Should I optimise for all AI search engines simultaneously?

The foundational work — GBP, reviews, structured data, quality content — benefits all of them. You don't need separate strategies for each. The differentiated work (Bing Places for ChatGPT/Copilot, specific FAQ content for Perplexity) adds incrementally on top of the foundation. Build the foundation first, then layer the platform-specific optimisations.

Are there AI search engines I should be watching that aren't on this list?

Claude (Anthropic) is expanding web access and is used by a significant professional audience. Meta AI integrated into WhatsApp and Instagram has high reach for consumer businesses. Apple's Siri and emerging on-device AI assistants are becoming business discovery channels as they improve. The landscape is moving fast — the signals that work today (reviews, structured data, quality content) are broadly applicable to emerging AI search channels.

AI Search Engines Ranked for Business Visibility

For most businesses, the AI search priority order is: Google AI Overviews first (highest volume, same signals as Google SEO), ChatGPT second (largest dedicated AI user base), Microsoft Copilot third (Bing-based, significant enterprise adoption), Perplexity fourth (smaller but high-value audience), Google Gemini fifth as an assistant (separate from AI Overviews). Optimise in that order.

Google AI Overviews: integrated directly into Google Search results, they reach the full Google audience — billions of queries per day. For any business where buyers use Google to research, AI Overviews are the most important AI channel. The optimisation work (GBP, reviews, structured data, content) is the same as traditional Google SEO plus schema implementation.

ChatGPT: over 100 million weekly active users. The user base is diverse — consumers, professionals, students — making it relevant for both B2C and B2B businesses. For local recommendation queries, ChatGPT with browsing is a significant source of business discovery. Second priority for most businesses after Google.

Microsoft Copilot: integrated into Windows, Office, Edge, and Bing. Enterprise adoption through Microsoft 365 means professional and B2B users interact with Copilot daily. For B2B businesses and professional services, Copilot's enterprise reach makes it more important than its standalone market share suggests. Bing Places optimisation is the primary lever.

Perplexity: smaller user base but high engagement from technical and research-oriented users. For professional services firms, engineering companies, and B2B technology businesses, Perplexity's audience quality may outweigh its volume. Content quality and citation signals are the primary lever.

Google Gemini as assistant: the most advanced integration with personal data (Gmail, Calendar, Drive), making it powerful for existing Google users. Business visibility through Gemini follows the same signals as Google AI Overviews.
