Google my business is a Google service that allows you to showcase your business listings. There are several options in this service, including the option of creating a website.
However, in all honesty, this option isn’t very useful and is much less visible than if you had your own website created using CMS software such as Wordpress.
The advantage of having your own Wordpress-type website is that you can automate the publication of your website news directly in Google my business. And yes, these kinds of methods do exist to promote and enhance/update your Google my profile.
