Digital marketing, sometimes called internet marketing, is any marketing that reaches people through digital channels. Search engines, websites, social platforms, email, apps, video, messaging. If a customer encounters your business through a screen, that is digital marketing.
The term covers a lot of ground, which is why it often gets discussed vaguely. This guide breaks it into its actual component disciplines, explains what each one is for, and — more usefully — explains how to tell which ones your business needs.
The one distinction that matters most
Before the individual channels, there is a split that runs through all of them: organic versus paid.
Organic means you attract people without paying for the placement. You invest time, skill and content instead of media budget. Slow to build, and it keeps working after you stop.
Paid means you buy the attention directly. Fast, predictable, measurable, and it stops the moment the budget stops.
These are not competing philosophies and it is a mistake to treat them as such. Most channels support both, and most effective strategies use both: paid to generate results now, organic to reduce what you need to pay for later.
The types of digital marketing
1. Search engine optimisation (SEO)
Organic. Making your website appear in search results without paying for the position.
SEO reaches people at the exact moment they are looking for what you offer, which makes it one of the highest-intent channels available. The trade-off is time, since results typically take months, not weeks.
It breaks into on-page work (content and structure), off-page work (links and reputation) and technical work (speed, crawlability, structured data). Our introduction to SEO covers this in full, including how AI-generated search results have changed the calculation.
2. Pay-per-click advertising (PPC)
Paid. You bid for placement and pay when someone clicks.
The main platforms are Google Ads, Microsoft Advertising (Bing), and the ad systems inside Meta, LinkedIn and TikTok.
Search ads specifically are the closest thing in marketing to buying demand on demand. Someone types a query, you appear, you pay for the click. That immediacy is why PPC is usually the right first channel for a business that needs revenue this quarter rather than next year.
3. Social media marketing
Both. Building an audience on social platforms, and advertising to audiences on them.
The honest position on organic social in 2026 is that reach is hard to come by without either paid support or unusually good content. It rewards consistency and personality more than most channels, and punishes half-effort more visibly.
One development worth noting: public posts from professional Instagram accounts are now indexed by Google, which means social content and search content are no longer entirely separate concerns. We cover what Instagram indexing actually changed in a separate post.
4. Content marketing
Mostly organic. Creating material that attracts and retains an audience — articles, guides, videos, podcasts, tools, newsletters.
Content marketing is less a separate channel than the fuel for several others. SEO needs content to rank. Social needs content to post. Email needs content worth opening.
The bar has risen sharply. Generic content is now free to produce at unlimited scale, which means generic content is worth roughly what it costs. What still works is content carrying something only you have: original data, real client experience, a genuine point of view.
5. Email marketing
Mostly organic. Communicating directly with people who have given you permission to contact them.
Email is unfashionable and consistently among the best-performing channels available. The reason is structural: you own the list. No algorithm change can take your subscribers away, which is not true of any social platform or search engine.
For any business whose visibility depends on platforms it does not control, building an email list is the single most effective form of insurance.
6. Affiliate marketing
Paid, on performance. Other people promote your product and earn a commission on sales they generate.
The appeal is that you pay only for results. The catch is that you have limited control over how your brand gets represented, and affiliate programmes need active management to avoid attracting partners who damage more than they sell.
7. Influencer marketing
Paid. Partnering with people who already have the audience you want, either for a fixed fee or on commission.
Frequently confused with affiliate marketing. The difference is that affiliates are paid for outcomes while influencers are usually paid for access, whether or not anything sells.
Audience fit matters far more than audience size. A creator with 5,000 engaged followers in your exact niche will typically outperform one with 500,000 general followers, at a fraction of the cost.
8. Video marketing
Both. YouTube, short-form video, and video advertising across platforms.
YouTube is worth treating as a search engine in its own right rather than a social platform, because a large share of its traffic comes from people actively searching for something. Our guide to YouTube ad formats covers the paid side.
9. Local SEO
Mostly organic. Appearing in map results and local searches, primarily through Google Business Profile.
For any business with a physical location or service area, this is usually the highest-return work available and it is routinely neglected. A properly completed Business Profile with current hours, real photos and active review management often outperforms a great deal of more sophisticated marketing.
Which of these do you actually need?
Almost nobody needs all nine. The useful question is what your business looks like:
| If you are… | Start with |
|---|---|
| A local service business | Local SEO and Google Business Profile, then search ads |
| An ecommerce store | Paid social and shopping ads, then SEO and email |
| A B2B or professional services firm | SEO and content, then LinkedIn and email |
| A personal brand or creator | Content and one social platform, then email |
| Pre-revenue and testing an idea | Paid ads, the fastest way to find out if anyone wants it |
The most common mistake among small businesses is spreading a limited budget across five channels and doing none of them well enough to learn anything. One channel done properly will teach you more than five done thinly.
How the channels fit together
Treating these as separate silos is where most strategies fall down. In practice they compound:
- Content feeds SEO, social and email simultaneously
- Paid ads produce data on which messages work, which improves your organic content
- SEO builds the brand awareness that makes paid ads convert better
- Every channel should be feeding your email list, because that is the only audience you own
If you want to see how different industries actually deploy these, our post on who uses digital marketing looks at the patterns across sectors.
Common questions
What are the main types of digital marketing?
The commonly recognised types are search engine optimisation, pay-per-click advertising, social media marketing, content marketing, email marketing, affiliate marketing, influencer marketing, video marketing and local SEO.
Which type should a small business start with?
It depends on how customers find you. Local service businesses should start with local SEO and Google Business Profile. Ecommerce usually starts with paid ads. B2B firms tend to get more from content and SEO. Choose one and do it properly rather than attempting several.
What is the difference between organic and paid digital marketing?
Organic means attracting people without paying for placement, investing time and content instead. Paid means buying attention directly. Organic builds slowly and continues working after you stop; paid produces immediate results that end when the budget does.
Is email marketing still effective?
Yes, and it consistently outperforms its reputation. The structural advantage is ownership: your subscriber list cannot be taken away by an algorithm change, which is not true of any social platform or search engine.
