Your customers will find visiting your website on a regular basis, very informative and fun, if you update regularly. You don’t have to change the text and pictures on your main pages, you could just write a post or an article once or twice a week. This could be to tell your customers what’s new. Or it could be to advertise some current specials, or talk about new products or anything informative.
And if you post news regularly then, you will become an information source or an expert in your field. The more people that read your news and follow, the more links and word of mouth your website receives.
You could also engage your readers further by allowing them to leave comments, and you could respond, just like the comments section below.
