The short answer: Yes.
Wix templates are fully customizable, AND they are free to use.
There is a large selection of templates to choose from, and they can be updated without needing to know how to code.
We love this for our clients, as it makes editing your own website easy and stress-free.
Are These Templates Responsive?
We talk about it in more depth here, but the templates available in the traditional Wix Editor (instead of Editor X), are mobile-friendly, not fully responsive.
This means they won't keep the exact design experience as your desktop version, but will still be optimized for mobile devices.
Wix Paid Plans
Where paid plans comes into play is if you want to connect your own domain to your website.
If you want to connect your domain to your Wix website, (so it will be yourdomain.com instead of businessname.wixsite.com), you'll need to upgrade to a paid plan.
Connecting your own domain name is strongly recommend. This is so it'll start ranking in search results, and so it can be remembered easily if someone wants to visit your website directly.
The good news is that Wix plans are super affordable! They even offer a month-to-month option if you aren't sure about committing to a yearly plan.
