Introduction
By early 2026, about 60% of Google searches end without a click to a website. Google's AI Overviews appear in 27-30% of search queries, which is 700% more than in early 2025. For businesses, this means a need to adapt: classic SEO methods work but require supplementation with strategies for AI visibility. [1]
In this series of articles, you will learn how SEO works in 2026, considering changes in Google algorithms and the emergence of AI search. You will get practical instructions on optimizing a website for AI models, learn about new performance metrics, and find out how to adapt content for citation in AI Overviews.
First, let's define the terminology and provide a definition of SEO that can be formed considering the emerging trends of 2026 in the Runet.
SEO (Search Engine Optimization) – is a set of measures to optimize a website to improve its visibility in search engines (Google, Yandex) and AI platforms (ChatGPT, Perplexity, Claude), including technical optimization, creating high-quality content, and building brand authority to attract targeted organic traffic.
How has SEO changed with the advent of AI models in 2026?
SEO in 2026 – is not just optimization for search engines, but a comprehensive brand visibility strategy in the AI search ecosystem, where priority is given to expertise, content structure, and the ability to be cited by artificial intelligence.
Studies show that websites cited in AI Overviews receive a 35% higher organic CTR and a 91% higher paid CTR compared to non-cited sources. At the same time, the overall organic CTR decreased by 34.5% for queries with AI Overviews, which requires a review of approaches to measuring SEO performance.[2][4]
From keywords to understanding entities (Entity SEO)
Search algorithms in 2026 have moved from simple keyword matching to understanding entities. Google and AI systems now analyze:
Who you are: identification of the brand, company, expert;
What you offer: products, services, expertise;
Why you can be trusted: E-E-A-T signals, reputation, authority;
Context and intent: what exactly the user is looking for, not just what words they use.
According to Search Engine Journal, inconsistency in brand description across different platforms can reduce visibility in AI results by 40%. [5]
Generative Engine Optimization (GEO) – a new discipline
Traditional SEO focused on getting into the top 10 organic results. GEO (generative engine optimization) solves the problem of getting inside AI answers, where your content is cited as an authoritative source.
Key platforms for GEO in 2026:
Google AI Overviews (appear in 27-30% of queries); [2]
ChatGPT with integrated search;
Perplexity AI (positioned as an "answer engine");
Claude with research features;
YouTube (the second largest search engine).
Zero-click search as a new reality
According to Semrush data for 2025, 58.5% of search queries in the US and 59.7% in Europe end without a single click to an external website. Featured snippets, People Also Ask, local results, and especially AI Overviews provide answers directly in the search results.[1]
Important detail: for queries with AI Overviews, the zero-click rate reaches 83%, which means that users get a complete answer without having to leave Google.[6]
Adaptation strategy:
Focus on branding through zero-click visibility;
Attracting users at the late stages of the funnel (when they are ready to buy);
Optimization for citation as an authoritative source;
Measuring not only clicks but also impressions and brand mentions.
Important! Brands whose content is cited in AI answers gain a significant advantage: users who do click through to the website show a higher readiness to convert.
