Do you know about free web crawlers?

The growing need for big data is pushing people deeper into the ocean of data.

 

Web crawlers play an important role in the preparation of Web pages for crawling. Today, the three main ways people access data on the Web are:

 

Take advantage of the public API provided by the site.

 

Write a web crawler.

 

Use automatic web crawler tools.

 

Based on my expertise in web scraping, I will discuss four free web scraping tools (web scraping, data extraction, data collection) for beginners.

 

What is the use of a Web crawler?


The purpose of a Web scraping tool is to crawl or grab data from a Web site.


It can also be called a web harvesting tool or data extraction tool (actually it has many nicknames, such as Web crawler, web crawler, data grabber, spider). It scans the web and searches the content quickly, and then collects data on the web. One benefit of a bulky Web crawler is that no programming skills are required. That said, it should be user-friendly and easy to use. §

 

Crawlers on the Internet help people gather a lot of information that they can access later.


A powerful web crawler should have the ability to export the collected data to a spreadsheet or database and store it in the cloud. In this way, the extracted data can be added to an existing database through the API. You can choose the web crawler as needed.
