems that your organization, your website is actually working to solve, that your content will help them to solve.
What you want here is a primary keyword and hopefully a set of related secondary keywords that share the searcher's intent. So the intent behind of all of these terms and phrases should be the same so that the same content can serve it. When you do that, we now have a primary and a secondary set of keywords that we can target in our optimization efforts.

I mean look great from a visual, UI perspective and look great from a user experience perspective, letting someone go all the way through and accomplish their task in an easy, fulfilling way on every device, at every speed, and make it secure too. Security critically important. HTTPS is not the only thing, but it is a big part of what Google cares about right now, and HTTPS was a big focus in 2016 and 2017. It will certainly continue to be a focus for Google in 2018.
