In order to spread the word about your business, you could invest in paid advertisements. Those ads would get sent out and hopefully be seen by the right people. Some of those people would, hopefully, then contact your company. That’s outbound marketing.
Inbound marketing is another, newer marketing strategy. In inbound marketing, the customers come to you. Blogs pay a big part in helping those customers find your business.
There are only so many pages on your website unless you have a blog, of course. A blog gives you a way to regularly update your online presence. Each time you write a new blog post, you give people another way to find you.
By writing about content that’s relevant to your industry and useful for potential customers, you make sure you attract people who are likely to be interested in the product or service your business provides.
