Social media is used to facilitate two-way communication between companies and their customers. Social media outlets such as Facebook, Twitter, Tumblr, Pinterest, Snapchat and YouTube allow brands to start a conversation with regular and prospective customers. Viral marketing can be greatly facilitated by social media and if successful, allows key marketing messages and content in reaching a large number of target audiences within a short time frame. Additionally, social media platforms can also house advertising and public relations content..
Unlike most offline marketing efforts, digital marketing allows marketers to see accurate results in real time. If you've ever put an advert in a newspaper, you'll know how difficult it is to estimate how many people actually flipped to that page and paid attention to your ad. There's no surefire way to know if that ad was responsible for any sales at all.
Personal selling involves an oral presentation given by a salesperson who approaches an individual or a group of potential customers. Personal selling allows for two-way communication and relationship building that can aid both the buyer and the seller in their goals. Personal selling is most commonly seen in business-to-business marketing (e.g.: selling machinery to a factory, selling paper to a print shop), but it can also be found in business-to-consumer marketing (e.g.: selling cars at a dealership).

The development of digital marketing is inseparable from technology development. One of the key points in the start of was in 1971, where Ray Tomlinson sent the very first email and his technology set the platform to allow people to send and receive files through different machines. However, the more recognisable period as being the start of Digital Marketing is 1990 as this was where the Archie search engine was created as an index for FTP sites. In the 1980s, the storage capacity of computer was already big enough to store huge volumes of customer information. Companies started choosing online techniques, such as database marketing, rather than limited list broker. These kinds of databases allowed companies to track customers' information more effectively, thus transforming the relationship between buyer and seller. However, the manual process was not as efficient.
Porter's approach was the dominant paradigm throughout the 1980s. However, the approach has attracted considerable criticism. One important criticism is that it is possible to identify successful companies that pursue a hybrid strategy - such as low cost position and a differentiated position simultaneously. Toyota is a classic example of this hybrid approach. Other scholars point to the simplistic nature of the analysis and the overly prescriptive nature of the strategic choices which limits strategies to just three options. Yet others point to research showing that many practitioners find the approach to be overly theoretical and not applicable to their business.
Pixels track everyone who comes to your site, and you can build custom audiences around them.

And your conversions will skyrocket.
