The bottom line of digital marketing is basic:

•   Get before the right audience
•   Potential customers' attraction
•   Selling more and building brand awareness.

Types of Digital Marketing

   There are many types of digital marketing. Each type has a unique role in growing a brand online. The important ones include the following:

1. Search Engine Optimization (SEO)

SEO involves the process of optimizing a website to achieve an excellent result in search engines like Google. When a website is on page one of Google, it automatically receives more visitors.

Key benefits of SEO:

•  Free organic traffic

2. Social Media Marketing

Social media marketing utilizes outlets such as:

• Instagram
• Facebook
• Twitter (X)
• LinkedIn
