Digital marketing refers to the use of digital channels and techniques, such as search engine optimization (SEO), social media, email, and websites, to promote a product or service. It differs from traditional marketing in that it utilizes the internet and digital technologies to reach and engage with a target audience.

To get started with digital marketing, small businesses should first identify their target audience and determine what their unique value proposition is. They can then create a website, establish social media accounts, and begin to publish regular, valuable content. It is also a good idea to invest in search engine optimization to help increase visibility in search engines.

Some of the most effective digital marketing strategies for small businesses include content marketing, social media advertising, email marketing, and search engine optimization. The right strategy will depend on the business's target audience, goals, and budget.

The amount that a small business should expect to spend on digital marketing will depend on your specific goals and target audience, as well as yourbudget. Some businesses may be able to achieve their goals with a small budget, while others may require a larger investment. It is important to work with a digital marketing agency that can help determine the right budget for your business and create a cost-effective digital marketing plan.
