The Future of Digital Marketing: Key Trends to Watch in 2026

The short version

Digital marketing crossed a milestone in 2026. Global advertising spend is on track to pass $1 trillion for the first time, and digital now takes the majority of it. Industry forecasts put digital at roughly 68.7% of all ad spend, close to $836 billion globally, according to GroupM and eMarketer forecasts.

The money follows the audience, and the audience has moved. Search still leads the channel mix at around 31% of digital spend, with social close behind at around 26%, and both keep growing. But the bigger story is how those channels are being consumed: through AI answers, short-form video and connected retail.

None of this means the fundamentals changed. It means the environment they operate in changed. This guide covers the trends that will actually shape marketing decisions in 2026, and what to do about each one.

1. AI is the default layer now

Artificial intelligence is no longer a novelty in marketing. It is the infrastructure.

OpenAI reported ChatGPT passed 800 million weekly active users in late 2025 and 900 million by February 2026. Google serves AI Overviews on an estimated 13 billion queries a month. When the tools people ask questions of are AI systems, marketing has to be built to be found by them.

What this means in practice:

• Content has to be structured for extraction, with clear headings and self-contained answers, because AI systems pull passages, not whole pages
• Structured data matters more, because it tells AI systems what your entities are
• Being cited in AI answers is now a channel, as real as search or social
• Marketing teams use AI internally too, for drafting, analysis and personalisation, and the gap between teams that do and teams that do not is widening

The businesses winning here are not doing anything exotic. They have clean sites, clear content and visible entities. The AI systems do the rest.

2. AI search and zero-click behaviour

The way people find businesses is splitting into two paths: classic search results and AI-generated answers. The second path is where the growth is.

Perplexity, ChatGPT Search and Google's AI Overviews all write answers and cite sources. The click is optional. For the brands in the answer, that is free visibility. For the brands not in it, the research phase ends before their website ever gets a visit.

Key shifts:

• Recency matters more. AI systems favour recently updated content, so quarterly refreshes of important pages are now standard practice
• Citations correlate with organic rankings. Businesses in the top ten for a query are the ones AI systems cite, so SEO is the engine room of AI visibility
• Bing matters again, because ChatGPT Search retrieves from the Bing index

What to do about it: keep the fundamentals strong, because they feed everything. Make the pages that matter answer-first and self-contained, so an AI system can extract a clean passage. Update the important pages on a schedule. And add the technical pieces that make retrieval easy, including structured data and an llms.txt file. None of this is exotic. It is good SEO, applied to a new surface.

3. Personalisation is now expected, not nice to have

Consumers have been trained by the platforms to expect relevance. Generic messaging reads as noise, and noise gets ignored.

The personalisation that works in 2026 is not just using a first name in an email. It is:

• Messaging matched to where someone is in the buying journey
• Offers and content that reflect what the customer has already looked at
• Audience segmentation that goes beyond broad demographics
• Dynamic creative in paid media, where the ad adapts to the viewer

HubSpot's long-standing finding that personalised calls to action convert better than generic ones still holds, and the bar keeps rising. The practical point: know your customer better than your competitors do, and show it in everything you publish.

4. Short-form video and social commerce

Short-form video is the dominant content format on social platforms. Around 90% of people regularly watch short-form video on TikTok, YouTube and Facebook, according to The Global Statistics' short-form video research, and the format keeps growing.

Social media advertising is also the fastest growing major channel, with MAGNA forecasting around 14.6% growth in 2026, ahead of connected TV and retail media. The platforms that used to be about connection are now about transaction, with in-app shopping, product tags and social storefronts closing the gap between seeing and buying.

What to do:

• Short-form video as a core content format, not an occasional experiment
• Content built for the platform's native behaviour, not repurposed corporate video
• Commerce features used where your customers actually buy that way
• Consistency over virality. The brands that win on social are the ones that show up regularly, not the ones that chase one big hit

5. Retail media keeps compounding

Retail media is the fastest growing advertising category, with eMarketer forecasting growth around 14.1% in 2026. It works like this: a retailer sells ad space on its own site and app to brands that want to reach shoppers at the moment of purchase.

Amazon is the big player, but Australian retailers are building the same machinery. For brands that sell through retail, retail media budgets are becoming a significant line item, because the targeting is based on actual purchase data and the returns are directly measurable.

For service businesses and B2B, the equivalent is channel-specific advertising inside the platforms where buying decisions happen: LinkedIn for professional services, trade platforms for trades, industry publications for niche B2B. The principle transfers: advertise where the buyer is already in the process of deciding.

6. Data privacy and first-party data

Privacy stopped being a future trend and became a compliance requirement.

Australia's Privacy Act reforms, passed in 2024, commenced on 10 December 2025. They bring higher penalties, new rights for individuals and tougher obligations for how businesses handle personal information. Combined with the global decline of third-party cookies, the direction is clear: the data you can collect about your customers is getting tighter, and the data you already own is getting more valuable.

The marketing response:

• First-party data as the foundation: email lists, customer records, loyalty data, survey responses
• Consent handled properly, because the penalty for getting it wrong is now bigger
• Personalisation built on data customers gave you willingly, which tends to perform better anyway
• Analytics and tracking reviewed for compliance, not just for accuracy

The businesses that treat privacy as a trust advantage will earn more attention and more loyalty than the ones that treat it as a legal nuisance.

7. Mobile is the default, not a channel

Mobile accounts for roughly 62% of digital ad spend globally, and the share keeps climbing. For most Australian businesses, the mobile experience is the customer experience.

That means:

• Sites built mobile-first, because that is where most visitors arrive
• Speed as a conversion factor, not just a ranking factor
• Local search and local content, because mobile users are often searching with intent to visit or call
• Forms and checkout designed for thumbs and patience, meaning minimal steps

The businesses that treat mobile as the primary experience, rather than a smaller version of the desktop site, are the ones converting the traffic.

Trends that are not trends

Every year produces a batch of loudly marketed trends that turn out to be noise. The metaverse, NFTs, crypto marketing, the race to build a profile on whatever social platform just launched. A small number of businesses genuinely benefited from each of them. Most were better off ignoring them.

The test is simple: are your customers actually there, actually spending, actually deciding? If the answer is not verifiable, the trend is entertainment, not strategy.

That is not a reason to ignore new channels entirely. It is a reason to treat them as experiments with a budget and a measurement, the same way you would treat any other campaign. If a new platform shows real customer behaviour, scale it. If it is all hype, let the competitors burn their money learning the lesson for you.

How to prioritise

No business can act on all of these trends at once, and pretending otherwise is how marketing budgets die. The practical approach:

1. Start with the trend that touches your funnel most directly. For most Australian businesses that is AI search, because it is changing how customers research every category. For retailers it may be social commerce. For B2B it may be first-party data and personalisation.

2. Keep the fundamentals running while you test. SEO, content quality, tracking and speed do not change. They are the base every trend builds on.

3. Put a number on it. Decide how you will measure the experiment before you start, and give it a fixed window. If the number moves, keep going. If it does not, stop.

4. Revisit quarterly. The market moves fast, but quarterly is the right cadence for decisions that involve real budget.

The businesses that win in 2026 are not the ones chasing every trend. They are the ones that pick the two or three that matter to their customers, do them properly, and measure the result.

What this means for your business

The trends stack. AI search rewards the same fundamentals as classic SEO. Personalisation needs the same clean data that privacy compliance requires. Short-form video needs consistency, not tricks. Retail media needs the same measurement discipline as everything else.

There is no one new thing to adopt and win. There is a set of foundations that keep paying off: know your customer, measure everything, publish content worth finding, and keep the technical base clean.

If you want help applying any of this to your business, that is the work I do. The starting point is an audit of where you stand, followed by a plan that is honest about what will move the numbers.
