Inbound Marketing is a process that helps you to attract visitors to your website through great content, convert them into leads using tools like calls-to-action and landing pages and close them as customers by nurturing those leads through email marketing.
Outbound is the old way of doing marketing. Outbound Marketing is based on interrupting people on TV, on the radio, newspapers, magazines, and on the internet with ads to get their attention. People are tired of being interrupted with ads and they are getting better and better at blocking them.
Attracting the right customers is your first challenge. Therefore it’s important to develop a custom digital marketing strategy to target your ideal customers through blog entries that talk directly to your potential buyer.
Closed-loop analytics lends insight into the entire customer lifecycle -- from the time they first interact with you, to the time they become a customer. It helps tremendously with Sales and Marketing alignment, because you can actually see what activities are most likely to yield a customer -- "closing the loop" on your marketing efforts.
