竞品 SERP 分析

批量抓取行业核心词的 Google 搜索结果，分析竞品出现频次、Featured Snippet 占比、排名分布，输出竞品 SEO 能力对比报告。

涉及 API

API	用途
Google Organic Live Advanced	完整 SERP（含精选摘要、PAA、广告）
Google Organic Live Regular	仅需 Top 10 有机结果时

工作流

1. 定义行业核心词列表（20–50 个）
2. 定义竞品域名列表
3. 批量 SERP 抓取
4. 统计每个竞品：出现次数、平均排名、Featured Snippet 次数
5. 生成对比报告

API_KEY = "smt_live_YOUR_KEY"
BASE = "https://api.seermartech.cn/v3"
HEADERS = {"Authorization": f"Bearer {API_KEY}"}

CORE_KEYWORDS = [
 "SEO工具", "关键词研究工具", "外链分析工具",
 "网站排名查询", "竞品分析工具",
 # ... 20–50 个行业词
]

 timeout=60,
 )
 resp.raise_for_status
 return resp.json["tasks"][0]["result"][0]["items"]

def analyze_competitors:

 # 输出报告

TypeScript

 },

 location_code: 2156,
 language_code: "zh",

报告指标说明

指标	含义	业务价值
Appearances	在多少核心词 SERP 中出现	可见度广度
Avg Rank	出现时的平均排名	可见度深度
FS (Featured Snippet)	获得精选摘要次数	内容权威度信号
Top 3 Rate	排名前 3 的比例	高价值流量占比

成本估算

规模	模式	参考费用
30 核心词 × Advanced	Live	≈ ¥0.96
50 核心词 × Advanced	Live	≈ ¥1.60
50 核心词 × Regular（仅 Top 10）	Live	≈ ¥1.60

建议每月跑一次完整分析，新竞品加入或行业词库更新时再跑。

最佳实践

1. 词库选择：从 关键词研究工作流 输出的高搜索量词中选取 Top 30–50
2. depth 控制：分析 Top 20 足够，设 depth: 20 节省 cost
3. SERP 特征：Advanced 版可统计 PAA、广告位，Regular 仅有机
4. 多地区：出海业务需按 location_code 分地区跑，见 位置代码参考
5. 结合外链：SERP 可见度 + 外链对比 = 完整竞品画像
