TurnGEO

TurnGEO is a frozen corpus of 490 multi-turn conversations between simulated users and a search-augmented generative engine. It includes every search call and the excerpt of every retrieved page as the engine read it. With it, a GEO optimizer can be evaluated by counterfactual paired replay: rewrite one retrieved page, replay the affected turns once with the original and once with the rewrite, and compare the two answers. No web crawling is needed. The evaluation harness is turngeo (huggingface.co/spaces/dynatrace-oss/TurnGEO).

This repository also holds the run reported in the paper "TurnGEO: A Multi-Turn Benchmark for Generative Engine Optimization". turngeo recomputes the paper's results from it without LLM calls.

Access

The dataset is gated: accept the conditions on this page, then authenticate with a token (hf auth login or HF_TOKEN):

turngeo fetch                       # both corpora and the paper runs, into ./data

or with the Hub tools directly:

hf download dynatrace-oss/TurnGEO --repo-type dataset --local-dir data
from datasets import load_dataset
conversations = load_dataset("dynatrace-oss/TurnGEO", "conversations", split="train")

Contents

corpus/regen-sonnet-5.5/   the corpus the paper's experiments use (default configs)
corpus/recorded/           the corpus as first recorded, plus personas.csv (the persona scaffold)
runs/paper/                the paper's evaluation run: 10 arms on 500 test pairs
runs/paper-train/          the identity run on the training split that AutoGEO's rules were mined from

Each corpus directory has a config.json (counts, construction rules, content hash) and data/{conversations,searches,documents,brands,products}/*.parquet. The two corpora differ only in conversations. searches, documents, brands and products are byte-identical.

seeds (conversation clusters) 49
conversations 490 (10 personas per seed)
user turns 2,780
search calls 1,658
retrievals (search result rows) 6,977
documents 5,270 distinct doc_ids in 5,296 rows
brands / products 2,408 / 5,498

Tables

conversations: one conversation.

column notes
conversation_id, seed_id, persona_index seed_id is the cluster key: ten personas share a seed and often their first-turn documents
num_turns number of user turns
persona_text, goal, implicit_need, likely_evolution, seed_message the scaffold (regen-sonnet-5.5 only; for recorded see personas.csv)
termination regen-sonnet-5.5 only; always recorded (the recorded turn count was kept)
messages_json the full message list (system, human, AI with tool calls, tool results) as LangChain message dicts; parse with json.loads

messages_json is kept as a string so that every tool result stays byte-identical to what the engine read. The harness rebuilds each tool result from searches and documents and checks it byte for byte before it swaps in a rewritten page.

The system messages in messages_json are the live engine's "already searched" nudges in the middle of a turn; the engine's system prompt is not stored (it is ENGINE_SYSTEM in turngeo/prompts.py). APIs that accept system text only at the start of a request, such as Anthropic's, need these moved to the front, as turngeo does.

searches: one retrieval, i.e. one result of one search call (tool_call_id × rank). It joins to conversations on conversation_id, to documents on cache_page = cache_folder (the excerpt the engine read) and on doc_id, and to products on product_ids. Further columns: query, url, title, page_type, page_brand_id, products (annotation structs).

documents: one crawled page.

column notes
doc_id normalized URL (lower-case host, no www., no fragment or tracking parameters, no trailing slash). 16 URLs were crawled twice, so use cache_folder as the row key.
cache_folder, url, title, status status is ok except for 1 failed crawl
excerpt_md the excerpt the engine read (at most 16,000 characters; six are a few characters longer)
page_type earned, brand, marketplace or social (LLM-annotated)
doc_class, thin, wall_suspect, prose_sentences, stopword_rate, target_eligible rule-based quality flags. The harness samples rewrite targets only among target_eligible pages; ineligible pages stay in the search results as competitors.

brands / products: the entity registry. products.brand_id refers to brands.brand_id; aliases lists the surface forms.

The paper run (runs/paper, runs/paper-train)

This is a turngeo work directory cut down to the ten arms of the paper:

  • identity and its replicate;
  • Statistics Addition, Fluency Optimization and Authoritative;
  • AutoGEO with the stock e-commerce and Researchy rule sets, and with the rules re-mined on the training split (autogeo@v1);
  • Hijack;
  • the attribution ceiling.

Every treatment arm includes the title channel. The run covers 500 test pairs from 40 seeds, sample a20256ff…. One sampled page that the optimizer provider's content filter rejected was replaced by a page of the same stratum (sample.json → substitutions).

path content
sample.json, run_config.json the drawn sample and the models per role
results/<arm>/scores.csv one row per arm, pair, turn, document, brand and metric, with an explicit omit_class where a metric is undefined
results/<arm>/compare.csv, summary.json paired deltas against identity with seed-clustered bootstrap CIs; the run's settings and prompt digests
arms/<arm>/*.jsonl rewrites, engine answers, extracted claims, attribution, sentiment and faithfulness labels
usage.jsonl tokens per model call
artifacts/autogeo/v1/artifact.json the rules mined on the training split

runs/paper-train holds the identity run on the training split that the rules were mined from.

Models: engine Claude Sonnet 5.5, judge GLM-5.3, optimizer GPT-6.1 Sol. The runs were made through private gateways. The model ids in these files are the public ones, and recorded_as keeps the original profile names and settings.

Caveats

  • Cluster by seed_id. The 490 conversations form 49 clusters. Confidence intervals that treat conversations as independent are too narrow.
  • Simulated users. Only the first user message of each conversation is from a real person.
  • Model annotations. page_type, brands and products are LLM annotations.
  • Excerpts only. Pages are truncated to about 16,000 characters. Full pages and raw HTML are not included.
  • Removed metadata. Request ids and HTTP headers of the recording's API responses were removed from messages_json.

Licensing

  • Our layers are released under CC BY-NC-SA 4.0. They are the conversations, search records, annotations, entity registry, scaffold and the paper run. The NC-SA terms follow from PersonaHub: persona_text reproduces PersonaHub personas (CC BY-NC-SA 4.0), and the simulated messages are conditioned on them.
  • Search Arena first messages (CC BY 4.0, Miroyan et al., 2025) are included as PII-redacted upstream and filtered to brand-related conversations.
  • Document excerpts (documents.excerpt_md, and the tool results inside messages_json) are third-party text. We do not own any of the text from which these excerpts were extracted.
