ChatGPT Search (SearchGPT)

Also known as: ChatGPT Search, SearchGPT, GPT Search

ChatGPT Search, announced beforehand as "SearchGPT", is the web search engine OpenAI has built into ChatGPT and made publicly available in October 2024. Instead of a classic list of results it produces an answer written by the model, with sources linked visibly as citations — typically two to four per answer. It is one of the fastest-growing search engines of the AI era and one of the most important target engines for GEO, because ChatGPT users click through to cited sources at a high rate.

How ChatGPT Search differs from classic search

Getting into ChatGPT Search

Bing as the back end of ChatGPT Search

This carries an important strategic implication: ChatGPT Search uses Bing for its live retrieval. Anyone who ranks well in Google but systematically ignores Bing has poorer chances in ChatGPT Search. Bing SEO has become relevant again — submitting the sitemap to Bing Webmaster Tools, tending Bing visibility, verifying the API. A few hours of work that pays off in GEO visibility by way of the ChatGPT bridge.

Example from practice

Example: A B2B magazine tracked its visibility in ChatGPT Search across 16 core topics from October 2024 onwards, starting at a citation rate of 12 per cent. It submitted its sitemap to Bing, verified access for OAI-SearchBot, gave every pillar page a clear question-and-answer structure and added visible update dates. Five months later the citation rate stood at 47 per cent, with 2,300 monthly clicks of direct referral traffic from chatgpt.com — a traffic source that had not existed twelve months earlier.

Frequently asked questions

What is ChatGPT Search (SearchGPT)?
ChatGPT Search is the live web search function inside ChatGPT, generally available since 2024 after a short beta under the name "SearchGPT". It combines model-written answers with current web results and source citations, and competes directly with Google and Perplexity.
How does ChatGPT Search differ from Google?
It is answer-oriented rather than link-oriented. Google shows a list of results; ChatGPT Search generates a structured answer citing three to eight sources. The answers are longer and richer in context, but less quick to scan.
How do you get into ChatGPT Search?
Allow OAI-SearchBot and ChatGPT-User in robots.txt, use a clear answer structure with an answer-first opening, FAQs and lists, keep publication dates current and build domain authority. The Rankmio citation tracker measures ChatGPT Search citations per query.
Does ChatGPT Search replace Google?
For certain types of query, yes. Research-heavy, longer questions are migrating to ChatGPT and Perplexity. Purchase queries, local searches and navigation stay with Google. The sensible strategy is to be visible in both channels.
