Types of Digital Marketing: Which Channel Makes Sense for Your Business

Digital marketing is promoting a business online: through search engines, social networks, email, video, ads and messages on the phone. There are many types, but no business has to use them all. What matters is understanding what each channel brings, how fast and at what cost, and then choosing one or two that fit your audience.

1. Search engine optimization (SEO)

SEO means adapting a website and its content so that it appears in the unpaid (organic) search results on Google and other search engines. People who find you this way are already looking for what you offer, so this kind of traffic is usually the most valuable.

• Who it's for: almost every website, especially services and products people actively search for.
• Speed: slow – the first results usually come after a few months.
• Cost: no pay-per-click; you invest time or an expert's work.
• Measuring: Google Search Console – impressions, clicks and positions.

The result lasts: a well-written, well-built page keeps bringing visits even after you stop investing. Read more in the article on search engine optimization.

2. Search advertising (Google Ads, PPC)

Paid ads appear above or below the organic results, labeled “Sponsored”. The best-known platform is Google Ads (formerly Google AdWords), and there is also Microsoft Advertising for Bing. You usually pay per click (PPC – pay per click), and the ad is shown only for the keywords, locations and times you choose.

• Who it's for: when you need visits right away – a new business, a seasonal offer, a sale.
• Speed: immediate, as soon as the campaign starts.
• Cost: you pay for every click; visits stop as soon as you stop paying.
• Measuring: cost per click and, more importantly, cost per inquiry or order.

SEO and ads complement each other well: ads bring visits until SEO starts delivering, and ad data shows which keywords actually bring customers.

3. Social media marketing

Facebook, Instagram, LinkedIn, TikTok, X (Twitter) and other networks are used to publish content, talk with your audience and run paid ads. Organic posts build recognition and trust, but their reach is small on most networks, so paid ads, which can target people precisely by interests, age and location, are used for wider reach.

• Who it's for: products and services for consumers (B2C), and LinkedIn for business services (B2B).
• Speed: ads immediately, organic reach slowly.
• Cost: time for regular posts and a budget for ads.
• Measuring: reach and engagement are useful, but the real indicators are website visits and inquiries.

Choose the networks where your audience is, not all of them. One network you keep up regularly is worth more than five abandoned profiles.

4. Content marketing

Content marketing is publishing useful content – articles, guides, examples, calculators, videos – that answers your audience's questions. It doesn't sell directly; it builds trust and shows expertise, and the customer later remembers who helped them.

• Who it's for: services and products that customers research before deciding.
• Speed: slow, but the results add up over time.
• Cost: time for writing or paid writers.
• Measuring: visits to articles, reading time, inquiries coming from those pages.

Content marketing and SEO are closely linked: a text that covers its topic well ranks naturally. How keywords keep a text on topic without repetition is explained in the article on keyword density.

5. Email marketing

Email marketing is sending messages to people who signed up to your list themselves: newsletters, new product announcements, sales, reminders. Although it is one of the oldest channels, it is still among the most cost-effective, because you are talking to people who already know you.

• Who it's for: anyone with existing customers or visitors they want to bring back.
• Speed: fast once the list exists; the list itself grows slowly.
• Cost: low – tools such as Mailchimp, Brevo or WordPress plugins.
• Measuring: opens, clicks, unsubscribes and sales from the campaign.

Only send to people who have agreed. Bought address lists break data protection rules and lead to your messages ending up in spam.

6. Display advertising and remarketing

Display ads are banners, images and video ads on other websites and in apps. With Google they are shown through Google Ads (the Google Display Network), on sites whose owners earn from showing those ads through the Google AdSense program. Ad space can also be bought directly from larger portals and niche sites.

The most useful form is remarketing: ads shown to people who have already visited your site, to remind them to come back.

• Who it's for: brand awareness and bringing visitors back.
• Speed: immediate.
• Cost: per impression or click; clicks are usually cheaper, but visitors are less ready to buy than those from search.
• Measuring: conversions, not just the number of impressions.

7. Video marketing

Video is one of the most watched forms of content today: YouTube as the second largest search engine, and short video formats on TikTok, Instagram Reels and YouTube Shorts. Video can explain a product, show how something is done or introduce the people behind a business.

• Who it's for: products that need to be shown, tutorials, services where trust in people matters.
• Speed: short video can reach many people quickly, but rarely predictably.
• Cost: time for filming and editing; expensive equipment isn't required.
• Measuring: views, watch time and website visits from the video.

8. Local marketing (Google Business Profile)

For businesses that operate in a specific place – shops, repair services, restaurants, clinics – the most important free channel is the Google Business Profile. It appears in Google Maps and in local search results, with the address, opening hours, photos and reviews.

• Who it's for: anyone with customers in their city or region.
• Speed: relatively fast once the profile is complete and verified.
• Cost: free, plus time for updates and replying to reviews.
• Measuring: calls, direction requests and website visits from the profile.

9. Messaging and mobile marketing (SMS, WhatsApp, Viber, push)

Messages on the phone have a high open rate, because people read them right away. Besides SMS, messaging apps such as WhatsApp and Viber are used for business messages and communities, depending on which is popular in your market. Apps and websites can also send push notifications about new content or offers.

• Who it's for: existing customers – reminders, confirmations, short promotions.
• Speed: immediate.
• Cost: per message or per platform.
• Measuring: clicks and purchases from messages.

As with email, only message people who have agreed, and not too often – an annoying message on the phone is the fastest way to an unsubscribe.

10. Affiliate and influencer marketing

Affiliate marketing means others promote your product or service, and you pay them a commission only when they bring a customer. The best-known example is Amazon Associates, and many hosting companies, software services and online shops have their own affiliate programs. The advantage is that you pay only for results; the drawback is that the program needs monitoring and clear rules.

Influencer marketing is working with people who have an audience on social networks or YouTube. The best results usually come from smaller creators close to your topic, whose audience trusts them. Paid collaborations must be clearly disclosed.

The website and landing pages

All these channels eventually lead the visitor to one place: your website or a dedicated landing page built for a specific campaign. If that page is slow, doesn't work well on phones or doesn't clearly say what you offer and what the visitor should do next, the money and effort invested in the channels are lost.

A good landing page has a clear headline that matches the ad or post, a short explanation of the offer, proof (examples, reviews, prices) and one visible button for the next step. That is why a well-built website is the foundation of all digital marketing, not one of the channels.

Channel comparison

How do you choose channels for your business?

1. Start with the website. Fast, clear and mobile-friendly – it is where all the other channels lead.
2. Set up the free and lasting foundation: SEO for your main services or products and, if you work locally, a Google Business Profile.
3. Pick one or two additional channels based on where your audience is and how quickly you need results: search ads for quick inquiries, social media or video for products that need to be shown, email for existing customers.
4. Measure what brings business – inquiries, calls and orders – not just likes and impressions. Replace a channel that doesn't deliver after a reasonable time.
