Online marketing encompasses a wide range of strategies designed to reach customers through internet-based channels, including these five essential types:

SEO (Search Engine Optimization): involves optimizing a brand's online content to appear as a top result for specific keyword searches. By optimizing a company's website and content for search engines, the brand can increase visibility in organic search results.

Content Marketing: focuses on creating and sharing valuable, relevant, and consistent content to attract and engage a defined audience in order to increase brand awareness, customer engagement, and sales.

Email Marketing: involves sending promotional messages to people who have signed up to receive them, which can include newsletters, updates, discounts, and more.

Pay-per-click (PPC): is an online marketing model where advertisers purchase visits to their company's site instead of earning them organically. Google AdWords is the most popular PPC platform.

Social media: platforms are used to connect with audiences, build brands, boost sales, and drive website traffic. Publish great content, engage with followers, analyze results, and run social media ads.

Each online marketing type has unique strengths and can be used to achieve specific goals.
