Most of the products here can tell you about your site traffic, though the amount of detail varies greatly among them, and it's often tied to premium account levels. For example, Weebly can not only show you page views and unique visitors for each day of the month, but also search terms used to get to the site, referring sites, and top-visited pages. Wix and uKit, at the other end, have nothing in the way of built-in site stats, instead requiring you to create your own Google Analytics account, and even that requires a paid account. Another drawback of that approach is that you can only see traffic from the preceding day and earlier; it's not up-to-the-minute, or even the hour.
The major player in the blog game is WordPress, a content management system (CMS) that powers millions of websites, including The New York Times, Quartz, and Variety. WordPress-powered sites are incredibly easy to set up, customize, and update—ideally on a daily basis. You aren't required to learn fancy-schmancy FTP tricks (though you can certainly use them if you like), and there are ridiculous numbers of free and paid WordPress themes and WordPress plug-ins to give your website a pretty face and vastly expanded functionality. Though WordPress dominates the blogging space, it isn't the only blogging CMS of note, however.
Top tip: Don’t just test your website yourself. You will be blind to some of its faults. Plus, you know how your site is supposed to work, so while you might find navigating it easy that’s not to say a stranger will. Get a fresh perspective. Ask family members and friends to test your site and give feedback. If they’re anything like our family and friends they won’t be afraid of offering criticism.
