SEO in 2026: What Has Changed and What Still Works

With AI reshaping search results, what should businesses do to keep appearing?

If you work in digital marketing or simply depend on Google to attract customers, 2026 has brought changes you cannot ignore. The introduction of AI Overviews (formerly known as SGE, or Search Generative Experience) has fundamentally altered how search results work. For some queries, Google no longer even sends users to external websites: it presents the answer directly, generated by AI, at the top of the page.

This does not mean SEO is dead. It means SEO has changed. And for European businesses — many of which still do not do basic SEO — the opportunity is, paradoxically, greater than ever.

What Has Changed: The End of Generic Informational SEO

AI Overviews and the Decline of Informational Traffic

When someone searches "what is SEO" or "how does a CRM work", Google now presents an AI-generated summary that answers the question directly. The user gets the information they needed without clicking any result. Recent studies indicate that traffic to purely informational content has dropped by 20% to 40% in categories where AI Overviews are active.

The Generic 1,000-Word Article No Longer Works

For years, the formula was simple: choose a keyword, write a minimally competent 1,000-word article, publish it, and wait for Google to index and send traffic. In 2026, this type of content is being systematically replaced by AI summaries. If your article offers nothing the AI cannot synthesise, it becomes redundant.

AI Summaries Are Replacing Clicks

The "zero-click search" phenomenon already existed with featured snippets, but AI Overviews have taken it to another level. For simple informational queries, click-through rates on organic results are in consistent decline. This forces a strategic shift for anyone who depends on organic traffic.

What Still Works (and Will Continue to Work)

1. Transactional SEO: Keywords with Purchase Intent

Searches like "CRM agency in Lisbon", "website cost for restaurant" or "best invoicing software Portugal" continue to generate clicks. Why? Because the person does not just want information — they want to make a buying decision. AI can present options, but the user needs to visit the website to compare, see pricing, read testimonials and get in touch.

Investing in transactional keywords — terms that indicate intent to buy or hire — is the safest bet in SEO for 2026. These keywords may have lower search volume, but they have dramatically higher conversion rates.

2. Local SEO: Google Business Profile and Reviews

Local SEO is perhaps the channel least affected by AI Overviews. When someone searches "accountant near me" or "marketing agency Porto", Google continues to show the map with local results. And the ranking factors remain the same:

• Complete and up-to-date Google Business Profile (hours, photos, description, services)
• Genuine and recent reviews (quantity and quality of ratings)
• NAP consistency (Name, Address, Phone identical across all directories)
• Local relevance of the website (mentions of the city/region, localised content)

3. E-E-A-T: Experience, Expertise, Authoritativeness and Trustworthiness

Google increasingly values content created by people with real experience in the subject. The extra "E" (for Experience) was added precisely to differentiate content written by those who have done from content written by those who have merely researched. In practice, this means:

• Articles signed by identifiable authors with verifiable credentials
• Real cases and original examples, not generic information replicated from other websites
• Complete and credible "About Us" pages and team profiles
• Mentions and citations on other relevant industry websites

4. Quality Backlinks

Backlinks remain one of the most important ranking factors. What has changed is that quality completely outweighs quantity. A link from a relevant national news portal is worth more than 100 links from obscure directories. Strategies that work: media collaborations, guest posts in industry publications, participation in events and conferences with online coverage.

5. Technical SEO: Core Web Vitals

The technical foundation of the website remains fundamental. Google's Core Web Vitals measure user experience: loading speed (LCP), interactivity (INP) and visual stability (CLS). A website that is slow, blocks during loading or whose layout shifts as elements appear is penalised both in ranking and in user experience.

Many business websites fail Core Web Vitals, often because they use heavy WordPress themes, do not optimise images or load too many third-party scripts. Fixing these technical issues can, by itself, significantly improve positioning.

The SEO Reality in Europe: A Window of Opportunity

While the international debate focuses on the threats of AI Overviews, the reality for many European markets is different. Most SMEs still do not do basic SEO. Websites without meta descriptions, without heading structure, without image optimisation, without a configured Google Business Profile. This means that competition in search results is, in many sectors, surprisingly low.

For a company that invests in SEO competently, results can be much faster and more significant than in more mature markets like the US or UK. The window of opportunity is open, but it will close as more companies begin to invest.

5 Concrete Actions for 2026

• 1. Audit your website technically: Check Core Web Vitals on Google PageSpeed Insights. Fix speed issues, mobile-friendliness and indexation errors in Google Search Console.
• 2. Claim and optimise your Google Business Profile: Complete all fields, add recent photos, respond to all reviews and publish updates regularly.
• 3. Focus on transactional keywords: Instead of "what is digital marketing", optimise for "digital marketing agency Porto" or "social media management pricing".
• 4. Create content with real experience: Share case studies, concrete results and opinions grounded in your team's expertise. Sign articles with real names and credentials.
• 5. Build authority with genuine backlinks: Collaborate with industry publications, participate in podcasts, write for specialist media. Every credible mention reinforces your domain authority.

Conclusion: SEO Has Not Died, It Has Evolved

AI Overviews have changed the rules, but they have not eliminated the game. The SEO that worked in 2020 — based on word count and technical tricks — that is what is dying. The SEO that works in 2026 is more demanding, but also fairer: it rewards genuinely useful content, real experience and technically solid websites.

For businesses across Europe, the time is now. Competition is still relatively low, the tools are available, and the return on investment in well-executed SEO remains one of the highest in all of digital marketing.
