How Does Web Scraping Work?

Behind every webpage is code — typically HTML. A scraper reads that code and identifies specific patterns. For example: Product name → inside a

tag

Price → inside a with a certain class

Review rating → inside a specific section

The scraper is programmed to “look” for these patterns and extract only what’s needed.

Popular tools and libraries include: Python-based frameworks like BeautifulSoup

Automation tools like Selenium

Custom-built scraping bots

The scraper sends requests to a website (just like your browser does), downloads the page content, and extracts the relevant data.

Web Scraping vs. APIs: What’s the Difference??

Some websites provide APIs (Application Programming Interfaces), which are structured ways to access their data. For instance, platforms like Twitter (now rebranded as X) provide APIs so developers can access certain data officially. When an API is available, it’s usually the cleaner and more compliant option. Web scraping, on the other hand, is often used when: No API exists, The API is limited, The data needed isn’t included in the API.
