Digital Marketing
Digital marketing is a broad term that describes a set of marketing processes that utilize all available digital channels to promote a product or service or build a digital brand. Digital marketing has come to succeed in traditional marketing and the transition from paper and newspaper ads to Facebook and PPC campaigns.
The channels that make up digital marketing include Web sites, Social media platforms, Banner placement, email marketing, mobile marketing, SEO, pay-per-click campaigns, Web TV, SMS, billboards, and anything else with a digital foundation.

Internet Marketing
Internet marketing is a subset of digital marketing. It is in fact the most important component since the majority of digital marketing activities fall within the boundaries of Internet marketing. We will see below how digital marketing budgets are spent and their relationship with Internet marketing.
The major channels of Internet Marketing are:
Web site – Either a personal website or a corporate website or even a personal blog hosted on a shared platform (like WordPress or Tumblr). For many campaigns, a website is the starting point and the destination i.e. you run a digital marketing campaign to promote a website (starting point) to get more visitors (destination).

Search Marketing (SEM) – Search Marketing is the basis of Internet Marketing and consists of two important activities, SEO and PSA.
SEO has to do with optimization techniques to achieve higher rankings in Search engines. It has two major components: On-Page SEO and Off-Page SEO.
Paid Search Advertising (PSA) is about getting visitors by placing ads on search engines. The most popular approach is the Pay Per Click (PPC) and the most well-known tool is Google Adwords which lets you advertise on the Google and partner network.

Social Media Marketing – Social media marketing is another component of Internet marketing and one that is gaining a lot of attention in the last couple of years. Millions of users spend a considerable amount of their online time on Facebook, Twitter, Google+, Instagram, Pinterest, YouTube, Linked In, and on other SM platforms and this fact alerted digital marketers to take SM seriously and make it a part of the digital marketing campaigns.

Content Marketing – Since 2011, content marketing has become the new SEO. This simply means that good content has become again the foundation of SEO and it is through content that you will build a better Internet presence and not through cheap link-building techniques.

Email Marketing – Email is not dead but on the contrary, it is one of the most important tools in every digital marketing campaign. Despite the influence of social media, email is still the most efficient way to convert visitors or readers into customers.
