How to Scrape eCommerce Competitors using cURL


website scraping


Competitor analysis is a crucial part of running an eCommerce business. It allows companies to gain insights into their competitors’ strategies and identify areas of improvement. With the rapid growth of the eCommerce industry, it’s undeniable that competition will become fiercer than it ever was. Global e-commerce sales are expected to reach $5.9 trillion this year


In this environment, competitive intelligence can help enterprises to stay ahead of their competitors. For many, web scraping is a strategy to help them boost their competitive level. Web scraping is the process of extracting data from websites. 


But how do you do it right using cURL? 


Using cURL for Competitor Scraping

cURL (Client URL) is a command-line tool for transferring data from or to a server. Here’s a detailed explanation of using cURL for web scraping to answer some common questions using cURL.


Install and Configure cURL


cURL provides a simple and efficient way to access website data and automate scraping. It allows the extraction of data from websites using the command line. 


When used for web scraping, cURL downloads a webpage’s HTML source code, which can be parsed and analyzed for data extraction. cURL also allows for the scraping of multiple pages in a sequence, which can be useful for large-scale data extraction.


It provides a higher level of automation in web scraping and can be integrated with other tools and programming languages. 


Identify Target Website


Choosing the right target website for web scraping is crucial for the success of a scraping project. It ensures that web scraping activities are legal and ethical. Web scraping is not illegal, but one must respect the target website’s terms of service and copyright laws


Avoid scraping sensitive or private information that could violate privacy laws. It’s best to choose websites that allow web scraping. 


Similarly, you should check if the target website has the data the scraper needs. Some websites may use technology such as JavaScript, making data extraction more challenging. 


Use cURL to Extract Data


When extracting data, use the appropriate cURL options. Note that some websites require specific headers or cookies to be set to access the data. Use the -H option to set custom headers and the -b and -c options to specify cookies for the request.


If the website requires authentication to access the data, use the appropriate cURL options to supply the necessary credentials. You can use the -u option to specify a username and password.


If the data you need is spread across multiple pages, handle pagination in your cURL command. This may involve specifying query parameters or using cURL with other tools to extract all the necessary data.


Handle Authentication and Anti-Scraping Measures


Many eCommerce websites use authentication and anti-scraping measures to prevent web scraping. These measures can include CAPTCHA, IP blocking, and user agent blocking. Many websites use session cookies to manage user sessions and prevent unauthorized access. 


Using cURL commands effectively enables web scrapers to access protected pages, avoid blocking or rate limiting, and scrape data more efficiently.


Store and Analyze the Data


After extracting the data using cURL, the next step is to store and analyze it. It can be saved as a file, on a database, or cloud storage service. The storage method choice depends on the volume and structure of the data. 


Web pages can have inconsistent data formats, so clean and normalize the data before storing it. For example, you may need to remove HTML tags, convert dates to a standard format, or remove duplicate entries.


Storing the data in a structured format such as CSV or JSON can make it easier to analyze later. Choose a format that can handle the size and complexity of your data.


If scraping data over time, consider using version control to track changes to the data. This can help identify trends and anomalies over time.


Key Takeaways

Competitive intelligence can give businesses insights into their customers’ needs and preferences. Analyzing the products and services allows companies to identify gaps in the market that they can fill.
