Digital marketing statistics for 2026 describe a market that keeps growing faster than the economies around it while the tools for measuring it fall short. UK advertisers spent £21.2bn on digital advertising in the first half of 2026, up 13% on the year (IAB UK and mediasense, Digital Adspend H1 2026, Sep 2026), and global internet traffic grew 19% in 2025 (Cloudflare, Radar 2025 Year in Review, Dec 2025).
This page stays at the cross-channel level: how budgets split across channels, how people use devices and shops online, how programmatic and connected TV are traded, and how much of it marketers can measure. Single-channel detail sits on the pages for SEO, PPC, email, social media, content and affiliate marketing. Every figure links to the organisation that produced it: statistics offices, regulators, company filings, trade bodies and named research datasets. Surveys and vendor datasets are labelled as such, and the page is refreshed every month.

Who is online, on which devices, and what do people do there?
Nearly everyone in rich markets is online and the phone is the first device. Attention is spread across messaging, email, social, video and audio, so no single channel reaches everyone.

How many people are online, and on what devices?
Most people in the US and EU are online and nearly all carry a phone. How much traffic mobile carries depends on who measures it: some datasets put it above half and others below.
- 96% of US adults say they use the internet, and 78% subscribe to broadband at home (Pew Research Center, Internet and Broadband Fact Sheet, Nov 2025).

- Chrome carried two-thirds of Cloudflare's request traffic in 2025 and Safari 15.4% (Cloudflare, Radar 2025 Year in Review, Dec 2025).
How much time and money do mobile apps absorb?
More every year, even though new downloads have almost stopped growing. Time and revenue rise because existing users do more in apps.
- App downloads edged up 0.8% to nearly 150 billion in 2025, while in-app purchase revenue grew 10.6% to $167 billion (Sensor Tower, State of Mobile 2026, Jan 2026).

How much buying happens online, and who sells there?
Online buying keeps taking share from stores, at a steady pace, and a few peak days stand out each year. Most businesses that sell online still lead with their own website.

What share of retail sales is now online?
It depends on the country. Great Britain is well ahead of the US and Canada, though each statistics office defines online sales slightly differently, and the US share climbs in the fourth quarter.

How big are the peak online shopping days?
Big enough to stand out in the annual totals. The 2025 US holiday season set records on spend, single-day totals and instalment payments.

Mostly through their own websites, with marketplaces as the second route. E-sales are still a minority of turnover for the average EU business.

Which channels bring in orders, and how well do online stores convert?
More traffic does not mean more orders. Shoppers move between search, social, marketplaces, partners and stores before they buy, and the mix is shifting toward social, partner and AI channels.

Which channels are gaining and losing shoppers in a multi channel journey?
Social, affiliates and new AI channels are gaining. Brand-owned properties, traditional search and marketplaces are losing ground with shoppers.
- Social media drove 29% more e-commerce visits in the second quarter of 2026 than a year earlier (Salesforce, 2026 Holiday Predictions, Jul 2026).

- From January to August 2026, compared with the same months of 2025, affiliates and partners and social networks gained the most US online revenue share, paid search gained modestly and natural search lost share (Adobe Digital Insights, 2026 Holiday Shopping Trends Forecast, Aug 2026).
- Using search engines, TV ads and social ads together would still introduce a brand to only 62.2% of the world's online adults (DataReportal, Digital 2026 Global Overview Report, data from GWI, Oct 2025).
Where do shoppers choose to buy?
Many still prefer stores, but they research on their phones and online first, so the store is the last step of a digital journey.
- For holiday shopping, 77% of consumers favor physical stores, 69% online marketplaces, 36% brand websites and 30% retailer websites (Salesforce, 2026 Holiday Predictions, Jul 2026).
- 42% of consumers visit a store specifically to buy something they researched online, and 79% are on their phones while walking the aisles (Salesforce, 2026 Holiday Predictions, Jul 2026).

How big are programmatic, connected TV advertising and retail media?
In the UK, programmatic is no longer a separate channel; it is how most digital ads are bought, and its weak point is quality rather than access. On the supply side, connected TV is where growth sits.

Which programmatic and video formats are growing fastest?
Retail media and video lead growth, with connected TV driving most of the video gain.
- Retail media was the fastest-growing UK digital category in the first half of 2026, rising 32% to £2.0bn (IAB UK and mediasense, Digital Adspend H1 2026, Sep 2026).
- UK video ad spend rose 18% to £5.1bn in the first half of 2026, and a third of it now goes to TV+, the category IAB UK links to streaming (IAB UK and mediasense, Digital Adspend H1 2026, Sep 2026).

- Digital video revenue in Canada rose 26% to C$2.79 billion in 2025, driven by connected TV and premium streaming (IAB Canada, 2025 Internet Ad Revenue Survey and 2026/27 Forecast, Jun 2026).
How much programmatic spend reaches real people?
Under the ANA's measure, most programmatic spend still does not end up as a measurable, viewable, fraud-free impression on a site that is not made for advertising.
- The share of programmatic spend reaching measurable, viewable, fraud-free and non-MFA impressions, the ANA's TrueAdSpend Index, was 43.3% across the market in the first quarter of 2026 (ANA, Programmatic Transparency Benchmark Q1 2026, May 2026).

Unevenly. Connected TV sellers grew quickly while buy-side and retail media vendors reported slow or falling quarters.
- The Trade Desk's revenue rose 3% to $715.1 million in the second quarter of 2026, as new clients added spend and existing clients spent less (The Trade Desk, Form 10-Q for the quarter ended June 2026, Aug 2026).

- IAB Canada's new measurement of ad technology and data products revealed an additional C$1.29 billion in revenue (IAB Canada, 2025 Internet Ad Revenue Survey and 2026/27 Forecast, Jun 2026).
How well can marketers measure digital marketing ROI under privacy rules?
Most marketers use at least one advanced measurement method, a minority use all three, and most say the methods fall short. The tracking layer underneath is being cut back by regulators and browsers.

Which measurement methods do marketers use, and how well do they work?
Most buyers use incrementality tests, attribution analysis or marketing mix models, but most also say the methods fall short of what they need.
- Only 39% of those buyers use incrementality, attribution and marketing mix models together (IAB and BWG Strategy, State of Data 2026, Feb 2026).
- Even digital display, the best-covered channel in marketing mix models, is called underrepresented by 31% of users (IAB and BWG Strategy, State of Data 2026, Feb 2026).

- 33.02% of EU enterprises ran data analytics with their own employees in 2025 and 13.85% used an outside provider, which together covered 39.85% of enterprises (Eurostat, Digital economy and society statistics, enterprises, Jan 2026).

Methodology and Sources
We collected these figures between 13 and 14 October 2026 and fetched every link on the day to confirm that it loads, carries the number and shows its date. Each number comes from the organisation that produced it: statistics offices (US Census Bureau, ONS, Statistics Canada, Eurostat, ITU), regulators (CNIL), company filings (The Trade Desk, Magnite, Criteo), trade bodies (IAB UK, IAB Canada, IAB Australia, ANA, IAB), platform and infrastructure reports (Google, Cloudflare, Ericsson, Sensor Tower, HTTP Archive) and named research datasets (Salesforce, Adobe, Littledata, Nielsen, Edison Research, Pew Research Center, DataReportal with GWI). Surveys are labelled with who ran them and where the sample is known. Forecasts are named as forecasts. Currency figures keep the currency of the source. Single-channel statistics are left to the dedicated pages linked in the introduction. The page is refreshed monthly.
