Digital marketing refers to the use of digital channels and tools to promote products and services. Some examples of digital marketing include:

1. Search engine optimization (SEO): This involves optimizing a website or landing page to rank higher in search engine results pages (SERPs) for targeted keywords. This can be done through on-page optimization (making changes to the actual website) or off-page optimization (building backlinks from other websites).

2. Pay-per-click (PPC) advertising: This is a form of online advertising where advertisers pay a fee each time one of their ads is clicked. Google AdWords is a popular platform for PPC advertising.

3. Social media marketing: This involves using social media platforms, such as Facebook, Twitter, and Instagram, to promote products and engage with customers.

4. Email marketing: This involves sending marketing messages to a list of subscribers via email.

5. Content marketing: This involves creating and sharing valuable, relevant, and consistent content to attract and retain a clearly defined audience. The goal is to drive profitable customer action.

6. Influencer marketing: This involves partnering with social media influencers to promote a brand's products or services.

These are just a few examples of digital marketing. There are many other tactics and channels that can be used as part of a comprehensive digital marketing strategy.
