This is crucial. Your website is your home base. It's where your potential customers are going to come looking for you, to learn about you, what you stand for, what you offer, where to find you, and so on
. It is one of the most important interactions they have with your brand. If your website is poorly designed and difficult to navigate, not only will it show up poorly on search results, but it will also give your potential customers a bad first impression. Like they say, first impressions really are everything.
Invest in a website that properly represents who you are to your potential customers. The truth is, unless you have experience in designing and running a website, it's best to intrust this important task to someone who is familiar with it.
