The State of Search in 2026
Search behaviour has fractured. For the first time in two decades, a competitor has reached double-digit search market share against Google. ChatGPT processes what's now estimated to be 17% of global search queries (First Page Sage, 2026). Google itself is serving AI-generated answers (AI Overviews) to over 1.5 billion users monthly. Perplexity is growing as a research and discovery tool with its citation-first model.
The practical consequence for UK businesses: if you only optimise for Google's traditional 10 blue links, you're invisible in a growing portion of searches — particularly the high-value recommendation and comparison queries where users are actively looking for solutions like yours.
Citation capsule: Only 23% of marketers currently invest in GEO measurement and prompt tracking. 78% of companies fund GEO programmes — nearly identical to the 77.5% funding traditional SEO and PPC. 63% plan to increase GEO investment in the next 12 months.

What SEO Does That GEO Doesn't
Traditional SEO remains essential for commercial intent searches — people looking to buy, contact, or visit. "Plumber Bristol", "accountant near me", "buy running shoes UK" — these queries are still primarily handled by Google's traditional results, local pack, and Google Shopping.
SEO also drives the majority of inbound traffic to most UK small business websites today. Backlinks from credible sites, strong domain authority, and well-ranked pages for commercial keywords are still the primary traffic drivers for most SMEs.
Abandoning SEO for GEO would be a mistake — traditional organic traffic is not going away, it's just being supplemented.
What GEO Does That SEO Doesn't
GEO targets the growing category of AI-mediated discovery. When someone asks ChatGPT "who are the best UK SEO consultants?" or asks Google "what should I look for in a small business accountant?", the answer comes from AI systems — not the traditional 10 blue links.
These discovery queries are particularly high-value because the user is actively asking for a recommendation. Being the business that AI systems recommend in those moments is a significant commercial opportunity — particularly as AI-referred traffic converts at 4.4x the rate of traditional organic search.
Specific things GEO addresses that SEO doesn't:
- Whether GPTBot, ClaudeBot, and PerplexityBot can access your site
- Whether your content is structured for AI extraction (answer-first format)
- Whether your business has clear entity signals across the web
- Whether your schema markup helps AI systems understand your content
- Whether you have an llms.txt file guiding AI systems
The Overlap: What SEO and GEO Share
The good news: most SEO investments also support GEO. Fast-loading pages are easier for both Google's crawler and AI bots to process. Quality, expert content ranks better in Google and gets cited by AI systems. Schema markup helps both traditional rich results and AI structured understanding. Strong E-E-A-T signals benefit both dimensions.
The most efficient approach is a combined audit that identifies the highest-impact improvements across both SEO and GEO dimensions — prioritising fixes that benefit both channels simultaneously.
Do UK Small Businesses Need Both in 2026?
Yes — but the balance depends on your business type:
- Local service businesses (plumbers, electricians, restaurants): SEO and local search still dominate. GEO is important but secondary. Start with SEO, layer GEO.
- Professional services (accountants, consultants, solicitors): AI recommendation queries are common in this category. SEO and GEO are roughly equal priority.
- E-commerce: Traditional Google Shopping and organic rankings are primary. GEO is emerging for product discovery via ChatGPT. SEO-first with GEO layered in.
- SaaS and digital products: AI discovery is significant — ChatGPT is now a primary discovery channel for software. GEO and SEO are co-equal priorities.
Frequently Asked Questions
Can a small UK business implement GEO without a technical team?
Many GEO improvements don't require technical expertise: checking robots.txt for AI bot blocking (then asking a developer to fix it), structuring blog content in answer-first format, adding FAQ sections to key pages. Technical elements like schema markup and llms.txt require developer involvement, but the content-level GEO improvements are accessible to non-technical teams.
How quickly do GEO improvements show results?
Faster than traditional link-building SEO. Technical changes (allowing AI bots, adding schema) can take effect within weeks as AI systems re-crawl. Content restructuring for answer-first format takes longer as it requires updating existing pages and waiting for AI systems to incorporate the updated content. Expect to see meaningful changes in 1–3 months for technical fixes, 3–6 months for content-level improvements.
Is GEO a replacement for content marketing?
No — GEO is an additional dimension that makes your existing content marketing more effective for AI discovery. Rather than creating separate GEO content, the goal is to ensure your existing content is structured and accessible for AI systems. This often means reformatting existing content with answer-first structure, adding FAQ sections, and ensuring schema markup is present.
