10 key components of digital marketing

Did you know?

Digital marketing has the highest return on investment (ROI) of all marketing channels. According to various studies, companies that focus more on digital marketing tend to see an ROI anywhere from 38% to over 600% higher than those relying more on traditional marketing methods alone. 

1. Search Engine Optimization (SEO)

The most crucial component of digital marketing is SEO or Search Engine Optimisation. It is the foundation of your digital marketing efforts. If you are wondering how SEO can help, it improves your organic search visibility, making your brand appear at the top in the SERP (Search Engine Results Pages) for relevant searches. 

This is done through keyword research, technical website optimisation, creating search-friendly content, and link building. With SEO, you can drive organic traffic to your website, directing to lead generation, conversions, and sales. 

2. Pay-Per-Click (PPC) Advertising

We are sure you have seen ads displayed on search engines and other online platforms. When you click them, it takes you to a different page. Those ads are paid-per-click, i.e., PPC advertising. This is because the brand (the advertisers) that put up the ad pays only when someone clicks on it. For example, Google Ads and Microsoft Ads

The right and potential customers will click on the ad because they are interested. This way, you can reach your relevant audience much faster because you can target users based on their search intent and other attributes. You can also test campaigns time-to-time to optimise them for higher conversion rates. 

3. Social Media Marketing

Social media is another vital marketing channel to establish your brand presence because of its high user base. When you post engaging content (posts, videos, etc.), run ads, and interact with your audiences, it can induce an increase in your website’s visitors, thus boosting leads and sales. 

You can find your target niche groups on top platforms like Facebook, Instagram, LinkedIn, Twitter, YouTube and Pinterest and develop social engagement through content sharing. 

4. Email Marketing

If you are thinking email marketing is still effective, yes, it is, indeed! Despite the growth of newer channels, email marketing continues to remain highly efficient for customer retention and loyalty. You can regularly engage with your customers through email subscription lists by giving promotions, valuable content, product updates, and much more. 

Do you know that emails have higher open and click-through rates than other digital channels? Yes, you heard it right! For leads nurturing and guiding subscribers down the sales funnel, you can automate drip email campaigns. 

5. Content Marketing

Down the lane, what do you hardly expect from any sort of marketing? To attract and retain customers to sell your products and services? Yes! Content marketing helps amazingly by focusing on creating and distributing valuable, relevant and engaging content, consistently to do this job. It subtly highlights your brand’s expertise instead of explicitly promoting it. 

The answer is anything if you are wondering what the content form can be. From blogs, videos, podcasts, ebooks and case studies to how-to guides, they are all effective. All you need to do is share your content across digital channels to increase visibility and website traffic, generate leads and drive sales. 

6. Display Advertising

Whenever you open a website, app or social media platform, you see visual ads. They are referred to as display advertising. It could be image ads, video ads, rich text ads, native ads and more in standard formats like banner ads.

As a brand, you can target your ads to relevant audiences as they browse websites and apps related to your services or products (offerings). Based on their on-site behaviour using cookies, retargeting helps reconnect with visitors who left your site without converting. 

7. Affiliate Marketing

If you are wondering what affiliate marketing is, it is nothing but offering rewards to external websites and influencers for promoting your brand. When the referred users purchase from the buyer, the affiiates will earn a commission.  

Nowadays, influencers are a big part of marketing since they have a huge following base and are in the power to influence people. Affiliate marketing is an efficient customer acquisition method. All you have to do is pay the affiliates the agreed cost for promoting your products or services. 

8. Website Optimisation

Potential customers will first reach your website whenever you promote your products and services to check for credibility. It is the digital hub for all marketing campaigns to drive traffic towards.  Hence, you should optimise and design your website in such a way that it provides a smooth user experience. 

Look out for website copy, layout, loading speed, mobile version and visual content to every aspect that impacts conversion rates. You should ensure clear CTAs, easy navigation, mobile responsiveness, a seamless checkout process and more when optimising the website. 

9. Inbound Marketing

Using SEO, content creation, social media marketing and email marketing to earn the attention and trust of potential customers by solving their problems is inbound marketing. It focuses more on creating valuable and relevant content to attract customers than traditional interruptive methods. 

Through inbound marketing, you can attract qualified traffic to your site, convert visitors to leads by capturing contacts, and nurture leads into customers with targeted content. 

10. Analytics and Measurement

As we have come to the end of the vital digital marketing components, let’s finish with a crucial one. Our final piece of advice for an effective digital marketing strategy is regular analytics and measurement of key metrics.
