Introduction
By the beginning of 2026, about 60% of Google searches are completed without clicking on the site. Google’s AI Overviews appear in 27-30% of search queries, a 700% increase from early 2025. For businesses, this means adapting: classic SEO techniques work, but require complementing with AI visibility strategies. [1]
In this series of articles, you will learn how SEO works in 2026, taking into account changes in Google algorithms and the emergence of AI search. You will receive practical instructions on optimizing your site for neural networks, learn about new performance metrics, and learn how to adapt content for citation in AI Overviews.
To begin with, let’s define the terminology and give a definition of SEO, which can be formed taking into account the emerging trends of 2026 with the Runet.
SEO (Search Engine Optimization) is a set of measures to optimize a site to improve its visibility in search engines (Google, Yandex) and AI platforms (ChatGPT, Perplexity, Claude), including technical optimization, creation of quality content and building brand authority to attract targeted organic traffic.
How has SEO changed since the arrival of neural networks in 2026?
SEO in 2026 isn’t just about optimizing for search engines, it’s about a comprehensive brand visibility strategy in the AI search ecosystem, where expertise, structured content, and the ability to be cited by artificial intelligence prioritize.
Studies show that sites cited in AI Overviews receive 35% higher organic CTR and 91% higher paid CTR compared to uncited sources. Overall organic CTR declined 34.5 percent for AI Overviews queries, requiring a rethink of how SEO performance is measured. [2][4]
From Keywords to Understanding Entities (Entity SEO)
The search algorithms of 2026 moved from simple keyword mapping to understanding entities. Google and AI systems are now analyzing:
Who you are: Brand, company, expert identification
What you offer: products, services, expertise;
Why you can be trusted: E-E-A-T signals, reputation, authority
Context and intent: What the user is looking for, not just what words they use.
According to the Search Engine Journal, inconsistencies in brand description across platforms can reduce visibility in AI results by 40%. [5]
Generative Engine Optimization (GEO) is a new discipline.
Traditional SEO has focused on getting into the top 10 organic results. GEO (Generative Engine Optimization) solves the problem of getting inside AI responses where your content is cited as an authoritative source.
Key platforms for GEO in 2026:
Google AI Overviews (appears in 27-30% of queries);[2]
ChatGPT with integrated search.
Perplexity AI (positioned as an answer engine)
Claude with research functions;
YouTube (the second largest search engine).
Zero-click search as a new reality
According to Semrush data for 2025, 58.5% of searches in the U.S. and 59.7% in Europe are completed without a single click on an external site. Featured snippets, People Also Ask, local results and especially AI Overviews give answers right in the search results. [1]
For queries with AI Overviews, the zero-click rate reaches 83%, which means users get a full response without having to leave Google. [6]
Adaptation strategy:
Focus on branding through zero-click visibility
Attracting users in the late stages of the funnel (when ready to buy);
Optimization for citation as an authoritative source
Measuring not only clicks but also brand impressions and mentions.
Important! Brands whose content is cited in AI responses gain a significant advantage: users who do click through to the site show a higher willingness to convert.
To be continued.
