Yes, you can! You can use WordPress yourself if you have the skills needed, or you can use platforms like Weebly, Wix and Squarespace. These platforms are very handy in getting you started with a website where budgets are very tight.
Most platforms offer a quick start process where you pick a template and then add your own content. Of course, this will mean that your website won’t be 100% in the way it looks, since many other website owners will have chosen the same template as you. You will also have to spend the time learning how to add and adjust the content to suit the message you are looking to convey, along with making sure that the site is optimised for success in the search engines.
Remember also that you are effectively renting your website and not owning it. If a platform makes a change or closes down (as Google Business Sites did in March 2024), then you will need to adapt quickly to those platform changes and likely need to start again.
