This blog will focus on creating a web scraper that replicates the browser behaviors required to scrape Walmart product reviews and ratings. Selenium has several useful features that aid in the automation of web page testing. Instead of requiring human labor, we will employ some of these capabilities to automate our scraper for your use case. This information can also be utilized for BERT analysis and other NLP applications.

The technique of obtaining structured web data in an automated manner is known as web scraping. Pricing monitoring, price intelligence, news monitoring, lead creation, and market research are numerous applications of web scraping. You've done the same duty as a web scraper if you've ever copied and pasted information from a webpage, although on a small, manual scale.

The requests library's web scrapers are semi-automated and frequently hard-coded for a specific need. Selenium Bots, on the other hand, are used to replicate browser behavior for heavy sites that employ JavaScript. You will need to install the chrome driver to connect your website with the code mentioned in this blog. Consider hiring a person with the duty of collecting evaluations for your product from all of Walmart's 1000+ pages.

You can download the code.

Below mentioned is the step-by-step outline for web scrapers:

  • Establish the Selenium driver in the browser and acquire the product URL.
  • Locate the click tags to get to the Reviews page.
  • For the reviews, loop through the appropriate number of pages.
  • Clean up the data and deliver the outcome with all the review criteria.

Executing the Selenium Driver and Obtaining the Product URL on the Browser:

Initially, we will install the libraries required for the scraper:

pip install selenium
pip install beautifulsoup4

Construct the browser object by using the selenium webdriver to configure our previously obtained driver path. To open our product URL, use the get attribute.

Here, we will successfully install and execute the basic operation on Selenium.

Fetch the Review Page by Location the Click Tags

Visit the ‘See All Reviews’ Page

See All Reviews

We utilize Selenium's ActionChains to do all of the click actions. To retrieve the product-id from the URL, use implicitly wait for the command to allow the website to load even before the error occurs.

Select ‘Newest to Oldest’ from the Dropdown List

Newest to Oldest

Select, which replicates a manual process of picking an element from a list, from the dropdown category's Xpath. To access the reviews page, you will need to automate the steps.

For the reviews, loop through the appropriate number of pages.

appropriate number of pages

Review date, Reviewer name, Review title, Review body, and Ratings are the five elements you require for your evaluation. We can quickly locate the tags for each item.

Extracting the title of the reviews was difficult due to missing data. Scraping the titles of the reviews was difficult due to missing data. You will explore a few different approaches before deciding to utilize the length of the list containing the tags for the titles under the review header as a Boolean to determine whether we should add our tile list by the title or by a nan value.


Further, you will execute the below steps:

  • To loop through the review webpages in the desired range, use the browser object. We can control how many pages are cycled through.
  • Using the browser's page_source property, create a BeautifulSoup object.
  • For all review characteristics, initialize the lists within the loop. Using soup.findAll, append the lists in list comprehensions by identifying the attribute tags.
  • Build a dictionary of our categories, then attach this dictionary to our previously formed pandas Dataframe. Set the ignore_index=True property.

Clean up the data and deliver the outcome with all of the review criteria.

The DataFrame does not appear to be clean, and it is difficult to access. Converting the 'date' column into the DateTime index is a good decision here. For example, after December '20, You will search for the data. Your data is cleansed using the str.replace technique, which eliminates any undesirable substrings.

This completes your final output. To extract the product reviews, you will be able to construct a completely automated web scraper.

If you still wish to execute the code, here’s how you will initiate the project.

Implicit wait techniques might be problematic at times. As a result, you can use the waits function to provide an element that will be loaded before the script continues to run. Here's how to do it:


The following is an overview of the step-by-step approach we used to create a web scraper:

  • Install the Selenium driver and retrieve the product URL from the browser.
  • By identifying the click tags, you will be able to access the Reviews page. Then cycle through the needed number of pages for the reviews.
  • Cleansed the information and provide the outcome with all of the review criteria.
