What is Digital Marketing?

Digital marketing is the promotion of a business, product or service through online channels, such as search engines, websites, social media, email and digital ads.

The main channels

Search engine optimization (SEO), paid search and paid social ads, social media, email, content marketing and your website itself. Each channel reaches people at a different point, from first discovering you to deciding to buy.

How it differs from traditional marketing

Digital channels can be targeted and measured in detail. You can see which ads, searches and emails led to sales and shift budget toward what works. Print, radio and billboards rarely give that level of feedback.

How big it has become

eMarketer projected that digital would make up more than 80% of total US media ad spending for the first time in 2025. For most businesses, digital is no longer one channel among many. It's where most customers find and compare options.

Why Digital Marketing matters

Customers research online before they call, visit or buy, even for local services. A business that isn't visible and convincing online loses customers to competitors that are, often without ever knowing it.

One customer, several channels

A homeowner sees a roofing company's ad on social media, later searches for roof repair and finds the same company in Google Maps, reads its reviews and books an inspection on its website. The sale came from several channels working together, not one.

Common mistakes

  • Doing every channel at once

    Spreading a small budget across every platform usually means doing none of them well. Start with the channels closest to a sale, often search and your website.

  • Measuring clicks, not customers

    Traffic, likes and impressions are easy to grow and easy to misread. Track leads, sales and cost per customer.

  • Ignoring the website

    Ads and SEO send people to your site. If it's slow or unclear, every other channel performs worse.
