Introduction
Hello and welcome to TheNextDigital’s guide to Digital Marketing in 2025! If you’re an inquisitive newcomer, a small business wanting to grow your brand, or just looking for a new direction in your career, this guide covers all the key areas of digital marketing — in plain, real-life, human language.

1. What is Digital Marketing?

Digital marketing is the process of promoting anything — a service, product, brand, or even yourself — using the internet and digital resources. From the ad on your favorite YouTube video to the emails you receive from online shops, it’s all part of the digital marketing universe.

Example:

You open a handcrafted skincare business. Rather than just having friends or using local retailers, you open up a website, create reels on Instagram, spend some money on focused advertising, and send out informative skincare tips through email. That’s digital marketing in action.

2. Why Digital Marketing Matters in 2025

Let’s be honest — people spend hours online. Whether it’s researching products, watching videos, reading reviews, or just scrolling, your customers are already online. If you’re not there, you’re missing out.

People trust brands they find online
Most buying decisions start with a Google search
Mobile-first is no longer optional — it’s a must
Digital marketing puts your business where your audience already is.

Email is one of the most powerful tools when done right. It’s personal, direct, and effective.

Steps:

Offer something valuable to get people to subscribe
Use simple tools like Mailchimp

Fast results? PPC is the ticket.

Where to advertise:

Instagram and Facebook
YouTube
LinkedIn (B2B)
What to keep in mind: Always test varying versions of your ad. Begin small, then scale up what is successful.

11. Influencer & Affiliate Marketing

Collaborating with creators who already have the trust of your audience is a good call.

Why it works:

It’s personal, not an ad
It establishes brand credibility
It reaches warm, active communities
Starter Tip: Instead of approaching big influencers, contact micro-influencers — they are likely to have stronger engagement and are cheaper.
