Digital Marketing Services FAQs

Digital marketing refers to the use of digital technologies to promote and sell products or services. Here at Submerge, that involves reaching customers through various online platforms and digital channels such as search engines, social media networks, email, and websites. A key advantage of digital marketing over traditional methods is its ability to reach a wider audience across different regions without the geographical constraints associated with offline marketing. It also offers detailed analytics that help marketers understand customer behaviour and refine their strategies for improved effectiveness.

Digital marketing is highly customisable – our approach allows businesses to tailor their messages to specific segments of their audience for more personalised communication. This level of precision helps in creating more relevant and engaging interactions, which can lead to higher conversion rates.

Digital marketing not only includes the promotion and selling of products but also focuses on building digital experiences that support the overall customer journey, from awareness to purchase and beyond.

Digital marketing offers several compelling benefits that make it a vital part of any modern business strategy.

One of the primary advantages is its cost-effectiveness. Our digital marketing services allow businesses – especially small to medium enterprises – to reach a larger audience at a lower cost compared to traditional marketing methods like television and print advertising.

Another benefit is the ability to measure and analyze the impact of campaigns in real-time. We use tools such as Google Analytics, Google Search Console, SEOcrawl and SEMrush to keep on top of your performance. With digital marketing, you can see detailed data about how users interact with your ads and content, which helps in making informed decisions to optimise strategies and improve return on investment. This level of analytics extends to understanding customer behaviour, preferences and engagement patterns.

Digital marketing also enhances target marketing. Through digital channels, businesses can target very specific demographics, from age and location to interests and browsing behaviour. This precision enables more effective and personalized marketing, which leads to higher engagement rates.

Furthermore, digital marketing provides flexibility in terms of content and messaging. Campaigns can be tested and stopped in real-time based on their performance, allowing for rapid adjustments to maximize effectiveness. This agility is crucial in the fast-paced digital landscape.

Lastly, digital marketing helps in building customer relationships and loyalty. By engaging with customers through social media, email newsletters, and tailored content, businesses can develop a direct communication channel with their audience, fostering trust and loyalty which are critical for long-term success.

Digital marketing encompasses a wide range of strategies and channels, each serving distinct purposes and utilising different techniques to engage customers. Here are some of the key types:

Search Engine Optimisation (SEO)

This involves optimising a website to rank higher in search engine results pages, thereby increasing organic (non-paid) traffic. SEO strategies include using relevant keywords, enhancing site structure and navigation, and improving the quality of content.

Pay-Per-Click (PPC)

PPC is a method of driving traffic to a website by paying a publisher every time an ad is clicked. One of the most common forms of PPC is Google Ads, which allows businesses to appear at the top of Google search results for specific keywords.

Social Media Marketing

This practice promotes content and engages with customers on social media platforms like Facebook, X, Instagram, and LinkedIn. It’s a powerful way for businesses of all sizes to reach prospects and customers, fostering brand awareness and boosting sales.

Content Marketing

This strategic marketing approach focuses on creating and distributing valuable, relevant, and consistent content to attract and retain a clearly defined audience. The goal is to drive profitable customer action through articles, videos, podcasts, and other media.

Email Marketing

Businesses use email marketing to communicate with their audiences. Email is often used to promote content, discounts, and events, as well as to direct people toward the business’s website.

Affiliate Marketing

This is a performance-based advertising where you receive commission for promoting someone else’s products or services on your website.

Influencer Marketing

Brands collaborate with influencers who have a large following on social media to promote their products. This type of marketing can tap into the influencer’s audience and gain credibility through association.

Mobile Marketing

This includes sending SMS messages, creating mobile applications, and designing responsive websites that adapt to the size of the user’s device. This approach is critical as an increasing number of consumers access the internet on mobile devices.

Each of these types can be used independently or combined in a comprehensive, multi-channel digital marketing strategy.
