The three stages of inbound marketing are attract, convert, and close.
The first stage, attract, is all about getting found by the right prospects. This is done through SEO, content marketing, and social media.
The second stage, convert, is all about converting those prospects into leads. This is done through lead capture forms and lead nurturing.
The third stage, close, is all about converting those leads into customers. This is done through sales and marketing alignment, and effective lead management.
