The pressure to prove marketing effectiveness continues to grow, particularly as budgets face greater scrutiny. Across industries, ROI is the metric that boards and budget-holders care most about—yet achieving and measuring it accurately remains a challenge.
Recent studies suggest that the average digital marketing ROI sits between 3:1 and 5:1, depending on the channel. However, this varies widely:
-
Email marketing: Still among the highest, with average ROI exceeding £36 for every £1 spent.
-
PPC (Pay-Per-Click): Typically achieves between £2 to £4 per £1 spent, depending on industry and campaign structure.
-
SEO: Offers a slower burn but delivers high long-term ROI—averaging 5:1 or higher over a 12-month cycle.
To maximise ROI, successful marketers are leaning into multi-touch attribution models, LTV (lifetime value) forecasting, and campaign-level profitability tracking. Understanding not just if a campaign worked, but why, is now central to strategic planning.
Performance Benchmarks: What’s Normal in 2024?
Knowing how your campaigns compare to industry benchmarks can help highlight opportunities or inefficiencies. Here are a few current averages across core digital channels:

These figures are just a guide, of course—what’s most important is how your own metrics track over time, and how efficiently you’re achieving your campaign goals.
Emerging Trends Impacting Performance
A few macro trends are influencing digital performance this year:
-
AI-Powered Content & Automation: Tools like ChatGPT, Jasper, and Adobe Firefly are streamlining content creation, but brands must balance automation with originality to avoid penalties or engagement drop-offs.
-
Privacy & Data Regulation: GA4 adoption, cookie consent frameworks, and user data transparency are shaping how data is tracked, reported, and leveraged.
-
Multi-Channel Attribution: With user journeys becoming more fragmented, last-click attribution is giving way to more sophisticated models that reward top-of-funnel and mid-funnel touchpoints.
Marketers are investing more in data platforms and BI tools to visualise and analyse performance in real-time, empowering agile decision-making across departments.
What Should Marketers Focus On Now?
To stay competitive, digital marketers should prioritise:
-
Performance measurement maturity: Move beyond vanity metrics to business-aligned KPIs.
-
Budget agility: Be ready to shift spend quickly based on campaign performance and external factors.
-
First-party data strategies: Build stronger direct customer relationships through CRM integration, email opt-ins, and owned content.
-
Conversion rate optimisation (CRO): Enhance on-site experience and improve the value of each visit or click.
In Summary
Digital marketing success in 2024 hinges on performance. By tracking the right benchmarks, understanding ROI at every level, and responding to emerging trends with agility, brands can ensure their digital strategy is not just visible—but profitable.
