Guide to Walmart Web Scraping: Tools and Techniques in 2024

Walmart is one of the largest retailers in the world, with a vast online store that offers a wide range of products at competitive prices.1 If you are an eCommerce business owner or market researcher, you might be interested in scraping Walmart’s product pages to monitor competitor prices, track market trends, or analyze customer reviews.

However, scraping Walmart can be challenging due to the website’s anti-scraping techniques, including CAPTCHA challenges, IP blocking, and user agent detection.

In this guide, we will provide step-by-step instructions on how to scrape Walmart’s product pages using Python and various other tools. Additionally, we will give some tips on overcoming common scraping measures to extract data ethically and legally.

What is Walmart scraping, and why is it essential?

Walmart scraping is the process of collecting data from Walmart’s product or category web pages. You can extract information, such as price data, product titles, descriptions and images.

It is possible to scrape Walmart using a no-code eCommerce web scraper or in-house web scraper. You can create a Walmart scraper for data collection using any programming language, including Python, and libraries such as Requests and Beautiful Soup. Whether you are using an off-the-shelf or in-house scraper, it’s crucial to stay within legal boundaries to avoid any potential legal issues.

Scraping eCommerce product pages can provide a wealth of valuable data that can assist businesses in the following ways:

  • Develop a more effective pricing strategy
  • Identify market gaps for growth
  • Monitor changes in pricing and promotions in real -time.

How to scrape Walmart product data & fetch product page

  1. Identify the product or category page that contains the data you need.
  2. Determine what type of data you want to retrieve from Walmart, such as product prices, images or reviews.
  3. Inspect the page source of the product page (Figure 1).

Figure 1:  Shows how to inspect the source code of the HTML content

To locate and select and element on a web page, you need to inspect the page source of the website.
  1. You can locate the HTML elements containing the data you need, such as product title or price, using the find() or find_all() methods.
  2. You can extract the text content of the element using the text attribute. For example, if you intend to scrape product title data from a Walmart product page, search for an h1 tag that contains the product title.
    If you are using Beautiful Soup, you can send a GET request to the Walmart product page and use the find() method to search for the first h1 tag on the page containing the product name data. Then, you can extract the text content of the h1 tag using the get_text() method.
  3. To scrape multiple Walmart product pages, you can use a loop to iterate over a list of URLs and scrape each page in turn. It is essential to bear in mind that you need to put time breaks between your requests to simulate human-like behavior. You can use the time. sleep() function to introduce time breaks between requests.
  4. If you are working with JSON data, you can load and parse it into Python objects using the JSON module. You can use the pd.json_normalize() function to flatten all JSON data into an actual data frame, making it easier to analyze and manipulate.
  5. You can use the built-in CSV module or third-party libraries such as Pandas or NumPy to export data to a CSV or other data formats, such as JSON or Excel.

Bright Data’s Walmart Scraper enables businesses and individuals to automate collecting data from Walmart’s website while avoiding anti-scraping measures. Check out the sample examples of scraping Walmart product pages obtained with the Walmart data collector.

Scraping Walmart Data with Python: A Step-by-Step Guide

  1. Set up your Python environment:
    • You must first download and install Python; you can download the latest version of Python from the official website.

You can also download BeautifulSoup 4 from the official website. However, installing BeautifulSoup with the pip command is usually easier and faster.

Once you have imported the library, you can start using its functions for pulling data. For instance, you can make a request to using Requests’ HTTP requests, such as PUT, DELETE, and HEAD. However, it does not support data parsing. You can use Beautiful Soup to parse HTML of the web page. Beautiful Soup is compatible with the built-in HTML parser.

  1. Make a request:
    • Specify the URL of the product page you want to fetch. Data fetching sends a request to the destination and receives receives a response containing the requested data.
    • Send a request to the target URL using the installed library. For example, you can use the requests.get() method to send a GET request to the specified Walmart product page.
    • Parse the HTML content of the response using an HTML parser, such as Beautiful Soup or a third-party Python parser, like HTML5lib and lxml.

Best practices for Walmart web scraping

It is important to note that Walmart, like many other eCommerce websites, employs anti-scraping measures such as CAPTCHAs to prevent web scraping activities. It is necessary to mimic the headers from your actual browser to avoid detection by the website you are scraping.

For example, when you send a request to the target server, you make your device information, such as your browser and operating system, available to the target website. The website will identify your activity as a script or an automated computer program such as a web crawler and block your IP address from accessing web services.

If you want to find out what is in your browser fingerprint and how unique your browser fingerprint is, you can visit AmIUnique (Figure 4).

Browser fingerprint is one of the web tracking technology used by websites to gain information about their visitors.

Note that mimicking headers alone may not be enough to circumvent all anti-scraping measures. Therefore, additional measures such as rotating IP addresses (e.g. residential IPs) or using headless browsers may be required. In this scenario, there are a few best practices to consider:

  • Rotating proxies: Walmart may block requests originating from specific IP addresses. You can use a rotating proxy server to bypass these restrictions. Rotating proxies allow users to change their IP address with each connection request, making it more difficult for Walmart to track and block your requests (Figure 5).

Figure 5: An overview of how a rotating proxy server works

Rotating proxies rotate clients' IP addresses frequently to avoid detection by the website they are browsing and scraping.

You can use proxies in conjunction with Walmart web scraping tools to speed up the data collection process. Oxylabs’ rotating ISP proxies assign a new IP address from the IP pool of datacenter and residential proxies. This makes your scraper appear more human-like and makes the scraping process less detectable.

  • Including a User-Agent: The ‘User-Agent’ header can help you avoid being detected as a web scraper by Walmart or other eCommerce websites implementing anti-scraping techniques. You can include a User-Agent header in your script using the Requests library in Python to mimic the headers from your actual browser. It is essential to ensure that your data collection activities are legal and ethical, and that you are not violating Walmart’s terms of service.
  • CAPTCHA solving: CAPTCHAs prevent automated scripts from accessing and scraping website content (Figure 6). To automate the process of solving CAPTCHAs, you can use a CAPTCHA-solving library to automate the process of solving CAPTCHAs, such as Pytesseract, or third-party CAPTCHA-solving services, such as Bright Data’s Web Unlocker.
