# Visdenda > Google Search update radar + site audits. Official-channel listening > becomes versioned rules, then page-by-page audits with evidence replay. ## Pages - [Home](https://visdenda.com/): one free lightweight audit, no login. - [Pricing](https://visdenda.com/pricing): free diagnosis tier; Pro priced per verified site, billed through Paddle. Amounts confirmed on checkout. - [Public radar](https://visdenda.com/radar): P0/P1 update summaries with affected rules and official sources. P2 volatility never enters. - [AI crawler directory](https://visdenda.com/crawlers): 63 answer, search, training and ads crawlers with robots.txt tokens, documented user agents, reverse-DNS suffixes and vendor sources. Per-crawler pages: https://visdenda.com/crawlers/{slug} (for example https://visdenda.com/crawlers/google-google-agent). Machine-readable: https://visdenda.com/crawlers.json. - [Crawler probe SDK](https://visdenda.com/docs/npm): install @visdenda/agent-watch and wrap a fetch handler, a Node server or Next.js. Page scripts never see AI crawlers because bots do not run JavaScript. - [API docs](https://visdenda.com/docs): the full machine flow — create a site, verify ownership, run audits, read findings. Start here if you are an agent. - [MCP server](https://visdenda.com/mcp): what agents can ask, how to connect, and 43 tools (read-only by default) over one stateless endpoint (https://visdenda.com/v1/mcp) — project status, audit history, URL audit, radar, diagnosis and findings. Free to call, rate-limited. Setup and schemas: https://visdenda.com/docs/mcp. - [Checker library](https://visdenda.com/checkers): public explainers for the checks we run — what each verifies and what a failure looks like. One-line reference: https://visdenda.com/docs/checkers. - [Agent skill](https://visdenda.com/skills/visdenda/SKILL.md): deterministic insights → drill → fix → verify, with task playbooks under https://visdenda.com/skills/visdenda/references/ (auth, scopes, evidence contract; endpoints live in https://visdenda.com/docs/api). Index: https://visdenda.com/skills.json. ## Rules of the house - AI drafts rules; humans approve. Audits recognize `active` and nothing else. - API keys are Bearer tokens with scopes; plaintext shown once at issuance. - Quotas are counts only, never bodies; 5xx responses never count as usage. ## Product docs - **产品功能文档总览** (`README.md`): SSOT:本目录是“产品有什么功能、什么状态、怎么用”的唯一入口。 - **身份与权限(M15 机制分册)** (`access.md`): 本文放机制细节:七身份矩阵、前戏 gated 清单、配额数值。 - **AEO 能力规范(Answer Engine Optimization Spec)——Cloudflare 文档学习** (`aeo.md`): 知识源:Cloudflare 官方文档(AI Crawl Control,已核实 2026-09)+ 雷达前沿追踪;2026-10 扩容 A9–A13(依据 Google 官方口径与雷达源核实,出处见各行) 红线:AEO 没有官方排名系统(区别于 Google SEO 的公开文档体系)。 - **站点 AI 标准支持规范(AI Standards for Our Own Sites)** (`ai-standards.md`): 适用:seo-watch 与 improve-i18n 两个产品的官网与文档站 立场:我们向用户审计 llms.txt / AI 可读性(aeo.md A1–A6),自己的站点必须先达标——狗粮闭环,也是产品演示。 - **AI 接入面(P0 已落地)** (`ai-surface.md`): 外部 AI 只读调用:Bearer API Key + scope 鉴权,与内部 X-Backend-Secret 链路隔离。 - **审计(站点核验)** (`audit.md`): 按站点跑审计:沿 auditUrls 逐页抓取,对全部 active 规则跑检查器,结论逐条入库,可回放可复验。 - **控制台** (`console.md`): SaaS 后台:总览/雷达/任务/通知/自检/档位/账单。 - **设计自查(Red Team Review)** (`design-review.md`): 对象:SaaS 化路线(saas-optimizer-roadmap)+ 本轮新增的 metrics/aeo 规范 结论:3 个设计错误已修正、4 个承诺降级、4 个结构性风险带杀掉标准。 - **术语表** (`glossary.md`): triage:雷达定级:p0(转规则试点)/ p1(观察)/ p2(只监控)/ noise(结构化噪音)/ undecided(人工看)。 - **第三方数据源集成策略** (`integrations.md`): 个人后台(admin console)是否接入 GA4、Cloudflare Web Analytics beacon、Ahrefs / Adobe("AE" 待 Q19 确认指代)等三方数据的准入清单与分级。 - **任务与覆盖率** (`jobs.md`): ingest/backfill 走队列异步跑,取消只打标记、失败进重试/DLQ。 - **关键词监控与竞品对比规范(Keywords Spec)** (`keywords.md`): 数据源纪律为本规范核心 原则:先定数据源,再定功能。 - **指标体系规范(Metrics Spec)——谷歌官方文档学习** (`metrics.md`): 知识源:Google 官方文档(出处逐项标注,链接随 rules 版本化) 原则:每项指标必须有官方出处、确定性判定、明确采集方式与已知局限。 - **产品真相清单(营销口径 SSOT)** (`offer-truth.md`): 本次四面重写(pricing / 对照表 / alternatives / docs/api)的唯一口径来源。 - **P1 任务拆解(Backlog)** (`p1-backlog.md`): 验收对齐 saas-optimizer-roadmap §11 P1 + metrics/aeo 规范 | 每任务:改动 → 验收。 - **产品需求总纲(PRD)** (`prd.md`): 本文件是功能需求条目的唯一来源:每条需求一个稳定 FR 编号、一句话行为描述。 - **雷达(更新监听)** (`radar.md`): 从 Google 官方渠道拉取更新,去重入库,按定级进入规则链。 - **规则(核验依据)** (`rules.md`): Google 官方文档提炼成版本化规则。 - **SaaS 演进路线(草案未实施)** (`saas-roadmap.md`): 本页只收敛“要做什么、不做什么、分几期”。 Full detail: [llms-full.txt](https://visdenda.com/llms-full.txt)
