KEYWORD-ENGINE v1.0：任意 Agent 能跑的通用找词工程书，数据只用 Google 官方口径，每个门槛都从数据里算 🔭 丢给任意 Agent → 给它一个词根和目标市场 → 拿到「真在涨、搜的人够多、前十还有空位」的候选词矩阵，每个词标 优先 / 可做 / 放弃，附证据和数据日期。 思路来自 @ai_chuhai：把常见的「Trends → 第三方工具 → SERP」找词攻略升级成通用版，适用任何赛道。 ━━ 怎么用 ━━ ⚡ 最简单：右边聊天 → 选你的 Grok Bot → 把这条整帖投喂给它，说「按这本工程书做」 ① 其他 Agent（Claude Code、Codex、Cursor、Manus…）：复制下面「给 AI 看」整段到对话里，说同一句话 ② 搜索量用 Google 官方数据：Google Ads 账号里的关键词规划师，或者 Google Ads API 的历史指标接口（要开发者令牌）；有站就连上 Google Search Console。授权都走 OAuth，令牌放环境变量，别发到聊天里 ③ SERP 结构、联想词、PAA 用 DataForSEO（注册：https://try.dataforseo.com/e8hls88pdriz-drnki ）；账号密码放进环境变量 DATAFORSEO_LOGIN / DATAFORSEO_PASSWORD ④ 你只做三件事：给词根和市场，设每次花费上限，确认最后选哪些词。其余它自己做，超上限先问你 ━━ 它能做什么 ━━ ▸ 抓飙升：Google Trends 拉词根的上升查询和上升主题，用 Kleinberg 突发检测（KDD 2002）判断是不是真飙升，基线 p0 = R/D 由这个词自己 12 个月的数据算出，小基数放大的假飙升会被过滤掉 ▸ 定量级：关键词规划师给月均搜索量、近 4 年逐月搜索量、竞争指数 0–100、首页出价区间；规划师还没收录的新词不丢，在同一次 Trends 对比里拿刻度词（例如 gpts）换算成绝对量，标为「新词」 ▸ 去泛词：用 IDF（Spärck Jones 1972）给词打具体度分，泛词降权，具体长尾加分 ▸ 看竞争：前十按位置折损（NDCG，Järvelin 2002）给每个域名加权，再算 HHI 集中度（美国司法部口径，>1800 为高度集中）；域名注册时间查 RDAP 注册局官方数据，「新站还在排」的门槛取这批 SERP 自己的年龄分位数 ▸ 找缺口：用 BM25 算长尾词和前十标题、摘要的匹配度，匹配度低说明现有结果没讲清楚，就是内容机会 ▸ 站找词 ↔ 词找站：取前十里最年轻的站，读它自己的 sitemap 和页面标题提取目标词，回到关键词规划师验证，循环到新词的新颖度明显下降为止 ▸ 合并排序：突发强度、搜索量、增长、低竞争、内容缺口、商业价值、具体度共 7 个排名，用 RRF 融合（Cormack 2009，k=60），只用名次，不用人工定权重 ▸ 去重：用 MMR（Carbonell & Goldstein 1998）加信息增益分（受 Google 专利 US11354342B2 思路启发的实现）去掉同义词，最终清单每个词都带来新东西 ▸ 闭环：上站后读 GSC 实际展示和点击，回归校准「规划师搜索量 → 你能拿到的流量」系数，判错的门槛下次自动重算 ━━ 别人怎么做 → 这本怎么做 ━━ ▸ 数据｜常见做法：Semrush、Similarweb 合租镜像，量和 KD 都是第三方模型估的 → 这本：量用关键词规划师 / Google Ads API，趋势用 Google Trends，反馈用 GSC，都是 Google 官方口径；第三方只做备选，并标明是估算 ▸ 飙升｜常见做法：7 天涨几千 % 先别信，切 12 个月凭眼睛看 → 这本：Kleinberg 突发检测，基线从这个词 12 个月数据算，持续多久才算真涨，用你历史上存活下来的新词算 ▸ 量级｜常见做法：月搜 1K–1 万 → 这本：下限 = 能覆盖单站成本的流量，用「规划师量 × 你自己 GSC 回归出的系数 × 你的 CTR 曲线 × 你的 RPM」倒推 ▸ 难度｜常见做法：KD<40 → 这本：位置折损竞争分 + HHI；可抢上限取这批「前十里有新站」的 SERP 竞争分的 P75 ▸ 新站｜常见做法：注册不到一年、DR 很低 → 这本：RDAP 查注册日期，「新」= 这批前十所有域名年龄的 P10 以内，「权威」= 域名在这批 SERP 里反复出现的次数 ▸ 涨势｜常见做法：28 天、NEW、「明显在涨」→ 这本：窗口长度按这个词自己的峰值周期定，「明显在涨」= 增长率排进这批候选词的前 10% ▸ 新词｜常见做法：第三方工具查不到量就丢，等于把真正的新词丢了 → 这本：用 Trends 刻度词换算量级，单独标「新词」进入候选 ▸ 排序｜常见做法：CPC 高的排前面，几个门槛凭经验组合 → 这本：7 个排名 RRF 融合，再用 MMR 去冗余 ▸ 闭环｜常见做法：上站后不回看，门槛永远不修 → 这本：GSC 回看，校准系数和竞争门槛每轮更新 ━━ 说明 ━━ ▸ 关键词规划师和 Google Ads API 免费，但要有 Google Ads 账号；API 还要申请开发者令牌。没有投放记录的账号，规划师界面可能只给区间值，工程书会照实标出区间 ▸ DataForSEO 按次计费，Google 自然搜索标准队列约 $0.0006 / 次，联想词和 PAA 另计；新号送 $1 试用额度，最低充值 $50，以官网实时价格为准。每次跑之前它先报预估花费，绝不自动充值 ▸ 演示用的词根、刻度词只是例子，不当门槛；所有门槛每次都用这次拉回来的数据重算，并注明样本量和日期 ━━ 给 AI 看（以下勿改，整段复制给任意 Agent）━━ ::ILANG::v5.0 [TYPE:prompt][ID:KEYWORD-ENGINE][VERSION:1.0][DATE:2026-10-28][LANG:en] [FROM:@ai_chuhai][TO:@AGENT][STATUS:active] ::MODULE::ATTRIBUTION{ [METHOD] Max (@ai_chuhai, https://x.com/ai_chuhai): first-party Google data only, every cut computed from data, rank fusion plus GSC feedback loop [CONTRAST] 常见的 Trends→第三方工具→SERP 循环打法: Trends rising, third-party volume and KD filters, SERP new-site check, competitor keyword reverse lookup, fixed thresholds [ENGINEERING] @ai_chuhai, iLang IML;
