For most of the last decade, digital marketing changed in increments. Platforms updated, tactics evolved, budgets shifted – but the underlying playbook largely held.
In 2025, that playbook cracked.
Not because of one algorithm update or one new channel, but because multiple forces hit at once: Google’s results pages changed shape, AI tools reshaped how people research and decide, paid media got more expensive and less predictable, customer journeys became harder to map, measurement got messier, and budgets got tighter.
The practical impact was simple: optimising a single channel in isolation stopped being enough – not that it ever was. The winners weren’t the teams with the most tactics – they were the teams with the clearest system.
A useful way to think about the new reality is as a connected ‘Discovery System’:
➡️ Awareness: showing up where buyers start exploring (search, social, AI tools)
➡️ Consideration: building trust with proof, clarity, and genuinely useful content
➡️ Decision: capturing high-intent demand and converting it efficiently
➡️ Learning loop: measuring what matters and reallocating spend with confidence
This article is a roundup of what changed across each area in 2025 – and, more importantly, what to do about it going into 2026.

Key Takeaways:
2025 wasn’t defined by one platform change or one new tool – it was defined by how many shifts happened at once. From AI reshaping discovery, to rising media costs and more complex customer journeys, the year forced marketers to rethink how channels work together. These are the five lessons that mattered most – and will shape how teams plan for 2026.
- 2025 broke single-channel optimisation. The biggest shift was how many changes hit at once – AI in SERPs, AI discovery, rising paid costs, fragmented journeys, messier measurement, tighter budgets – making connected strategy the differentiator.
- SEO is still a growth driver, but it’s become more deliberate. Winning in organic now leans harder on authority, credibility, and decision-stage usefulness (not just rankings or volume).
- Paid performance now rewards efficiency and structure, not scale. With CPCs/CPMs up and performance more volatile, the best results come from intentional budget splits (profit protection vs growth tests), stronger conversion fundamentals, and sequenced Paid Social.
- Content shifted from “publish more” to “influence decisions” – with distribution built in. Generic content is easier to summarise and harder to justify. The winners focused on proof-led, comparison-driven, buyer-enabling content – and treated distribution as part of the strategy.
- Measurement and budgets moved from precision to confidence. Attribution got noisier, but the answer isn’t giving up – it’s triangulating data, defining channel roles, and reallocating spend based on outcomes and contribution rather than last-click metrics.
SEO: A higher bar – and a bigger differentiator
In 2025, SEO didn’t “die” – it matured. As Google rolled out AI-driven SERP features (including AI Overviews), the results page evolved from a list of links into a richer, more dynamic experience. That shift raised the bar for organic performance and pushed brands to focus less on surface-level optimisation and more on earning visibility through real relevance and trust.
With competition intensifying and SERP real estate tightening, the winners weren’t simply the brands publishing the most content – they were the ones that felt most credible. Clear expertise, strong authority signals, and content that genuinely supported decision-making became the difference between being present in search and being chosen.
What to do about it
If 2025 was the year SEO became less predictable, 2026 is the year to make it more deliberate:
- Reframe SEO success away from session volume alone. Track outcomes like qualified traffic, assisted conversions, and brand search demand.
- Prioritise decision-stage content comparisons, alternatives, “best for”, implementation, pricing expectations) instead of over-investing in informational content that’s easily summarised.
- Build authority on purpose : expert-led perspectives, clear topical ownership, strong internal linking, and credible proof (case studies, data, recognisable third-party signals).
In short: the goal is no longer just to rank. It’s to earn presence and preference in a SERP that’s increasingly designed to keep users where they are.

Paid Media: PPC and Paid Social under pressure
If 2025 taught marketers anything about paid media, it was that spend alone doesn’t guarantee performance.
Across PPC and Paid Social, costs continued to rise. CPCs and CPMs increased, auctions became more competitive, and AI-driven bidding introduced greater volatility. At the same time, leadership teams demanded clearer justification for every pound invested.
Paid Social also continued its evolution. While still capable of driving conversions, its most reliable impact increasingly came earlier in the journey – creating demand, building familiarity, and reinforcing trust rather than closing the final click.
What to do about it
To regain control of paid performance:
- Split paid budgets intentionally:
- Profit protection: high-intent PPC, brand defence, proven conversion paths
- Growth tests: controlled experimentation, new audiences, creative learning
- Pull efficiency levers before raising bids: conversion rate optimisation, landing page clarity, creative testing, query and audience hygiene.
- Use Paid Social as a system, not a series of ads – sequenced creative that builds awareness, proof, and intent over time.
Paid media in 2026 rewards teams who understand where each pound works hardest – not those who chase scale blindly.

Content Marketing: From volume to value (and distribution)
Content marketing felt the impact of 2025 more quietly than SEO or paid media – but arguably more deeply.
As AI systems became better at summarising generic information, a large proportion of “standard” blog content lost its edge. Articles written to rank – rather than to influence decisions – increasingly struggled to justify their investment. At the same time, content teams faced familiar pressure: produce more, with less time, less budget, and higher expectations.
The brands that succeeded didn’t stop investing in content. They changed what content was for.
Instead of chasing volume, they focused on content that helped buyers:
- Compare options
- Understand trade-offs
- Build confidence
- Justify decisions internally
Content became less about attracting traffic, and more about creating clarity and trust – supporting SEO, GEO, sales conversations, and paid performance all at once.
What to do about it
To make content work harder in 2026:
- Shift from publishing calendars to decision coverage: comparisons, “best for”, use cases, objections, integrations, expectations.
- Design content to support multiple channels – SEO, AI discovery, Paid Media landing pages, sales enablement – not just organic traffic.
- Build distribution into the strategy so content doesn’t rely on Google alone (email, social, partnerships, paid amplification where appropriate).
The question content teams should now ask isn’t “How often should we publish? “It’s “What decisions do we need to influence?”

GEO: Competing to be recommended in AI answers
Alongside changes in traditional search, 2025 marked a tipping point in how people discover and shortlist brands.
AI tools like ChatGPT moved beyond novelty and into everyday use – not just for information, but for evaluation. Users increasingly asked AI systems questions like:
- What’s the best option for…
- Which provider should I choose if…
- Compare X vs Y
This introduced a new competitive dynamic. Brands weren’t just trying to rank – they were trying to be recommended.
Generative Engine Optimisation (GEO) emerged as a response to this shift. Not as a replacement for SEO, but as a way to ensure brands are visible, credible, and referenceable in AI-generated answers.
What to do about it
To compete in AI-driven discovery:
- Define the prompts that matter: category definitions, use cases, comparisons, objections, “best for” scenarios.
- Create assets AI systems can trust: clear positioning, structured content, first-hand expertise, evidence (case studies, data, methodology).
- Track visibility directionally, not perfectly – prompt sampling and share-of-voice snapshots are enough to guide improvement.
The brands that win GEO don’t chase hacks. They build clarity, credibility, and consistency at scale.

Could your brand handle 60% more conversions?
That’s one result we delivered, but it’s far from the only one. From cutting wasted spend to scaling pipeline, our PPC strategies consistently drive performance for B2B brands.
Local Marketing: High-intent demand, higher expectations
Local marketing remained one of the most commercially important areas of digital – but it didn’t escape change.
Local discovery still drove action, yet users increasingly researched before converting. Reviews, proof, service clarity, and availability mattered more than ever. At the same time, Local PPC costs rose as more advertisers fought for the same high-intent queries.
The opportunity didn’t disappear – it became more competitive.
What to do about it
To win locally in 2026:
- Treat Google Business Profile as a performance asset, not a listing – keep services, posts, photos, and Q&A active and accurate.
- Build a repeatable review engine focused on volume, velocity, and meaningful sentiment.
- Align Local PPC tightly to service + location intent, and measure success via calls, leads, and bookings – not impressions alone.
Local marketing rewards consistency and proof. The basics still work – but only when done properly.

Customer Journey: Non-linear, multi-touch, AI-influenced
One of the clearest changes in 2025 wasn’t tied to a single channel – it was how customers moved between them.
Journeys became longer and less predictable. Users discovered brands via search, social, AI tools, recommendations, and content – often across multiple sessions and devices. AI increasingly supported research and comparison, even if it didn’t drive the final click.
This made traditional funnel thinking harder to apply, and last-click attribution even less reliable.
What to do about it
To plan effectively for modern journeys:
- Design around moments, not funnels: discover → evaluate → decide.
- Assign roles to channels (demand creation vs demand capture) and measure them accordingly.
- Judge performance by contribution, using blended indicators like assisted conversions, branded search lift, and pipeline influence.
Understanding the journey doesn’t require perfect data – it requires intentional structure.

Measurement: The metrics reset
As channels changed, measurement struggled to keep pace.
In 2025, attribution models weakened, platform-reported metrics diverged, and leadership teams demanded greater confidence in marketing’s impact – often with less reliable data than before.
This forced a mindset shift. The goal moved from “perfect attribution” to directional decision-making.
What to do about it
To restore confidence in performance measurement:
- Triangulate data: platform metrics, analytics, CRM, and experiments all play a role.
- Define success by channel role, not uniform KPIs.
- Standardise what you trust – and what you ignore – so reporting supports decisions instead of debates.
Good measurement in 2026 isn’t about precision. It’s about consistency and clarity.

Budgets: Tighter spend, higher standards
All of these changes played out under increasing financial scrutiny.
Marketing budgets tightened. “Test and learn” became harder to justify. Every channel needed a clearer role and rationale.
Yet the strongest performers didn’t simply cut activity – they reallocated with intent.
What to do about it
To manage budgets more effectively:
- Separate core performance from growth investment so cuts don’t damage long-term demand.
- Build scenario plans to stay proactive rather than reactive.
- Allocate spend based on outcomes, not historical channel splits.
Budget pressure didn’t reward caution – it rewarded clarity.

Turning change into advantage
2025 was the year digital marketing stopped behaving predictably.
Search visibility no longer guaranteed traffic. Paid performance became harder to scale. Customer journeys fragmented across more touchpoints. Measurement lost certainty just as budgets came under greater scrutiny.
For many teams, this created frustration.
For the best-performing brands, it created focus.
The marketers who pulled ahead in 2025 weren’t those chasing every new tactic or tool. They were the ones who stepped back, reassessed how discovery actually works today, and aligned their channels around clear roles – from creating demand, to capturing intent, to proving impact.
As we move into 2026, that system-level thinking is no longer optional. It’s the difference between reacting to change and using it as an advantage.
A practical next step
If any of this feels familiar:
- SEO performance looks “fine” but pipeline is down
- Paid Media feels more volatile than it should
- Reporting no longer tells a clear story
…it’s usually a sign that the discovery system needs recalibrating, not that any single channel is broken.
At Common Ground, we work with teams to pressure-test their full digital ecosystem – across SEO, content, GEO, paid media, local marketing, customer journey, and measurement – to identify where effort is being diluted and where it can drive the biggest commercial impact.
