Online advertising is about a multitude of strategies. There are both differences and commonalities compared to internet advertising. Digital one refers to different activities and development plans involving all digital channels, while the internet one is a subcategory of the first. Rather than digital advertising, inbound is a unitary strategy of specific online strategies digital marketing agencies use to attract potential customers to the content/digital assets offered. Inbound marketing relies heavily on metrics and focuses on attracting customers and driving them through sales.
