What is Digital Marketing?
Digital marketing, also known as online marketing, encompasses marketing activities on all digital platforms such as electronic devices or the internet.
In simpler terms, any marketing campaign that takes place in a digital environment is considered digital marketing.
Why is Digital Marketing Important?
Over the years, digital marketing has become an essential part of businesses’ marketing strategies.
Compared to traditional marketing methods, digital marketing allows you to reach potential customers faster and target them more precisely. Additionally, allocating the budget for digital marketing is very flexible, allowing adjustments at various stages of the marketing campaign.
Here are some reasons why digital marketing is crucial:
The ability to target precisely results in higher conversion rates.
Think back to television ads, outdoor billboards, or magazine ads. These marketing methods make it very difficult to measure the exact number of viewers or readers. However, digital marketing works differently.
Digital marketing allows you to specifically target your audience, while providing personalized content that leads to higher conversion rates.
For example, you can use Google AdWords or SEO to reach people who are interested in your products or services by targeting specific keywords related to your field.
Or, with advertising platforms on social media like Facebook, you can target an audience based on demographics such as age, gender, location, interests, and behaviors.
The use of machine learning technology and big data analytics helps advertising platforms in the digital space accurately reach customers who are more likely to have a need for your product.

Optimized Advertising Costs
With digital marketing, you can fully customize your daily budget, and this can vary at different times. You can increase your budget if you see that the ad is performing well, or you can reduce spending if you notice the advertising channel has a low return on investment (ROI).
Fast Reach and Large Coverage
One of the great advantages of digital marketing is its incredibly fast reach. Through distribution platforms, advertising channels, and social media, businesses can disseminate their information rapidly.
For example, with just a few steps, you can send your brand message to thousands of target customers. Or, with just a few clicks, you can send emails to thousands of people on your list.
Large Coverage: Digital platforms have massive user data, gathered from user-submitted information or activity history. As a result, when running a digital marketing campaign, you can reach virtually any location around the world.
Ability to Measure Effectiveness
Digital marketing provides an easy and effective way to measure success using digital analytics tools. Through these measurement tools, you can accurately gauge customer interest through metrics such as video views, clicks, shares, website traffic, post reach, and associated costs.
In addition, digital marketing gives you real-time data, allowing you to estimate ROI through detailed reports at any time you check.
Variety of Marketing Methods
Today, businesses and individuals selling products online have many options to get started. There are numerous digital marketing formats available to support your marketing efforts, and I will outline these methods in more detail below.

- SEO (Search Engine Optimization)
- PPC (Pay-Per-Click Advertising)
- Content marketing
- Social Media Marketing
- Affiliate Marketing
- Native Advertising
- Marketing Automation
- Email Marketing
- Online PR

Below is basic information about the strategies and tactics of the most popular types of Digital marketing
1. Search Engine Optimization (SEO)
The goal of SEO is to improve the ranking of your website on search engine results pages (SERPs) to drive more organic traffic to your site. To achieve this, SEO professionals typically implement the following optimization strategies:
- On-Page SEO: This strategy focuses on optimizing the content available on the website. Through keyword research and understanding user intent behind these keywords, SEO experts aim to provide the best answers for users’ queries.
- Off-Page SEO: This method focuses on activities outside of the website itself. SEO experts primarily work on building backlinks to improve the website’s authority, which helps increase its ranking on search engine results pages.
- Technical SEO: Also known as technical search engine optimization, this method focuses on improving the user experience when accessing the website. Some key aspects of Technical SEO include improving page load speed, optimizing image sizes (image compression), enhancing structured data, and optimizing CSS files.
2. Pay-Per-Click Advertising (PPC)
PPC (Pay Per Click) is a method of attracting traffic by paying for each click on your ads. Typically, when people think of PPC, they think of Google Ads, which is a type of advertising on Google’s search engine. In addition to Google Ads, there are other platforms where you can run PPC campaigns:
- Ads on CocCoc, Bing, Yahoo: Other search engines also offer advertising platforms, though not as popular as Google Ads. These platforms still have their own customer base and can be effective for specific audiences.
- Facebook Ads: The Facebook advertising platform allows you to show ads in the form of videos, image posts, or slideshows. These ads can appear on the News Feed or other suitable placements to help you reach potential customers.
- TikTok Ads: TikTok has become a popular video-sharing social media platform, and its advertising platform helps you reach a large audience of potential customers through engaging video ads.
- Twitter Ads: Similar to Facebook, Twitter’s advertising system allows businesses to implement strategies to improve website traffic or attract more followers and interactions on Twitter.
- Sponsored Messages on LinkedIn: This form of advertising allows you to send messages directly to users on LinkedIn, offering a unique way to engage with professionals and generate leads.
3. Content Marketing
Content marketing is a form of marketing that involves storytelling and sharing useful information to raise brand awareness. The goal is to engage the audience by delivering valuable and relevant content.
To succeed in content marketing, you need to understand what your readers are looking for. What type of content will make them lose interest and leave the site, and what content will keep them engaged and spending more time on your website?
Some common content marketing strategies include:
- Blogging: Posting blog articles on your company’s website can attract a significant amount of organic traffic. This method is often combined with SEO optimization to maximize traffic.
- Video and Podcasts: Creating videos and podcasts is an excellent way to promote knowledge and showcase your brand to your target audience.
- Infographics: Infographics are visually appealing content types that engage viewers effectively. Platforms like Pinterest are popular for sharing infographics globally.
- Ebooks and Whitepapers: Ebooks and whitepapers are in-depth content pieces packed with valuable information. Websites often use these to collect contact information from readers, which can then be used to convert them into potential customers.
4. Social Media Marketing
Social media marketing is the process of creating content tailored to different social media platforms to encourage engagement and promote your business.
Commonly used social media platforms in marketing include:
- Snapchat
Social media marketing is all about connecting with your audience or customers and helping them better understand your brand. It is incredibly beneficial for the growth of your business by building relationships and fostering brand loyalty.
5. Affiliate Marketing
Affiliate marketing is the process in which an affiliate earns a commission for promoting another person’s or company’s products. The affiliate simply finds a product they like, promotes it, and earns a share of the profit for each sale they generate. Sales are tracked via affiliate links from one website to another.
In Vietnam, AccessTrade is considered a pioneer in the affiliate marketing industry.
6. Native Advertising
Native advertising, also known as contextual advertising, refers to the use of paid ads that match the look, feel, and function of the platform or medium they appear on.
Native ads are commonly found in social media feeds or as suggested content on websites. Unlike traditional display or banner ads, native ads do not appear as obvious advertisements. Instead, they blend seamlessly into the content stream, making them appear as a natural part of the editorial layout of the page.
The key to native advertising is that it is non-disruptive—allowing the audience to engage with the advertising content without feeling like they are being marketed to. This subtle approach increases user engagement as it aligns more closely with the user’s experience on the platform.
7. Marketing Automation
Marketing Automation refers to the use of software to automate marketing tasks. Many marketing departments automate repetitive tasks such as email marketing, social media posting, and even advertising campaigns. This is not only for efficiency but also to provide a more personalized experience for their customers. Marketing automation technology makes these tasks easier and more effective, helping businesses scale their marketing efforts while maintaining relevance and engagement.
8. Email Marketing
Email marketing involves sending commercial emails to “email subscribers”—those who have opted in to receive emails from you. It is used to inform, promote sales, and build a community around your brand (for example, through newsletters).
The modern approach to email marketing has moved away from spammy emails and now focuses on personalization, segmentation, and obtaining consent from recipients. It’s all about sending the right message, at the right time, to the right audience.
9. Online PR
Online PR (Public Relations) refers to managing a brand’s public image through online media channels. These channels include traditional online media outlets like e-newspapers and websites, but also extend to social media platforms, blogs, and websites.
Sometimes, online PR involves collaborating with celebrities or influencers to share information with their target audience—be it fans or followers. This approach is effective for reaching wider, more engaged audiences and enhancing the credibility of the brand.
10. Sponsored Content
Sponsored content refers to a type of advertising where the publisher or influencers on social media create content that aligns with their usual style—whether it’s an article, photo, video, or other forms of media. Brands collaborate with these publishers or influencers to co-create content that sparks conversation about their product category or even a specific product. This form of content marketing blends promotional messaging with organic, trusted media formats.
11. Inbound Marketing
Inbound marketing is the process that helps potential customers find your company. This often happens even before the customer is ready to make a purchase, but by getting noticed early, you can create a positive relationship with the brand, which may ultimately lead them to become leads and drive revenue.
Inbound marketing is a strategy that uses various marketing methods—content marketing, blogging, events, search engine optimization (SEO), social media, etc.—to build brand awareness and attract interest from the community.
Inbound marketing focuses on visibility so that potential buyers can find you. Instead of “forcing attention,” companies using inbound marketing focus on newer methods aimed at building awareness, developing relationships, and generating leads.
