WebWalker: Benchmarking LLMs in Web Traversal
Open accessAbstract
Retrieval-augmented generation (RAG) demonstrates remarkable performance across tasks in open-domain question-answering. However, traditional search engines may retrieve shallow content, limiting the ability of LLMs to handle complex, multi-layered information. To address it, we introduce WebWalkerQA, a benchmark designed to assess the ability of LLMs to perform web traversal. It evaluates the capacity of LLMs to traverse a website's subpages to extract high-quality data systematically. We propose WebWalker, which is a multi-agent framework that mimics human-like web navigation through an explore-critic paradigm. Extensive experimental results show that WebWalkerQA is challenging and demonstrates the effectiveness of RAG combined with WebWalker, through the horizontal and vertical integration in real-world scenarios.

TL;DR
WebWalkerQA is a 680-query bilingual benchmark for evaluating LLMs on web traversal, where agents must click through subpages to answer single-source and multi-source questions. The authors also propose WebWalker, a multi-agent explorer-critic framework that outperforms ReAct and Reflexion but still remains below 40% overall accuracy with GPT-4o.
Key findings
- WebWalkerQA is challenging: the best WebWalker configuration, using GPT-4o, reaches 37.50 overall accuracy and 4.67 action count, and no method surpasses 40% overall accuracy.
- WebWalker outperforms Reflexion, which outperforms ReAct; closed-source models outperform open-source models, and accuracy declines as depth or number of sources increases.
- RAG systems struggle on WebWalkerQA: the best commercial system, Tongyi, reaches 40.73 overall accuracy, while close-book Gemini-1.5-Pro and o1-preview reach only 8.08 and 9.85 overall accuracy, respectively.
- Combining WebWalker with a naive RAG system improves performance across all difficulty levels, especially multi-source QA, and scaling action count K ∈ {5, 10, 15, 20, 25} leads to better performance.
Methods
- Benchmark construction: 680 QA pairs over 1373 webpages from conference, organization, education, and game domains; bilingual Chinese/English; generated with GPT-4o annotation followed by human verification; includes single-source and multi-source QAs with difficulty defined by page depth.
- WebWalker framework: a multi-agent explorer-critic system; the explorer follows a ReAct thought-action-observation paradigm over markdown page content and clickable HTML buttons, while the critic maintains memory and decides when to answer; all methods run zero-shot with a maximum of 15 actions.
- Evaluation: accuracy is judged by GPT-4 with CoT prompting, and action count is measured for successful executions; baselines are ReAct and Reflexion, with backbones including GPT-4o, Qwen-Plus, and Qwen2.5-{7,14,32,72}B-Instruct; commercial and open-source RAG systems are also compared.
Limitations
- Stated: WebWalkerQA currently has 680 high-quality QA pairs, with about 14k silver QA pairs not carefully human-verified; the work uses only HTML-DOM and not visual modalities such as screenshots; WebWalker is prompting-only without agent tuning; better integration with RAG systems is left for future work.
- Evident from the text: evaluation relies on GPT-4 as an evaluator rather than exact match; actions are constrained to “click”; the benchmark covers four domains and two languages, so it does not represent all web environments; in the RAG integration, the root URL is provided for WebWalker to execute.

Section 2.3 describes Mind2Web as an action-based web benchmark and says its real-world pages contain long, complex DOM structures that challenge modeling. Sections 4.2 and 3 describe cleaning HTML and say feeding raw pages directly to LLMs can be infeasible or costly. The paper does not establish that noisy or long inputs significantly hinder performance specifically because of limitations in long-context understanding. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-22.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-22.
Cited sources are checked by gpt-6-sol.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
