    In today's business world, smart data-driven decisions are the number one priority. For this reason, companies track, monitor, and record information 24/7. The good news is there is plenty of public data on servers that can help businesses stay competitive.

    The process of extracting data from web pages manually can be tiring, time-consuming, error-prone, and sometimes even impossible. That is why most web data analysis efforts use automated tools.

    Web scraping is an automated method of collecting data from web pages. Data is extracted from web pages using software called web scrapers, which are basically web bots.

    What is data extraction, and how does it work?

    Data extraction or web scraping pursues a task to extract information from a source, process, and filter it to be later used for strategy building and decision-making. It may be part of digital marketing efforts, data science, and data analytics. The extracted data goes through the ETL process (extract, transform, load) and is then used for business intelligence (BI). This field is complicated, multi-layered, and informative. Everything starts with web scraping and the tactics on how it is extracted effectively.

    Before automation tools, data extraction was performed at the code level, but it was not practical for day-to-day data scraping. Today, there are no-code or low-code robust data extraction tools that make the whole process significantly easier.

    What are the use cases for data extraction?

    To help data extraction meet business objectives, the extracted data needs to be used for a given purpose. The common use cases for web scraping may include but are not limited to:

    • Online price monitoring: to dynamically change pricing and stay competitive.
    • Real estate: data for building real-estate listings.
    • News aggregation: as an alternative data for finance/hedge funds.
    • Social media: scraping to get insights and metrics for social media strategy.
    • Review aggregation: scraping gathers reviews from predefined brand and reputation management sources.
    • Lead generation: the list of target websites is scraped to collect contact information.
    • Search engine results: to support SEO strategy and monitor SERP.

    Is it legal to extract data from websites?

    Web scraping has become the primary method for typical data collection, but is it legal to use the data?

    How to extract data from a website

    Manually extracting data from a website (copy/pasting information to a spreadsheet) is time-consuming and difficult when dealing with big data. If the company has in-house developers, it is possible to build a web scraping pipeline. There are several ways of manual web scraping.

    1. Code a web scraper with Python

    It is possible to quickly build software with any general-purpose programming language like Java, JavaScript, PHP, C, C#, and so on. Nevertheless, Python is the top choice because of its simplicity and availability of libraries for developing a web scraper.

    2. Use a data service

    Data service is a professional web service providing research and data extraction according to business requirements. Similar services may be a good option if there is a budget for data extraction.

    3. Use Excel for data extraction
