A website is a representation of your business. It is where your customers engage with you and learn about your products and services. If you want your business to grow, you need to routinely update your site according to the latest market trends and content ideas relevant to your industry so it ranks high on search engines and generates quality leads.
Many businesses are not aware of the impact their website can have on their sales and thus do not think about updating it. But in this day and age, if you are not keeping up with the trends, you are losing out on value, customers, sales, and ROI.
