Fortunately, the process of researching keywords for your domain name is the same as finding effective keywords for other uses. You can use tools like Google Keyword Planner and KWFinder to search for terms that have both a high search volume and (ideally) low competition. Just remember that in this case, you’re looking for a keyword that represents your website and content as a whole.
Now I don’t want to pretend as if there weren’t any cases where WordPress is the only real option – there definitely are. If, for example, you want to run a website with a searchable database for real estate offerings. It’s also a great choice if you need a complex member area. You can find some tips on WordPress solutions in our Beginner’s Guide to WordPress.
I’ve made some use of Kirby CMS. It’s a really well put together flat file CMS. It takes some coding out of the box to get it set up as desired, but then it’s a pleasure to use. Advantages of not having a database include simpler setup, and the ease of version control of the whole site. Statamic is a similar option, though I’ve not spent any significant time using it.
We generally advise to stick to more conservative TLDs like .com, .net., or similar. However, I have seen endings like .pizza, etc. used more commonly so I think you can give it a go. As for which ending, I think that depends a little on the rest of your domain but, in general, I would prefer .cafe because it’s shorter and looks more pleasant in my opinion.
The one thing you didn’t discuss much in your article is how easy for the client it is, using the CMS *after* the developer walks away. One reason I love WP is I can show you how to add a new blogpost in 10m flat, regardless of your tech ability – and barring that, set up an email drop so it’s even simpler. October fits the mold of Joomla, Drupal, and a few others with a learning curve that’ll be quite a bit steeper for some clients.
