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.[10] 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.[11] 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.
One way marketers can reach out to consumers, and understand their thought process is through what is called an empathy map. An empathy map is a four step process. The first step is through asking questions that the consumer would be thinking in their demographic. The second step is to describe the feelings that the consumer may be having. The third step is to think about what the consumer would say in their situation. The final step is to imagine what the consumer will try to do based on the other three steps. This map is so marketing teams can put themselves in their target demographics shoes.[76] Web Analytics are also a very important way to understand consumers. They show the habits that people have online for each website.[77] One particular form of these analytics is predictive analytics which helps marketers figure out what route consumers are on. This uses the information gathered from other analytics, and then creates different predictions of what people will do so that companies can strategize on what to do next, according to the peoples trends.[78]
Using an omni-channel strategy is becoming increasingly important for enterprises who must adapt to the changing expectations of consumers who want ever-more sophisticated offerings throughout the purchasing journey. Omni-channel retailing involves analyzing consumer behavior from a broad perspective, and studying what influences buying habits.[29] Retailers are increasingly focusing on their online presence, including online shops that operate alongside existing store-based outlets. The "endless aisle" within the retail space can lead consumers to purchase products online that fit their needs while retailers do not have to carry the inventory within the physical location of the store. Solely Internet-based retailers are also entering the market; some are establishing corresponding store-based outlets to provide personal services, professional help, and tangible experiences with their products.[30]

Prioritizing clicks refers to display click ads, although advantageous by being ‘simple, fast and inexpensive’ rates for display ads in 2016 is only 0.10 percent in the United States. This means one in a thousand click ads are relevant therefore having little effect. This displays that marketing companies should not just use click ads to evaluate the effectiveness of display advertisements (Whiteside, 2016).[48]
