Web scraping (also called automated data extraction) is the process of collecting structured information from websites using specialized software. In simple terms: it converts unstructured online content into organized datasets that you can analyze in spreadsheets or databases.
Key Fact
According to industry analysis, more than 70% of Fortune 500 companies use some form of automated data collection for competitive intelligence and market analysis. This technique has become a standard tool for data-driven decision-making.
What is Scraping in Data Analysis? Definition and Meaning.
According to the current definition agreed upon by experts, web scraping—also called data extraction—is the process of using a web scraper (a tool or script) to automatically gather information from websites.
- Scraping vs. Crawling: Crawling searches for and indexes pages, while scraping focuses on extracting specific data.
- Scraper vs. Scraping: The scraper is the tool, and scraping is the method.
In business terms, scraping converts unstructured web content into datasets ready for analysis.

How Automated Data Extraction Works (Step-by-Step Process)
1. HTTP Request
The software sends a request to the website’s server, simulating the behavior of a standard browser.
2. HTML Download
The server responds with the page’s HTML code, which contains both visible content and the site’s structure.
3. Parsing
The tool analyzes the HTML to identify patterns, specific tags (like <div>, <span>, <table>), or CSS selectors where the desired information is located.
4. Data Extraction
Specific elements are pulled such as:
- Product prices
- Names and descriptions
- User reviews
- Contact information
- Social media posts
5. Structured Storage
Information is saved in usable formats:
- CSV or Excel files
- SQL databases
- JSON formats for APIs
- Business Intelligence systems
Competitive Advantage
Automated collection can be up to 20 times faster than manual processes, eliminating human errors and enabling real-time updates.
Compared to manual or DIY work, automated scraping can be up to 20 times faster and much more accurate.
Real-World Examples by Industry
E-commerce and Retail
