  7. Marketing Effectiveness: E-commerce businesses invest heavily in digital marketing campaigns. Data analysis provides insights into the performance of these campaigns, helping businesses allocate their marketing budgets more effectively and measure the return on investment (ROI) for each channel.

In summary, data analysis is the backbone of a successful e-commerce operation. It enables businesses to make data-driven decisions, adapt to changing market conditions, and create a seamless and personalized shopping experience for their customers.

In the following sections of this blog, we’ll guide you on how you can build your own web scraper for data collection from platforms like Walmart. The scraped material can be utilized for effective data analysis, allowing your businesses to have an advantage in the digital age.

II. Project Scope and Flow

Before we proceed on our web scraping journey, it’s essential to understand the scope of this project. In this guide, we’ll be focusing on crawling product data from Walmart’s Search Engine Results Page (SERP) and building a customized scraper which can be used for e-commerce analysis.

Before diving into the technical aspects, make sure you have the following prerequisites in place:

  1. Basic Knowledge of JavaScript and Node.js: Familiarity with JavaScript and Node.js is essential as we’ll be using these technologies for web scraping and data handling.

  2. Active Crawlbase API Account: You’ll need an active Crawlbase account with valid API credentials. These credentials are necessary to interact with Crawlbase’s web scraping service. Start by signing up to Crawlbase and obtaining your credentials from the account documentation. You will receive 1,000 free requests upon signing up that can be used for this project.

  3. Familiarity with Express.js: While optional, having some knowledge of Express.js can be beneficial if you intend to create an endpoint for receiving scraped data. Express.js will help you set up your server efficiently.

With these prerequisites in place, let us briefly discuss the project flow. It begins by sending a GET request containing a Walmart SERP URL to your Express server. The server, in turn, forwards this URL to the Crawling API, which crawls the Walmart SERP page, retrieving the crucial HTML content.

Once obtained, Cheerio steps in to extract vital product information. This extracted data is then handed back to the main function, ready for further processing. Finally, the scraped data is promptly sent back to the user, completing the seamless project flow, from user input to data delivery.

Project Flow

Now you are well-prepared to follow along with the steps in this guide. Our goal is to provide you with the knowledge and tools needed for seamless web scraping and e-commerce analysis. Let’s get started!

III. Setting Up the Environment

First off, create a Node.js project. This project will be the foundation for our web scraping environment. If you haven’t already, make sure Node.js is installed on your development machine.

Now, let’s set up your web scraping environment by installing some key dependencies. These tools will help us parse HTML, set up a server for receiving scraped data (if needed), and interact efficiently with web content. Here are the dependencies:

  • Cheerio Library: Think of Cheerio as your trusty companion for parsing HTML. It’s a powerful library that allows us to extract data from web pages seamlessly.

  • Express (Optional): If your project requires a server to receive and handle scraped data via an endpoint, you can use Express.js. It’s a versatile framework for setting up web servers.

  • Crawlbase Library (Optional): To streamline the process of fetching HTML content from websites, you can opt for the Crawlbase library. It’s specifically designed for interacting with the Crawlbase Crawling API, making data retrieval more efficient.

To install these dependencies, simply run the following command in your Node.js project directory:

1
npm install express cheerio crawlbase

IV. Creating an Endpoint

In this step, you’ll set up an Express.js server and establish a GET route for /scrape. This endpoint serves as the entry point for triggering the web scraping process. When a client sends a GET request to this route, your server will kickstart the scraping operation, retrieve data, and provide a response.

Creating this endpoint proves especially valuable when you intend to offer an API for users or other systems to request real-time scraped data. It grants you control over the timing and methodology of data retrieval, enhancing the versatility and accessibility of your web scraping solution.

Below is an example of how to create a basic Express.js GET route for /scrape:

const express = require('express');
const app = express();
const port = process.env.PORT || 3000;

// Define a route to handle incoming scraped data
app.get('/scrape', (req, res) => {
  // Process and store the scraped data here
  const scrapedData = req.body;

  // Respond with a success message or other appropriate response
  res.status(200).json({ message: 'Data received successfully' });
});

// Start the Express server
app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});

Save this code within your Node.js project and run node index.js to start the server.

Terminal Server

V. Fetching HTML using the Crawling API

Now that you’ve got your API credentials and your server is all set up with the required dependencies, let’s move on to the next step: using the Crawlbase Crawling API to grab HTML content from Walmart’s SERP page.

Here’s the deal: The Crawling API is like a tool that helps you ask websites nicely for their web pages, and they give you those pages in a simple form called raw HTML.

In this step, we’ll show you how to use the Crawling API. It’s like telling the API, “Hey, can you get me the Walmart web page?” and it goes and gets it for you. We’ll also show you how to use your special API credentials to make this happen.

To start, we’ll integrate the Crawlbase library to make a GET request to a specified URL (req.query.url), we have to insert the following lines into our main code:

const { CrawlingAPI } = require("crawlbase");

const api = new CrawlingAPI({ token: "YOUR_CRAWLBASE_TOKEN" }); // Replace it with your Normal Request token

app.get("/scrape", (req, res) => {
  api
    .get(req.query.url)
    .then((response) => {
      console.log(response.body)
    })
    .catch((error) => {
      console.log(error, "ERROR");
      return res.status(500).send({ status: "Failed", msg: error });

Instead of expecting data in the request body, this code uses the URL parameter to specify the Walmart SERP URL to scrape (which we’ll show later using Postman). It then logs the response from the Crawling API to the console and handles errors, responding with an error message and status code 500 if there’s a problem.

Here is the updated code snippet:

const express = require('express');
const { CrawlingAPI } = require('crawlbase');

const api = new CrawlingAPI({ token: 'YOUR_CRAWLBASE_TOKEN' }); // Replace it with your Normal Request token
const app = express();
const PORT = process.env.PORT || 3000;

app.get('/scrape', (req, res) => {
  api
    .get(req.query.url)
    .then((response) => {
      console.log(response.body);
    })
    .catch((error) => {
      console.log(error, 'ERROR');
      return res.status(500).send({ status: 'Failed', msg: error });
    });
});

app.listen(PORT, () => console.log(`Server is running on port ${PORT}`));

Run the server, pass the URL parameter to the route and you should be able to get the HTML response as shown below:

Terminal HTML Response

The HTML data you get from Crawlbase will be the building blocks for our next steps. We’ll use this raw HTML to find and collect the data we need using Cheerio and some custom tricks we’ll teach you.

By getting this part right, you’ll be all set to gather web data like a pro, and you’ll be ready to dive into the fun stuff – extracting and analyzing the data you’ve collected.

VI. Writing a Custom Scraper using Cheerio

In this step, we’re getting to the heart of web scraping. We want to get some really useful information from a Walmart Search Engine Results Page (SERP) URL, and here’s how we’re going to do it using Cheerio.

Imagine building your own tool to grab exactly what you want from a webpage – that’s what a custom scraper is. Our aim is to pull out important details like product names, prices, and ratings from the Walmart search results.

Walmart SERP Page

By creating this custom tool, you get to be the boss of how you want to collect data. We’ll show you how to pick and choose the information you need with selectors. It’s like you’re saying, “Please grab me the titles, prices, and ratings,” and it’ll do just that.

This hands-on approach gives you the power to fine-tune your scraping to match Walmart’s webpage structure perfectly. It ensures you get the data you want quickly and accurately.

const $ = cheerio.load(html),
  productData = {
    products: [],
    productsCount: 0,
  };

$('div[role="group"] div[data-testid="list-view"]').each((_, element) => {
  const title = $(element).find('[data-automation-id="product-title"]').text(),
    image = $(element).find('[data-testid="productTileImage"]').attr('src'),
    price = $(element).find('[data-automation-id="product-price"] .lh-copy span.f2').text(),
    currency = $(element).find('[data-automation-id="product-price"] .f6.f5-l:first').text(),
    reviewsCount = $(element).find('[aria-hidden=true].f7').text(),
    reviewStar = $(element).find('.flex.items-center.mt2 .w_iUH7').text(),
    deliveryMessage = $(element).find('[data-automation-id="fulfillment-badge"]').text().trim(),
    productBadge = $(element).find('.tag-leading-badge').text(),
    inventoryStatus = $(element).find('[data-automation-id="inventory-status"]').text() || 'In Stock',
    isSponsored = $(element).find('.lh-title > .gray.f7').text() ? true : false;

  productData['products'].push({
    title,
    image,
    price,
    currency,
    reviewsCount,
    reviewStar,
    deliveryMessage,
    productBadge,
    inventoryStatus,
    isSponsored,
  });
});

Essentially, this code traverses the entirety of the HTML content retrieved from the specified Walmart URL. It navigates through the various class elements within the page’s structure to locate the relevant data and places each piece of information into corresponding variables such as title, images, price, currency, and more.

VII. Streamline the Scraping Process

In this crucial phase, we bring together all the elements to create a smooth web scraping process.

Beginning with the /scrape endpoint, which manages requests on our localhost.

Then, introduce the code snippet that employs the Crawlbase library, ensuring that we can crawl the Walmart search engine results page (SERP) URLs without encountering blocks.

Lastly, we’ll incorporate our custom scraper, utilizing the Cheerio library, to provide us with a neatly organized JSON response for easy readability.

const express = require('express');
const cheerio = require('cheerio');
const { CrawlingAPI } = require('crawlbase');

const api = new CrawlingAPI({
  token: 'YOUR_CRAWLBASE_TOKEN',
}); // Replace it with your Crawlbase token
const app = express();
const PORT = process.env.PORT || 3000;

function parseProductsFromHTML(html) {
  try {
    const $ = cheerio.load(html),
      productData = {
        products: [],
        productsCount: 0,
      };

    $('div[role="group"] div[data-testid="list-view"]').each((_, element) => {
      const title = $(element).find('[data-automation-id="product-title"]').text(),
        image = $(element).find('[data-testid="productTileImage"]').attr('src'),
        price = $(element).find('[data-automation-id="product-price"] .lh-copy span.f2').text(),
        currency = $(element).find('[data-automation-id="product-price"] .f6.f5-l:first').text(),
        reviewsCount = $(element).find('[aria-hidden=true].f7').text(),
        reviewStar = $(element).find('.flex.items-center.mt2 .w_iUH7').text(),
        deliveryMessage = $(element).find('[data-automation-id="fulfillment-badge"]').text().trim(),
        productBadge = $(element).find('.tag-leading-badge').text(),
        inventoryStatus = $(element).find('[data-automation-id="inventory-status"]').text() || 'In Stock',
        isSponsored = $(element).find('.lh-title > .gray.f7').text() ? true : false;

      productData['products'].push({
        title,
        image,
        price,
        currency,
        reviewsCount,
        reviewStar,
        deliveryMessage,
        productBadge,
        inventoryStatus,
        isSponsored,
      });
    });
    productData['productsCount'] = productData['products'].length;

    return productData;
  } catch (error) {
    return error;
  }
}

app.get('/scrape', (req, res) => {
  api
    .get(req.query.url)
    .then((response) => {
      const parsedData = parseProductsFromHTML(response.body);
      return res.status(200).json(parsedData);
    })
    .catch((error) => {
      console.log(error, 'ERORR');
      return res.status(500).send({ status: 'Failed', msg: error });
    });
});

app.listen(PORT, () => console.log(`Server is running on port ${PORT}`));

Once a URL is provided, our server swings into action. This automated process ensures that you can access valuable information from Walmart’s search results in no time, making your experience more efficient and user-friendly.

VIII. Testing the Flow

To test our project, we recommend utilizing Postman as it provides a user-friendly graphical interface for making HTTP requests to APIs.

You can initiate a GET request to the local server, configured on port 3000, via the endpoint /scrape. Simply include a URL query parameter with a fully encoded target URL.

To encode a URL, you can highlight the URL string in Postman, click the Meatballs menu and select Encode URI Component.

Postman Encode URL

Complete Postman request:

1
http://localhost:3000/scrape?url=https%3A%2F%2Fwww.walmart.com%2Fsearch%3Fq%3Diphone%2B14%2Bpro
Postman JSON Response

So, when you make this GET request in Postman, it will be sent to your local server, and your server, using the Crawlbase library and Cheerio, will scrape the HTML content from the specified Walmart URL and return the relevant data as shown in the JSON response below:

X. Frequently Asked Questions

Q. How can businesses use data analysis from web scraping to improve their pricing strategies in e-commerce?

Businesses can use web scraping and data analysis to enhance their e-commerce pricing strategies by monitoring competitor prices, implementing dynamic pricing, optimizing prices based on historical data, identifying price elasticity, assessing promotion effectiveness, analyzing abandoned cart data, forecasting demand, strategically positioning themselves in the market, segmenting customers, and conducting A/B tests. These data-driven approaches enable companies to make informed pricing decisions, stay competitive, and maximize revenue while providing value to their customers.

Q. What are the best practices for data storage and management when conducting web scraping for e-commerce product analysis?

Best practices for data storage and management during web scraping for e-commerce product analysis include legal compliance, structured data formats, thorough data cleaning, cloud storage for scalability, regular data backups, encryption for security, access control, version control, defined data retention policies, monitoring and alerts, respectful scraping to avoid IP blocking, documentation of scraping processes, understanding data ownership, and periodic audits. Adhering to these practices ensures data integrity, security, and responsible scraping.

Q. If the search result have multiple pages, how do I scrape the next pages using Crawlbase?

To scrape multiple pages of search results in Crawlbase, you’ll need to utilize the pagination structure specific to Walmart. Walmart typically structures its URLs with a “page” parameter to navigate through search result pages. Here’s an example:

By modifying the “page” parameter in the URL, you can access subsequent pages of search results. When configuring your Crawlbase scraping task, specify this pagination logic and provide selectors or rules to collect data from each page.

Q. Is there a risk of your web scraper encountering blocks while scraping Walmart?

Yes, there is a significant likelihood of your web scraper facing blocks, especially if you’re not using a vast pool of proxies. While it’s possible to construct your own proxy pool, this can be both time-consuming and costly. This is where Crawlbase comes in, which operates on a foundation of millions of proxies, enhanced with AI logic that mimics human behavior to avoid bot detection and CAPTCHAs. By utilizing Crawlbase, you can scrape web pages anonymously, eliminating concerns about IP blocks and proxy-related challenges while saving valuable time and resources.
