With offline marketing, it's very difficult to tell how people are interacting with your brand before they have an interaction with a salesperson or make a purchase. With digital marketing, you can identify trends and patterns in people's behavior before they've reached the final stage in their buyer's journey, meaning you can make more informed decisions about how to attract them to your website right at the top of the marketing funnel.
If you really want to drive big time traffic to your blog, keywords and SEO have to be a part of your strategy. People get really nervous these days when you suggest doing something in the name of SEO, but remember, search engine optimization is fine when done right. More than fine - it’s wonderous! You get targeted traffic from Google, and users find the information and answers they’re searching the web for.
