市场情报采集：用四类公开信号回答一个具体决策
$0.0045/页起 · 复用 4 类真实样本，按查询、地区、SKU 与时间分层
§01
这个问题是谁的，为什么值得自己搭
市场调研最容易犯的错，是先抓一大堆数据，再问“这些能说明什么”。搜索结果、地图商家、商品页和社媒内容都只是不同观测面：它们能帮助发现需求语言、供给密度、价格带和内容主题，但不能单独证明市场规模、份额或购买意愿。
这页先从一个可决策的问题出发，例如“某城市的精品咖啡供给是否集中、主流价格带怎样、用户公开讨论什么”。然后让四个已经在本站自有 Apify 账户跑过的任务各回答一小部分，并保留查询条件、来源 URL、地区和采集时间。
信息增量不在于把四张表拼成一个大表，而在于给每类信号规定能说什么、不能说什么，再用分层样本交叉验证。

一条流水线，4 个实测过的 Actor
| 工具（点进去看实测） | 在这条流水线里干什么 | 单价 |
|---|---|---|
apify/google-search-scraper | 需求语言与可见入口：固定国家、语言和查询，记录自然结果、广告与相关查询；它反映搜索呈现，不等于真实搜索量或排名原因。 | $0.0045 · 每抓 1 个搜索结果页（≈10 条自然结果）$5≈1,111 条 |
compass/crawler-google-places | 地域供给样本：按“品类 + 城市”提取商家、地址、分类、电话和网站，用于观察公开可见的供给密度。 | $0.004 · 每抓 1 家商家$5≈1,250 条 |
junglee/Amazon-crawler | 商品与价格带：对明确 SKU 或类目样本保留价格、库存、卖家与采集时间；页面状态不等于真实成交。 | $0.005 · 每抓 1 个商品$5≈1,000 条 |
apify/instagram-scraper | 公开内容主题：收集公开帖子文本、时间和互动字段，分析内容话题；互动数不能直接当购买意愿。 | $0.0027 · 每抓 1 条结果（帖子/Reel）$5≈1,851 条 |
每个工具的输出样本、真实扣费凭证与 Run ID 都在对应任务页里可查——本页只把它们组成一条流程，不重复报价、不另造数据。

先算主力搜索样本的成本
先用少量查询建立研究框架，再分别估算地图、商品与社媒样本；不要用一个单价假装整套研究只有一种成本。 单价读自主力 Actor apify/google-search-scraper 的实测价目。
抓 1,000 条 预计
$4.50≈ ¥32.40
✓ $5 免费额度足够覆盖，$0 成本开跑
容易忽略的成本
- 每次运行最低结算 $0.50——查 1 个词和查 50 个词起步价一样，**务必把一批关键词攒进同一次运行**。
- Actor 启动费 $0.001/次已包含在账单里；计算器不把一次性启动费按查询页数重复计算。
- AI 搜索引擎附加项（ChatGPT/Gemini/Perplexity）$0.2/条，是主价的 44 倍；做 GEO（生成式引擎优化）监测时按需开。
汇率 1 USD ≈ 7.2 CNY（2026-07-09）；单价为 Free 档零售价，付费套餐有阶梯折扣。
§05
从问题到周期快照：市场情报六步法
按下面顺序做一轮小型市场情报，而不是无限扩数据量：
- 写一个决策句：例如“是否要为上海精品咖啡店做一套 B2B 供应服务”。如果数据不会改变这个决策，就不采。
- 定义四层样本：10–20 个查询、2–5 个区域、20–50 个商品/商家、一个明确时间窗口。样本边界比“大数据”口号更重要。
- 分表采集：搜索、地图、商品和社媒字段不同，各自保留来源、输入、Run ID 与日期；不要先塞进一张宽表。
- 先做能被反驳的观察：例如“抽样区域内商家主要集中在两类商圈”，并注明样本。不要写“市场份额 37%”这类数据无法支持的结论。
- 用第二类信号复核：地图供给密集但搜索结果稀少，可能是查询词不对，也可能是线上可见度低；需要回到原始结果判断。
- 只为会重复的决策定时：价格和供给变化需要周期快照；一次性选题研究不必每日跑。
主力成本计算器只反映 Google 搜索 Actor 当前主计费项。整套研究的总费用取决于每个任务的样本量，应分别在对应任务页估算，不能把一个单价乘到四类数据上。
§06
上手前最后几个问题
这套数据能算市场规模或市场份额吗？
不能直接算。公开搜索、地图、商品与社媒是可见信号样本，缺少完整交易、渠道和未上线供给。它们适合发现假设、形成抽样框和跟踪变化，不足以独立证明市场份额。
市场情报和竞品情报有什么区别？
市场情报从品类、地区和需求问题出发；竞品情报从一组已知竞争者的搜索、广告与商品动作出发。两者可共享数据，但采样框和结论不同。
为什么不把所有信号做成一个总分？
四类信号的覆盖面、时间和含义不同。没有经过验证的权重会把主观判断伪装成精确数字；保留分项观察更容易回到证据。
