Web scraping is a valuable skill because it allows you to extract data from websites that do not provide an API. This data can be used for a variety of purposes, such as price comparison, data analysis, or even lead generation.
Web scraping can be low maintenance because once you have a program that is scraping data, it can run on its own without needing much input from you. Additionally, web scraping can be speedy because a computer can scrape data much faster than a human can.
3-Data Reliability – Diverse & Rich Datasets
One of the primary advantages of web scraping is the accuracy of the data that you can collect. When you scrape data manually, there is always the possibility of human error. This can lead to inaccuracies in your data that can skew your results.
With web scraping, you can collect data automatically and with a high degree of accuracy. This is because web scraping tools are designed to follow set rules and consistently extract data. This means that you can be confident in the data that you collect, and you can be sure that it is accurate.
4- Easy to Implement
Web scraping can be a very effective way to get the data you need from a website. It is easy to implement and can be done with little to no coding knowledge. Additionally, web scraping can be done for free using a variety of online tools.
5- Complete Automation
It allows you to gather large amounts of data quickly and accurately, which can then be used for BI and machine learning applications. Because humans have biases and limitations, using machines to gather data is often more effective than collecting it manually.
Automated data collection is also faster and more efficient than relying on human workers, and it doesn’t require any special skills.
