Digital marketing is the process of promoting and selling products and services by electronic devices through social media, search engines, e-mail and mobile applications.

About digital marketing it depends on online marketing and offline marketing that is built on seven main pillars:

1. Content Marketing

2. Search Engine Optimization (SEO)

3. Social Media Marketing (SMM)

4. Affiliate Marketing

5. Using Search Engine Marketing (SEM)

6. Email Marketing

7. Pay-per-click (PPC) advertising

In this article, we will highlight The offline marketing:

Offline marketing is based on four main categories, which are electronic marketing( enhanced offline marketing), radio marketing, television marketing and telemarketing, and we will address each of them separately.

Electronic Marketing(Enhanced Offline Marketing):

The billboard is one of the means of marketing that is not connected to the Internet, especially electronic ones. However, the success of advertising in this way depends mainly on the placement of the billboard, as it is placed in a place crowded with pedestrians that attracts a larger number of customers, which returns to the advertiser with more positive results.

The detailed explanation through pictures and illustrations, which attracts a good number of pioneers in electronic stores, is an important factor in the digital marketing plan.

From the above, we conclude that the success of offline marketing depends on attracting the largest segment of people.

TV Marketing:

According to statistics related to television marketing, the number of television viewers in the United States is still consolidating the mass base on which television marketing is based, especially the high percentage of subscribers to multicast channels.

Radio Marketing:

A study says that in recent years, the number of radio listeners in the United States has increased significantly, and in return, the value of spending on radio advertising is rising in parallel with that rise.

And the methods of advertising on the radio developed by making the host of the program start his radio program by reciting your advertisement and promoting your product.

So, with the help of search engines, you must choose the stations whose interests and requirements are in line with your advertised products. For example, if you own a sportswear and equipment company, you need to search for a radio program whose listeners are youth and athletes, on the one hand, and on the other hand. As a radio advertiser, you must choose the advertisement that is entertaining and not boring for the listener in the absence of the visual effect that people are more attracted to.

Mobile Marketing:

The number of people connected to the Internet from smart phones has increased by much more than the number of Internet users from computers. This wide spread of smart devices has contributed to raising the value of the amounts spent on mobile advertising compared to desktop advertising expenditures.

Call and text:

It depends on contacting a person and trying to sell a product to him, but this method has limited effectiveness compared to marketing through social media.

And text messages have a better role in the marketing process due to their availability on all phones and their widespread spread. Offering discounts is an important factor for any advertiser to attract the largest segment of customers. On the other hand, you can send special offers and gifts to customers participating in text messages. The text message service allows you to remind customers of appointments. Specific to launch a specific product and determine the date of receipt, for example.

Finally:

Despite the great reliance on the Internet in the development of the marketing process that cannot be dispensed with for any advertiser, the use of traditional methods that do not need to connect to the Internet still exists and achieves good results in marketing and contributes to expanding the circle of potential customers as well as working on the development of traditional devices to achieve maximum benefit of digital media.
