What is ChatGPT Search and how is it different from regular ChatGPT?

ChatGPT Search is OpenAI's integration of real-time search into ChatGPT. Instead of relying on its training data (with the susceptibility to hallucination that entails), ChatGPT Search can actively search the web and deliver sourced answers with links to the original sources.

It rolled out globally in late 2024 and is available in 2026 for all ChatGPT Plus and Enterprise users, as well as in the free version with some limitation.

Why is ChatGPT Search relevant to your business visibility?

When a potential customer asks ChatGPT Search "Which are the best web agencies in Sweden?" or "How much does it cost to build an app?" the system actively searches for relevant pages and cites them in the response. It's basically the same mechanism as Perplexity and Google AI Mode - a new competitive arena for organic visibility that didn't exist two years ago.

Optimization for ChatGPT Search follows the same logic as GEO: authoritative content, clear answers to specific questions, and consistent presence on external platforms that ChatGPT indexes.

What does ChatGPT Search index?

ChatGPT Search does not index the entire web like Google. It uses Bing as the primary index source, supplemented by other data sources. This means that Bing presence – historically ignored by most SEO strategists – takes on new relevance. Make sure your website is indexed in Bing Webmaster Tools.

Make sure your website is indexed in Bing Webmaster Tools (free and takes 15 minutes). Publish regular content that answers specific questions your target audience asks. Build external references: omnipotent in newspaper articles, industry lists and partner site substitutions signal authority to ChatGPT Search as well. Make sure your robots.txt doesn't block ChatGPT's own crawler: GPTBot.
