It’s yours!!! 
Of all the platforms available to you to market / promote your business online eg social media, business directories, etc there’s none you’re in total control over.
Social media platforms can ban or suspend you for no reason at anytime.
A directory listing can also go offline anytime due to the owners not continuing with it. Besides they reserve the right not to list you. While yet another downside is a potential customer also sees several other businesses and can contact someone else instead of you
But when a potential customer finds you on Google or any search engine and visits your website their attention is solely on your website. (Totally different ball game if they find what they are looking for; a valid reason to also keep your website updated).
I believe you’ll agree with me now that it’s a must have talking about your business website?
