Digital marketing: a simple definition
Digital marketing, also called online marketing, refers to all marketing strategies and actions implemented on digital media. It includes websites, search engines, social networks, emails, mobile applications, and all platforms connected to the internet.
Unlike traditional marketing, digital marketing allows for direct interaction with users, precise performance measurement, and real-time campaign adjustments. This analytical and optimization capability makes it an essential pillar of modern strategies.
Why digital marketing is essential
Consumer behavior has changed dramatically. Before buying a product or service, the majority of users conduct online research, consult reviews, compare offers, and interact with brands on social media.
Digital marketing allows businesses to be visible at the right time, on the right channel, and with the right message. It is suitable for large corporations as well as freelancers and SMEs, thanks to flexible budgets and accessible tools.
The objectives of digital marketing
Digital marketing pursues several strategic objectives:
- Increase brand visibility
- Generate qualified traffic
- Convert visitors into leads or customers
- Retaining existing customers
- Improve brand image
Each digital action is part of a coherent user journey, often called a conversion funnel.

The main levers of digital marketing
Digital marketing relies on several complementary levers. Combining them allows for sustainable and measurable results.
SEO and organic search engine optimization
SEO (Search Engine Optimization) aims to improve a website's visibility in organic search engine results. It is based on three pillars: technical aspects, content, and popularity.
Good organic search engine optimization (SEO) allows you to attract qualified traffic in the long term, without relying exclusively on paid advertising.
Online advertising (SEA)
Search Engine Advertising (SEA) encompasses paid advertising campaigns on search engines and social media platforms. It allows for quick and targeted results.
Advertisers can precisely define their audience, their budget, and measure the return on investment.
Social media marketing
Social media has become a major channel for communication and conversion. It allows you to create a close relationship with your audience and develop an engaged community.
Email marketing and automation
Email marketing remains one of the most cost-effective channels. Thanks to automation, it's possible to send personalized messages based on user behavior.
Content marketing
Content marketing involves creating high-value content to attract and retain an audience. Blog articles, videos, guides, and case studies are all formats used.
