Final: Why is Digital Marketing Important in the 21st Century

Digital marketing is a broad term that encompasses various channels and tactics. However, it typically entails harnessing digital platforms to promote products. Let’s discuss the basics of digital marketing below:

Website Design and Development

Website design and development is the foundation of your digital marketing strategy. Your website influences the majority of purchase decisions. It is what communicates your brand’s value and identity. It also creates the first impression. So, creating a functional website that delivers positive customer experiences is crucial to attracting and retaining them.

However, an excellent website starts with the design and development process. So, speed up your site by ensuring quick load time, cutting out clutter, using legible typography, and creating clear calls to action. You should also ensure a clear information hierarchy and communicate your brand’s values on your website.

Search Engine Optimization

Search Engine Optimization (SEO) involves adopting specific practices to improve your website for higher visibility on search engines. The higher your website’s visibility, the better your chances of being found on search engines by your target customers, increasing customer acquisition and retention. Therefore,  as a digital marketer, understanding SEO boosts your website’s traffic, increases your business’s exposure, and gains more customers.

SEO practices involve researching keywords, creating relevant content your audience resonates with, and optimizing your website pages with title tags, meta descriptions, and more to increase rankings on search engine results.

Pay-Per-Click Advertising

Pay-per-click, also called PPC, is a digital advertising model that requires the advertiser to pay a fee when their ads are clicked. Google Ads, Amazon advertising, and Microsoft ads promote PPC advertising. PPC advertising is based on keywords. For example, online ads appear in search engines when someone searches related keywords. So, companies adopting pay-per-click advertising adopt relevant keywords, leading to more clicks. Primarily, companies running ads are charged only when a user clicks their ad, hence, the term “Pay-per-click” advertising.

Social Media Marketing

Social media marketing is an important aspect of digital marketing because it enables businesses to build their brand, attract customers and build relationships with their customers. You can reach a wider audience just by posting an ad on Facebook, Instagram, or Twitter, enabling you to reach thousands of people needing your products or services, increasing sales. Social media platforms are also excellent for engaging with customers, responding to feedback, and showing your brand’s authenticity to build positive customer relationships.

Email Marketing

In addition, email marketing generates a higher return on investment than many marketing channels, generating about 4400% ROI. Therefore, email marketing is adopted by businesses and marketers to grow their brand.

Content Marketing

Content marketing involves creating and sharing content on digital platforms to promote, educate, inform, and entertain your audience. This could be in the form of blog posts, emails, infographics, videos, etc. An effective content marketing strategy helps you connect with your audience, communicate your brand’s value, and educate them about how your product works, its benefits, etc. As a result, effective content marketing is an excellent way to showcase your brand’s credibility, build authority, and increase customer retention.

Mobile Marketing

Hence, managing activities in-house allows businesses to save costs with digital marketing.

Increased Efficiency

Digital marketing automation tools are excellent ways to streamline your marketing activities for faster results.
