There are thousands of templates to choose from in WordPress’ own Theme Directory. Search for the types of themes you’d be interested in. If you’re setting up a newspaper search ‘newspaper’, if you need a site for your café search ‘cafe’. There’ll be dozens, if not hundreds, of contenders. Clicking on a theme takes you to its own page where you can see user reviews and preview the theme in action.
Using long tail keywords is now a waste of time. This is because of Google RankBrain. RankBrain is an AI (artificial intelligence), so to this new algorithm, all related long tail keywords are the same. It is now pointless to use such long tail keywords. What I would recommend, instead, is use Medium Tail Keywords along with LSI Keywords. This is the new way of keyword research! 😉
Your website needs a place to live on the web, and the quickest way to reserve your web address is to find a web host. There are a variety of cheap web hosting providers, and each one has a specialty. Look for a web host that offers a price that fits your budget, has the web tools you need to create your envisioned website, and provides support when you need help or have problems.
