The Importance of Digital Marketing in Today's World

How people find and research products, as well as buy products has changed dramatically. Today, customers are online first, continually doing things like searching on Google, scrolling through Instagram, watching product reviews on YouTube, and purchasing directly from social media platforms. This pivot means that digital marketing is no longer just a choice but a requirement for anyone who wants to stay relevant.

Here is why digital marketing is so extremely pertinent today:

• Immense presence online: Billions of people are on the internet each day. Businesses cannot go without connecting with this global digital audience.
• Cost effective marketing: Digital campaigns will almost always be a fraction of the cost of traditional television, print advertising, or outdoor advertising, and, therefore, affordable to anyone, including start up companies and freelancers.
• Targeting: With digital tools, instead of sending your message to everybody, you can target the people most likely to buy from you.
• Instant Results: No other forms of marketing provide the instant feedback you will receive from digital platforms, whether that’s traffic to your website, people engaging with a post on social media, or who clicked through from an ad.
• Adapting & Growing: You can adapt strategies quickly, especially in fast-moving markets, enabling businesses to remain competitive.

How Digital Marketing is Different from Traditional Marketing

Marketing has always involved engaging with the correct audience at the right moment. Today, the difference is in where that audience is investing its time. Traditional marketing uses offline formats (print ads, billboards, TV, and radio) while digital marketing uses online formats (social media, search engines, and websites).

Here are two differences: 

Reach & Access

In traditional marketing, the reach is limited to a local or regional audience. Digital marketing has a global reach with a capacity to reach specific audiences or interests.

Cost

With traditional marketing, campaigns run on TV and in print can be expensive and require large budgets. Digital marketing offers a variety of affordable options available for all budgets from free social media posts to low-cost ad placement.

Engagement

Traditional Marketing: It has a one-way communication model; an organization talks, but a customer has no opportunity to respond. Digital Marketing: It has a two-way communication model; customers can like, comment, share, and engage in real-time.

Success Measurement

Traditional Marketing: It is often difficult to measure exact results—impact is built into estimations.

Digital Marketing: Constant analytics provide accurate measurement of views, clicks, and conversions.

 Flexibility

Traditional Marketing: Once the material is published, it is difficult or impossible to change.

Digital Marketing: Campaigns can be modified immediately due to results.

In layman's terms, traditional marketing generates awareness at a high level, while digital marketing is the host of more personalized, measurable, and value-based approaches to finding and turning the right audience.
