4、分析模型构建指标
1.流量指标分析
pv
、uv
、消费用户数占比、消费用户总访问量占比、消费用户人均访问量、跳失率。
PV UV
# 总访问量
pv = behavior[behavior['type'] == 'pv']['user_id'].count()
# 总访客数
uv = behavior['user_id'].nunique()
# 消费用户数
user_pay = behavior[behavior['type'] == 'pay']['user_id'].unique()
# 日均访问量
pv_per_day = pv / behavior['date'].nunique()
# 人均访问量
pv_per_user = pv / uv
# 消费用户访问量
pv_pay = behavior[behavior['user_id'].isin(user_pay)]['type'].value_counts().pv
# 消费用户数占比
user_pay_rate = len(user_pay) / uv
# 消费用户访问量占比
pv_pay_rate = pv_pay / pv
# 消费用户人均访问量
pv_per_buy_user = pv_pay / len(user_pay)
# SQL
SELECT count(DISTINCT user_id) UV,
(SELECT count(*) PV from behavior_sql WHERE type = 'pv') PV
FROM behavior_sql;
SELECT count(DISTINCT user_id)
FROM behavior_sql
WHERE WHERE type = 'pay';
SELECT type, COUNT(*) FROM behavior_sql
WHERE
user_id IN
(SELECT DISTINCT user_id
FROM behavior_sql
WHERE type = 'pay')
AND type = 'pv'
GROUP BY type;
print('总访问量为 %i' %pv)
print('总访客数为 %i' %uv)
print('消费用户数为 %i' %len(user_pay))
print('消费用户访问量为 %i' %pv_pay)
print('日均访问量为 %.3f' %pv_per_day)
print('人均访问量为 %.3f' %pv_per_user)
print('消费用户人均访问量为 %.3f' %pv_per_buy_user)
print('消费用户数占比为 %.3f%%' %(user_pay_rate * 100))
print('消费用户访问量占比为 %.3f%%' %(pv_pay_rate * 100))
总访问量为 6229177
总访客数为 728959
消费用户数为 395874
消费用户访问量为 3918000
日均访问量为 389323.562
人均访问量为 8.545
消费用户人均访问量为 9.897
消费用户数占比为 54.307%
消费用户访问量占比为 62.898%
跳失率
# 跳失率:只进行了一次操作就离开的用户数/总用户数
attrition_rates = sum(behavior.groupby('user_id')['type'].count() == 1) / (behavior['user_id'].nunique())
# SQL
SELECT
(SELECT COUNT(*)
FROM (SELECT user_id
FROM behavior_sql GROUP BY user_id
HAVING COUNT(type)=1) A) /
(SELECT COUNT(DISTINCT user_id) UV FROM behavior_sql) attrition_rates;
print('跳失率为 %.3f%%' %(attrition_rates * 100) )
跳失率为 22.585%
2、用户消费频次分析
# 单个用户消费总次数
total_buy_count = (behavior[behavior['type']=='pay'].groupby(['user_id'])['type'].count()
.to_frame().rename(columns={'type':'total'}))
# 消费次数前10客户
topbuyer10 = total_buy_count.sort_values(by='total',ascending=False)[:10]
# 复购率
re_buy_rate = total_buy_count[total_buy_count>=2].count()/total_buy_count.count()
# SQL
#消费次数前10客户
SELECT user_id, COUNT(type) total_buy_count
FROM behavior_sql
WHERE type = 'pay'
GROUP BY user_id
ORDER BY COUNT(type) DESC
LIMIT 10
#复购率
CREAT VIEW v_buy_count
AS SELECT user_id, COUNT(type) total_buy_count
FROM behavior_sql
WHERE type = 'pay'
GROUP BY user_id;
SELECT CONCAT(ROUND((SUM(CASE WHEN total_buy_count>=2 THEN 1 ELSE 0 END)/
SUM(CASE WHEN total_buy_count>0 THEN 1 ELSE 0 END))*100,2),'%') AS re_buy_rate
FROM v_buy_count;
topbuyer10.reset_index().style.bar(color='skyblue',subset=['total'])
# 单个用户消费总次数可视化
tbc_box = total_buy_count.reset_index()
fig, ax = plt.subplots(figsize=[16,6])
ax.set_yscale("log")
sns.countplot(x=tbc_box['total'],data=tbc_box,palette='Set1')
for p in ax.patches:
ax.annotate('{:.2f}%'.format(100*p.get_height()/len(tbc_box['total'])), (p.get_x() - 0.1, p.get_height()))
plt.title('用户消费总次数')
print('复购率为 %.3f%%' %(re_buy_rate * 100))
复购率为 13.419%
3、用户行为在时间纬度的分布

# 日消费人数
daily_buy_user = behavior[behavior['type'] == 'pay'].groupby('date')['user_id'].nunique()

6、商品销量分析
# 商品总数
behavior['sku_id'].nunique()
239007
# 商品被购前产生平均操作次数
sku_df = behavior[behavior['sku_id'].isin(behavior[behavior['type'] == 'pay']['sku_id'].unique())].groupby('sku_id')['type'].value_counts().unstack(fill_value=0)
sku_df['total'] = sku_df.sum(axis=1)
sku_df['avg_beha'] = round((sku_df['total'] / sku_df['pay']), 2)
fig, ax = plt.subplots(figsize=[8,6])
sns.scatterplot(x='avg_beha', y='pay', data=sku_df, palette='Set1')
ax.set_xscale("log")
ax.set_yscale("log")
plt.xlabel('平均操作次数')
plt.ylabel('销量')
-
左下角操作少购买少,属于冷门购买频率较低的产品。 -
左上角操作少购买多,属于快消类产品,可选择品牌少,少数品牌垄断的行业。 -
右下角操作多购买少,品牌多,但是购买频率低,应为贵重物品类。 -
右上角操作多购买多,大众品牌,可选多,被购买频次高。
# 商品销量排行
sku_num = (behavior[behavior['type'] == 'pay'].groupby('sku_id')['type'].count().to_frame()
.rename(columns={'type':'total'}).reset_index())
# 销量大于1000的商品
topsku = sku_num[sku_num['total'] > 1000].sort_values(by='total',ascending=False)
# 单个用户共购买商品种数
sku_num_per_user = (behavior[behavior['type'] == 'pay']).groupby(['user_id'])['sku_id'].nunique()
topsku.set_index('sku_id').style.bar(color='skyblue',subset=['total'])
# SQL
# sku销量排行
SELECT sku_id, COUNT(type) sku_num FROM behavior_sql
WHERE type = 'pay'
GROUP BY sku_id
HAVING sku_num > 1000
ORDER BY sku_num DESC;
7、RFM用户分层
#RFM
#由于缺少M(金额)列,仅通过R(最近一次购买时间)和F(消费频率)对用户进行价值分析
buy_group = behavior[behavior['type']=='pay'].groupby('user_id')['date']
#将2018-04-13作为每个用户最后一次购买时间来处理
final_day = datetime.date(datetime.strptime('2018-04-14', '%Y-%m-%d'))
#最近一次购物时间
recent_buy_time = buy_group.apply(lambda x:final_day-x.max())
recent_buy_time = recent_buy_time.reset_index().rename(columns={'date':'recent'})
recent_buy_time['recent'] = recent_buy_time['recent'].map(lambda x:x.days)
#近十五天内购物频率
buy_freq = buy_group.count().reset_index().rename(columns={'date':'freq'})
RFM = pd.merge(recent_buy_time,buy_freq,on='user_id')
RFM['R'] = pd.qcut(RFM.recent,2,labels=['1','0'])
#天数小标签为1天数大标签为0
RFM['F'] = pd.qcut(RFM.freq.rank(method='first'),2,labels=['0','1'])
#频率大标签为1频率小标签为0
RFM['RFM'] = RFM['R'].astype(int).map(str) + RFM['F'].astype(int).map(str)
dict_n={'01':'重要保持客户',
'11':'重要价值客户',
'10':'重要挽留客户',
'00':'一般发展客户'}
#用户标签
RFM['用户等级'] = RFM['RFM'].map(dict_n)
RFM_pie = RFM['用户等级'].value_counts().reset_index()
RFM_pie['Rate'] = RFM_pie['用户等级'] / RFM_pie['用户等级'].sum()
fig, ax = plt.subplots(figsize=[16,6])
plt.pie(RFM_pie['Rate'], labels = RFM_pie['index'], startangle = 90,autopct="%1.2f%%",
counterclock = False,colors = ['yellowgreen', 'gold', 'lightskyblue', 'lightcoral'])
plt.axis('square')
plt.title('RFM用户分层')
-
对于重要价值客户来说,要提高该部分用户的满意度,服务升级,发放特别福利,增大该部分用户留存率,在做运营推广时也要给与特别关注,避免引起用户反感。 -
对于重要保持客户,他们购物频次较高,但最近一段时间没有消费,可以推送相关其他商品,发放优惠卷、赠品和促销信息等,唤回该部分用户。 -
对于重要挽留客户,他们最近消费过,但购物频次较低,可以通过问卷有礼的方式找出其对平台的不满,提升购物体验,增大用户粘性。 -
对于一般发展客户,做到定期发送邮件或短信唤回,努力将其转化为重要保持客户或重要挽留客户。
