Introduction

In this article, we will explore the classical way of scraping ecommerce websites. Web scraping is a powerful technique that allows you to extract data from websites. By following the steps outlined in this tutorial, you will learn how to scrape ecommerce websites using the traditional point and click system.

What is Web Scraping?

Web scraping is the process of extracting data from websites. It involves fetching the HTML content of a webpage and then parsing it to extract the desired information. Web scraping is widely used in various domains, such as market research, competitor analysis, and data aggregation.

The Classical Way of Scraping Ecommerce Websites

The classical way of scraping ecommerce websites involves mapping the site using the point and click system to set parameters for the scraper to follow and extract the target data. Let's dive into the step-by-step process:

3.1 Setting up a Sitemap

To begin, you need to create a new sitemap. Choose a name for your sitemap and copy paste the website URL which will serve as the starting point for the scraper. Once done, save the sitemap.

3.2 Adding Selectors

Selectors are essential in web scraping as they help navigate through the website's structure. Start by adding selectors to instruct the scraper to visit the women's and men's categories. Usually, this can be done by clicking on the relevant tabs on the website and saving them as selectors. However, if the website is complex, you may need to retrieve necessary data from the inspect tool. Enable the multiple log option if required and save the selector once done.

3.3 Creating Child Selectors

After adding the gender selector, you need to create a child selector to visit each of the subcategories within the chosen category. This child selector, called the category URL, will serve as another link selector. Click on the previously created gender link selector and navigate to the women's section. Save the category URL selector.

3.4 Implementing Pagination

On the product list page, you need to implement pagination to scrape data across multiple pages. In some cases, using the inspect log is necessary as clicking buttons on this page can select the previous page, disrupting the pagination process. Remember to designate two parent selectors: the category URL selector and the pagination selector itself.

3.5 Retrieving Product URLs

Continuing on the product list page, you now need to create the product URL selector. This selector will gather the URLs of individual products for further scraping. Similar to the previous step, designate the category URL selector and the pagination selector as parent selectors.

3.6 Gathering Product Information

To collect the necessary product information, open the first product page and select the product URL selector in the developer tool. Create text selectors to gather the product title, price, and color. Remember to designate the appropriate parent selectors for each of these selectors.

Pros and Cons of the Classical Way

Web scraping using the classical way has its advantages and disadvantages.

Conclusion

Web scraping using the classical way is a beginner-friendly approach to extract data from ecommerce websites. By following the step-by-step process outlined in this tutorial, you can scrape websites and gather the desired information efficiently. While it has its limitations, the classical way offers a straightforward method for extracting data without the need for extensive coding knowledge. Happy scraping!
