背景
SEO 分析师要从 SERP 数据里挖洞察,Pandas + Jupyter 是最自然的工具。serpbase + Pandas 5 分钟搞定端到端分析。
1. 准备
bash
pip install serpbase pandas jupyter matplotlib2. 端到端 Notebook
seo_analysis.ipynb:
python
# Cell 1: 导入 + 抓取数据
import requests
import pandas as pd
import matplotlib.pyplot as plt
from datetime import datetime, timedelta
# 1. 从 serpbase 抓多组数据
def fetch_serpbase(query, gl="us", num=10):
r = requests.post(
"https://api.serpbase.dev/google/search",
headers={"X-API-Key": "sk_xxx"},
json={"q": query, "gl": gl, "num": num},
timeout=10,
)
return r.json()
queries = ["python async", "rust async", "react hooks", "go web framework"]
data = []
for q in queries:
result = fetch_serpbase(q)
for i, item in enumerate(result.get("organic", []), 1):
data.append({
"query": q,
"rank": i,
"title": item["title"],
"link": item["link"],
"snippet": item.get("snippet", ""),
})
df = pd.DataFrame(data)
print(df.head(20))
print(f"\nTotal rows: {len(df)}")
print(f"Unique queries: {df['query'].nunique()}") query rank title ... link

python
# Cell 2: 数据清洗
df["domain"] = df["link"].str.extract(r"https?://([^/]+)")
df["title_length"] = df["title"].str.len()
df["snippet_length"] = df["snippet"].str.len()
df = df[df["rank"] <= 5] # 只看 top 5
print(df.describe()) rank title_length snippet_length
count 20.0 20.0 20.0
mean 2.7 42.5 118.3
std 1.4 15.2 45.7
python
# Cell 3: 可视化 - 每个关键词 top 5 排名
fig, axes = plt.subplots(1, len(queries), figsize=(20, 4), sharey=True)
for i, q in enumerate(queries):
query_df = df[df["query"] == q].sort_values("rank")
axes[i].barh(query_df["title"].str[:30] + "...", query_df["rank"])
axes[i].invert_xaxis()
axes[i].set_title(q)
axes[i].set_xlabel("Rank")
plt.tight_layout()
plt.savefig("serp_rankings.png", dpi=100)
plt.show()
python
# Cell 4: 排名分布分析
pivot = df.pivot_table(
index="query",
columns="rank",
values="title",
aggfunc="count",
fill_value=0,
)
print(pivot)rank 1 2 3 4 5
query
go web framework 1 1 0 1 1
python async 0 1 1 1 1
react hooks 0 0 1 2 1
rust async 1 0 1 1 1
python
# Cell 5: 平均排名对比
avg_rank = df.groupby("query")["rank"].mean().sort_values()
print(avg_rank)query

fig, ax = plt.subplots(figsize=(10, 5))
ax.barh(avg_rank.index, avg_rank.values, color="skyblue")
ax.set_xlabel("Average Rank")
ax.set_title("SERP Average Rank by Query")
ax.invert_xaxis()
plt.tight_layout()
plt.show()3. 高级分析
python
# Cell 7: 监控竞品
competitors = ["competitor1.com", "competitor2.com"]
for comp in competitors:
df[f"is_{comp}"] = df["link"].str.contains(comp, na=False)
print(df.groupby("query")[["is_competitor1.com", "is_competitor2.com"]].sum())
python
# Cell 8: 关键词难度分析
df["difficulty"] = df["rank"].apply(lambda r: "easy" if r <= 3 else "medium" if r <= 5 else "hard")
difficulty_pivot = df.pivot_table(
index="query",
columns="difficulty",
values="rank",
aggfunc="count",
fill_value=0,
)
print(difficulty_pivot)4. 时间序列分析
python
# Cell 9: 多天数据
historical_data = []
for i in range(7):
date = (datetime.now() - timedelta(days=i)).strftime("%Y-%m-%d")
for q in queries:
result = fetch_serpbase(q)
for item in result.get("organic", []):
for rank in [1, 2, 3]:
if item.get("rank") == rank or any(
x.get("link") == item.get("link") for x in result.get("organic", [])[:rank]
):
historical_data.append({
"date": date,
"query": q,
"domain": item["link"].split("/")[2] if "/" in item.get("link", "") else "",
"rank": rank,
})
df_hist = pd.DataFrame(historical_data)
print(df_hist.head(10))5. 5 个工程细节
细节 1:DataFrame 高效过滤
python
# 避免循环用 .apply,改用向量操作
df["is_my_domain"] = df["link"].str.contains("mysite.com", na=False)
# 慢
df["result"] = df.apply(lambda r: process(r), axis=1)
# 快(向量化)
df["result"] = process_vectorized(df)细节 2:大文件分块
python
for chunk in pd.read_csv("big.csv", chunksize=10000):
process(chunk)细节 3:缓存
python
import joblib
joblib.dump(df, "data.pkl") # 序列化
df = joblib.load("data.pkl") # 反序列化,启动快 100x细节 4:Matplotlib 样式
python
plt.style.use("seaborn-v0_8-darkgrid") # 美化
fig.set_size_inches(12, 6)
plt.rcParams["font.family"] = "sans-serif"细节 5:导出
python
# 导出为 Excel / CSV / HTML
df.to_excel("report.xlsx", index=False)
df.to_csv("report.csv", index=False)
df.to_html("report.html", index=False)6. 完整 Pipeline 集成
python
def serpbase_to_pandas_dashboard():
"""端到端 pipeline:serpbase → pandas → matplotlib → HTML"""
# 1. 拉取
data = []
for q in queries:
result = fetch_serpbase(q)
for i, item in enumerate(result.get("organic", [])[:5], 1):
data.append({"query": q, "rank": i, "title": item["title"]})
df = pd.DataFrame(data)
# 2. 清洗
df = df[df["rank"] <= 5]
# 3. 分析
avg_rank = df.groupby("query")["rank"].mean()
# 4. 可视化
fig, ax = plt.subplots(figsize=(10, 5))
avg_rank.plot(kind="barh", ax=ax)
ax.set_title("SERP Average Rank")
fig.savefig("chart.png", dpi=100, bbox_inches="tight")
# 5. 输出
df.to_html("report.html", index=False)
