Table of content


    You can find plenty of useful information on the Internet, which is a real goldmine. However, finding the details in all those sites can be like finding a needle in a haystack.

    But now, there’s a solution! With special software, you can make collecting data from the web much easier. This is called web scraping, where bots do the work of extracting data and content from websites. You can even get help from services specializing in automating this data extraction process.

    Web scraping is like gathering information from websites and organizing it neatly. Imagine websites as books written in a special code called HTML. Web scraping services and tools turn this code into a well-organized structure, like putting information into a spreadsheet or a database. After that, you can easily work with the data to help businesses.

    Crawlers and Scrapers Team up as Info Hunters

    Think of it like this: if you want to collect information from websites without spending a lot of time copying and pasting, you use tools called a crawler and a scraper. 

    A crawler hunts for specific information online, like a smart computer program. Web scraping tools sometimes team up with crawlers to grab data straight from the World Wide Web using the hypertext transfer protocol (HTTP) or a web browser like Chrome. And a scraper? Well, that’s just a tool that pulls out data from websites.

    Types of Web Scraping Tools

    On the web, you may encounter different types of web scrapers, each with its own unique characteristics based on responsiveness and the technology at play. Check a few widely used web scrape types:

    1. Self-built web scrapers: As the name suggests, the users create these scrapers. However, it requires high proficiency in advanced programming skills, and the best thing you can do is tailor them to your needs.

    2. Pre-built web scrapers: Pre-built web scrapers are open-source software you can download and run on your machine effortlessly. 

    3. Browser extension web scrapers: These scraper extensions work directly in your web browser. They are user-friendly but may have limited features compared to other types.

    4. Cloud web scrapers: These operate on off-site cloud servers, freeing up your computer resources. They are convenient because you can run them without slowing down your computer, allowing you to focus on other tasks simultaneously.

    Common Web Scraping Techniques & Approaches

    Here are some ways people get information from the internet:

    1. Copy and Paste Like Humans: Someone manually copies specific data from a website and pastes it into a text file or spreadsheet.

    2. Python Web Scraping: Using the programming language Python, people can write code that finds and collects information from web pages. Other programming languages like Ruby, Java, C++, and JavaScript are also used.

    3. Browser-Based Scraping: Some techniques involve using web browsers to capture dynamic content created by scripts on the website.

    4. Semantic Annotation Recognition: This method uses special markers or metadata on web pages to locate and gather specific data.

    5. Computer Vision Help: With machine learning and computer vision, data can automatically be extracted from web pages.

    How does Web Scraping Work?

    To comprehend web scraping functionality, first consider that web pages are created using text-based markup languages such as HTML.

     A markup language basically sets up the structure of a website’s content. Because there are common components and tags in markup languages, it’s simpler for web scrapers to grab the information they want. Parsing through HTML is just one part of web scraping. After that, the scraper picks out the needed data and saves it. Think of web scrapers like APIs, which help different applications talk to each other and share data.

    Explore the data extraction solutions and operations of web scrapers with these key steps:

    1. Initiating an HTTP Request: The web scraper seeks permission to access a server containing the desired data.

    2. Extracting and Parsing Website Code: Upon obtaining access, the scraper navigates through the website’s XML or HTML, comprehending its structural composition.

    3. Code Parsing: The scraper meticulously dissects the code, identifying and extracting predetermined elements such as texts, ratings, classes, tags, or IDs.

    4. Local Data Storage: Ultimately, the web scraper securely stores the parsed data locally, having effectively processed the XML or HTML code.
