• AI tools like ChatGPT drive new citation-focused SEO
• Yandex and Baidu remain essential for Russian, Chinese markets
• Amazon and TikTok require distinct product and short‑form strategies

Pulse Analysis

Google’s near‑90 % dominance still defines the baseline for any search strategy, yet the rise of AI Overviews is eroding click‑through rates. Zero‑click results now surface answers before users reach a site, forcing marketers to optimize for featured snippets, People Also Ask blocks, and structured data that can be lifted into AI summaries. While the traffic volume remains unmatched, the cost of securing top positions is climbing, prompting a shift toward authority signals and rich‑media assets that satisfy both human users and AI parsers.

Bing’s modest but steady gain reflects Microsoft’s aggressive integration of generative AI through Copilot and its partnership with OpenAI’s ChatGPT. Because ChatGPT pulls web results from Bing’s index, content that ranks well on Bing enjoys a secondary exposure path in AI‑driven answers. This creates a cost‑effective niche for advertisers: fewer competitors vie for the same slots, and Microsoft Ads can import Google campaigns with minimal friction. Optimizing for Bing also means paying attention to desktop‑centric signals, keyword specificity, and emerging social‑signal weightings that differ from Google’s algorithm.

The rapid growth of AI search platforms signals the birth of Generative Engine Optimization (GEO). Brands must monitor citation visibility, produce clear, well‑structured content, and embed schema markup to increase the likelihood of being referenced in AI answers. Simultaneously, vertical platforms like Amazon’s A10 algorithm and TikTok’s engagement‑first recommendation engine demand dedicated keyword research and creative formats. Ignoring these channels risks ceding market share to competitors who diversify their search presence across traditional, AI, and platform‑specific ecosystems.
