Languages seem to be Site123’s thing. Not only is the editor available in more than 20 of them (including languages such as Turkish, Arabic, Romanian), they also feature multilingual websites. The editor is relatively restrictive, a bit like GoDaddy’s GoCentral. If you just want to get the website job done, without becoming too creative this might suffice. But you have to be aware that their template system can be a bit on the restrictive side.
You can even go beyond the search engine and find out what users are searching for when on your site, what they’re clicking on when they reach specific pages, and what your most popular (and least popular content) is. This can be especially powerful for eCommerce shops, but is also relevant to blogs. Pages that don’t perform well can be expanded upon and improved to meet user needs and expectations.
These services can host your content on their servers free of charge, but in exchange for that zero cost, your online destination will have a less-than-elegant domain, such as jeffreylwilson.tumblr.com. That might be fine for a personal blog, but it will look too low-rent for a business that wants people to trust it enough to pay for whatever it's selling.
