SEO trends in 2026 are moving faster than most Swiss SMEs can keep up with. Google’s AI Overviews have fundamentally changed what appears above the fold, voice search is mainstream, and long-tail strategies are more valuable than ever. What worked in 2023 is often not enough today. Whether you run a webshop in Zurich or a B2B company in Zug, the rules have shifted. Here is what actually matters right now, based on what we see in practice every day at ONELINE.
What are the most important SEO trends at the moment?
At the moment, the following points are considered the most important trends in the field of search engine optimisation:
• AI Overviews and GEO (Generative Engine Optimisation)
• Rich Snippets
• Video content
• Voice Search
• Page Experience and Core Web Vitals
• Long-tail SEO
AI Overviews and Generative Engine Optimisation
Google’s AI Overviews now appear for a significant share of searches, especially on informational queries. In Switzerland, we are seeing this rollout accelerate through 2026 across German and French language results. The implication is significant: even a top-3 ranking may receive fewer clicks if an AI-generated summary answers the question directly at the top of the page.
What does this mean practically? Content needs to be structured so that AI systems can cite it as a source. Clear answers, structured data, authoritative signals. This is what some are calling GEO, Generative Engine Optimisation. Our experience shows that content which already performs well for featured snippets tends to be picked up by AI Overviews too. The fundamentals still apply, but the bar is higher. If you want help navigating this, our SEO team works with Swiss companies on exactly this.
Rich Snippets: Text structure is the be-all and end-all
Rich snippets are the short sections of text and other information that Google already lists directly on the search results page (SERPs).
In order to ensure that the Google algorithm displays your own website on a certain topic with a rich snippet, text structure is the be-all and end-all: questions are answered or information is conveyed with text modules that fit the topic precisely.
In addition to a short, crisp text structure, the choice of a suitable headline is also crucial.
Video content
Videos are more effective and important as online content than ever before. YouTube remains the second largest search engine globally, and short-form video now also influences how Google ranks pages. As a website operator, this trend is relevant for several reasons:
• Topics that need to be explained can be presented very well in videos.
• Professional image advertising is really well received as a video.
• Video content is an excellent way to distribute through your own social media channels.
• More videos mean better ranking signals for Google’s multimodal algorithm.
Voice Search
Searches by voice control are becoming increasingly important. This is mainly due to the increasing use of mobile devices: many users already ask the Google Assistant in their smartphone or the smart home speaker at home their questions by voice input.
Accordingly, it is becoming increasingly important to make one’s own SEO strategy fit for such voice search queries. Natural language, question-based content structures and fast-loading pages are the core levers here.
Page Experience and Core Web Vitals
Google evaluates not just content but also user-friendliness. The algorithm assesses three key aspects: loading time, interactivity and layout stability. These are the Core Web Vitals, and in 2026, Google’s Interaction to Next Paint (INP) metric has fully replaced FID as the interactivity signal. Website operators who haven’t audited their technical performance recently may be losing rankings they don’t realise they’ve lost.
The interaction of these aspects results in the overall page experience. Slow Swiss hosting setups, oversized images, or clunky mobile navigation are the usual culprits we fix when working on web development projects.
Long-tail SEO
Long-tail SEO means focusing on longer keyword phrases instead of individual words. This is more complex than optimising for single keywords, but it lets website operators occupy niches that are not very competitive while still being actively searched.
In view of AI Overviews answering simple questions instantly, long-tail SEO is increasingly a strategy for capturing users with complex, specific needs. Two sentences in an AI summary cannot replace a detailed guide. That’s where long-tail content still wins.
Orientation to Google’s AI and MUM update
By far the most important factor for search engine optimisation remains the Google algorithm. The MUM model (Multitask Unified Model) was a major step toward multimodal content understanding, evaluating text, video and audio together. In 2026, this has evolved further with Google’s Gemini integration into search.
What this means practically: content quality and topical authority matter more than keyword stuffing ever did. Google increasingly understands context, intent and the relationships between pieces of content across an entire domain.
The basics must be right: the most important SEO factors at a glance
Apart from all current SEO trends, the fundamental SEO factors still need to be solid. Anyone producing great videos but lacking a clear SEO strategy or proper user experience will still struggle in 2026. The most important ongoing SEO factors are:
• SEO strategy
• Keyword strategy
• Unique Content
• Backlinks and internal linking
• Mobile First
• Google E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness)
Note the upgrade: Google’s original E-A-T framework now includes an additional E for Experience, recognising that first-hand, real-world knowledge is a ranking signal in its own right.
Unique Content: the sacred cow of SEO
Unique content as a core SEO requirement is familiar to everyone. But with AI-generated content flooding the web, standing out has become genuinely harder. Here are approaches that still work.
Tip 1: Produce your own statistics
Studies and surveys generate proprietary data. As the producer, you own that information. Even when others pick it up, they must cite the source. In Switzerland, niche industry surveys can be particularly powerful since English-language data rarely reflects local market conditions accurately.
Tip 2: Give experts a voice
Expert opinions are trusted by readers and rewarded by Google’s E-E-A-T signals. Interviews with specialists in a field generate content that cannot simply be replicated. This approach also supports backlink acquisition naturally.
Tip 3: Create your own videos and podcasts
Text can be scraped and rephrased easily. Audio and video content is far harder to copy. Producing original multimedia content is an increasingly important differentiator, and it feeds directly into Google’s multimodal evaluation signals.
Experts refer to this kind of differentiation as a content moat: unique content that protects your site’s SEO value by being genuinely difficult to replicate.

Frequently Asked Questions
What are the most important SEO trends in 2026?
The biggest shifts in 2026 are around AI Overviews and Generative Engine Optimisation (GEO), meaning content needs to be structured so it gets cited by AI-generated summaries. Beyond that, Core Web Vitals (especially the new INP metric), long-tail content, and E-E-A-T signals remain central to strong rankings.
How do AI Overviews affect my website’s traffic?
If Google answers a query directly with an AI Overview, fewer users click through to individual websites. This particularly affects informational queries. The solution is to aim for citation within the AI Overview itself, which requires clear structure, authoritative content and strong E-E-A-T signals. Our experience in Zurich and Zug shows that well-structured content with schema markup tends to perform better here.
Is long-tail SEO still worth the effort in 2026?
Absolutely. Simple queries are increasingly captured by AI Overviews. Complex, specific searches still lead users to detailed content. Long-tail SEO is precisely where Swiss SMEs can compete effectively against larger players with bigger budgets.
What is E-E-A-T and why does it matter for SEO?
E-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness. Google uses these signals to evaluate whether content is produced by people with real knowledge and credibility. For Swiss companies, this means showcasing your team’s expertise, earning quality backlinks and keeping your content accurate and up to date.
