Two other practical limitations can be seen in the case of digital marketing. One,digital marketing is useful for specific categories of products,meaning only consumer goods can be propagated through digital channels.Industrial goods and pharmaceutical products can not be marketed through digital channels. Secondly, digital marketing disseminates only the information to the prospects most of whom do not have the purchasing authority/power. And hence the reflection of digital marketing into real sales volume is skeptical.[citation needed]

O GPRs electrónico (e-GPRs) ou iGRPs (“i” de interactivo), consiste em estimar o número de utilizadores únicos[4][5] (diferente de visitas: número de visitantes que acede a um website num determinado período de tempo, a partir de uma morada IP única; se um utilizador visitar o mesmo site duas vezes no mesmo período, apenas é considerado um visitante) que serão alcançados através de qualquer canal online e correlacioná-lo com o número de impressões. O que cria uma relação (e-GPRs) que pode ser comparada com o GPRs tradicional, o que vai permitir que o Return on investment (ROI) da campanha de b-Marketing possa ser optimizado.

Digital marketing became more sophisticated in the 2000s and the 2010s, when[13][14] the proliferation of devices' capable of accessing digital media led to sudden growth.[15] Statistics produced in 2012 and 2013 showed that digital marketing was still growing.[16][17] With the development of social media in the 2000s, such as LinkedIn, Facebook, YouTube and Twitter, consumers became highly dependent on digital electronics in daily lives. Therefore, they expected a seamless user experience across different channels for searching product's information. The change of customer behavior improved the diversification of marketing technology.[18]
Influencer marketing: Important nodes are identified within related communities, known as influencers. This is becoming an important concept in digital targeting. It is possible to reach influencers via paid advertising, such as Facebook Advertising or Google Adwords campaigns, or through sophisticated sCRM (social customer relationship management) software, such as SAP C4C, Microsoft Dynamics, Sage CRM and Salesforce CRM. Many universities now focus, at Masters level, on engagement strategies for influencers.
In order to engage customers, retailers must shift from a linear marketing approach of one-way communication to a value exchange model of mutual dialogue and benefit-sharing between provider and consumer.[21] Exchanges are more non-linear, free flowing, and both one-to-many or one-on-one.[5] The spread of information and awareness can occur across numerous channels, such as the blogosphere, YouTube, Facebook, Instagram, Snapchat, Pinterest, and a variety of other platforms. Online communities and social networks allow individuals to easily create content and publicly publish their opinions, experiences, and thoughts and feelings about many topics and products, hyper-accelerating the diffusion of information.[22]

In fact, digital marketing now extends to non-Internet channels that provide digital media, such as mobile phones (SMS and MMS), callback, and on-hold mobile ring tones.[7] In essence, this extension to non-Internet channels helps to differentiate digital marketing from online marketing, another catch-all term for the marketing methods mentioned above, which strictly occur online.
Una guía completísima y útil Frank. El asunto “publicidad frente a afiliación” es bastante interesante, sobre todo porque la publi convencional en Internet parece que ha tocado casi fondo. De hecho hasta el New York Times se interesa ahora por los enlaces de afiliados como via de diversificar ingresos y ha comprado una web que se dedica precisamente a eso, a revisar productos y obtener comisiones de Amazon, como modelo de negocio.
