Unlocking Customer Loyalty Through Python and Plotly Dash
Written on
Chapter 1: Introduction to Customer Loyalty
In this article, we will explore how to gather and analyze customer data, effectively segment your audience, and develop tailored loyalty programs that truly resonate with your customers using Python. Our focus will be on implementing a customer loyalty program based on the RFM (Recency, Frequency, Monetary) methodology, combined with building an application using Plotly Dash. We will cover the following topics:
- What is customer retention and its significance?
- Understanding RFM analysis.
- Getting started with Python.
- Implementing RFM analysis.
- Developing the application with Python and Dash.
- Conclusion and FAQs.
Customer retention is vital for any business aiming for success, as it is both cost-efficient and leads to increased spending and product trials. Research shows that acquiring new customers can be up to five times more expensive than retaining existing ones, and loyal customers are more inclined to explore new offerings and spend about 31% more than newcomers. This strategy is essential for ensuring continuous growth and profitability in today’s competitive landscape.
By the conclusion of this blog, we will have built a Python application. Below is a preview of the app:
Section 1.1: The Importance of Customer Retention
Customer loyalty and retention play a crucial role in a business's success, ensuring customers return for more purchases, thereby increasing revenue and acting as advocates for the brand. Retaining existing customers is more cost-effective than acquiring new ones, as loyal customers typically spend more and are more likely to try new products or services. Thus, they are essential for sustained growth, profitability, and a positive brand image.
Section 1.2: Understanding RFM Analysis
RFM analysis is an effective technique that helps businesses understand and categorize customers based on three critical factors: Recency, Frequency, and Monetary value. In simple terms, it allows businesses to identify their most valuable customers and strategize ways to keep them engaged.
- Recency (R): This measures the time since a customer last made a purchase or interacted with the business. More recent customers are often more responsive to marketing initiatives.
- Frequency (F): This indicates how often a customer engages with the business. Frequent purchasers are valuable as they represent consistent revenue.
- Monetary Value (M): This looks at the total amount a customer has spent. Recognizing and rewarding high-spending customers is crucial for profitability.
RFM scores are assigned based on these three factors, typically rated from 1 to 10, with higher scores indicating better recency, frequency, or monetary value. Customers are then segmented into various groups based on these scores, allowing for targeted marketing and retention strategies.
Chapter 2: Getting Started with Python
To set up our development environment for this project, follow these steps:
Step 1: Create a Virtual Environment
We will first create a virtual environment to manage our dependencies. Here’s how:
# STEP 1: Open the terminal and install the virtualenv library
pip install virtualenv
# STEP 2: Create a new virtual environment named riskmgt
virtualenv venv
# STEP 3: Activate the virtual environment
venvscriptsactivate
Step 2: Import Libraries
Next, we’ll load the required libraries for our project:
import dash
import pandas as pd
import numpy as np
import pathlib
import dash_table
import logging
import dash_daq as daq
import plotly.graph_objs as go
import plotly.express as px
import plotly.figure_factory as ff
import dash_core_components as dcc
import dash_html_components as html
import dash_bootstrap_components as dbc
from dash.dependencies import Input, Output, State
from datetime import timedelta
import layout
import dataPreprocess
Step 3: Load the Data
For our project, we will utilize the Kaggle dataset for E-Commerce data.
The video above provides a comprehensive tutorial on becoming an IBM Data Analyst, emphasizing the use of data analysis tools that can enhance your skills in this domain.
Implementing RFM Analysis
Having understood RFM analysis, we can now implement it using Python and build our application with Dash.
df['TotalSum'] = df['Quantity'] * df['UnitPrice']
snapshot_date = df['InvoiceDate'].max() + timedelta(days=1)
data_process = df.groupby(['CustomerID']).agg({
'InvoiceDate': lambda x: (snapshot_date - x.max()).days,
'InvoiceNo': 'count',
'TotalSum': 'sum'
})
data_process.rename(columns={
'InvoiceDate': 'Recency',
'InvoiceNo': 'Frequency',
'TotalSum': 'MonetaryValue'
}, inplace=True)
Further details on data distribution, cleaning, and wrangling can be found in our GitHub repository. After processing the data, we’ll apply specific thresholds to create segments.
if df['RFM_Score'] >= 9:
return 'Can’t Lose Them'
elif ((df['RFM_Score'] >= 8) and (df['RFM_Score'] < 9)):
return 'Champions'
elif ((df['RFM_Score'] >= 7) and (df['RFM_Score'] < 8)):
return 'Loyal'
elif ((df['RFM_Score'] >= 6) and (df['RFM_Score'] < 7)):
return 'Potential'
elif ((df['RFM_Score'] >= 5) and (df['RFM_Score'] < 6)):
return 'Promising'
elif ((df['RFM_Score'] >= 4) and (df['RFM_Score'] < 5)):
return 'Needs Attention'
else:
return 'Require Activation'
Now that we have processed the data, we can proceed to build the application.
Chapter 3: Building the Application
We will develop our application using Dash, an open-source Python framework ideal for analytical applications. Dash is built on Flask, Plotly.js, and React.js, making it perfect for data exploration, visualization, and reporting.
Building the Frontend
We will include a dropdown list populated with countries from our dataset:
html.H6("Select Country"),
dcc.Dropdown(
id="country-dropdown",
options=[
{"label": i, "value": i} for i in tmp_df[0]['Country'].unique()],
value='Select...'
),
We can also add other controls, such as radio buttons and DAQ toggle switches. For a complete guide on adding these features, please refer to the full code here.
Interactivity Between Components
The frontend, equipped with various widgets and placeholders, should interact seamlessly as user inputs change, utilizing callbacks and functions defined in Dash.
@app.callback(
Output("heatmap", 'figure'),
[
Input("category-type", "value"),
Input("country-dropdown", "value")
]
)
def update_pieChart(category, country):
# Function implementation
Similar callback functions will create interactivity between all visuals and data generated from RFM analysis.
Run the Application
To launch the application, navigate to your project directory in the terminal and run:
python app.py
You can then view the app in your web browser at http://127.0.0.1:8050/.
