In simple words, Web scraping is like having a robot that can visit websites, copy information, and organize it neatly for you. This collected data can be really helpful for understanding trends, making predictions, or just getting information from the internet. But, just like with any tool, it's important to use it responsibly and follow the rules to avoid getting into trouble. It can be used in data analytics for several reasons like to fetch vast amount of data, for sentiment analysis, for automation, for market research and many more.

Web scraping, with Excel via web query or power query, Python & R (rvest, httr), extracts data from webpages. It offers diverse data sources, automates collection, enrich the datasets, and enhances data analysis. Experienced analysts view it as efficient, it provides accuracy, time-saving automation, competitive advantage, and enriched insights. Overall It's an essential tool for accessing vast web data, vital for modern data analytics.

Web scraping involves extracting data from websites. It's a technique used to gather information that isn't readily available through APIs or databases. Web scraping is valuable for data analytics because it allows analysts to collect large volumes of data from various sources, enabling them to perform in-depth analysis, gain insights, and make data-driven decisions.

When I heard about "Web Scraping" concepts and when I understood what is it? a Question came into my mind, "How this is going to help me as a data analyst?" Because the goal of web scraping is to get the data from web, but when it comes to us, how we can use it in effective way is important. People says these data helps in data decisions, and to make effective use of it, I suggest understand the context, why we need web scraping, and what we are going to do with the data. Then tools, I have used is Python Beautiful Soup, python's official website for Beautiful soup is also good site to start. Take one sample basic website, scrap it and then you will understand the process. then take some different website to scrap like amazon

Basic skills for web scraping include familiarity with a programming language like Python, understanding of HTML and CSS for navigating web pages, and knowledge of regular expressions for pattern matching. Commonly used tools include Python libraries such as requests for making HTTP requests, BeautifulSoup or lxml for parsing HTML, and Scrapy for more advanced scraping tasks.

Basic understanding of HTML and CSS. Familiarity with programming languages such as Python or R. Knowledge of web scraping libraries/frameworks such as BeautifulSoup (Python) or rvest (R). Understanding of HTTP requests and responses. Proficiency in handling data formats like JSON or XML.

To perform web scraping one should be familiar with programming languages like python or R or JavaScript along with some basic understanding of syntax of HTML and CSS. I personally prefer python with libraries like BeautifulSoup, Scrapy or selenium. Basic tools required are any browserto inspect webpages, and IDE like pycharm, VS code, Jupyter Ntebook, pycharm for running code.

Several free tools are available on internet, you can use Python on a easy way as per for comfort you can use R, JS . Python has popular library: Selenium, Requests, Beautiful Soup, Playwright, Scrapy or more. Several web extension are available for free.

I've personally found `WsCube Tech` YouTube channel to be incredibly helpful for learning web scraping. However, what really made the difference for me was diving straight into practicing it myself. Unlike some other technical topics, web scraping isn't overly complex. Once you have a basic understanding of HTML or XML tags and how to use them, you're good to go. I didn't wait to become an expert before trying it out; I simply watched a few YouTube videos, grasped the fundamentals, and started experimenting. My learning process involved scraping single pages initially, then progressing to multiple pages as I gained confidence. I even documented my project on GitHub and shared it on LinkedIn. So, if you want to try it then jump right in.
